Works well
These filters fit the small Whirlpool air filtration units (AP150, AP250). I've been running an AP150 near my bed for many years, and I've had noticeably fewer allergy problems as a result. Replacing this filter every 3 months, and the HEPA filter every year, this keeps working, does the job. Amazon has a great price on these (at the time of this review anyway, for $22 & change per 4-pack).
Pre-Filters are part of the technology
The air purifier needs a prefilter and a regular filter. I know the prefilter works because I can see the dust it collects. My purifier runs constantly next to the litter boxes but it takes about 3 months to become completely covered. Mfr recommends changing every 3 months so that works out perfectly.

Glad to have found this good deal, and will be buying again in the near future. Its a pack of 4 quality pre-filters, and the price was right! Fast shipment.
