I am really enjoying my shark air purifier. First off, its quiet.Ive had many airpurifiers in the past, and none have been this "refined". Next this remote that is built into the unit is very nice for me, as i work at my stand up desk across the room, and love being able to crank it on throughout the day as cars drive by on the gravel road.Also been great so far with pet hair in the air. I feel much better breathing with this next to me all day
