Your great demonstration video informs & inspires people all over the world. This video is really 'step-by-step' DIY (do-it-yourself). Your air cleaning unit is practical & not expensive. Thanks.
Had an idea for the activated carbon. Mount a Long larger diameter pipe on the wall and put it in there. Then put fan on end to push air through. Then make it so you can rotate the pipe when you want to put a fresh side on the top. i bet you could get a large diameter shipping tube to make it out of too.
Anthrax! :-) Interesting seeing all these different approaches to fan dust-collector boxes popping up at pretty similar times. (you, Matthias, Jack...)
Excellent video It was great to watch a craftsman applying his skills - If I were on a ship to Mars this is the air filter/scrubber I would want next to me. Because I do not have your skills or tools mine will be a 20 inch box fan with a single filter slapped on the back.
Here's a crazy thought for the activated carbon. How about a perforated bottom 5 gallon bucket set over the outlet on your portable dust collector? Mix fill the carbon with other filler to reduce the total pressure drop. That dust collector should have enough static to push thru a sandwich layer of screen with the activated carbon/filler in between. That or the other idea of crushing your carbon up and coating one of your dust filters. It will load them up, but you could occasionally blow them out and re coat with your massive bag of activated carbon.
Good idea. It could work as the hepa filter in the extractor will capture the dust, and the exhaust should be relatively clean air. It also crossed my mind, that I could fill up a bag in my henry hoover with carbon and just turn that on.
Larger air flow isn't necessarily better for carbon filters. They have what is called residence time. In other words it takes a certain amount of time for the carbon to absorb the odors. If you force the air too fast it doesn't have enough time for the carbon to do it's job. Just keep that in mind if it doesn't work as well as you would expect.
I was speaking to the guy from British Engineering who checks our equipment at work. He didn't recommend lowering the air flow on down draft tables even for fumes. The more I thought about it I had to agree. Say the fumes are being produces quicker than the time it takes to draw through the carbon. Also lower air flow means not all the fumes will be drawn through the carbon. And finally - where your head was while the fumes were being made. Better to get it away from you. Also I have no way of measuring if it's working or not. Lol.
Very interesting! too bad the carbon didn't work. I guess what pushes the air in those cases needs to be more similar to a compressor than a fan. I'm waiting for the next one!
+Savvas Papasavva An idea to increase the air flow for the carbon: a larger box, using two identical fans in a push/pull configuration, one post-filter perhaps?
GREAT ideas, I’m thinking about building a similar unit. QUESTION, won't the carbon slowly sink to the bottom of the box? Maybe just flip the unit upside down every week?!?!
I've been toying with this idea for many months, more since mathias put his video out. Each time I revisit the ideas I struggle to find the fitters. ...where did find yours?
The crazy thing is the extent to which the blades of the fan are absolutely not optimized. Just flat surfaces. A 3D printed one would have been amazing.
Any later attempts related to using activate carbon or managine VOCs? Unfortunately, a lot of the excitement about air filtering plants were based off of NASA studies in confined areas that share little relevance with the many studies done by public health and environmental agencies that have shown disappointing results in real living environments.
Hello! I am interested mainly in VOCs as well. But I want to create my own purifier. However I can't go this elaborate. So my question is, Would it be possible to put some filter on a box fan (as a lot of diy'ers do on youtube) but the difference is somehow use a filter that would remove VOCs? What do you think the best way to do this is? HEPA / Furnace filter on the back of the fan, then activated charcoal on the front?
I have no idea if this is feasible, or practical in terms of expense. However I saw someone made a comment which is "Greek" to me, but may be helpful to you. We need an updated Charcoal filter fan for VOCs if anyone can figure it out. thanks! "Works very well to scrub and remove unwanted compounds from oleoresin being prepped for distillation. Scrub at 100f Filter through silica bed and 1 micron boro paper."
Instead of using 2 2in filters why not use a single 4in-5in thick filter, I don't know if they are as common across the pond but if you want activated carbon , at least here in the states several manufacturers make filters with activated carbon impregnated media.
Great video, thanks for that :-) Where did you get the filters from? I've not been able to find them in the UK - perhaps I just don't know how to refer to them though!
Carbon usage: 1) in a big tank, make some moonshine and filter the drops or 2) get an even bigger tank, fill it with terrapins and filter their poo ...
aham, I saw, yes it's working. You mention that your filter is G4, my air purifier is with G4 and F9, and the pre filter (g4) looks clean, 10 months already, It is a little dark but there is no wood dust. I am starting to think that my shop is very clean, I am trying to catch everything from the sorce (I have and top and bottom dust collection on my table saw) basically my table saw is dustless, may be because of that I do not have so much wood particles in the air, still have but not so much may be. ;]
I think the negative effects of not using LEV is a long term one - but in the short term having things in place, including air scrubbers will noticeably improve the quality of the air.

Nice detail of the rubber to prevent vibrations. Great work, mate.
Thanks for the video , you made this 5 years ago , till now what is your opinion ? Would you make any changes? Great video as always

Awesome 👏 but shouldn’t it be activated carbon or even better, bamboo? How is it performing today??
Nice project! I loved and appreciated the CNC magic!!! HAHA

Maybe an impeller fan would be better?
+Savvas Papasavva probably!

You can buy activated carbon pre-filter sheets which might work in this application.

Search for pleated filters!

Good working Savas Pasa. How m3 air filtering in one hour? Could you say? Thanks.
Shots fired! Love it ;)
Rubber grommets for the fan blade cage?
The crazy thing is the extent to which the blades of the fan are absolutely not optimized. Just flat surfaces. A 3D printed one would have been amazing.
Best CNC video example I've seen :>).
Whoa. Good on you man, thanks for the video.
jolly good !
Keep on trucking ! (from France)
I liked that project, well built too. I have a small shop (12'X24'), would I need a system that large?
God Bless my friend.
Mine isn't much bigger. Guess something is better than nothing.
Does this build have a laminar flow?

Please share the the description of the equipments used!
Does that activated charcoal bed 4:14 work as a activated charcoal air purifier? Is it the same thing?
Do you think is better put the carbon filter in front or behind the hepa filter? I mean near or far from the fan?
How about industrial-grade exhaust fan? 2400 m3/h, 30 cm in diameter. Could be better - more blades at a different angle.

I got a 20x20 box fan, filter, and some tape... took about 30 seconds
You know taking a bit more time might actually mean the box fan gets something out of it too...
I have no idea if this is feasible, or practical in terms of expense. However I saw someone made a comment which is "Greek" to me, but may be helpful to you. We need an updated Charcoal filter fan for VOCs if anyone can figure it out. thanks!

But what were the results of the VOCs?

Tea. Pleated filters on eBay.
Γειά σου μάστορα.Είσαι μάγκας.Μπράβο!!!
Could You put links, on Amazon, to filter and carbon?
I see you have found someone else, I thought I was your biggest fan!
Haha but my mother is my biggest fan!
If you used a Squirrel Cage fan instead of the blades you would get lots more air flow
Ah we call them a centrifugal fan. I was thinking of making another filter which I can connect to my inline fume fan.
Carbon usage: 1) in a big tank, make some moonshine and filter the drops or 2) get an even bigger tank, fill it with terrapins and filter their poo ...
For the air to go through the carbon media, u need at least 2 inches static fan, i don't think the fan u use is working
Actually I do not like your air purifier (I think the blower is not proper for this job) but how is it after 3 months, do you run it on a daily... ?
There's a pic on my Instagram of how much dust it collects - I'm very happy with it.
aham, I saw, yes it's working. You mention that your filter is G4, my air purifier is with G4 and F9, and the pre filter (g4) looks clean, 10 months already, It is a little dark but there is no wood dust.

Good job.
Hi, what engine did you use for the fan and where did you buy it?
May i ask, how often you need to clean or replace the filters
It depends on use - I might give it a clean ever couple months but my use is not that much.
you get a thumbs up for 'alakazam'!
What are those metal wood fasteners called at 3:44??
Simple, very sweeeeet
how many watts is the fan?
what is that air filter you used at min 1:29?
Do you notice a difference in your health with this filter?
I think the negative effects of not using LEV is a long term one - but in the short term having things in place, including air scrubbers will noticeably improve the quality of the air.
@@SavvasPapasavva Do you notice a difference in YOUR health? Thanks
@@inthehouse9062 Why do you care about my health?
@@SavvasPapasavva This is part of some research I am doing
@@inthehouse9062www.hse.gov.uk/lev/case-studies/school-case-study.htm
what do you use in 3:43 to link the wood?
They are called v nails.
Glue a small child to the fan cage to mitigate resonation.
The wala kazam didn't work for me.
1:42 whoouuu
I wanted to see the VOC TEST with VOC TEST equipment, all I got was a stinking wind meter an da waste of my time being bored to death.
Voc?
Volatile Organic Chemicals.
amezing
dude, to boring!!
too not to. That is strictly your opinion. I thought it was great so did the other 794 people who watched it.
