LifeBasis Air Quality Monitor 10-in-1 CO2 Monitor Rechargeable with Stand Real-Time AQI,PM1.0,PM2.5,PM10,TVOC,HCHO,Particles,Temp and Humidity Air Quality Detector Indoor for Home Office School

It work very well , I use it in truck fot monitoring air. reccomend .

Fantastic machine for the price. Would have like a little more description in the manual to tell you what all the figures meant.. but google works just as well!

Very sensitive, clear and easy to use. Easy to power from the USB cable or runs on battery for a decent length of time. Definitely lets you know when it's time to open a window!

We bought this to check for any toxins in the air whilst builders where in to rebuild our bathroom. Sadly a lot of times we found the builders to be using high VOC materials, so we used this to check when the air quality in the house was good enough for my then pregnant wife and now our newborn, to come back into the house. Not only will it detect particles an VOCs, we also used it to check the off gassing (of formaldehyde) from wood (furniture and building material). It's amazing to see there's still quite some formaldehyde present in ply boards from your favourite DIY store... We've not experienced any issues with accuracy (CO2 etc.), however the battery life is not very long. So we usually keep it charging (USB-C 👍🏻)

Battery life could be better I think it only lasts for 24 to 48 hours and needs to be charged again. Clear display and works very well. Size is ok as well. Happy with the purchase.

The item did not work, hence the 1-star, however I would rate the vendor 5-stars. Prompt customer service with good solutions to the problem provided.

I presume that it is accurate - I have no way to test it but..... The battery life is horrendous! It doesn't last the night. It also has no ability to store a 'history' of readings so no trend can be reviewed - it is a 'point-in-time' reading only.

Best, good battery life and never let me down.

The temp and humidity were on par with others I have in my home. The CO2 monitor seemed to work well. I tried it in different locations and received the readings I thought I should be getting. I open doors and windows each morning to let fresh air in and use this device to know when to close them back up as my reading are around 950 in the morning when I get up, and after opening windows and doors in the morning it goes down to about 450-500. It's very easy to use. Just be sure in the beginning to take it outside and let it run 30 minutes, then do the CO2 calibration and that's it. I would say for the price, it is as good as it gets. I do analysis paralysis before I buy something, and this one is doing the job for me. Also the PM monitors are on point too as when I run my air purifiers, you can see the values decrease.

I had a serious problem with clogged sinuses, head aches and general breathing issues. I suspected CO2 buildup in my house, but could not narrow the problem down. I decided to try this air quality tester out. I put it in every area of the house, checking the sewer, gas stove, fireplace, all my room, furnace. I got CO2 reading above 1000 for the most part, and moderate level dust readings. That night with the house all closed up the furnace came on and there was a serious spiked in particle readings. Although i had changed my furnace filters on a regular basis, i did not thing the problem was dust in my vents. This meter solved my problem in one night. DIRTY VENTS. I cant tell you the exact accuracy of this meter, but it does seem pretty good. The battery charge lasts about 24 hours, but the charger can be plugged in at all times. I like the display and color coding on the readings to show each condition level (good, moderate, bad). The response time is gradual, but starts within seconds of any changes. The audible alarm is nice. The TVOC feature is really good and detects gas from my Natural gas leaks. It was a learning experience to understand air quality in the house, that i would recommend for anyone.

I wanted a portable air quality monitor, especially one that I can carry around. While most air quality monitors are relatively portable, they are generally not shaped in a way that allows you to carry it in your pockets without bulging out. This one, on the other hand, is relatively flat, and fits into a pants pocket with relative ease. One concern I did have with many of these air quality monitors are whether the sensors provide real numbers based on real sensors, or if they infer other values based on a single sensor (usually TVOC or organics based, since that's usually the cheapest sensor available). On this detector, placing it near an ammonia solution only includes the TVOC values, and not PM2.5 or CO2, which is expected. On a low-quality sensor, typically the ammonia solution would significantly spike the CO2 readings. Putting the sensor next to water vapor only increases the PM2.5 and humidity reading but not TVOC or CO2. This is also the expected reading from a detector that has actual sensors built-in to detect these variations. The PM2.5 values also match up with my other portable and PurpleAir sensors installed outside. I also like the fact that this detector has a way to do CO2 calibrations, which is something that most detectors try to do on an automatic basis or not at all (this makes the reading somewhat inaccurate for those sensors if the sensor is inside a stuffy room constantly). The ability to calibrate manually is not something I usually see, so this is definitely a good addition. Considering the fact that most detectors that have real CO2 sensors generally cost close to $100 or more, this is actually a decent detector that is decently priced and provides good values. While you won't be able to monitor the values online since it has no data export or Wi-Fi/BT capabilities, it does make a good travel sensor that you can carry around.

Good device, the only thing I would add is that it measures carbon monoxide.

I’m amazed and surprised at how well this works. We had to move during our pregnancy and trying to test the VOC levels at the new apartment/homes to make sure it’s safe for our newborn. Despite the price, it works like a charm compared to other more expensive brand. The battery holds its life pretty well, instructions are very easy to follow. The most important thing is that it works!!! VOC levels will immediately increase if it’s brought into a room with fresh paint/smell of paint and will decrease as soon as it’s brought to the window area with good ventilation. Very amazed at the product and highly recommend for anyone that’s concerned about their VOC levels/air quality at home
