Very interesting thing. Even in itself as one device is useful. And with a smart house is just gorgeous.

I purchased this instrument to get a handle on the air quality and air exchange frequency at my Medical-Spa. It’s very easy to use and the graphing function gives a clear visual of how CO2 levels are changing over time. Excellent, affordable device.

I use it both indoor and outdoor, and I get fairly consistent results. When compared with readings from purple air the numbers tend to be pretty accurate as well. The device itself while all plastic feels very sturdy as well which was nice!

Baby works well. It is a very practical environmental protection product with novel style, simple operation and complete functions. I recommended this product to my friends. Now the air in many places is not good, so it is necessary to test it. Now health is the first priority.

Verified particulate count with a more expensive meter and this one was pretty close. For the price, you can't beat it! Battery lasts as stated. It's amazing when you put it in other rooms how much the air quality is different. Great product.

So, this was one of the best air quality monitors so far, and we hope you now know what this monitor does and why it's essential for you. Now, without waiting any further, buy this device right away and improve your living and breathing standards. We assure you that in the near future, this one device is going to become a necessity for everyone, so it's better to make a purchase right now!

I'm not sure why I even bought it. It’s simple, easy to use. This helped me decide not to get an air purifier because my Indoor air quality is great according to this thing.

Great legible display from across the room, and very accurate! A lifesaver during the horrible fires, allowed for me to see how effective my Desk Air Monitor was!

I j just bought air purifiers, we wanted some way to test when we should use them and whether it worked. The Desk Air Monitor filled the bill. It's easy to use and set up and gave four different measurements.

I'd been having irritated eyes and was worried about the general air quality. Turns out it was formaldehyde and I discovered it using this Air Monitor. I highly recommend this!
