Works well.

Very pleased does what it says on the box

Myeverywhere. Dad has breathing issues recently. Need to minitor thw air around him and took a chance on this. Well we had to return the 1st one...b/c it was defective feom factory and would not stay powered on. Tried everything. Just bad luck I guess b/c the 2nd one works perfectly and we use it evrywhere every day

I like this air quality monitor! It measures multiple metrics (AQI, CO2, PM2.5/10, HCHO, TVOC, temperature, and humidity) and the display is bright and readable. I bought it to keep tabs on VOCs from my 3d printer. I'm happy to be able to verify that the printer's filter is working. I compared the readings with the air from my Coway air purifier, and as expected the purifier was working to keep the air I breathe clean. It's very portable with a built-in kickstand, though the battery life isn't great (it'll have to be charged every day if you don't keep it plugged in).

It's 2025 and Covid is still happening. Everywhere I go, I've been testing the air quality. You'd be surprised to know the Y is pretty clean. But the used bookstore needs to open a window. My house when I cook also is not good. My car went first getting into it. This thing will let me know how musty the air is. I love getting the heck out of town when I know the air is not good enough for me.

I'm so glad I bought this. I knew there was something going on in my house because I was having a lot of sinus issues, but I couldn't pinpoint it. When I stayed away from my house, the issues disappeared so I knew it had to be home. Immediately after I got it and turned it on, this monitor picked up a problem. It was so easy to read and right on the money when it came to accuracy. It will be staying in my house from now on!

Very durable and accurate machine. The battery life is very good. I grab this little machine to measure air quality in the house and it also measure the humidity as well as other features.

Awesome device very sensitive. Biggest complaint is the battery life. On a full charge it dies less than 24 hours.

No brand name anywhere, on box or device or on manual. Showing zero values of pm.

Using this product for last 15 days and it is working fine, showing the correct AQI numbers.

This gives accurate aqi data with Co2 Nice product

Faulty product. Worked for a month and then stopped working. Since it crossed the return window, Amazon declined any help and did not provide any sort of help when I expected them to replace or repair the product. Amazon customer service is soo poor they did not even let me share my concern and just shut the chat window by saying the usual sorry. Do not buy this product from Amazon.
