"Why is this product priced at over double the retail price from whirlpool?" 2009-04-15
By Gaiamuse (West Tisbury, MA)
At over $60.00 this product costs more than double the price for which you can get it from Whirlpool directly...don't understand why. Is there something special about it?

"Third Party replacement pack" 2008-09-07
By Alexandra Higgins (Palo Alto, CA United States)
This is a third party pre-filter replacement pack. The slots are not an exact fit for the Whirlpool Whispure 510 Air Purifier (AP510) but you force it in. Functionality is just seems fine.
