Fantastic product! From its quality to its clear display and crisp calculations, everything is well-designed. It’s also easy to turn on and install.We live in an area where opening windows can be challenging due to the weather. As a result, CO2 levels can rise, and this monitor displays the counts nicely.As soon as the CO2 monitor detected an increase in oxygen, it recalculated and displayed the updated numbers accuratelY

We needed something in the house to help us monitor the temperature, CO2, and humidity. I came across this product that gave us that plus more. 7 different monitoring tools, plus the time and date, and an alarm for high levels!It is rechargeable or you can leave it plugged in- but the energy saving mode is great so it doesn't kill the battery quickly. I find it really easy to read and very durable. Overall a great value for the money with all of the functions. Very happy with my purchase.

I recently purchased this air quality monitor, and it has exceeded my expectations. The setup was quick and easy, and the device provides accurate real-time readings. The display is clear, and I appreciate the multiple indicators for PM2.5, CO2, and VOC levels. It helps me ensure that my home environment is safe, especially for my family. The battery life is impressive, lasting several days on a single charge. I also like the mobile app integration, which allows me to track air quality trends over time. Overall, this monitor is a great investment for anyone concerned about indoor air quality. I highly recommend it!

I do a lot of 3d printing and was curious if the room where the printer was located was warm enough and if humidity was effecting my prints. I found that this device measured VOCS as well so I was interested. I like that it's portable and rechargeable but usually leave it plugged in. The display is bright and easy to read. I took it work to test it against calibrated air quality monitoring equipment and the results were spot on.

Update:Dropped this to 1 star from 5.Now that the weather has been nicer, we can open doors and windows to get some fresh air.Now every time we close things up, the CO2 levels go insanely high and after1500 the meter beeps.TVOC's also went up tenfold.This has happened pretty much every day, but today was cooler, and worse than usual.This thing shot up to over 2400!Not sure it can be trusted. What a shame, as it had potential.We ordered one for someone else and they are seeing similar issues at their home as well now with the cooler weather.Original review:Wasn't sure how well this would really worked, but it seemed like it should do a decent job.Got it a week ago, followed the directions to let it sit for a bit, then took it outside for the 2 minute calibration with outdoor air.Brought it in, and overall it averages between 450-460.Seeing as the picture on the box and listing shows 450, I wasn't convinced this was doing much. Well yet anyway, till it got put to the test.Now it includes a USB-C power cord, but no adapter, so you'll need your own to charge it.I decided to leave it plugged in, so no worries about plugging it in every so often to charge it back up. So far it has been fine.After 20 minutes or so, it kicks into a power save mode, where most of the screen goes off, except for the clock and the colored LED bar, that indicates C02 levels. The instructions explain the ranges.They also show to press the power and - button together, to shut that off. Tried that a few times but 20 minutes later, it kicked off again. Press and held them for a couple of seconds, got some beeps, and the screen has stayed on since.The LED's do seem to bleed over a bit, regardless of brightness setting, so it is actually easier to read a couple of feet away.Now here's the cool part about this. As I said, it averages mid 450's or so most of the time. I've seen it dip as low as 430 and up to about 520.It sits in the living room.We decided to make some bread yesterday, and after about 10 minutes in the oven, noticed this thing started climbing on the C02 levels. Went to 600, 650 up to over 850.Took me a minute to realize, it's managing to pickup the C02 coming off the bread due to the yeast in it.When the timer went off and we opened the oven door, this thing climbed to around 960.Between the AC moving air around the house and such, over the next hour it slowly crept back down to our average range.So yeah, that convinced me this actually does work.If things change, I'll update this review.
