LifeBasis Air Quality Monitor Indoor, 11-in-1 Air Quality Detector with Stand, Real-Time Air Meter Test AQI, PM1.0, PM2.5, PM10, CO2, TVOC, HCHO, Particles, Temperature and Humidity, Dual Alert -Black

It's probably good. Now, it's hard to test something like this well except for temperature, humidity, and CO2. The one test I did manage was during soldering using flux at home (hobbyist level). I had thought VOC would be the one to rise, but it was particulate matter. The readings on this matched the Amazon brand air quality monitor relatively well. So I think accuracy is high. Build quality is fine for standard use. Functionality is sufficient, and it's easy to use. The price is more than fair. As for other air quality concerns (mold, larger particulate matter / dust, etc.), I haven't had a great way to test yet.

This air quality monitor seems pretty accurate and picks up changes in air quality quickly. I moved it from inside to outside to check the difference and the numbers immediately rose. I'm not sure how long the battery lasts, but it comes with a charger. It doesn't seem like a unit that you leave running full-time, but rather one that you turn on whenever you want to check the air. It also has an auto-time off system to shut down after a pre-set amount of time. The kick stand is handy for leaving it set up somewhere, but folds in for handheld use. It has an audible alarm that will sound if the air quality gets too bad (though I haven't been able to test this yet), but you can also turn the volume off

I’ve been using this air quality monitor for a few days, and it’s been incredibly helpful in tracking my indoor air quality. The real-time readings for PM2.5, CO2, and VOCs are accurate, and I appreciate the alerts when levels are high. The display is clear, and the stand makes it easy to place anywhere. It also tracks temperature and humidity, which is a nice bonus. Great device for anyone concerned about air quality at home!

Here are the facts:If the alarm never triggers, simply press ans hold the left button to turn on alarm.CO2 display caps to 5000 ppm.HCHO displays the modulo of actual over 0.150 mg/m3, which means values above 0.150 will wrap back to zero in normal operation until, indicating a false safe until actual concentration drops below 0.150 mg/m3.TVOC displays the modulo of actual over 1.000 mg/m3, which wraps back to zero, indicating a false safe until actual concentration drops below 1.000 mg/m3.Alarm beeps several times before going silent while the red LED continues to blink. If the alarm never triggers, press and hold the left button to turn on alarm.

I started noticing odd smells in my house and coming from my basement and we couldn't figure out whats causing it do i purchased this to ensure its nothing that can harm us and it detects stuff extremely well, i tested it bay sitting it next to my laundry that just came out the wash, somehow washed clothes can make the numbers change from what i learned online so this works extremely well, unfortunately the smell had me extremely worried and was causing me to have bad anxiety and now i feel much better as this verified its nothing dangerous which im very great full for, it alao has a stand sp it can stand up and be seen without issues, also i absolutely love i can take it anywhere in my house to check all over my home.

So this thing shows high levels of carbon dioxide when two other devices I have show none …..I don’t trust it. Being returned ohh and it doesn’t stay charged for more then 24 hours

I purchased this air quality monitor really because I wanted to check the CO2 as well as monitor the humidity and temperature in my home. This unit does much more than that and it’s over my head already. This is something that I’m gonna need to work with so I understand what some of the other readings are, but this one definitely is user-friendly so far. The instructions were not overwhelming very easy to get started. I plugged it in to charge it, and turn the power on, and it gave me an accurate reading right away. Like I said I understand half of the readings. The other half I’m gonna need to do some studying but it does everything I wanted to do at this point if this is something that you’re interested in it’s definitely a user-friendly unit. The price is great. it’s compact easy to put on a wall or on a table top. Go ahead and give it a try. I don’t think you’ll be upset.

I do a lot of 3D printing and I have been concerned with some of the more exotic filaments I use that I may not be getting the filtration I need from my room air filter. This set my mind at ease. I am working on an in-room air ventilation for printing ABS and ASA which really require some air filtration, this will give me some peace of mind that the air purifier is doing a good job.
