Clean and Comfortable Air

Revive your home atmosphere with clean comfortable air. Don's just filter your air, refresh it with the Brondell Revive air purifier and humidifier.

IT'S NOT JUST AN AIR PURIFIER... The Revive is a premium True HEPA air purifier and unique humidifier. Don't just filter your air, refresh it with the Revive! Adding moisture to filtered air not only helps relieve allergy symptoms, stuffy nose, and sinus congestion, but it also effectively relieves dry skin and reduces asthma symptoms. Super-efficient evaporative humidification makes for a more consistent humidity level and won't over-saturate the immediately surrounding area.

Evaporative Humidification

Using evaporative humidification and dual true HEPA filtration, Revive doesn’t just purify the air but refreshes it as well. Air is drawn in through two suction points on the front and back of the unit, where it’s passed through dual carbon and true HEPA certified filters, removing 99.7% of all particulate matter, allergens, and pollutants. With evaporative humidification, water is wicked up through a specialized filter, where the air then passes through and is evenly distributed throughout your home, instead of concentrating around the unit or damaging furniture with dense vapor pockets. This means steady, clean, quenched air without the damp spots of traditional steam vaporizers or impeller humidifiers.

With a dual suction system, the Revive is able to move through more air faster than comparably sized machines and super-efficient evaporative humidification makes for a more consistent humidity level.

Product Highlights

Dual True HEPA Filters
Dual True HEPA filters remove 99.97% of particulates and allergens larger than 0.3 microns. Dual suction and dual True HEPA filters mean this machine is working double time for you.
Humidifier Filter
This humidifier filter operates similar to an air washer trapping dust and other air particles in the filter so they are taken out of the room's atmosphere.
Active Carbon & Specialized Filters
The Revive contains a granulated carbon filter, which traps and removes odors, harmful gases, and VOCs. The Revive also comes with an Off-Gassing Reduction filter. Using a proprietary catalyst, this filter effectively removes invisible substances like formaldehyde and VOCs that contribute to "Sick House Syndrome" and can cause health and respiratory issues. Other Specialized Filters are available for purchase separately.

Frequently Asked Questions

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 µm (micron) or larger.

What is a true HEPA woven carbon filter?

Brondell's woven carbon formula effectively reduces smoke, odor, and harmful off-gassing VOCs, including formaldehyde and benzene.

What certifications do your filters have?

Our O2+ air purification products are certified by nationally recognized industry standards associations such as Association of Home Appliance Manufacturers (AHAM), California Air Resources Board (CARB), Energy Star, and Edison Testing Laboratories (ETL) respective to their efficiency and performance. For complete details, please reference your unit’s spec sheet.

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).

Specific CADR ratings based on the unit are as follows:

  • Halo: 156
  • Revive: 230
  • Horizon: 218


What is the air coverage for your O2+ purifiers?

Specific exchange rates for each model:

  • 197.9 cu. Ft. per minute/242 sq. ft.



  • Regular Residential Use: 627.5 sq. ft. (3 Air Changes Per Hour)
  • Allergy Sufferers Use: 376.5 sq. ft. (5 Air Changes Per Hour)
  • Humidifying Capacity: 350 ml/hr



  • 280 sq ft (2 air exchanges per hour)
  • 560 sq ft (1 air exchange per hour)


Do any of your systems generate ozone?

Our Horizon is equipped with an Intelligent Ion filtration mode which will trap positively charged ions, including irritants such as allergens, dust, and bacteria. This generates trace amounts of ozone when the feature is active.

Are the O2+ air filters recyclable?

Unfortunately, O2+ air filters are made from woven polyester fibers and are not recyclable at this time.

Where is it made?

Brondell O2+ models are made in Korea and China.

What is the required power?
