Great For Small Rooms

This is my first air purifier, and i really like it. I have had mine for about 4 months. It does a reasonable job in the main part of our small apt on the medium setting, but works best in the smaller room. Breathing is much easier in all rooms I use it in, but I am looking for a slightly larger unit for the larger area.

How effective is the HPA120 at removing allergens?

The Honeywell HPA120 is a high efficiency particulate air (HEPA) air purifier, which means it can remove up to 99.97% of airborne particles 0.3 microns and larger. This includes dust, pollen, pet dander, and mold spores. The portable air purifier also has an activated carbon pre-filter that helps remove odors and VOCs.

How big of a room can the Honeywell HPA120 clean?

The Honeywell HPA120 is rated to clean rooms up to 110 square feet. This makes it a small room air purifier. However, the actual size of the room that the HPA120 can clean will depend on the level of air pollution in the room.

How often do I need to change the hepa filter on the Honeywell HPA120?

The Honeywell HPA120 comes with a 3-in-1 HEPA filter. The HEPA filter should be replaced every 9-12 months. The actual replacement schedule will depend on the level of air pollution in the room.

What filters do I need for the HPA120?

The HPA120 uses Replacement True HEPA Filter O.

My air purifier is starting to make noise and the air output is less. What’s wrong?

The filter may be dirty. High amounts of particles can block the pores in the filter and stop the air from moving through it. Replace the Filter. The HEPA Filter should be replaced every 9-12 months. To ensure the unit continues to perform properly, replace with Certified Honeywell Filters.

3-in-1 O Certified HEPA Filter

Filtration begins at the first level with a vacuumable Pre-Filter designed to capture larger airborne particles. Next, the certified HEPA Filter acts as the second level, capturing up to 99.97% of microscopic airborne allergens and particles, including dust, pollen, pet dander, dust mite debris, and smoke as small as 0.3 microns or larger, from the air that passes through. Finally, the third level uses an Activated Carbon Filter for effective odor reduction, ensuring the released air is clean and fresh. For optimal cleaning performance, replace your HEPA filter every 12 months. The filter check/reset light on the HPA120 Air Cleaner will remind you when it's time to change your filter.
