Visual filter check reminders and an automatic shut off timer have also been included to ensure that the Honeywell HPA100 is operating as efficiently as possible.

A+ Genuine Pre-Filter

This portable air purifier works with the Honeywell A and A+ Pre-Filter. The Pre-Filter is the first level of filtration and helps capture large particles such as dust, lint, fibers and pet fur and helps to reduce VOCs & odors from cooking, smoke, bathrooms and pets. This filter should be replaced every 3 months. The filter check/reset light will remind you when it's time to change your filter. Initial filter is included. To ensure stated product performance, use only genuine and certified Honeywell replacement filters.

For optimal cleaning performance, replace your HEPA filter every 12 months. The filter check/reset light on the HPA100 Air Purifier will remind you when it's time to change your filter. Initial filter is included.

How effective is the HPA100 at removing allergens?
The Honeywell HPA100 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 HPA100 clean?
The Honeywell HPA100 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 HPA100 can clean will depend on the level of air pollution in the room.
How loud is the Honeywell HPA100?
The Honeywell HPA100 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 the Honeywell HPA100?
The Honeywell HPA100 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 the HPA100?
The HPA100 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.

Can't live without it

My mom's allergy doctor recommended the Honeywell floor filter to her when she was suffering from seasonal allergies. It worked so well for her that she bought me one for my bedroom and I miraculously woke up not stuffy the next morning for the first time in months. So I bought a filter for each room and I can finally come home to fresh, clean air and breathe so comfortably all year round. I cant believe it made such a difference! And they're so easy to take care of, when the replace filter light turns red you just replace the filter and that's it!

better breathing from first night

I am particle-sensitive and would have to sneeze and blow my nose for about an hour each morning -- and sometimes so stopped up I could barely succeed in blowing my nose. After the very first night I used the unit in my bedroom, the problem was way way better. I then bought a unit for my office.

Great Filter

We are a medical office, and we love how quickly the filters work on perfumes, and tobacco smells. I can only imaging how well the work on viruses as well.

Good

So far I have no significant complaints. purchased about 2 weeks ago. Easy to use. the buttons on top are not the best quality. The adhesive was already coming a little loose when I received it

Very quite for bedroom

We had old air purifiers in each bedroom. They were noisy. We didn't like to use them. I bought one Honeywell, and liked it so much that I bought one for each bedroom. They filter better than the whole house filter system. They're quiet and affordable. The numbering system for the purifiers and filters is confusing, so I bought from Honeywell directly to be sure I had the right filters. The suggestion I would make to Honeywell is to conspicuously put the model number on the machine and in the manual.

Good Purifier

I grew up with Honeywell air purifiers, and my parents always got their money worth from them. As an adult, the local stores did not carry Honeywell so I bought an Idylis which I have used for last decade. Since that one went bad I opted to order Honeywell and have only had this one about a month. I like it thus far, it's not too loud and I like the light function on it as it acts like a nightlight in my bedroom. I don't necessary like the control button/methods but it seems typical for anything anymore. Considering ordering a larger model for my living room. Rating a 4 to be fair since I cannot speak for the life of this model.
