I’ve never had an air purifier, so I was a little intimidated at first. Luckily, the screen is very easy to understand with the help of the manual. The actual purifier is much quieter than I thought. Of course you will hear it at the highest fan setting but it’s not very loud and intrusive. Luckily we haven’t had much wildfire smoke recently so I can’t say how it does with that, but I do think that it helps with my wife’s allergies. She doesn’t wake up with a runny nose anymore!
