I delayed getting this set of filters due to some of the reviews,however I finally tried them.My grown son's room has our litter box in a corner which he keeps very clean and his room has no carpets but the room always had a stale smell.He was always congested and his doctor recommended a hepafitler so I got this set.After 3 hours of running,the air was really fresh and he slept like a dream.The noise is not an issue at all.I LOVE this product & will be buying more for other rooms in my home.

I can't believe how much dirt is being taken out of the air we breath. Get the filters while you can. We have another air purifier and can't get filters for it easily. This time we are getting ahead of the game.

Expensive because you have to change them every two months not every six as advertised.

the hunter air purifiers are great. not only do they help keep the air fresh, it actually has cut down on dusting the furniture

i really like my purifiers i just wished these had the perma filters cuz these are a little more money than i like to spend on just the filters
