Customer Reviews For The Honeywell True HEPA Replacement Filter O

Yes, the Honeywell Store only sells Certified Honeywell Filters.

The Honeywell Filter O is designed exclusively for the Honeywell HPA120 and HPA125 Allergen Plus Tabletop Air Purifier series. Using this specific 3-in-1 filter ensures that these tabletop models maintain their certified HEPA performance and internal air pressure.

Unlike standard filters that may only target one type of pollutant, the HRF-O1 combines three layers of protection into a single unit:

• Vacuumable Pre-Filter: Captures larger particles like dust and pet hair.
• True HEPA Filter: Traps 99.97% of microscopic allergens (0.3 microns) such as pollen and smoke.
• Activated Carbon Layer: Reduces common household odors and Volatile Organic Compounds (VOCs) from cleaning products and pets.

To keep your air purifier running efficiently, it is recommended to replace the filter every 9 to 12 months. The exact timing depends on your air quality and how frequently the unit is used. Replacing it on schedule helps protect the motor and ensures the air remains noticeably fresher.

Yes, it can. Certified Honeywell filters are specifically engineered for a precise fit within the HPA120/125 housing. Using generic or "compatible" brands may lead to air leakage around the edges (bypassing the filter), reduced motor efficiency, and could potentially void your air purifier's warranty.
