I rate this top 5 things newbies need to be taught because odds are they won't figure it out on their own. However you utilize another thing they need to learn which is much more important and you utilize in this tutorial without mentioning why it works. That is the fact that bridges, valves and the like have priority on your pipes/vents. So if you put a bridge on a pipe the liquid going through always takes the bridge if it can but will pass by it if it can't. This is so critical to know to make effective pipe and vent set ups and I bet its so basic experienced players don't think of it anymore.
@@GabrielCazorlaPersson1 Consume power but is 100% fooled proof. If any exits is blocked, the filter stop which prevents mixed up. The Pipe element sensor and valve also consume very little power (if none at all because of the small window of activation and small power cost of the valve) but you need to have a Continuous flow of gaz in both direction for it to work. If one is backed up, you're screwed... Same thing with the mecanical filter (filter in this video).
@@GabrielCazorlaPersson1 i was just pointing out the fact that there is nothing wrong with a newby using the powered filter for there first play through.
It's awesome and clever..but I mean..the actual filter costs barely any power haha, and especially if it's for your electrolyzer setup with hydrogen gens
@@KaladinVegapunk You aren't wrong, those are fair points. It doesn't sound like much but cutting out unnecessary power use makes a HUGE difference. Three filters costs about half of a coal generator, plus whatever it takes to cool the filters and the generator. Another thing to remember is that it has different properties. This doesn't block the main line when the filter output is full, sometimes you want that.
@@KaladinVegapunk you’d be surprised how much filters cost after a while. I had a base with 4 oil wells (no petrol boiler yet) and I ran out of oil. Just removing the filters and going a pipe sensor filter arrangement instead allowed me to run the base again with just petrol and not run out of oil. It definitely adds up! Haha
I agree, I have played this game for so long and never knew about this! Using this and the infinite gas storage hack ensures that the line never gets backed up and it literally costs nothing, I can pipe gasses out when I need from the gas storage and it just continually runs. I use it to filter carbon dioxide from the base (no carbon skimmer needed) and then to sort and store all my excess chlorine from the rust oxidizer
First time I saw the mechanical filter was on the forum quite a while ago. It changed a lot of stuff. I use them in my electrolyzer rooms all the time. One oxygen filter on each vent and another hydrogen filter with a relief at the end for whatever backs up. One of the best game mechanic reliant designs.
I often have full pack pipes that overload these filters but a great way around it on these systems is to install a valve and limit the input to 995-999g/s. 1 less way to overpower the filter! 😉
That's a good solution for many uses. But it can cause problems for other uses, like if you have full packets of alternating gasses it breaks them all into 999g and 1g packets. That situation reduces the capacity of the input pipe to 50%.
Used this today for a couple of housekeeping (basekeeping?) tasks, sorting sluice liquids and random gases at the bottom of the base. Works very well with the mini-pumps and a clock sensor! Thanks for all the vids, you make this game so much more rewarding to play!!!
Wanted to leave a like and a comment saying thank you for such an awesome tutorial! Short, simple, and to the point! I've been using this inside my SPOM rooms and although it can be a pain to seed, it's reliable for hundreds of cycles. I've started using a filter to prime the system to speed up the process because it can be tricky to get the right gas in there when setting up the system.
Fantastic explanation. I've been using these filters for ages, but always had to check a reference to copy. I now feel I understand enough to easily build from scratch.
If you are *"height restricted"* but can expand the filter 1 tile sideways, you can put the *Valve UNDER the bridges.* In that way the whole filter becomes 2x3 size, BUT you need 1 tile in the middle for the output pipe, so effectively the filter size becomes 2(+1)x3 or 3x3 sized. (I absolutely love using this filter type, a ZERO POWER filter that is "easily" created even in the start of the game :)
I appreciate your humility in not taking any credit for this idea, but I’ve played this game off and on for _years_ and never known about this filter. So big props from me all around for sharing it here with us!
I had a whole chain of powered filters sorting out a mixed pipe of gas and dumping into compressed storage. Now with a bit of extra space expenditure, I can save using all that power, and the filters keep working even in an outage
Great video! I used this based on somebody else's video on building a Self Powered Oxygen Machine (SPOM). They used this to filter Hydrogen into a gas storage container. And it worked great. But I didn't realize what it would do when the gas storage filled. I had been building near the bottom of my base for several cycles and when I came back, the whole top of my base was flooded with hydrogen.
This has probably been commented already, but you could fix the 1g leakage problem by putting in another valve before the filter, and set that to 999g. That way you will get packets that are always able to merge with the filter's packets
Pretty interesting way to setup a filter in the early game or if you're very tight on space or far from the electrical grid, but I don't care for the extra setup difficulty.
Great. Newbie here. I've never seen this before. I've not tested this but I think you could use a valve set to 999g in the input line to prevent oxygen continuing on the main path, this would also remove the need for the second bridge. And in order to prevent the oxygen from backing up in the filtered line you can always have the gas pipe continue from the reservoir input to a place where you are sure it won't overpressure (like into space).
just tested the valve set to 999g. It works, but the throughput rate is significantly decreased. This is because each 1000g packet is split into two packets by the valve: 1g and 999g. Each of these two packets takes the same amount of time to process as the original full 1000g packet, which can get through with no problem in the setup shown.
This is amazing! also, if there's too much O2 for it to handle, just filter the CO2 instead, it works wonders I'm already using this to filter the few H2 that manage to sneak on my O2 line out, it's a most amazing energy-free failsafe
This is clever. I wouldn't say this is an exploit though. It's working logically because of the rules of the game physics. If this is an exploit, then maintaining vacuum with a liquid lock, regulating heat transfer with open/closed airlock doors, or creating an endlessly circulating coolant loop with pipes are too, because none of these make sense outside of the game's physics. And so is 80% of the other builds you can make.
This is how I feel about things like “infinite storage” too. The entire game is a physics sandbox to a degree and trying to emphasize real-world physics on it is hilarious to begin with. Plus it’s single-player, so who are you cheating? You’re still using the built-in game mechanics in reliable, consistent systems that work for hundreds of cycles to improve your base.
Thanks Tony for the great explanation. But there will be a caveat. If your pipe to the gap reservoir is full, the oxygen will continue to flow in the origin pipe, defaulting the purpose of the filter.
Indeed, you are right. This is either a feature or a vulnerability depending on what you are using it for. Every filter has different behaviors and its nice to be able to pick the right one.
I haven't tested it, but hypothetically a solution to the overflow problem with this filter would be to have a low-priority loop that moves the excess oxygen back onto the unfiltered gas line at a higher priority. This would ensure that the overflowing oxygen locks up the throughput until the oxygen in the gas reservoir gets used up.
You would have to throttle the unfiltered line at the point of the filter with a valve set to 999 g/s, though, since that's how much oxygen would be passing through the overflow path.
To avoid the 100% 1000 seconds pipe of oxygen, won't it work if you use 2x separate valves system, gobbling up the reservor. It's a bit of a stretch but the gas filter 100% uses no power.
I used this filter a while ago, but stopped, as it always buggered out when i reloaded the game. The filters would get a another element in it and would need to be reset. It's a while ago though and I've learned a lot since then.
I know this video is old, but if you use a filter at 9999 and a 1gram filter you can have it loop back on itself so it can back up and stop the pump if you so choose instead of allowing the gas to pass a backed up filter.
add on to this 3:30 1000 ticks is not that many if you think about it but you can extend it infinently by elongating the exit of the valve and adding more bridges each bridge will add 1000 more ticks but the better way is just add a 2nd valve that only allows 999 threw sure you wont get a full packet but it fixes the issue
Also, there are new automation features in the game. You could just use a shutoff to turn off the pipe for one second every 10-or-whatever cycles, with a little creativity I'm sure it could be done in a way that only uses power for the 1 second.
By the way there's also somewhat more complex variant of mechanical filter that works exactly like standard filter, i.e. it blocks when either output blocks. That fixes the problem of the simple mechanical filter that if you block the filtered output, packets of the filtered element will continue through the main pipe. forums.kleientertainment.com/forums/topic/86047-perfect-mechanical-filter/
You could avoid the overflow of the input by putting a gas valve on that pipe and setting it to 900g/'s. You will have 10% less throughput but no over flow incase it is really important for it not to happen.
For some applications that works pretty good. But, for example, if you have alternating full packets of gasses then it slows the pipe down 50% because it breaks them all into 900g and 100g packets.
@@tonyadvanced6315 yeah you're right. If there is input from several different places, those pipes would need to be joined together in one before it passes the valve,else putting in the valve wouldn't make a difference, because of alternating packets of liquid/gas. Didn't think of that yet. The joys of pipe mechanics. Good day to you mate.
The unfortunate problem with this filter is that it requires that the gas pipe being bridged into it occasionally do have the gas being filtered out. I tried to set one up to catch the very occasional bits of hydrogen that would get caught in the oxygen pumps for my SPOM. Well, gradually the hydrogen put into the filter to start it ran out (went to my tanks) and the oxygen from my oxygen lines went through it and, also, into my tanks, where they were fed to my hydrogen generators. The generators weren't too happy about it. But a great idea where you know you'll be getting a reliably mixed feed of gases.
You built it wrong. Because of the 1g being constantly replaced into the loop it should never 'run out'. The filtered output (in this case your hydrogen) should be coming out PAST the white input of the valve. Like how the video has it set up. Basically, before throwing it into the gas line towards your generators, it'll take 1g again to keep it 'primed' in the loop.
@@diamondelement4140 I followed the video exactly and retried twice. Always failed eventually for me. So either he's not showing something clearly enough for me, or it's no longer a reliable design due to game updates.
@@fuzzypumpkin7743 but brother it never fails for me and logically through my explanation or the videos it should never fully take out that last 1g of the element. I know you said you made it exact but are you absolutely sure? Are you bridging into the loop? And is the loops output going up from the white input? (Like in the video) The filtered output has to be after the white output so it has a chance to grab 1g again for the loop like I explained. I want to help out a fellow ONI player
@@diamondelement4140 Honestly, I was attempting this TWO MONTHS ago. I'm not interested in retrying. I've started making my O2 production via a soggy Rodriguez that automatically filters the hydrogen and oxygen into different chambers. So, no more need for filters for O2 and I filter other gases so rarely I don't care about the power cost.
Have close to a thousand hours in the game and never knew this... huh... 😂. I use sensors and valve shut offs to filter stuff. Cheaper power than actual filters but not as cheap as this!
While this is a nice short video, it would have been handy to show things like how to prime a pipe with a certain gas, but most important is that you forgot to mention that this filter immediately falls apart when the pipe feeding them goes empty. In other words, these filters will function great as long as there's gas flowing, but when that stops for just a second, they all go empty. Would've been good to know before I tore down my other filters and put these in place with a lot of effort to prime them. :/
@@tonyadvanced6315 If that's the case, then I must have done something wrong, and it's worth another shot. Apart from priming the pipes, it's a pretty simple build, so I'm curious if you have any idea what could have caused my gas-filters to go empty? Are there any (bad) conditions that would make them do that? (My setup was simple: A gas-pump sucking in ambient air, pushing it through a set of filters, and catching the gasses in reservoirs). Thanks for the reply btw! edit- I did have some problems priming the pipes. It was my first time having a go at it. I ended up with different sized packets in the filter. Some 1g, some 2g. Maybe that's what caused them to malfunction?
I use these with mini pumps in several key locations to keep the pesky CO2 moving to the bottom of the base. Also in all my fluid tanks because some times you just can't prevent different liquids from getting dumped in the same tank. Additional notes: 1) you can set the valve to 0.1 g, that is the smallest unit it can go 2) put a bridge at the output side to help the gas/liquid decide direction 3) Gas Valve(unpowered) can merge gases at it's output; the Gas Shutoff(powered) does not merge gases on the output 4) the Gas/Liquid Bridge has wierd logic haven't figured out; some times merges and some times does not merge #2 video shows the output once every 2 sections of pipe. I'm pretty sure, will have to check, that with the bridge on the output you will get gas in every section of pipe on that side. #3 I noticed the note on the shutoff wiki page about the valve, but that bit of info is missing from the (unpowered) valves wiki page. This was almost a disaster one time! An auxiliary line of hydrogen with small amounts backed up my SPOM. Replaced the bridge with a valve and that stopped the back up. #4 With bridges I'm not sure exactly what is going on and the wiki doesn't explain anything about merging lines. I believe some times a bridge further up the line can affect what is happening where you are attempting to put a bridge into an intersection or joining of lines. Watch carefully and you may need to use a Valve there or further back in the line instead of a bridge
Wait, why am i bothering with trying to estimate the complex gas movement algorithms whims when i could just use this to filter my SPOM? Trying to figure out which tile a hydrogen will move to after it was created sucks ass. This way i can just pump it out no matter what and easily separate them... Thanks!
Yeah, but there are possible problems that come with that approach. For example, if you have oxygen and CO2 alternating in a pipe, and a full packet of oxygen hits the valve then it will let through 999g and then 1g. So it takes twice as long to go through the valve, and your pipe is effectively moving gas at 50% capacity.
Just be careful with this method because the game as a vile habit of deleting the 1g packets going around when you load the game. That mean that at one point, you'll load a save game and all your pipes filters will be f*cked up because you'll lose a few packets of oxygen and they'll be replace by CO2 (as exemple in your video). So a filter that you've set up for oxygen COULD eventually change for something else if you're not careful. Personnally, this would be the last filter I use.. The pipe element sensor and valve right after is the best when you have a CONTINUOUS flow. If the main backs up, you can have problems there too.. Gaz filter is the best but yeah.. use a lot of energy.. but it never miss and will stop the flow if it can't expel the gaz in either the exhaust pipe (filtered or other) which is a nice security. Nice video though!
@@tonyadvanced6315 Keep up the great work! I've been playing the game for more than 2 years now and always a few good tricks to go. All options have their use, advantages and disadvantages. :) Maybe they've fixed the deleted packets things.. the last I've heard of it was a while ago (like summer 2018). If so, this is a great filter but I would still be careful. The number of time my filters has messed up because of little details I didn't though or forget about (mainly the backed up pipes...). Can lead to a gazy or liquid mess /mixed up easily if not careful.
You limited the filter loop to 1 gram couldn't you reduce the pipe before the loop to 999 grams to ensure no packet drop and then there would be no need for redundancy?
Yes, but it can suck depending on the situation. If you have alternating full packets of O2 and CO2 then the 999g filter will break all the packets into a 999g pkt and a 1g pkt, using up twice as much space in the pipe and slowing everything down by 50%.
That's a good way to go in situations where you don't mind the new problems it introduces. Imagine a pipe that has full packets of O2 and CO2 alternating. A valve would let through 999g of a packet, and then the remaining 1g, effectively reducing the capacity of the pipe to 50%.
@@tonyadvanced6315 ah, that is true. I was thinking of this in a situation where you're sorting a variety of mixed gases. Although I suppose that if you had two gases, both in high volume, you'll get a lot of full packets.
@@suzyb1499 With a variety of mixed gasses it seems like there's not much reason to worry about the 999g/s limitation anyway. I think the best time to add a 999g/s valve is when you are filtering a pipe that is almost always the same element and only rarely has a "wrong" packet to filter out. Because, that's when the problem is a problem, and that's also when having the valve doesn't create more issues. (Because like-elements merge and you can get 999g/s packets through the valve continuously.)
You are right, a filter could be use and this is more complicated. The benefit of using more difficult filters is that they use much less power and don't need as much cooling. Just three gas filters use about half of a coal generator, so it's very much in your interest to learn to use low-power alternatives. The game gives you the tools as soon as you have the automation researched.
@@tonyadvanced6315 wow thanks for quick reply! yeah i tried setting it up just now and the carbon seemed to move in and the oxygen stopped itself moving through but i did set it up differently
Imagine having to break the game's physics to save 120 W of power. Cool find, but this is on the same level as "deleting" asteroid debris with mechanical doors - a cop-out.
I find that one ONI player's cool design is another ONI player's unacceptable hack. I was once dead-set opposed to door compressors, for example. But the abundant varieties of clever things that can be done in the game have swayed me to believe that ingenuity like this is basically encouraged.

this filter now works perfectly because storage containers have automation outputs, so there's no way for it to overflow.
I prefer the element sensor + valve filter for long term. But this is great for early game.

I wonder if something has been fixed/changed. I've never had any trouble.
had some problems with it too. because i had it on storing big amount of gases it became a real issue and i stopped using it for this kind of stuff.
This is a great reference. I've played a LOT of ONI, but for some reason pipe dynamics don't stick in my brain.
Nice, I have times where a gas filter is a waste of power for little amounts of gas I am trying to keep apart.

I know this video is old, but if you use a filter at 9999 and a 1gram filter you can have it loop back on itself so it can back up and stop the pump if you so choose instead of allowing the gas to pass a backed up filter.
add on to this 3:30 1000 ticks is not that many if you think about it but you can extend it infinently by elongating the exit of the valve and adding more bridges each bridge will add 1000 more ticks but the better way is just add a 2nd valve that only allows 999 threw sure you wont get a full packet but it fixes the issue
You can also set the valve to .1g, which makes it last 10,000 seconds. That's 16+ cycles.
Also, there are new automation features in the game. You could just use a shutoff to turn off the pipe for one second every 10-or-whatever cycles, with a little creativity I'm sure it could be done in a way that only uses power for the 1 second.
By the way there's also somewhat more complex variant of mechanical filter that works exactly like standard filter, i.e. it blocks when either output blocks. That fixes the problem of the simple mechanical filter that if you block the filtered output, packets of the filtered element will continue through the main pipe.

You could avoid the overflow of the input by putting a gas valve on that pipe and setting it to 900g/'s.
You will have 10% less throughput but no over flow incase it is really important for it not to happen.
For some applications that works pretty good. But, for example, if you have alternating full packets of gasses then it slows the pipe down 50% because it breaks them all into 900g and 100g packets.
@@tonyadvanced6315 yeah you're right.
If there is input from several different places, those pipes would need to be joined together in one before it passes the valve,else putting in the valve wouldn't make a difference, because of alternating packets of liquid/gas. Didn't think of that yet.
The joys of pipe mechanics.
Good day to you mate.
Well I didn't know it, thanks a lot!
I just noticed this phenomenon myself today.
Nice trick. I'm gonna keep using the gas filter tho
Wow that's clever. This is why humans took over the planet- collaboration.
could just add a purge vent of sorts down the line that vents to where ever
The unfortunate problem with this filter is that it requires that the gas pipe being bridged into it occasionally do have the gas being filtered out. I tried to set one up to catch the very occasional bits of hydrogen that would get caught in the oxygen pumps for my SPOM. Well, gradually the hydrogen put into the filter to start it ran out (went to my tanks) and the oxygen from my oxygen lines went through it and, also, into my tanks, where they were fed to my hydrogen generators. The generators weren't too happy about it. But a great idea where you know you'll be getting a reliably mixed feed of gases.
You built it wrong. Because of the 1g being constantly replaced into the loop it should never 'run out'. The filtered output (in this case your hydrogen) should be coming out PAST the white input of the valve. Like how the video has it set up.
Basically, before throwing it into the gas line towards your generators, it'll take 1g again to keep it 'primed' in the loop.
@@diamondelement4140 I followed the video exactly and retried twice. Always failed eventually for me. So either he's not showing something clearly enough for me, or it's no longer a reliable design due to game updates.
@@fuzzypumpkin7743 but brother it never fails for me and logically through my explanation or the videos it should never fully take out that last 1g of the element.
I know you said you made it exact but are you absolutely sure?
Are you bridging into the loop?
And is the loops output going up from the white input? (Like in the video)
The filtered output has to be after the white output so it has a chance to grab 1g again for the loop like I explained.
I want to help out a fellow ONI player
@@diamondelement4140 Honestly, I was attempting this TWO MONTHS ago. I'm not interested in retrying. I've started making my O2 production via a soggy Rodriguez that automatically filters the hydrogen and oxygen into different chambers. So, no more need for filters for O2 and I filter other gases so rarely I don't care about the power cost.
@@fuzzypumpkin7743 okay brother but if you want to retry it ever just type here I'll help if you need it
The guy who comes up with this idea: IQ = *Vegeta:- IS OVER NINE THOUSAND!
Thank you so much for this!
wtf this is cool as hell TY
Have close to a thousand hours in the game and never knew this... huh... 😂. I use sensors and valve shut offs to filter stuff. Cheaper power than actual filters but not as cheap as this!
I`ve seen a lot of clips with explanation about filter, but they was difficult for me. Now - how can be so simple?
This is very smart, but I'm not sure if I want to use it because it seems exploit-y.
You can set your valve to 0.1g, no need to waste a whole gram.
Then your filter can run for 10,000s with full packets before wasting any.
damn i pogged so hard thanks bro
While this is a nice short video, it would have been handy to show things like how to prime a pipe with a certain gas, but most important is that you forgot to mention that this filter immediately falls apart when the pipe feeding them goes empty. In other words, these filters will function great as long as there's gas flowing, but when that stops for just a second, they all go empty.
Would've been good to know before I tore down my other filters and put these in place with a lot of effort to prime them. :/
There is no need to keep a steady supply to the input pipe. The .1g packets are content to run in a circle forever.
@@tonyadvanced6315 If that's the case, then I must have done something wrong, and it's worth another shot.
Apart from priming the pipes, it's a pretty simple build, so I'm curious if you have any idea what could have caused my gas-filters to go empty? Are there any (bad) conditions that would make them do that? (My setup was simple: A gas-pump sucking in ambient air, pushing it through a set of filters, and catching the gasses in reservoirs).
Thanks for the reply btw!
edit- I did have some problems priming the pipes. It was my first time having a go at it. I ended up with different sized packets in the filter. Some 1g, some 2g. Maybe that's what caused them to malfunction?
Awesome! Thanks for sharing :)
Dam, that's awesome.
Thanks broh
I use these with mini pumps in several key locations to keep the pesky CO2 moving to the bottom of the base. Also in all my fluid tanks because some times you just can't prevent different liquids from getting dumped in the same tank. Additional notes:
1) you can set the valve to 0.1 g, that is the smallest unit it can go
2) put a bridge at the output side to help the gas/liquid decide direction
3) Gas Valve(unpowered) can merge gases at it's output; the Gas Shutoff(powered) does not merge gases on the output
4) the Gas/Liquid Bridge has wierd logic haven't figured out; some times merges and some times does not merge
#2 video shows the output once every 2 sections of pipe. I'm pretty sure, will have to check, that with the bridge on the output you will get gas in every section of pipe on that side.
#3 I noticed the note on the shutoff wiki page about the valve, but that bit of info is missing from the (unpowered) valves wiki page. This was almost a disaster one time! An auxiliary line of hydrogen with small amounts backed up my SPOM. Replaced the bridge with a valve and that stopped the back up.
#4 With bridges I'm not sure exactly what is going on and the wiki doesn't explain anything about merging lines. I believe some times a bridge further up the line can affect what is happening where you are attempting to put a bridge into an intersection or joining of lines. Watch carefully and you may need to use a Valve there or further back in the line instead of a bridge
3:25 I just use two such filters set to 500 each.
This is nifty
Wait, why am i bothering with trying to estimate the complex gas movement algorithms whims when i could just use this to filter my SPOM?
Trying to figure out which tile a hydrogen will move to after it was created sucks ass. This way i can just pump it out no matter what and easily separate them...
Thanks!
amazing! now if I put a gas valve before the gas enters this filter and throttle it to 999g, will it fix the issue of that 0.1% failure?
Yeah, but there are possible problems that come with that approach. For example, if you have oxygen and CO2 alternating in a pipe, and a full packet of oxygen hits the valve then it will let through 999g and then 1g. So it takes twice as long to go through the valve, and your pipe is effectively moving gas at 50% capacity.
You can just set up 2 of these, that would solve a problem
Thanks!
thanks for the info
このゲームは面白いけど、科学の特徴を盛り込んでいるなら当然混ぜれば化学反応（変化）を起こすような仕組みにしてほしいですよね。
例えば塩酸と水酸化ナトリウムが化学反応（変化）して水分子と食塩が出来るなど。
あと、真空状態にしてるのにH2Oが膨張して分散し浮遊しないのはいただけないかな。
it could be very annoying to play and break some mechanics though
Just be careful with this method because the game as a vile habit of deleting the 1g packets going around when you load the game. That mean that at one point, you'll load a save game and all your pipes filters will be f*cked up because you'll lose a few packets of oxygen and they'll be replace by CO2 (as exemple in your video). So a filter that you've set up for oxygen COULD eventually change for something else if you're not careful.
Personnally, this would be the last filter I use.. The pipe element sensor and valve right after is the best when you have a CONTINUOUS flow. If the main backs up, you can have problems there too.. Gaz filter is the best but yeah.. use a lot of energy.. but it never miss and will stop the flow if it can't expel the gaz in either the exhaust pipe (filtered or other) which is a nice security.
Nice video though!
That all sounds like an accurate analysis to me. I never had a problem with deleted packets but I wouldn't doubt it. Thanks.
@@tonyadvanced6315 Keep up the great work! I've been playing the game for more than 2 years now and always a few good tricks to go. All options have their use, advantages and disadvantages. :)
Maybe they've fixed the deleted packets things.. the last I've heard of it was a while ago (like summer 2018). If so, this is a great filter but I would still be careful.
The number of time my filters has messed up because of little details I didn't though or forget about (mainly the backed up pipes...). Can lead to a gazy or liquid mess /mixed up easily if not careful.
powerful!
Great video. But have they patched this? I can't seem to get it to work.
Thank you
You limited the filter loop to 1 gram couldn't you reduce the pipe before the loop to 999 grams to ensure no packet drop and then there would be no need for redundancy?
Yes, but it can suck depending on the situation. If you have alternating full packets of O2 and CO2 then the 999g filter will break all the packets into a 999g pkt and a 1g pkt, using up twice as much space in the pipe and slowing everything down by 50%.
@@tonyadvanced6315 I should of known better to think it was that easy
Ad a valve before getting to the filter set the valve to 999g
So there is always 1 gram of room left
great thx explanation
What if there isn't any oxygen for a while, and the loop becomes empty?
That can't ever happen. The 1g packets in the loop will just go in a loop forever.
It's important to fill the loop with (in this case) oxygen first. As the valve takes priority (in this case) 1g of gas always remains in the loop.
I just saw the cycle number...🙃
Couldn't you just put a valve limiting the unsorted gas to 999g/s to ensure it doesn't have the full packet problem?
That's a good way to go in situations where you don't mind the new problems it introduces. Imagine a pipe that has full packets of O2 and CO2 alternating. A valve would let through 999g of a packet, and then the remaining 1g, effectively reducing the capacity of the pipe to 50%.
@@tonyadvanced6315 ah, that is true. I was thinking of this in a situation where you're sorting a variety of mixed gases. Although I suppose that if you had two gases, both in high volume, you'll get a lot of full packets.
@@suzyb1499 With a variety of mixed gasses it seems like there's not much reason to worry about the 999g/s limitation anyway. I think the best time to add a 999g/s valve is when you are filtering a pipe that is almost always the same element and only rarely has a "wrong" packet to filter out. Because, that's when the problem is a problem, and that's also when having the valve doesn't create more issues. (Because like-elements merge and you can get 999g/s packets through the valve continuously.)
Couldn't you just like... Use a filter pipe? Maybe that's ignorant to ask but like this seems way more complicated.
You are right, a filter could be use and this is more complicated. The benefit of using more difficult filters is that they use much less power and don't need as much cooling.
Just three gas filters use about half of a coal generator, so it's very much in your interest to learn to use low-power alternatives. The game gives you the tools as soon as you have the automation researched.
This works with liquids too?
hm it doesn't seem to work anymore unless I had set it up wrong
I haven't played in a while but maybe they changed something in the last couple weeks.
@@tonyadvanced6315 wow thanks for quick reply! yeah i tried setting it up just now and the carbon seemed to move in and the oxygen stopped itself moving through but i did set it up differently
Is this a oxygen or a water filtration?
If only I knew what game this was...
Heh. Hmm. Whoops. I guess I'll edit the title a bit.
Imagine having to break the game's physics to save 120 W of power. Cool find, but this is on the same level as "deleting" asteroid debris with mechanical doors - a cop-out.
I find that one ONI player's cool design is another ONI player's unacceptable hack. I was once dead-set opposed to door compressors, for example. But the abundant varieties of clever things that can be done in the game have swayed me to believe that ingenuity like this is basically encouraged.
Doesn't seem to work any more
