Customer Reviews

Well designed, affordable air quality monitor!
2025-12-14T05:29:42.238Z

I've been searching for an affordable air quality monitor for awhile now - they're all cheap junk or too expensive. This Amazon one is amazing - takes the best feature of higher end monitors and takes it to an affordable price point. The app is good, and I like the air quality light feature (which allows you to turn it off and it will only turn on to red when low quality). Super well designed and thought out. It does require to be plugged in so there is no battery option, but I've been able to connect to it with no issues and don't have to worry about swapping batteries. Also can be accessed remotely, not like some monitors that are Bluetooth range only or require some crazy subscription. Sensor is accurate and fluctuates correctly based on surroundings!

It really works well AND allows for triggering routines.

It works very well and is insanely easy to set up. So far as I've been able to find, it's the only sensor that can trigger a routine based on temperature (or other environmental factors) without involving IFTTT or a Zigby device with a hub. Yes, it's more expensive than most but it just WORKS and that makes me happy.
