11-in-1 Air Quality Monitor - Portable Indoor Air Quality Detector with Stand, Real-Time Test for AQI, CO2, PM2.5, PM1.0, PM10, TVOC, HCHO, Particles, Temperature & Humidity with Aler (White-Black)

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).

I just moved to a new home and was concerned about the chemicals of the paint and new furnitures. This air quality monitor gives me peace of mind knowing what I’m breathing in. It shows clear, real-time readings so I can actually see how the air changes in different rooms. The display is easy to read, and setup was fairly easy. It’s also light and portable which I like a lot.

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.

It works the way it's suppose to

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!

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

This air quality monitor is easy to use and gives clear, realtime results. I love how it checks so many things at once like CO2, PM2.5, temperature, and humidity. The screen is bright and easy to read, and the stand makes it convenient to set anywhere in my home. Highly recommend!

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.
