pro tip : watch movies on Flixzone. Me and my gf have been using them for watching loads of movies lately.

[@Skipperj]

I got one and found our vacuum cleaner which says HEPA Filtration, s far from it. WE bought a water Filtrating vac which has zero dust in it's exhaust stream. Much better air quality and meter is mostly in the green.

[@EmM-ko7mu]

apparently the oil we put in the humidifier that should have been good for our health was giving off super high levels of TVOC and HCVO. Our readings were TVOC 5.00 HCVO 1.00

[@electronicsNmore]

Oregano oil? I've used that.

[@lenajackson5448]

Allergy issues aside, I would like to see an air quality monitor/VOC meter used in a plant nursery. The recent claim is plants don't clean the air well but I suspect in a small room with 100 plants, your meter is going to show lower VOCs than other rooms of the same construction.

[@heresteven]

I bought one and I use it at work to check the air quality. It is good at checking how much dust I generate with different activities like walking, or sweeping, or when a truck passes by. Dust can do severe damage to the lungs.

[@rooternook]

[@DougHanson2769]

Isn’t there a smartphone app for Indoor Air Quality, from like 0.001 to basically severe pollution >500 or whatever. As well as magnifying lenses via another app for pics to see ie., dust mites Fleas and other things that could be very harmful to people and pets? It’s August 2023 and technology is supposedly fantastic but the many manufacturers are getting much better basically each day. And it can be expensive.????? If anyone knows what it is called and and how to find and use it without spending too much money etc. Let me know if there’s really such a thing and the MSRP $$ etc. Please let me know. Thanks

[@billycasper3351]

I want to appreciate your review process and approach. It's thorough, complete and flawless. Thanks a lot for the guidance. I just wanna know if there are better sensors in the market !?

[@electronicsNmore]

Yes. There are more accurate units, of course they're priced higher. Thanks for watching!

[@2711marcus]

Looks accurate for PM2.5 not sure how accurate it is for PM1.0. It is the ultrafine particles that do the most harm. I think to accurately measure these fine particles you would need very sophisticated equipment costing 4 figure sums 🙈

[@mrlocophone]

Nice video! I have a question, wouldn't it be enough to just maintain a nice cleaning and ventilation routine to keep the air quality on a nice level? In that case people wouldn't need to buy an air quality monitor?

[@electronicsNmore]

Keeping clean will keep dust levels way down, but you still won't know about the VOC's in the air.

[@ian1204]

Buyer beware. If you order 3 of these things each one will tell you something different. The first one told me my air was dangerous. Second one said it was perfect. Third one said right in the middle. All sitting next to each other. I'm not the only one if you do some digging it's a known issue. If you have no verifiable baseline reading you have no idea if this thing is accurate. It's a very dangerous to assume it is correct if it reads low, and very expensive if a false high reading gets you tearing your house apart and trying to solve a problem that isn't there. Definitely not a proven device without something to compare results to.

[@electronicsNmore]

Sounds like they weren't properly calibrated. They're not going to give you super high accuracy results like a unit costing several hundred dollars or more.

[@elo7269]

Howdy. I just got a quote to do an indoor air quality test. They said it would be $595. I literally live right by a major freeway. I also just got a whole house fan. I want to test the air before I start opening windows to let a cool breeze in. I clicked on the link to this monitor and it says page not found. I don’t know how much this is. Should I just do the $595 or do it on my own and purchase a device?

[@learrus]

Great break down. Just ordered one thanks to you and a couple other vids showing the Chinese models are garbage and to sink some cash in. Found one for a few bucks cheaper on ebay by sheer luck

[@MrArcticPOWER]

So I purchased this unit from your link a few weeks ago because I've had some health issues just like you described at the beginning. Turns out I have very high reading (HCHO 0.9 and TVOC over 6.0). Do you have an idea what should I do from there?

[@Outside-In.]

I have the TemTop m2000 and it is awesome, a bit more money but when it is a matter of life or death - I think we may need to spend a little more to not get a fake LOL. I see so many fake meters with only one sensor inside to give 6 or 7 different readings and that is just not possible, so many people are buying them thinking that the information is keeping them safe while all along the information is faked by mathematical equations performed by a micro-processor instead of genuine sensors. Hope this helps. You may also want to look at the TemTop M10 - it is a bit less expensive and is still up to the TemTop high standards of quality. I am getting ready to create a video about fake and legitimate meters and am looking forward to hopefully saving someones life from buying a fake meter.

[@EVMYT]

Could i use this to test the efficiency of the hepa filters my home air purifier or in my car HVAC filter?

[@bacaw2856]

The only drawback to this chinese-made, noname gizmo is the fact that it doesn't measure what it says it does. The formaldehyde measurement is calculated to be approx 1/7 of the TVOC and the temperature sensor on this thing constantly reads way off. You can get better and cheaper machines that will measure TVOC for you much more reliably, and should you want one that can do HCOH and particulates as well, just be prepared to invest a lot more.

[@electronicsNmore]

For the price is does a decent job. If you want super sensitive and high accuracy, you'll need to spend at least hundreds more. Thank for watching!

[@editthlh]

Can I use the sensor directly? I mean, trying to connect it with a tube to measure how the formaldehyde concentration is low inside a box?

[@Michaelc-gn3eg]

Could you try and review one of these from Amazon . I’m having a hard time finding a really good one on Amazon

[@CCult-iw4xk]

Do you know what I should do to calibrate it? The mine always puts 0.000 in HCHO and 0.000 in TVOC. It only measures PM 2.5, 1.0 and 10

[@electronicsNmore]

Something isn't right. The values should be fluctuating as you move into different areas.

[@publicmail2]

The 2.5 micron particulate works by laser scatter like a photelectric smoke detector works, not but what gets in between the laser and detector plate.

[@electronicsNmore]

Particle measurements are based on the fact that when a particle passes through a beam of light, some of the light is scattered. The detection of scattered light caused by the particle in the air is recorded on the photo or light detector sensor plate. Unfortunately I may not explain everything perfectly in my over 600 videos. How come you have a habit of being a pedant on my channel? Just curious. You're the only one that stands out.

[@Sw33tBoy88]

Hello, I bought this device on your recomandation but I don’t know how to turn off the beep because it’s annoying when I push it and the values increase.

[@Geedygeedy]

Some people should just live in a Bubble. Modern Housing is pretty much the same. Your in a Sealed Chamber breathing in your own creations. I live in a home that breaths. This unit really does little to locate the issue it would seem ? Not so good at Identifying what it is being measured ? How do you correct the issue at hand not knowing what is being Measured ? Just Asking. Only real way to go about Identifying the offending material would be a Spectrometer. Rather Pricey Tech Toys.

[@electronicsNmore]

The device helps you to locate the source of high dust, formaldehyde, and VOC's. The closer you get to the source, the higher the reading. Once the source has been identified, you eliminate it. $49.99 isn't expensive. Thanks for watching!

Mine was fine when first got it had almost perfect readings but 2 days after that it just stays stuck on 1.9999 HCHO and 9.999 TVOC 😟.

Every place else in my building gets a lower reading. Even the smoky hallway and outside of the apt where the smoker smokes. Could it be a glitch or is my place really off the scale toxic?
