Guardian Air QR+
Reliable Air Purifying Services in Melbourne
The Guardian Air QR+ is an in-duct air purifier that clears the air of
microbials, bacteria, mold, and more. As part of RGF® Environmental
Group’s air purifying line, this system differs from other filtration
units because air does not need to reach the air handler for the system
to remove the pollutants. Rather, it releases advanced oxidation plasma
(AOP) to destroy pollutants at the source in the air and on surfaces.
The Guardian system utilizes RGF’s patented PHI-Cell® technology and can be mounted on your existing cooling and heating system.
Advantages of the Guardian air purifying system include:
- The unit comes in three convenient sizes to accommodate your needs
- Can reduce mold, viruses, and bacteria
- Can eliminate odors caused by cooking, pets, smoke, and more
- Kills 99% of sneeze germs within 3 feet
- Provides whole home purification
It is recommended that licensed HVAC contractors and technicians install these products. At Weather Engineers, our skilled team has extensive training and experience handling the Guardian Air QR+. If you’re considering adding one to your home, we can survey your property and make suggestions as to which size would be right for you.
Once you decide which unit is right for you, we provide quick and efficient installations. The nice thing about the Guardian systems is that it has low maintenance requirements. Unlike other filtration systems that require frequent filter changes, the Guardian QR+ just needs the PHI-Cell® replaced every 2 years, which only take 5 years.
Go ahead and breathe easier with an air purifying system that works for you! To install a new Guardian QR+ system or to have an existing one serviced, call (321) 727-2542 today!
