This shark purifier is just what I needed.  I have two small dogs.  It was really easy to setup and I wasn’t that shocked when my air quality was in the red instantly when I first started it.  All you have to do is put it on auto and it does the work.  It’s actually really quiet that I sometimes double check to see if its still on.  I have it in my living room and I definitely can see a decrease in my coughing and sneezing. I love that the small size of the purifier covers a large space.  Shark is a quality brand and I would definitely recommend.
