Over the last 7 years genuine Whirlpool Air Purifiers and Replacement Filters have been manufactured by a company that has recently stopped using the Whirlpool name. The very same filters are still in production – the only change is that they no longer carry the Whirlpool name and as a result can no longer be called “genuine”. This 4 pack of pre-filters was formerly known as the Genuine Whirlpool 8171433K Carbon Pre-Filter 4pk and without the Whirlpool name it is now available at a lower price.
Whirlpool Air Purifiers: AP150, AP15030, AP15030HO, AP250, AP25030K, APR25130L and APR25530L.
