The Shark air purifier is amazing! I absolutely love it. The remote that is unattachable is very helpful. I also love that it displays the percentage for the air quality. I've noticed on days we fry foods, the percentage drops down to like 90% and slowly goes back up to 100% as the purifier works it magic. I've noticed a huge difference in the air quality in the room the purifier is in and now I want one for every room in my house!
