REME HALO® Whole Home In-Duct Air Purifier

The award winning REME HALO® whole home in-duct air purifier is the next generation of indoor air quality (IAQ) technology and capable of purifying every cubic inch of air that your central air conditioning system reaches. Designed to eliminate sick building syndrome risks by reducing odors and air pollutants, the REME HALO® whole home in-duct air purifier is the best solution for whole house and building air purification.

Invented to recreate nature’s process of purifying the air, it’s like bringing fresh outdoor air inside without ever having to open your windows. And it’s effective against all three categories of indoor air pollutants: Particulates, Microbial and Gases.

You can now reduce common allergy triggers from particulates such as pollen, mold spores, dander and dust. Thoroughly tested on airborne and surface bacteria & viruses, such as MRSA, e-coli, and Norwalk, to name a few. Say goodbye to odors from cooking, pets, dirty socks, diaper pails, and musty rooms.

RGF® PHI-Cell® and REME HALO® Technology – Impact on Novel Coronavirus (COVID-19)


From the World Health Organization, “Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).” Further from WHO, “COVID-19 is an infectious disease caused by the most recently discovered coronavirus. This new virus was unknown before the outbreak began in Wuhan, China, in December 2019.”

RGF® manufactures a range of air purification and air filtration products for residential, commercial and healthcare applications. This bulletin aims to answer frequently asked questions for our distributors.

Are test results available for RGF’s PHI-Cell® or REME HALO® on COVID-19?

We currently do not have testing specifically on the Wuhan Coronavirus (COVID-19). We are evaluating testing options with partners in both U.S. and China. As there are a limited number of facilities capable of testing for this virus, their focus is on prioritizing testing as it relates directly to the recent outbreaks.

Is RGF’s PHI-Cell® and REME HALO® technology effective at reducing COVID-19?

COVID-19 is a member of the enveloped RNA coronavirus (subgenus sarbecovirus, Orthocoronavirinae) subfamily. While RGF® does not have testing specifically on COVID-19, we have validated test results showing 99+% reductions on similar viruses. These viruses, like COVID-19, are also ‘enveloped’ or protein jacketed virus types. If we can reduce these virus types, an assumption could be made that we would also be effective at reducing the current coronavirus at hand. Important to note that we make no medical claims.

Does RGF® have products approved for use in hospitals and healthcare settings?

Yes, RGF-BioControls® product line includes the Microcon® MAP and Microcon® ExC7 HEPA filtration units designed and proven to reduce risks associated with airborne infectious pathogens like COVID-19 in hospital settings. The Microcon® MAP and ExC7 are FDA 510k compliant ‘Class II medical devices’ and designed within CDC guidelines for treatment of infectious airborne pathogens and in the creation of Airborne Infection Isolation Rooms (AIIR).

Can RGF’s PHI-Cell® and REME HALO® products be used in hospital settings?

Many hospitals have approved and installed PHI-Cell® and REME HALO® products throughout their facilities. Using FDA 510k compliant Microcon® products in patient rooms for acute care, in combination with PHI-Cell®/REME® installed in the HVAC ductwork offers a thorough response to infection control. It is recommended in the hospital setting to employ multiple, redundant air purification technologies to achieve best results.

While reviewing this bulletin Dr. Marsden (KSU) commented, “This virus apparently is similar to other viruses that we previously tested. There is every reason to believe that RGF technologies would be effective in reduction of COVID-19.” In combination with RGF® technologies it is recommended to always follow antimicrobial protocols and procedures per regulatory guidelines.

Disclaimer: PHI-Cell® and REME HALO® technology has not been tested on coronavirus (COVID-19) and is not a medical device therefore no medical claims are made. Testing conducted by independent accredited labs and universities.

How We Help You Improve Indoor Air Quality


UV light is a potent killer of fungi, bacteria, and viruses. Installed in your A/C or HVAC systems, this technology can stop mold, mildew, and harmful germs from building up and circulating around your home.


Dry air in your home can irritate your nose and throat, trigger nosebleeds, and leave you vulnerable to infection. Our whole- house humidifier systems make it easy to maintain optimal humidity.


Too much humidity can be just as harmful and provides a breeding ground for mold, mildew, and bacteria. We can help you to dry out damp rooms and keep humidity levels under control.


Your HVAC system is only as good as its ducts. We can provide duct maintenance, repair, replacement, sealing, and cleaning to make sure your ventilation system is running at optimum performance.


Clean air is healthy air, but some pollutants are difficult to eliminate. We can install air purifiers directly into your HVAC or A/C to capture pollutants and keep fresh, clean air flowing throughout your home.


Efficient heating and cooling systems take care of your health, your home, and your wallet. We can provide installation, maintenance, and repair to keep your systems running smoothly.


Radon levels in the Cincinnati area are higher than the national average. The EPA strongly suggests every home be tested to make sure occupants are not exposed to dangerous levels of radon gas.
