How effective is this air purifier at removing allergens?
This 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 this Honeywell Air Purifier clean?
This air purifier is rated to clean rooms up to 155 square feet. This makes it a medium room air purifier. However, the actual size of the room that the HPA104WMP can clean will depend on the level of air pollution in the room.
How loud is this air purifier?
This air purifier has four fan speeds, and the noise levels vary depending on the speed. At the lowest speed, this home air purifier is about as quiet as a whisper. At the highest speed, the portable air purifier is about as loud as a normal conversation.
How often do I need to change the filters on my air purifier?
This home air purifier comes with a pre-filter and a HEPA filter. The pre-filter should be replaced every 1-3 months, and the HEPA filter should be replaced every 6-12 months. The actual replacement schedule will depend on the level of air pollution in the room.
What filters do I need for this air purifier?
This portable air purifier uses Replacement True HEPA Filter R and Replacement Pre-filter A.
How do I reset my Check Filter or Check Pre-filter light?
After you change your filter, the "Check Filter or "Check Pre-Filter" light will remain on until it is reset. With the air purifier powered on, press the lighted button, and hold for approximately 2 seconds until the light turns off. The electronic filter check is now reset.
My Air Purifier is starting to make noise and the air output is less. What's wrong?
The filters may be dirty. High amounts of contaminants can block the pores in the filter and stop the air from moving through it. Replace the Filters. The HEPA Filters should be replaced every year and the Pre-Filter and Enhanced Odor and VOC Filters should be replaced every 3 months. Please note these are guidelines only and filters should be checked periodically as individual home conditions may vary. To ensure the unit is performing properly, replace with Certified Genuine Honeywell Filters.
How long should I run my Air Purifier?
In general, the unit will be most effective when doors and windows are closed. It is recommended that you run your air purifier while you are at home to help clean the air. If desired or conditions warrant, you may run your air purifier 24 hours a day
Can I wash any of the filters in my Air Purifier?
No. Washing the filters in your air purifier will ruin them.
What are VOCs?
Volatile Organic Compounds (VOCs) are emitted from various solids and liquids such as paints, cleaning supplies, building materials, and permanent markers. Some of these compounds can have adverse short and long term health effects and consistently have higher concentrations indoors than outside.
Do Honeywell Air Purifiers Emit Ozone?
No, Honeywell HEPA Air Purifiers use HEPA Filtration that does not release ozone into the surrounding area.

Honeywell Air Purifiers Are Tops!

I purchased my first Honeywell Air Purifier approximately 20 years ago. It is still with me today...although it looks dated, it is a work horse!!! Have bought two more recently...quite attractive...and they are fantastic! Strong and effective, quiet, easy filter changes, and any lights can be turned off with the touch of a button. This no light feature is great for light sensitive sleepers. I continue to be sold on Honeywell!

I have been using Honeywell air filters in my home since 1990. I let them run 24 hours/day, and they keep my air fresh and clean and removes pollen, pet dander and smells. Love it!!

works well

Put it in my young daughter's room to hopefully help with allergies, and it seems to be working well. It's not too loud basically serves like a white noise machine.
