Honeywell Allergen Remover Replacement HEPA Filter for Honeywell HEPA Tower Air Purifiers help to capture 99.97% of microscopic allergens such as mold spores, pollen, dust, smoke, and pet dander as small as 0.3 microns.
I use this filter with the HEPA 050 air tower. I live in a basement apartment with a lot of cobwebs and mildew. I find this filter really makes a difference in making the air more breathable. After I leave it running for a day or so the air feels much fresher. The filters last for around 6 months, so you get pretty good value for your money. Recommended.
