We have been having this Shark Air Purifier MAX 3-in-1 with True HEPA Filter for about a month now and absolutely love it! You can definitely tell the difference in the air quality. It truly smells fresher. I really like how it removes smells from the air, especially while cooking. I have also found that my house isn’t as dusty since I’ve been using this air purifier. Set up was easy right out of the box and it’s easy to use.
