This Shark Air Purifier is very powerful despite its smaller size. It works pretty quickly to clean the air in our kitchen after using the air fryer. It is very quiet and I don't notice when it's on. The directions for setting it up were easy to follow and I had it running out of the box in less than five minutes. It says it's for rooms up to 1,000 square feet which is a large amount of space, especially in my smaller home. This clears the air of allergens, dust and dander which really helps with allergies as well within our older home. I really like this product and highly recommend it!
