The simple and intuitive touch panel makes it easy to control your personalized settings, and the Balance comes with the added convenience of a wireless remote control. The air purifier features four distinct operating modes and includes an air quality indicator that automatically adjusts the machine to match the air quality in the room.

    Brondell O2+ Air Purifier FAQs

    How much granulated carbon is in your filters?

    6.5 ounces of granulated carbon in each filter.


    What is a True HEPA filter and what does that mean?

    A True HEPA filter qualifies as HEPA (high-efficiency particulate arrestance) under U.S. government standards, which means the air filter must remove (from the air that passes through) 99.97% of particles and allergens including dust, smoke, pet dander, mold spores and pollen that have a size of 0.3 microns or larger.


    Do your filters utilize Mechanical or Electrical filtration techniques?

    Our Balance and Source air purifiers use mechanical filtration only and do not generate ozone during the filtration process.


    What certifications do your filters have?

    Our Balance and Source air purifiers have AHAM (Association of Home Appliance Manufacturers), California ARB (Air Resources Board), and Energy Star certification.


    How many cubic feet does your filter purify?

    AHAM recommends that the air filter CADR (Clean Air Delivery Rate) rating, multiplied by 12, should be equal to or greater than the cubic feet volume of the room. Brondell's smoke CADR rating is 157, therefore our recommended room size is 1884 cubic feet. However, the room can be a bit larger and the product will still perform very well, as CADR rating does not take into account other Brondell filtration methods (such as carbon, which reduces odor and VOCs).


    What replacement battery type is required for Balance Remote control?

    Battery type is a CR2032 coin-style battery.


    I have the Balance and the remote is unresponsive. What's wrong?

    Please remove the battery and flip the battery around and try again. If that does not resolve the issue, please contact Brondell Customer Support at 888-542-3355.


    Why does the remote for my new Balance look dirty and used?

    There is a clear plastic protective film on the remote control that sometimes becomes worn during shipping. This film should be pulled off the remote control before use.


    My brand new air purifier doesn't work and the filter won't turn on.

    Please make sure the plastic has been removed from the filters before use, and please make sure they are inserted correctly - with the arrows on the filters pointing to the front of the filters. If that does not resolve the issue, please contact Brondell Customer Support at 888-542-3355.

    Balance Air Purifier is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Scrubbing the Air After brain surgery (seriously) eight weeks ago, I needed to clean the air in my home office and bedroom so I purchased two Brondell's after doing some extensive research on air purifiers. Well two weeks into service at home and I have to say they have exceeded my hopes of making my recovery and home environment healthy. I work mainly from home and feel comfortable that the air quality (units are set on "Auto") is affording me the best possible chance of a healthy recovery. The air has a fresh (after a rain-fall) quality and I just sent my mom a unit for her apartment. Do yourselves a favor if you are reading this review and questioning a Brondell purchase, you will not be disappointed.

    Rated 5 out of 5 by from Fantastic service! I bought the O2 Balance about a year ago, and have loved its functionality so far. When it came time to replace the filter, the light wouldn’t reset - apparently a manufacturer issue with one of the parts. Dale at Brondell walked me through about 90 seconds of trouble shooting and then issued a replacement. Very friendly service, and the replacement came quickly. Very happy.

    Rated 5 out of 5 by from Received it today Fast service and a beautiful quiet unit. I am looking forward to cleaner air! We live in a rural area and our house is full of dust even with weekly cleaning and we have 2 dogs and a cat. This unit is nice looking and seriously cannot believe how quiet it is! I love that it can be in auto mode and determines the air quality on its own.

    Rated 5 out of 5 by from Impressive I bought this air filter about 5 weeks ago, and I have noticed a huge difference in the amount of dust in my condo. Instead of needing to clean the dust every week, I now can clean once a month in my main living area. It also is really sensitive to smells in the air.

    Rated 5 out of 5 by from Very helpful product! We have a couple of large dogs that shed a lot causing breathing difficulties for my wife and me. The Balance Air Purifier has changed all that. We both breathe much better now.

    Won’t restart after filter replacement, why

    Asked by: Kaoskeiper
    I have dealt with this issue before - they issued us a new unit after about a month. I’m coming here today because I am experiencing the EXACT sane issue once again. Very disappointing. The rest button appears to be faulty.
