The Guardian QR+ is designed to eliminate at source odours, air pollutants, VOCs (chemical odours), smoke, mould, bacteria and viruses with advanced oxidation technology in every cubic metre of air in your home or office.

Combat Sick Building Syndrome with Guardian QR+

The Guardian QR+ kills germs and reduces odours throughout the ventilated space. It doesn’t need the pollutants to travel through the ductwork to be neutralized. Instead it enriches the air passing through the duct with natures “friendly oxidizers” which is distributed throughout the property and which breaks down the bacteria, virus, mould spores, odours at source into their harmless constituent components – oxygen, CO2, water vapour etc. A good example of how this works is the human sneeze. Germs come out with a sneeze at 160 km/hour. With Guardian QR+ installed and the internal air enriched, 99% of the germs in a sneeze are neutralized before the germs travel 1 meter from the mouth. The AOP Cell will reduce or eliminate smoke odours, cooking odours, pet odours, rubbish odours,“musty” or stale air odours, formaldehyde, paint odours and chemical odours.

Advanced AOP technology

The unit uses patented technology at its core which significantly reduces odours, pollutants, VOC’s, smoke, mould, bacteria and viruses found in the indoor air. The Guardian QR+ is easy to mount into ventilation ductwork/plenums. When the HVAC system is operating, the Guardian QR+ cell creates an advanced friendly oxidation process consisting of hydroperoxides, ozonide ions, super oxide ions, and hydroxide ions. These friendly oxidizers break down the pollutants back to their harmless constituent components – oxygen, CO2, water vapour etc.

Guardian QR+ GA models are suitable for larger spaces, producing up to 40,000 m3 of purified air per hour.

The Guardian QR+ unit size is scaled to accommodate the various air flow rates of different HVAC systems. Match the supply ventilation rate of your HVAC system to that of your Guardian QR+ unit.

The Guardian QR+ utilizes patented technology and is easily mounted into your existing ventilation 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 living space. Unlike passive air technologies, which need pollutants to pass through the unit for purification or filtration, the Guardian QR+ enriches the AOP onto the airstream which then sweeps through your home actively purifying pollutants at 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 break down 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 or HALO LED.

• Available in three sizes (5”, 9”, 14”) to accommodate blower sizes from 300-18,000 CFM
• Reduces bacteria, mould, viruses and odours
• Unlike portable units that are limited to the room in which they are placed, the Guardian QR+ provides whole home and building purification.
• Easily integrated with your existing HVAC system, the unit doesn’t take away living space and operates silently.
• The core technology can reduce sneeze germs by 99% by the time the sneeze has reached 3 feet.
• Low maintenance: No costly filter changes, all you need is a cell replacement every 2 years and only takes 5 minutes.
• The Guardian QR+ has a quick-release feature for easy, no tool cell replacement.

• U.S. Military approved for mould reduction in field hospitals.
• U.S. and International Hospital approval for the fight against infectious disease: 99% reduction of Staph (MRSA)
• Major U.S. city school reports 20% reduction in absenteeism
• Tested and approved by the Chinese government for protection against the deadly SARS virus.
