Sharks Air Purifier Max works extremely well at cleaning the air. It’s very quiet and performs well. I can definitely tell the difference since using this product. Set up was extremely easy. The different modes are useful and I like that with a push of a button you can see how many viruses and pollens are in the air. Very happy with this product. My son has allergies, it makes me feel at ease knowing this is cleaning the air for him. I’ve noticed a big difference. Very light weight to move upstairs and downstairs when needed. Definitely recommend!!
