This Shark Air Purifier is a godsend! I live in the Northeast and pollen season is horrible. I also have 2 cats, a dog that sheds year round and a rabbit and a smoker in the house. This Shark purifier has saved me. For the first time in years during shed/pollen season I am not waking up stuffy, puffy or sneezy. I love it! It's relatively unobtrusive, surprisingly quite and easy to use and change filters as needed. Very well worth it.
