I have asthma and can really see a difference since we purchased this. I highly recommend you talking with a representative so they can go over your needs and make sure you have the write purified and the right filters. After a week or two I took off the cover & was amazed at the dog hair (2 large German Shepherds) that it collected so we now open weekly and clean it out. I saw some comments regarding a smell. Not sure what that was but I never smelled anything. I also like that it is so quiet, we leave it on 24/7 and you’d never know it was on. Yes I recommend and this is a true 5 star review!
