Replacement PRE-Filters for Honeywell Air Purifiers 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.
