This should be much cheaper all things considered. I'll be returning it.

Misleading marketing: the product title mentions “particle counter” and one of the pictures includes a “PM2.5 alarm” but in fact that is not one of the air quality parameters that this device actually measures. Returning.

I bought this to monitor the home air quality index and particulate matter in the indoor air, I love monitoring air quality, a must have for home air quality.

Its light weight, easily usable, big screen I love it. I tested it against another monitor I had and it's accurate also.

I love this air quality monitor because it helps me keep my home safe and comfortable. It’s easy to read, and now I know when to open windows or adjust my humidifier.

This is my first air quality tool. It's interesting that have the same CO2 levels on the inside of the house as I do outside. Means I'm doing something right apparently. HCHO and TVOC levels are also well below acceptible levels.Pretty sure I'm going to buy the higher-level unit to monitor PM levels, too.100% recommended.

The temperature it measures is consistently 3 degrees lower than my HVAC display reads, which might just mean it's accurate and the HVAC keeps the temperature in the room within 3 degrees of that number.The measurements for CO2, humidity, and formaldehyde/VOCs seem to also work, as far as I've tested around the house. Charges easily via USB-C (you can leave it plugged in if you really want to, but it doesn't need to be constantly plugged in to function). It's a bit on the thick side (about 1 5/8") for hanging on a wall, but it's got hangers for putting it on a wall somewhere if you haven't got an available flat surface to set it on.
