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-White)

Just moved into a new home with some strong smells, so I got this to monitor the air. It’s surprisingly sensitive — blowing on it spikes the CO2, and it beeps during heavy kitchen smoke when cooking. Turning on the air purifier clearly lowers the PM2.5 and PM10 levels. I also used it to check our new furniture — luckily, HCHO levels were normal. The screen is clear, the device is lightweight, and the stand makes it easy to place anywhere. Great tool for peace of mind in a new house!

I gave this thing a good test before reviewing, 5 months. I've never had an air quality monitor so I wasn't sure - 1. what to expect and 2. if it really worked like advertised. I live in a older home and have a dog and just had concerns about air quality in general in my house. I live in Florida so the pollution aspect is not really applicable to my experience...however if you live in an area with noticeable pollution and have concerns about that daily....GET THIS! I calibrated this unit outdoors and then went inside my home and ran the various tests. I was relieved to find that, for the most part, my air quality is fine. It's interesting to watch what happens to it when you cook or do other things in the home that put things into the air (i.e. burning candles, etc)... it picks up all of it. I was able to determine that one area of my house had worse quality than others, so upon further inspection I found an area that was significantly dusty and had been missed by our cleaning people multiple times. Win! It's easy to read and use, seems to be accurate as I can see the fluctuations between rooms, indoors or outdoors, and if theres carcinogens in the air from cooking, etc. I removed one star because the instructions weren't great and I had to do some research about the different setting and what it was measuring.

We live in an area where the quality of our air has been questionable over the years. It is something that worries and concerns me very often. Having this monitor makes me feel so much better and gives me peace of mind that my family is breathing clean air. It is easy to use, easy to understand. It functions as it should, I do recommend thoroughly reading the instructions but it is good value for the money. For the peace of mind. It gives. Good product

I like the display and the data it gives. The problem is the battery life is horrible and it shuts itself off even if I leave it plugged in.

Only goes off when we cook. Had a lot of mold in the room and it didn’t detect it. It was cheap though.

Easy to use, provides good information with and easy to read display.

This air quality monitor helped me a lot. I have been having running nose since April, after trying everything, it didn't work out for me. So I bought this monitor to check the air quality in my house. The numbers are definitely abnormal and I will find professionals to clear my house properly. Definitely worth the money!

I already have an air quality monitor, it works great, but I want to get another one for my basement, so I chose this different one. And when compared with the one I own, both have similar readings, so I know the accuracy is correct. I feel peaceful when I know that the air surrounding me is under monitoring.
