Air Purification

What’s the difference between the REME and Guardian?

Both of these units take care of bacteria, mold spores, viruses, VOCs, and odors, and the REME HALO® has the added benefit of removing particulates from the air (dust, dander and pollen)

How is the REME HALO® and Guardian QR+ different from a UV light?

Pro-Active Air Purification Hydroperoxides and other friendly oxidizers created by the REME HALO® and Guardian Air and are carried into the conditioned space via blower to where people are living, breathing and sneezing killing, airborne and surface bacteria and viruses, neutralizing odors, and reducing particulates (dust, dander and pollen).

How often do I need to replace the cell (bulb)? How do I know if the cell needs replacing?

The output of the unit reduces with time and, after two years of operation, it is recommended to change out the replaceable cell

Is there any maintenance to perform on the system besides replacing the cell every two years?


Where is the best place to install the REME HALO® or Guardian unit?

The best location for your REME HALO® or Guardian QR+ unit is in the plenum, just after the air handler. This allows for full distribution and extended air treatment. In situations where it is somehow impossible to locate the unit after the HVAC unit, it is acceptable to locate the Guardian Air™ unit before the HVAC unit; however, the high moisture content of the cooling coils, as well as the high temp of the heating coils, will reduce the effective treatment capacity of the unit.

Can I install your unit in the same area with a humidifier or dehumidifier?

Yes and RGF recommends installing the unit 10 – 12 inches above the humidifier/dehumidifier.

What is the best way to connect/wire the REME HALO® or Guardian unit?

We recommend for optimal performance and maximum cell life that the Guardian Air product line operates continuously.

Should our central air system run all the time so your system is always working? Is it better to have the A/C unit working 24/7?

The Guardian Air unit treats your home when the HVAC unit fan is on. It is recommended to leave your fan on continually when possible to provide maximum benefit. However, cycling the unit on and off with the fan is acceptable, but be aware that excessive repeated cycling may degrade the useful life of the cell elements. We recommend running the unit continuously.

Is there a chart for adjusting the REME HALO® shroud for cfm coverage?

Yes – see chart
