Source True Hepa Air Purifier

With its three-stage advanced purifier system, the O2+ Source eliminates allergens such as dust, smoke, pollen (including tree, grass, and ragweed), pet dander, mold, odor, and harmful VOCs. The certified True HEPA filter removes 99.97% of particulates and allergens above 0.3 microns, while the granulated activated carbon filter effectively reduces smoke, foul odor, and harmful off-gassing VOCs including formaldehyde and benzene.

The simple and intuitive controls provide personalized settings for every member of the family. Additionally, the air purifier features four distinct operating modes, including an air quality indicator that automatically adjusts the machine to match the air quality in the room. With its sleek and compact design, the O2+ Source is ideal for any home or office.

    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.

    Source Air Purifier is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Allergy Saver! My 9-yr-old son developed allergies this year, and is especially sensitive to dust and the extent that he would sneeze uncontrollably and have pouring eyes all the time, even in his own bedroom. My pediatrician recommended that we get a high-end air purifier that cleaned the air of allergens - and after doing some research I landed on the Source and bought two - one for his bedroom and one for the living/dining room. Since we've started using them you'd never know how bad his allergies are - there's virtually no sneezing and he rarely has to take medication. It's literally changed his life. If you suffer from airborne allergies, I couldn't recommend this air purifier more highly.

    Rated 5 out of 5 by from Excellent achat ! Cela fait plus d'un an que j'ai ce filtreur à air et il est incroyable. J'ai des problèmes d'allergie et de respiration et je le laisse dans ma chambre. Même durant la saison des pollens, mes symptômes ont extrêmement diminués. Je vous le conseil!

    If I work in a lash extension studio will this take care of the fumes from the glue?

    Where can I get a fuse for this air purifier? It seems like a specialty item as none of the hardware stores in my area nor Amazon carries that size, volt and amp combination.

    Asked by: Teresa1234
    Hi Teresa, There is actually a spare fuse in the plug, you can access it by following the instructions on page six of this manual: Best

    I am not able to see This model listed on ARB.CA.GOV. If this model has just been approved recently, can you please state whether this model is a "Mechanical" or an "Other" using California Air Resource Boards standard? Thank you!

    Asked by: Gwenne
    Thank you for your question. Our O2+ Air Purifiers have been tested and have passed the California Air Resources Board testing and we will be listed on the website shortly. Our O2+ Air Purifiers are "Mechanical Filtration Only" using physical filters: Mesh, Activated Carbon, and True HEPA.
