I have year long allergies, and I feel like an air purifier is a MUST in my household. It is easy to set up and super simple to understand. It even has an allergy setting that is really nice. I may be imagining it, but my air felt cleaner and for the few weeks that I've been using it, my allergies have improved. It also has a timer, which is very convenient because you can choose to have it on 24/7, just when you're at home, or you can choose from 3 times how many hours you want it on. My one complaint is that while it is not loud, it is noticeable. Noise level is similar to that of an AC, so kind of annoying, but nothing too loud. The noise is DEFINITELY not a deal breaker though, and because I love this product so much it's getting a much deserved 5 stars from me!
