Within the last few years, Kaz, Inc., which owns the Honeywell air purifier brand, has undergone consolidation under a series of owners. "Honeywell" air cleaners have around $400 million in sales worldwide, a top-selling brand. Two results of this popularity are: 1.) Genuine Honeywell Original Equipment Manufacturer (OEM) replacement filters are widely available, and 2.) a brisk aftermarket flourishes, with knockoff-generic filters sometimes represented as "Honeywell." Kaz once used a numbering scheme (i.e. "38002"), for hundreds of different replacement filters, which was easily preempted by aftermarket vendors. Amidst an industry downturn, Honeywells were switched to a modular filter plan which standardized nomenclature and packaging, and reduced the total number of different filters sold. This also made the counterfeits, which still sell well, easier for shoppers to spot. Most genuine Honeywell OEM filters now feature distinctive red/white packaging and the prefix "HRF-" in the model number.

Generics save money, but can have wider variations in quality and multiple revolving-door vendors, than genuine OEM replacements. But, in my opinion, the quality of genuine Honeywell OEM filters and pre-filters has been slipping of late, narrowing the gap with the uppermost Prefilters are a fat cash cow, and Kaz and generic vendors are making the most of the opportunity. offers lower prices, and wider selection including generic alternatives, but also features many third party vendors.

Also called "Filter Type A." HRF-AP1 is a 15.75 by 45.5 inch cut-to-fit carbon-impregnated prefilter sheet for many Honeywell purifiers. , where this prefilter is a top seller, average 4 stars.

The genuine OEM kit has perforations and templates, allowing users to cut out 1 to 8 pre filters, depending on which Honeywell 17000 series owners can get two prefilters, but 50250 folks get only one with about 1/3 waste, cutting the HRF-AP1. Many users find the old prefilter the best template. HRF-K2 reduces odors using potassium permanganate calcite, a bit more expensive than plain activated carbon.
