I have other large air purifiers but this one stands out. It is extremely quiet which is great. You forget it's even on sometimes. The bonus is the heater and fan. A lot of heaters will dry out the air but this one works fast and purifies the air as well. You can set the temp to what ever you like. You just flip a switch to go from air purifier to purified heat or fan. The remote works well and easy to use. I am very happy overall.
