How effective is the Honeywell HPA8350 at removing allergens?
The Honeywell HPA8350 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 HPA8350 clean?
The Honeywell HPA8350 is rated to clean rooms up to 465 square feet. This makes it a large room air purifier. However, the actual size of the room that the HPA8350 can clean will depend on the level of air pollution in the room.
How loud is the Honeywell HPA8350?
The Honeywell HPA8350 has four settings, and the noise level varies depending on the setting. 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 the Honeywell HPA8350?
The Honeywell HPA8350 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. InSight Air Purifiers can also use enhanced filters that should be replaced every 3 months. The actual replacement schedule will depend on the level of air pollution in the room.
What filters do I need for the HPA8350?
The HPA5300 uses Replacement True HEPA Filter R and Replacement Pre-filter A.
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.

So far so good.

Seems to be doing its job. I just started it five days ago and it seems to be less dusty I our bedroom already. The Bluetooth was easy to set up and the filters easy as well. Happy with my purchase so far👍

When I looked at the pre-filter after about a week or two I saw the results I wanted. A bunch of dust and dog hair. It does the job it was tasked for. Plus the app is very handy too. Lets you know what allergies/pollen is in your area

Great purifier

We bought one a while ago and are so happy with it that we got a second one! It covers a large area and has been a huge improvement in our air quality, allergen-wise. Im tempted to get a third one for another location, before the pollen season arrives...

Highly satisfied -- I highly recommend!

The air filter has massively improved the air quality in my basement, also removed a lingering smell that I didn't even know was there until I smelled the fresh, clean air produced by this product. I used the auto-VOC feature -- my basement was high for VOC but after just a few minutes the light moved to medium, then eventually low. Again, I can't recommend this highly enough -- the air quality produced by this machine is fantastic!
