Photohydroionization®

(PHI-CELL® or Photo-hydro-ionization) is an advanced Indoor Air Quality (IAQ) technology developed by RGF Environmental Group to minimize and neutralize indoor air pollutants such as bacteria, viruses, mold, gases (VOCs) and odors.

PHI-CELL® utilizes a broad-spectrum, high-intensity UV light targeted on a hydrated quad-metallic catalyst. The UV light in conjunction with the catalyst promotes the conversion of naturally occurring water vapor into airborne molecules of hydrogen peroxide (H2O2). These airborne H2O2 molecules revert to oxygen and hydrogen once they have come in contact with a pollutant.

Safety

It is a normal reaction to question the long-term safety of any product that is effective and uses new or ‘breakthrough’ technology. This type of question has become common with the growing demand for safe, effective, and reliable indoor air quality devices.

Hydrogen peroxide naturally occurs in the air and was originally discovered in the early 1800s during experiments to “decompose” air. Additionally, it has been shown to be produced naturally via photochemical, chemical, and biological processes(1). Over the past 20 plus years, RGF® has more than four million advanced IAQ products successfully used worldwide without a safety problem.

The breakthrough in RGF’s PHI-CELL® advanced IAQ technology is the controlled creation of hydrogen peroxide. Hydrogen peroxide is created in our atmosphere whenever three components are present: Oxygen molecules, water vapor, and energy (sunlight photochemical).

Low level, airborne hydrogen peroxide is highly effective at destroying harmful microbials in the air and on surfaces. The PHI-CELL® advanced IAQ technology found in RGF’s Guardian Air, REME-HALO® and HALO-LED™ product families has brought natures antimicrobials found in the outside air back into the conditioned space of your home or business.

Sneeze Test - REME HALO®

A testing protocol concept was used which included a "Sneeze Simulation Machine" and "Sneeze" chamber. A sneeze can travel at up to 100 mph, so we had to consider lung capacity, sneeze pressure, and liquid volume to properly simulate a human sneeze. This was accomplished and the test proceeded with outstanding results. An average of greater than 90% reduction of microbials was achieved with REME HALO® in a double blind test, at two (2) feet from the sneeze source*. This is clearly not a medically supervised test or protocol. However, from a practical point, it was definitely providing some kill at the source and will provide some level of protection.

Testing Summary: 99+% Inactivation of Avian Influenza (Bird Flu)

Avian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not die from them. However, avian influenza is very contagious among birds and can make some domestic birds, including chickens, ducks and turkeys, very sick and kill them. Of the few avian influenza viruses that have crossed the species barrier to infect humans, H5N1 has had the largest number of detected cases of severe disease and death in humans. Of the human cases associated with the H5N1 outbreaks in poultry and wild birds in Asia, Europe, the Near East and Africa, more than half of those people reported infected with the virus died. While there has been some human-to-human spread in H5N1, it has been limited, inefficient and un-sustained.

Testing Summary: 99+% Inactivation of H1N1 Swine Flu

The H1N1 flu virus, or swine flu, caused a worldwide pandemic in 2009-2010. It is now considered a seasonal flu, which continues to circulate seasonally worldwide. Spread of the H1N1 virus occurs in the same way that seasonal flu spreads. Flu viruses are spread mainly from person to person through coughing or sneezing by people with influenza. Sometimes people may become infected by touching items – such as a surface or object – with flu viruses on it and then touching their mouth or nose. Kansas State University completed preliminary testing on RGF’s Photohydroionization® (PHI-CELL®) and Reflective Electromagnetic Energy (REME® Cell) technologies with 99+% inactivation of H1N1 Swine Flu on a stainless steel surface.

Testing Summary: Ethylene levels were reduced 85+% within 12 hours

Ethylene is a naturally occurring small hydrocarbon gas that serves as an aging hormone in plants. Ethylene gas will ripen tomatoes, bananas, pears and a few other fruits postharvest. Premature ripening caused by naturally occurring ethylene gas will negatively influence the fruit’s texture and color, as well as shorten the time cycle for processors to ship to market. By reducing ethylene gas levels, PHI treatment provides the packing house with more time to process and ship before spoilage. A controlled test was performed where high levels of ethylene gas were introduced into a test chamber (25ppm), and when treated with a PHI cell the gas levels were reduced to 3.6 ppm in 12 hours.

Tests were conducted using an ASHRAE compliant HVAC testing system connected to a secondary test chamber.

Mini-Split PHI unit

We installed a ductless system in our service department for both heating and air conditioning summer of 2016. The service office is next to our parts room which serves both install and service departments. Needless to say there is a steady traffic flow past the indoor unit and at times 6-8 service technicians in the same room the air conditioner. Within two months of the install of our air conditioner, unit blower wheel and evaporator coil blowing black debris across the office. Air filters where being cleaned monthly. We cleaned unit every two months and had to pull blower wheel out every time due to the excessive buildup of grim. For a year we did this same process and also had to treat / sanitize coil for dirty sock smell about every 3 months during air conditioning season. In 2017, we installed the PH230RGF UV light. We had previously installed several of these systems for our customers and want to put it to the test for ourselves. (Seeing is believing) and all my service technicians were sick of cleaning this unit in the office. Since the install of the PHI-230 we are back to a normal cleaning cycle of once every 6 months, blower wheel has not been pulled for 2 years and looks like new yet. Unit no longer needs sanitized for dirty sock smell. Out of the eight other indoor units, this unit is typically the cleanest unit, with the most foot traffic past it. Our service, sales, office and install staff can now see the difference between no UV light and having a UV light. Seeing is believing, our technicians are talking to more customers and selling more products due to they believe in the product. Having that peace of mind for our employees to talk to customers and make recommendations to improve IAQ at our customers’ homes and office is priceless. This only validates that we are not selling “smoke and mirrors” but we are selling products that work and we use them ourselves.

A product that DELIVERS!

The REME-HALO has tremendously helped nullify or reduce dramatically pet and kitchen odors. However, I bought the unit for relief from allergy symptoms and the REME has been extraordinary on that front, too. I’ll buy another, in the future, I’m 100% sure. A product that DELIVERS!

— KJ Austin, TX

All I have to say is WOW!!!

I have been working in the HVAC world for years. I have seen products come & go but I have become a believer. I manage a duct cleaning crew & have a lot of questions sent to me about allergies, dust, mold, & how to keep a home as allergen free & dust free as possible. Once I found out about RGF I dove into the technology & decided to install a REME Halo into my own home BEFORE I sell a single unit.

My home was built in the 1950’s, 3,000 sq feet home with 1,500 sq feet main floor & a matching basement. The HVAC system was installed in 1995 as a 3.5 ton AC & Furnace. 1 exterior door is sealed & the other is not. I have a mix of single pane wood framed windows & double paned fiberglass. It is not a completely sealed house YET. I also personally cleaned my own HVAC system not 2 years ago.

Normally I change my 2 inch thick MERV 8 filter every 2 months. The pleated material looks the color of cardboard. 1 MONTH after I had installed the REME Halo the same filter, which was installed brand new with the REME Halo, the filter was dark brown like Hot Chocolate. I was Floored!!

During that same month my outdoor only cat, which is fed right next to the unsealed exterior back door, was sprayed by a SKUNK!! The poor cat had a yellow line on her chest for weeks. This all happened while my family & dogs were inside asleep. By morning my whole house reeked of Skunk. So I went down to the basement, opened the REME Halo and opened the sleeve WIDE OPEN. To my amazement, the skunk odor that seept into my house was gone within 2 HOURS!!!!!!

All I have to say is WOW!!!

These products like the REME Halo have and continue to do their job. Great stuff!!!

Oh & I am now selling them

Cedar Fever

I send you New Year’s greetings because of the Reme-Halo product. Normally at this time of the year, I would be very uncomfortable inside and out due to cedar fever but I am truly thankful to you for the introduction of the Reme-Halo into my life.

Kim Saunders from ABC Home & Commercial Services installed the Reme-Halo in my home on 11/16/18 and I remembered from talking to you, Todd Montgomery, District Instructor for the Reme-Halo, that I should check my filters early after running my HVAC fan 24/7 since I didn’t have a newer programmable system. I changed those filters on Christmas Day as it was 2 months to the day, (I usually do it every 3 months) since they were changed. I thought you might appreciate a visual.

So, so dirty after 2 months which I think means the Reme-Halo is doing its job. But even more importantly, I haven’t awakened in the middle of the night with a headache since soon after my Reme-Halo was installed. And when I have had a cedar spasm away from my home, once I was home, my immune system settled down and I didn’t feel bad. That is impressive to me as cedar has been a major problem to me for years. And that makes me thankful for the investment I made.

I have shared my story with several people but I think the three of you ought to get together and create a TV ad that combines ABC Home and Commercial Services with RGF’s Reme-Halo. I have seen ABC’s ads on a variety of generic solutions but the Reme-Halo could help many more Austin homeowners if you would be more aggressive with telling your viewers the value of the Reme-Halo. I am so appreciative that I had Kim Saunders to my home who shared the technology with me and I appreciate that you, Todd Montgomery, took the time to help me understand your product. All Austin needs now is you, Bobby Jenkins, to do a commercial that tells Austinites the value of the Reme-Halo. I encourage the three of you to get together and make Austin residents more comfortable as the Reme-Halo has made me.

Thank you for working together and I am sure this new year will bring more success to your businesses.

— Happy New Year! K.T.

Formaldehyde contamination

Thank you so much for installing the REME HALO Air Purification System on our home. We were in a desperate situation to find a way to decontaminate our home from a formaldehyde contamination. New furnishings we had purchased May 1, 2015 was highly contaminated with formaldehyde and remained in our home for two months before we realized it’s toxicity had infiltrated our home and had caused sever health issues with my wife. My wife’s face, neck, chest, arms and hands became highly inflamed and then infected, the doctors told her that her home was still contaminated and that is why it would not heal.

When we told Russell of our crisis with our home and health he and Ryan were immediately at our door the next morning. Ryan made a simple attachment to our existing furnace system of the HALO filter within an hour. He stated that within 5-7 days we would see an improved difference Within 48 hours we could tell a difference in the toxicity in the home and within a week the home air quality was very much improved. My wife began to see a significant healing with her burned skin and skin infection by two weeks. Her doctor was amazed at her quickened improvement. We are positive it is in part because of the HALO filter system. We gladly placed in our doctors hands information on the HALO system. He was very impressed.

What Russell and Ryan R. stated the system could perform is exactly what occurred, within the exact time period. We highly recommend this system to anyone who is seeking an air purifier for their home.

— Sincerely, V and J H.

RGF’s whole home air purifiers are installed in your air conditioning duct and work actively throughout the air-conditioned space to reduce bacteria, virus, mold spores, odors and allergens. UV lights provide passive treatment of air conditioning coils.

  • Please refer to our Dealer Locator to find a dealer near you. All licensed HVAC contractors have access to the product through their local distributor.
  • Contractors, please contact your local HVAC Distributor for pricing and availability of the RGF products.

The output of the unit reduces with time. After two years (up to 25,000 hours) of operation, it is recommended to change out the replaceable cell.

We are happy to say that no maintenance is required once the unit has been installed!

The best location for your REME HALO® or Guardian QR+ unit is in the supply plenum, just after the air handler. This allows for optimal operation and full distribution throughout the air-conditioned space.

Yes, if the HVAC system does not allow space to accommodate installation in the supply plenum, installation on the return side of the air handler is acceptable.

Yes. RGF recommends installing 10-12 inches downstream of the humidifier/dehumidifier, before the first drop of the ducts split off.

For optimal performance and maximum cell life we recommend that the REME HALO® and Guardian Air QR+ be wired so that it runs continuously.

The REME HALO® and Guardian Air QR+ treats your home when the air conditioning fan is on. If possible, it is recommended to leave your fan on continuously to provide maximum benefit. While cycling the air purifier on and off with the fan is acceptable, be aware that repeated cycling may degrade the useful life of the cell elements. Therefore, it is recommended to run the air purification units continuously.

The indicator light on the REME HALO® was changed from green to red in November of 2017. The light simply indicates that the unit is powered. If the light is on, whether the color is green OR red, your unit is receiving power.

Some people may notice a slight smell after installation and some people don’t notice anything at all. It has been described as similar to fresh, clean outdoor air, but can be stronger at first for those who have a particularly keen sense of smell. You will notice the smell subdue over time. If not, consult with your installing HVAC contractor.

If you are one who happens to love the smell that the REME HALO®/Guardian Air produces throughout your home or work place, you may feel as though it has stopped working when you can no longer smell it. It’s ok! It is still working! Rest assured that if the indicator light is on, your system will continually provide over 2 years, or over 25,000 hours of fresh, clean, purified air.

If your indicator light is on, your unit is working and will provide up to 25,000 hours, or over two years of fresh, clean, purified air.

The shroud positioning has no effect on the life of the REME cell. The shroud will only help to control the output of the REME HALO® based on the air flow of the air conditioning system.
