I bought this a few months ago looking for a good purifier for my room. I have allergies to dust and did a bunch of research watching reviews and reading on other users feedback. Is is packed with every feature available, no. Does it do what 99% of the people need it to do yes!  I tried the heat setting one night and it worked to take the chill out of the air. This is by no means a heater or designed to be a heater. One of the features I like is you can set days and times for it to turn on and off automatically. I find this very useful as I have it off when I am not home and turn on about and hour before leave work. This way when I do get home it has already been running to take a majority of the junk in her air out. It will adjust the fan speed automatically by how much particulate is in the air which is nice. 



Only drawback that I had was the WiFi drops here and there and is a pain to reconnect. Otherwise we’ll

Worth the money if you want a one and done purification for a room.
