The app is just okay. Could be much improved. My biggest concern is the price of the replacement filters $22 each! The whole purpose of this is to save money and save the environment by not having so much waste. $199 or a plastic frame and smart sensor with only one filter?So that's like $22 for replacements. Something is not right with this formula. $10 would be the absolute most that these should cost?.

User interface is intuitive and easy to use! Make monitoring and learning about IAQ a breeze. I havent needed to do a filter change yet but I am sure its smooth and seemless.

While not having had any issues, the app is transparent, easy to manage and provides the information needed to feel good about this new system.
