Review on Whirlpool WPT80B Activated Anti Bacteria Allergies by Sherri Lee

As far as I can tell, there are no replacement filters for the large model. I carefully measured both the activated carbon and HEPA filters and found none on the market. I would have returned if the return period had not expired. (I should note that I own four other types of air purifiers, including the Whirlpool brand, and have never had a problem finding replacement filters.)
