That is a heck of a lot of mechanical/packaging engineering. The people who designed this really have an excellent ability to work in three dimensions.
This looks like a very expensive design. All those connectors to be wired and fitted. So much electronics for such a simple function. It appears to lack a user replaceable air filter. I think it is over engineered.
The electrical and mechanical design is next level. So much happening in a small package. I would have never guessed from looking at the outside that so much was going on in the inside. Thank you for sharing with us.
That is some very complex and sophisticated engineering for an ionizer. I'm sure the engineers and designers had fun with it. It makes me want to overcomplicate something simple... like, maybe I'll design a rolling pin that has 50 parts and complex assembly that works and looks like a giant wooden dowel, but at 500x the cost. haha
Hehe, 200 quid of internal spinning weights and guv'nors instantly wiped out by a usbC socket full of bread dough and flour :) Clearly needs a wireless charging dock.
I'm actually relieved to see the amount of internal shielding. As cars become increasingly complex, with high-speed and low-speed data buses and individual modules scattered about that all need to communicate on wired networks, errant noise can wreak havoc on a vehicle's operation. Not to mention the potential impact on radio reception (AM/FM/DAB/HD RADIO/RDS) and cell phone reception... And not just on the installed vehicle, it could very well be enough to interfere with a nearby vehicle. (I've had a vehicle's stock turn signals cause FM static in time with the on-state of the lamps, great job on shielding, Stellantis!) Having that precisely-shaped shield, and seeing it tied to the vehicle's chassis ground via the screw and negative power lead, proves they've actually put significant thought and engineering into this product, in the hopes of minimizing any potential issues. This wasn't some "generic ionizer module shoved into a cup-holder-sized case," this was a product that had some intelligent teams working together to build an excellent product. As I've come to expect from a subsidiary of Matsushita.
Regarding the high voltage diodes. I remember one time getting some fairly high voltage diodes in an assortment of all kinds of parts I think it was like a boxes of surplus components through some company or another or they have gotten these from someone else in a bunch of stuff can't remember. However the how voltage diodes absolutely had it stacks of the eagle discs you could clearly see this since the diodes were basically translucent plastic tubes with end caps. By the way one time I was curious about internal construction of a large ball like diode so it took a hammer to it literally. Load behold it was a disk like structure with Leeds attached in some manner as well. From what I've heard I don't know if this is correct or not just what I've heard from others. Is essentially the discs or punched out of a sheet of the PN Junction material that's essentially a flat sheet or a ribbon something along this lines. And basically these are just stacked in some manner as to be able to create a high voltage diode of Norris ratings depending on the number of discs stacked. I even saw something once I don't know how old this component was or was from it's just something that I got from somebody as just something interesting it was a resistor that was built in a similar fashion except pallets of a carbon black material who knows what exotic piece of equipment this was from for the age of it. Also with the diodes mentioned before that I received there was a bunch of these what looks like glass enclosures resistors except the prices did not look like a carpet material more like a gold color I'm suspecting Patricia temperature sensor porcelain quite exotic. A lot of really Oddball and interesting components in the mix. So which of course we're not even labeled . By the way speaking of high voltage inverters light in this video except on a lower voltage scale. I saw this three-letter component in something in the back of my brain told me to connect 12 volts to two different pins keep in mind this is on a circuit board that was just a drunk board may have you been Surplus as well. And I heard a bit of a wine running at 12 volts and realize this was some type of inverter what's the my surprised it was able to run neon pilot light bulbs weird for sure. Oh and yeah there was that time that was trying to fry the it's not out of a calculator that failed after years. Turn the diode into a light bulb note not an LED but incandescent bulb essentially silver high-pitch sound from the thing too just oddball. If you can't fix it or replace it for much have some fun with it! And yeah one time was working on a calculator that had rechargeable batteries oopsie with that board how to remove an oopsy. Bear in mind this is before lithium batteries were used. Yep I accidentally short circuit in that one burn the traces clean off the board however not the problem not repairable not even worth trying to do so much wrong with it not to mention would have to find a way to use some something other than the charge Jack provided I had never seen a plug like that before or since alone odd voltage of adapter think it combines both power and battery charging in same power supply if I'm not mistaken 3 wire plug low voltage of course
Way back in the 1970s, I repaired a color TV that used a similar (but much larger) ceramic & deposited carbon resistor to supply the focus voltage for the CRT. The manufacturer connected the thing from the CRT anode voltage (30KV!) to ground, and tapped the resistor for the focus voltage. As one might imagine, the resistor opened up after a while. Replacing the resistor restored the focus.
Thinking back to the early 2000s, there were still CRT televisions. As soon as I turned it on, white smoke filled the room. I unplugged it and disposed of it. We had a short in ours. It didn’t trip the breaker.
Could you imagine that most Trinitron tubes from the mid 1980's onwards, had a similar resistor inside the tube, as part of a potential divider for the horizontal static convergence...
It's crazy to think someone sat and thought about how to build this thing, All the wire and chips and board is one thing but the housing with all the tracks and pieces and holes to allow airflow and then it clips together to make 1 unit, The wire and power system is 1 thing but someone designed all that housing, When I take things apart im just as amazed some time with the housing because someone sat there and figured all this out on a paper '' computer ''
It's not just that someone designed the shell. They passed the model to the next department where it got redesigned into a mouldable shell that considers the assembly procedure as well. Probably number of test moulds to dial in tolerances. Pretty advanced stuff.
Wildly complex. Thanks Big Clive! Looking it up I found one on Amazon for almost $100 Pricey little guys. Apparently Lexus includes the Nanoe tech in the AC systems.
Ex Toyota tech here, Toyotas have it too (same business as Lexus after all), never been so deep though. Funnily some older Toyotas used competing Sharp Plasmacluster units!
I would have thought the carbon granules would be there to adsorb any large charged molecules which have been split apart by the corona discharge. That gives the ozone longer to work on them and once neutralised they would be released back to the air.
As I was walking this a couple of things occurred to me. That resistor reminded me of the thin film resistors that are used in multimeters to make a voltage divider. And the way they make the corona with the ball reminded me of the top of a tesla coil in a way. It would make a place for electrons to collect to a specific potential before you actually got some kind of discharge or current flow.
I looked up the patents and it seems the rounded tip may be related to panasonic's special sauce- dunno if its the case for this one, but the electrode is designed to be cooled by a peltier module so that it condenses water from the air. The high voltage then atomizes the water that collects on the tip, creating a mist of negatively charged water droplets. Edit: come to think of it, that explains the ground potential electrode too, as it would be in contact with it, the peltier module would best be at a similar potential to the electrode to avoid arcing, and a 0v,5v power supply is easier to make than a -10000v,-10005v power supply
Parents still use a Panasonic 50" plasma they bought in 2006. A heavy, robust piece of equipment. I believe it was assembled in Mexico, Panasonic must have really nailed down their QC. And they have an 80's Panasonic boombox that's repeatedly baked and froze every year in the garage but still works fine (except for the tape player who's belt long ago disintegrated).
There is a design school never to use a few simple components if a lot of complex ones will do the job, but this air purifier is extreme: all that electronics to control a high voltage generator and a fan.
It seemed to me like an exercise in emulating transistors with mcus 😂 I guess that's what you get when universities shift focus from circuit theory to embedded systems
With the rounded emitter you get a better distributed and less intense electrical field or corona and I wonder if this increases the life of the electrodes and makes if more efficient?
It might be over engineered but at least it acts as a reminder of what we lost when we turned our backs on real Japanese engineering - think of that next time your Chinese tat breaks down after two weeks 😂
Are those two extra wires going to a Peltier element? Some of these units cool the tip to encourage condensation to form. I also wonder if the carbon granules are more to do with moisture capture? Very interesting device.
As a kid I had a Panasonic cassette tape recorder/player, that thing got dropped, wet, or dirty on a regular basis. It survived until well past my teens, my mom used it to record college lectures. I think once I replaced the drive belt.
i'm watching this on a panasonic tv. ive never had a bad panasonic household product. 30 years ago my panasonic cordless drill was a bit wanting. but back then all cordless brands were a bit wanting.
@@tncorgi92 I have my father's 1970s Panasonic 8-track recording deck, it still works really well - I need to adjust the azimuth and slap a new belt on it (original belt), but it DOES work, amazingly none of the lamps have burned out yet! Our 1978 Panasonic 15" CRT TV finally died in 2013, probably something easily-repairable, but its failure was what shoved us into the HDTV era. Sometime in the late-80s, the dial lights burned out, so it was either tune-with-the-VCR, or shine-a-flashlight-at-the-dials. 😆
I've had 4 Panasonic TVs in over 35 years they never broke down, just kept going until technology made them obsolete. CRT, the Standard Def Plasma , HD Plasma and now an OLED.
Such an overload of components and complex design. I just roll down my windows for 5 seconds and all the air in my car has been replaced by fresh outdoors air.
Inventory control manager: How do we get rid of all these components that have been here for years, including these fans and bags of carbon? Engineers: We'll make a complicated filter for cars that looks like a cup but really just blows air on the driver.
@@ekummel Usefulness and quality? You are kidding, right? It's a useless piece of junk! ... It may be Panasonic branded, and have some decent parts in it, but it's still useless! ... Anyway, that's my opinion, and clearly yours differs, but everybody is entitled to one! Big Clive has "usefulness and quality!" ... Everybody loves Big Clive!
I've been thinking. In the last 3 or 5 years a product category popped up which didn't exist before, cordless airbrush. A tiny little compressor that is sat right underneath the airbrush itself, and these are normal airbrushes used in scale model painting. They are scary cheap, and while i've seen plain USB ones in the past, now they all include a battery, seems like. I wonder what the compressor and power unit is built like.
The little air pumps in desktop and wrist worn blood pressure cuffs (sphygmomanometers) are tiny little swash-plate diaphragm pumps, very cute and might be similar to the airbrush units. The pressure sensors are sometimes quite elaborate because they measure the cuff pressure AND the pulse beat signal with the same sensor so it needs a wide linear range and fast response to small changes. The capacitive ones are sometimes just a membrane over a PCB conductor that drives an RC oscillator.
@@KallePihlajasaari I have had several wrist worn manometers fail on me (material fatigue in the flexible cuff sandwich) so i have torn them down, and been curious about harvesting pressure measurement IC from them to use for something of a kind. But the pumps in those are absolutely tiny. It looks like the airbrush has a lot more stuff inside probably a bulkier motor. I wonder how much or how little i can get away with, been thinking of putting a foot switch controlled air pump on my desk, i could use the inlet as vac tweezer and the like and use the outlet for airbrushing.
I'm in New Zealand and have a used Japanese import Toyota Corolla which has a Panasonic Nano E air con system. My wife is Japanese and she says the pronunciation is actually 'Nano E'
I guess another reason for wanting to capture the ozone with the carbon filters, besides people getting a bit weary from the smell is that ozone is very corrosive. While it's small amounts, if the unit is sitting in a car it'll be surrounded by all manner of plastics and polymer coatings that might start to degrade over time in the immediate vicinity of where the unit is. I don't know how much effect it might have, but in theory it might which is probably enough for marketing to slap a couple of filters in there.
I had a repurposed corona discharge wire from an old analogue photocopier that was continuously running in a workshop at a pretty high voltage and current (would glow an eery blue in the dark) and after about a year or so when I went to examine it I could see that all nearby iron parts had a fine coat of rust. Ozone is a real problem for many things, plastic as you say is quite vulnerable and can become brittle with no signs of other damage so adding the ozone filter is a good idea in a closed space like a car. I think I saw a hint of an 8 hour timer so you could turn it on when you exit the car and it would sanitise it over night and the ozone would not build up.
I wonder if this is what that “Delusional Design” eBay thing with the strangely sturdy welded case was trying to copy. Particularly the blower-type fan mounted upright in the middle reminds me of that. The difference being that this is actually functional.
Those soldered headers really confused me for a minute when I was fixing my onkyo receiver. Board that held the relay/speaker connections had one, whereas other stuff in it had ones that could be unplugged. Tugged at it, wiggled all the usual stuff. Wouldn't come off and then realized it wouldn't and de-soldered it.
18:16 That is the kind of diagram in which physics teacher delight - drawing a van der Graaf generator with small pieces of ali foil spurting off its top. Maths teachers have their equivalent - the saggy boob diagram.
panasonic has room air purifiers with nano e. and a lot of their air cons got that too. i have 5 panasonic aircons with the nano e function and i think they all use the same board for everything hence all that selection option with jumpers.
I have a question about LEDs. I know this posting isn't about LEDs, but I don't know how else to contact you. In the standard replacement LED bulb for home incandescent bulbs, what makes them flicker. Since they usually have a circuit inside and always some sort of capacitor, does the cap cause the flicker most of the time when it starts to go bad? Wondering...
I have a few LED lamps that failed flickering, they all had one of the LED chips go bad with seemingly an internal thermal related intermittent contact.
I have opened up a couple that had a similar fault with a slowish blinking as soon as they got hot. There is a inline RF choke (plump green resistor looking thing with coloured bands) with a resistor across it that fails open when hot and then the internal capacitor charges slowly via the resistor and then makes a blink. After opening it I could start and stop the flickering by poking the RF choke with a stick to make and break the connection.
Looks (to me) like the "needle" is a tiny globe to produce a much larger corona and therefore, a larger a number of ionised particles flying around. Rather over the top for a car unit.
Very complex little piece of technology! I'm guessing this thing actually does what it says it does. A massive amount of design work went into creating this little device! I researched this a bit and it sounds impressive and was quite a bit cheaper than I expected. Seeing how this thing is built now has me thinking about buying one. We see a lot of devices out there that make all sorts of claims and when you tear into them, you know the claims are mostly hype. I don't think that is the case here,
Ionisers are notorious for making dust get attracted to grounded surfaces. This would make dust particles attach to the unit instead of your car. I think it is a nice idea. However it is most likely to be there to deduce radio interference from the corona discharge.
Thanks Clive. Only you can take a hundred quids worth of complicated tech and reduce it down to just a small willy and a lady garden. 😂😂😂 Brilliant. Cheers 🍺
No. Some ozone generators use similar circuitry, but they are very different things. A real ioniser will put out less than natural ambient levels of ozone.
Trust Panasonic to make something complex. But I've looked at their room unit demo, very impressive. They left some things (i remember dog food) in a sealed room with one of their bigger nanoe units, completely odorless room when you went in. Then saw the price, nevermind.
I usually find your videos easy to follow, but this is a pretty complicated device. Is it maybe overengineered a bit? I'm seeing a lot in it that feels somewhat unnecessary.
Thanks, quite interesting. Does this mean it's sold as a disposable device? With no easy way to change those carbon thing-a-me-bobs, they will become possibly blocking the airflow over time and so what when they're blocked up... throw away jobby?
I was wondering that about the carbon filters too. Maybe the carbon absorbs ozone for a while (to pass safety limits) before the activated carbon is all used up.
Usually, large particles like dust are first removed with a conventional filter, then activated carbon removes smoke, fumes & other molecules. If air is filtered through a carbon filter only, I guess dust will eventually clog it up.
@@davadoff Yeah unless the carbon thingees are actually some kind of catalyst. Either way it's going to block up, I guess management realized their little fan wouldn't have had enough guts to pull air through a changeable filter. So they just didn't bother.. Simples !!
I googled Panasonic Nanoe: "The 1800-watt blow dryer uses technology to to infuse moisture-rich ions into hair, helping minimize frizz and enhance hydration and shine." Very odd indeed :)
Had to read that several times before my damaged brain got it right... at first glance I thought you said "emulating transistors with mucus". Obviously, that's snot right 😂😂😂
That is a heck of a lot of mechanical/packaging engineering. The people who designed this really have an excellent ability to work in three dimensions.
I have some wireless Panasonic webcams for the barn that are going on 20 years old and noticed some similar packaging cues. Interesting consistency
It just goes to highlight the difference between a good brand and the others.
@@CommanderZx2nice to see that the name brand isn't just the same guts as the cheapie, re-badged, as is so often the case.
Look at the difference between Chines made stuff and Panasonic, the Chinese have as few parts as possible and Panasonic as many parts as possible.

It is well over complicated, not even bother to use a connector, you still think so?
@@lifeai1889 The amount of over engineering is impressive for the small space. No necessarily better. LOL. Must have been designed by NASA.

Definitely something Mork would be calling Orsen about.....! 😉
Such an overload of components and complex design. I just roll down my windows for 5 seconds and all the air in my car has been replaced by fresh outdoors air.
Maybe the "blunt needle" is to reduce any erosion of the point due to the discharge. (but I would expect that to reduce it's effectiveness)
Inventory control manager: How do we get rid of all these components that have been here for years, including these fans and bags of carbon? Engineers: We'll make a complicated filter for cars that looks like a cup but really just blows air on the driver.
That is a very well put together item. You can really tell the quality of this item!
Quality, but useless? 👎🤣
@@marcse7en how do you figure? The device seems to have quite a bit of usefulness and the quality of the device seems to reflect it's usefulness.
@@ekummel Usefulness and quality? You are kidding, right? It's a useless piece of junk! ... It may be Panasonic branded, and have some decent parts in it, but it's still useless! ... Anyway, that's my opinion, and clearly yours differs, but everybody is entitled to one!
Big Clive has "usefulness and quality!" ... Everybody loves Big Clive!
I've been thinking. In the last 3 or 5 years a product category popped up which didn't exist before, cordless airbrush. A tiny little compressor that is sat right underneath the airbrush itself, and these are normal airbrushes used in scale model painting. They are scary cheap, and while i've seen plain USB ones in the past, now they all include a battery, seems like. I wonder what the compressor and power unit is built like.
The little air pumps in desktop and wrist worn blood pressure cuffs (sphygmomanometers) are tiny little swash-plate diaphragm pumps, very cute and might be similar to the airbrush units.
The pressure sensors are sometimes quite elaborate because they measure the cuff pressure AND the pulse beat signal with the same sensor so it needs a wide linear range and fast response to small changes.
The capacitive ones are sometimes just a membrane over a PCB conductor that drives an RC oscillator.
@@KallePihlajasaari I have had several wrist worn manometers fail on me (material fatigue in the flexible cuff sandwich) so i have torn them down, and been curious about harvesting pressure measurement IC from them to use for something of a kind. But the pumps in those are absolutely tiny. It looks like the airbrush has a lot more stuff inside probably a bulkier motor. I wonder how much or how little i can get away with, been thinking of putting a foot switch controlled air pump on my desk, i could use the inlet as vac tweezer and the like and use the outlet for airbrushing.
Trippy looking at the reverse image of the circuit board
Very cool! Thanks Clive!❤
Neat and good job and agree there is much more subtle complexity to the Japanese products more well thought out.
You missed the most amazing part. The nanoe module has a tiny peltier underneath the needle that cools it and creates condensation on the knob.
I sussed that out afterwards. Initially I couldn't work out what the near short between the base wires was for.
"Needle" tip may be coated with some rare metal activator to help for better corona discharge.
Panasonic engineer: To (hopefully) protect my job I fit some complexity! I bet 2 555 chips would have done the same?
Fabulous piece of work but it's an ioniser with a fan and timer ... why so complicated?
I'm in New Zealand and have a used Japanese import Toyota Corolla which has a Panasonic Nano E air con system.
My wife is Japanese and she says the pronunciation is actually 'Nano E'
Panasonic kit is generally pretty good. Our Panasonic a/c units have lasted a VERY long time without any "non-user fixable" problems.
I guess another reason for wanting to capture the ozone with the carbon filters, besides people getting a bit weary from the smell is that ozone is very corrosive.
While it's small amounts, if the unit is sitting in a car it'll be surrounded by all manner of plastics and polymer coatings that might start to degrade over time in the immediate vicinity of where the unit is.
I don't know how much effect it might have, but in theory it might which is probably enough for marketing to slap a couple of filters in there.
I had a repurposed corona discharge wire from an old analogue photocopier that was continuously running in a workshop at a pretty high voltage and current (would glow an eery blue in the dark) and after about a year or so when I went to examine it I could see that all nearby iron parts had a fine coat of rust.
Ozone is a real problem for many things, plastic as you say is quite vulnerable and can become brittle with no signs of other damage so adding the ozone filter is a good idea in a closed space like a car.
I think I saw a hint of an 8 hour timer so you could turn it on when you exit the car and it would sanitise it over night and the ozone would not build up.
I wonder if this is what that “Delusional Design” eBay thing with the strangely sturdy welded case was trying to copy. Particularly the blower-type fan mounted upright in the middle reminds me of that. The difference being that this is actually functional.
Those soldered headers really confused me for a minute when I was fixing my onkyo receiver. Board that held the relay/speaker connections had one, whereas other stuff in it had ones that could be unplugged. Tugged at it, wiggled all the usual stuff. Wouldn't come off and then realized it wouldn't and de-soldered it.
The rounded needle is referred to as being a bell, or a bell-end, of you will 😂
Oooo Matron! 🤣👍
I’ve been wondering what the nanoe tech was 👍
18:16 That is the kind of diagram in which physics teacher delight - drawing a van der Graaf generator with small pieces of ali foil spurting off its top. Maths teachers have their equivalent - the saggy boob diagram.
panasonic has room air purifiers with nano e. and a lot of their air cons got that too. i have 5 panasonic aircons with the nano e function and i think they all use the same board for everything hence all that selection option with jumpers.
Nanu, nanu. Mork calling Orson; come in Orson.
I have a question about LEDs. I know this posting isn't about LEDs, but I don't know how else to contact you. In the standard replacement LED bulb for home incandescent bulbs, what makes them flicker. Since they usually have a circuit inside and always some sort of capacitor, does the cap cause the flicker most of the time when it starts to go bad? Wondering...
I have a few LED lamps that failed flickering, they all had one of the LED chips go bad with seemingly an internal thermal related intermittent contact.
I have opened up a couple that had a similar fault with a slowish blinking as soon as they got hot. There is a inline RF choke (plump green resistor looking thing with coloured bands) with a resistor across it that fails open when hot and then the internal capacitor charges slowly via the resistor and then makes a blink. After opening it I could start and stop the flickering by poking the RF choke with a stick to make and break the connection.
After seeing what's inside this, I want one. I can see using this in the home with a different power supply.
Panasonic. Great Japanese company. Still one of the best, even if they are struggling in the mainstream Western markets right now.
Looks (to me) like the "needle" is a tiny globe to produce a much larger corona and therefore, a larger a number of ionised particles flying around. Rather over the top for a car unit.
Very complex little piece of technology! I'm guessing this thing actually does what it says it does. A massive amount of design work went into creating this little device! I researched this a bit and it sounds impressive and was quite a bit cheaper than I expected. Seeing how this thing is built now has me thinking about buying one.
We see a lot of devices out there that make all sorts of claims and when you tear into them, you know the claims are mostly hype. I don't think that is the case here,
Rubycon capacitor in the power supply. Are the other two large electrolytics made by Panasonic?
I doubt it. Only ever seen them use own in industrial products. Consumer grade gets Rubycon and similar Japanese brands, sometimes Chinese caps.
maybe the RF screen is to protect Bluetooth connections from interruption?
Ionisers are notorious for making dust get attracted to grounded surfaces. This would make dust particles attach to the unit instead of your car. I think it is a nice idea. However it is most likely to be there to deduce radio interference from the corona discharge.
With it passing air through it, and the shape reminiscent of certain "personal entertainment devices", you can call this thing a Panasuckit... :P
The 2902S control chip, seems to be a Rohm BA2902S high reliability ground sense opamp.
Thanks Clive. Only you can take a hundred quids worth of complicated tech and reduce it down to just a small willy and a lady garden. 😂😂😂 Brilliant. Cheers 🍺
I like how they use a standard DC jack so you could use it at home with a suitable 12v DC power supply.
WOW😳😱 many electronics to to blow the air.
Thx , great at every time
typical Panasonic - high quality stuff
Serious engineering if you compare some Temu unit.
I'm reminded of that Tom Scot video where he goes to the research lab where they test bear proof bins.
It could be that the discharge head has a nickel-chrome coating. That would make it far more resistant to discharge damage than some finishes.
Had this on the tv infront of my grandparents and panicked when the video first loaded i thaught it was a fleshlit!💀
That Panasonic ionizer is slightly ahead of its time. You could get a large charge from it if you so desired.
I would rather buy a engineered product like this made in Japan, than a cheapo attempt at a clone. Thanks for the video!
I have a question Clive, is an ozone generator the same as a de Ioniser ?
No. Some ozone generators use similar circuitry, but they are very different things. A real ioniser will put out less than natural ambient levels of ozone.
Does this produce the same effect as the carbon fiber bristles on the high voltage modules you’ve shown before?
Theoretically, different, but hard to prove the actual results.
Trust Panasonic to make something complex. But I've looked at their room unit demo, very impressive. They left some things (i remember dog food) in a sealed room with one of their bigger nanoe units, completely odorless room when you went in. Then saw the price, nevermind.
Great teardown of something that did not appear so technical from the outside. The added porn drawing kept my interest.
So, use a sharp point in free space to generate ions, and round point with ring to generate ozone?
I wonder how effective the ionization is
This was a SHARP video
I find it interesting that it was designed to insert in a cup holder in the car. Could that little round electrode be doped with radioactive material?
I tested for radiation and didn't detect any.
There are two wires to one half of the generation component, could this be linked to the high and low settings on out put?
So. When it expires, you have to replace it?
I usually find your videos easy to follow, but this is a pretty complicated device. Is it maybe overengineered a bit? I'm seeing a lot in it that feels somewhat unnecessary.
It's classic Japanese overengineering.
Thanks, quite interesting. Does this mean it's sold as a disposable device? With no easy way to change those carbon thing-a-me-bobs, they will become possibly blocking the airflow over time and so what when they're blocked up... throw away jobby?
I was wondering that about the carbon filters too. Maybe the carbon absorbs ozone for a while (to pass safety limits) before the activated carbon is all used up.
Usually, large particles like dust are first removed with a conventional filter, then activated carbon removes smoke, fumes & other molecules.
If air is filtered through a carbon filter only, I guess dust will eventually clog it up.
@@davadoff Yeah unless the carbon thingees are actually some kind of catalyst. Either way it's going to block up, I guess management realized their little fan wouldn't have had enough guts to pull air through a changeable filter. So they just didn't bother.. Simples !!
I googled Panasonic Nanoe: "The 1800-watt blow dryer uses technology to to infuse moisture-rich ions into hair, helping minimize frizz and enhance hydration and shine." Very odd indeed :)
If seems to me Panasonic mastered emulating transistors with mcus
Had to read that several times before my damaged brain got it right... at first glance I thought you said "emulating transistors with mucus". Obviously, that's snot right 😂😂😂
@@Bloke-in-Stoke bwahaha, your version sounds better
