I've been using this air purifier in my children's room for a while now. It is super easy to use and really quiet. I keep the door closed, since the air purifier is on, and I am still able to hear them. That is nice. It has a timer which is also wonderful.  I set it to 8 hours and do not have to worry about turning it off in the morning. My house runs on the google system and this device is only compatible with Alexa, so that's not ideal. What is ideal is that it is really simple to clean and change the filter. The filter twists right out the bottom and the new one twists right back in.
