    I enjoy that is able to connect to mobile however it is limited a this model does not allow you to change the temperature settings from your mobile device. I have noticed you can work around that by setting a scheduled routine on Alexa. Over all its an amazing product and I'm 8 months into use before being my first filter replacement.

    Great device! Note for advance users. The heat mode does not work remotely. It must be adjusted on the remote next to the machine. Everything else is available through the App for remote access EXCEPT the heat mode. Not a deal breaker but I think it would be better to know in advance.

    Great product and no regrets! I've owned for about a year, and it's worked as expected. My favorite thing about this air purifier relative to a Honeywell HEPA filter that I own is that I can set this to auto and forget about it. The unit will monitor air quality and temperature modifying fan speed as needed. I'm here after owning for one year, because I'm purchasing a second one for another room!
