Review: Super easy to use and very accurate - Super was to use and very accurate.
Review: Excellent monitor! - The monitor was recommended to me by an environmental health professor at the University of Tennessee. It works great, and the instructions are very easy to understand. I have mass cell activation and need to have consistent and reliable readings for my environment. The battery life is very good as it lasts quite a while before needing to be charged. There are no batteries which I like, and charging is easy. The readings are clear and I would suggest reading over the instructions as humidity can cause fluctuations that are inconsistent with correct numbers. I would definitely recommend this product for anyone who has chemical sensitivities or does not want to breathe air that is toxic. We have had some remodeling and it has been a lifesaver, knowing which environments were safe. I highly recommended it!

### ⭐ Sensor failed after 22 months of light use. Do not buy this product.
*by M***J on July 27, 2025*

This product worked really well as an indoor/outdoor air monitor for ~22 months before it lost all accuracy on PM2.5 and PM10, which now consistently reach levels that are 1.5-2x higher than they should be compared to stationary air monitors (PurpleAir, IQAir). The support window for the product is 24 months - which I didn't find out about until I was a week over the window, holding a product that failed several weeks beforehand. I was hoping the inaccuracy was just a temporary issue and the device would self-correct, but it's clear at this point that the sensor won't function correctly anymore so the device is utterly useless for PM2.5 and PM10 measurements. I strongly encourage others to consider another device and do not recommend buying this product (and I wouldn't consider other products from this brand either, as this is a sensor issue - the heart of the product - and that sensor isn't markedly different in this device vs. many others they sell). I've very carefully used, stored, and protected my device for nearly 2 years, and during that time it's been used infrequently during summer months when wildfire smoke is something to be cautious about for outdoor activities. A product that's been so well cared for shouldn't fail outright like this.
