Guardian Air QR+

The Guardian Air QR+ is an in-duct air purifier capable of purifying every cubic inch of air that your central heating and air conditioning system reaches. Proven to eliminate bacteria, viruses, mold and VOCs, the Guardian QR+ is also very effective at reducing unwanted odors from cooking, cleaning chemicals, pet areas, smoke and musty air. Say goodbye to smelly, stuffy, musty rooms and hello to fresh, clean, pure air throughout your home or office building.

The Guardian Air QR+ utilizes RGF’s patented PHI-Cell® technology and is easily mounted onto your existing air conditioning and heating system air ducts. When the HVAC system is in operation, the Guardian QR+ creates an advanced oxidation plasma (AOP) that is distributed through the duct system into the conditioning living space. Unlike passive air technologies, which need pollutants to pass through the unit for purification or filtration, the Guardian QR+ sweeps through your home actively purifying pollutants at the source. The advanced oxidation plasma consists of hydro-peroxides, oxide ions and hydroxide ions. All are friendly oxidizers that are found in nature’s process of cleaning the outdoor air and are safe for humans and animals alike.

Note: The Guardian QR+ is an air purifier and not a filter. It does not reduce particulate matter like dust. For an air purifier with added particulate reduction and that is even more effective at removing allergens, you’ll want to have a look at the REME HALO®.
