Test Results

Below you will find a summary of some of the testing and studies performed by third party independent labs and universities. Smart Air Care products are not medical devices and no medical claims are made.

The results of a third-party study reveal PHI-Cell Technology® efficacy of 99.9% against the SARS-CoV-2 virus, commonly known as the coronavirus 2019 or COVID-19.

Commencing in March 2020, the study was overseen by Dr. James Marsden, Executive Director of Science and Technology at RGF. “The study results show the PHI Cell technology inside the REME-HALO® to be effective in combating the COVID-19 virus and a valuable solution to immediately improve the Indoor Air Quality of residential and commercial spaces and protect occupants against exposure to the SARS-CoV-2 virus.” The studies are ongoing.

The independent third-party study focused on the inactivation of SARS-CoV-2 using PHI- Cell® technology. The testing, performed at the Innovative Bioanalysis Laboratories in Cypress, Calif., looked at neutralizing the virus within the occupied space in the air and on surfaces.

The test procedure used the SARS-CoV-2 virus, live virus not a surrogate, inside a large chamber (1,280 cu. ft.) representing a real-world air-conditioned office or room. The virus was nebulized into the space simulating a sneeze or cough from an infected person. With the REME-HALO (with PHI-Cell Technology® ) operating inside the chamber the virus was reduced on contact, resulting in a 99.9% reduction of the virus within the simulated real-world space.

The PHI-Cell® active air purification system testing showed the SARS-CoV-2 virus was significantly neutralized within the occupied space on airborne virus, reducing the risk of person-to-person infection by respiratory particles and aerosols. The PHI Cell technology® is an “active” solution that neutralizes SARS-CoV-2 within the occupied space.

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 lung capacity, sneeze pressure, and liquid volume had to be taken into consideration to properly simulate a human sneeze. This was accomplished and the test proceeded with outstanding results. An average of 99% reduction of sneeze germs was achieved with PHI/ REME® in a double blind test, at three feet from the sneeze source.

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.

Norovirus is a highly contagious virus and as few as 10 viral particles may be sufficient to infect an individual. Infections of the virus can occur by consuming contaminated food or water, by touching contaminated surfaces, or from person-to-person transmission. Norovirus is named after the original strain “Norwalk virus,” which caused an outbreak of gastroenteritis in a school in Norwalk, Ohio in 1968. The most common Norovirus outbreak settings include healthcare facilities, restaurants and catered events, on cruise ships and in schools. 50% of all food-borne outbreaks of gastroenteritis can be attributed to norovirus.

Bacillus cereus is a gram-positive, facultatively aerobic spore-former whose cells are large rods and spores do not swell the sporangium. These and other characteristics, including biochemical features, are used to differentiate and confirm the presence of B. cereus. These characteristics are shared with B. cereus var. mycoides, B. thuringiensis and B. anthracis. B. cereus food poisoning is the general description, although two recognized types of illness are caused by two distinct metabolites. All people are believed to be susceptible to B. cereus food poisoning.

Escherichia coli, usually abbreviated E. coli, are a large and diverse group of bacteria, which are found in in the lower intestines of mammals. Some strains such as enterohaemorrhagic E. coli (EHEC) that are pathogenic can cause severe foodborne illness. Outbreaks are most often linked to raw or undercooked meat products, raw milk, and fecal contamination of vegetables.

Legionella is a group of pathogenic bacteria that is one of the most frequent causes of waterborne disease in humans. They are found naturally in the environment, and grow best in warm water. One type of pneumonia caused by Legionella is called legionellosis, or commonly known as Legionnaires’ disease. The disease is transmitted when people breathe in a mist or vapor with the bacteria. However, they do not spread from one person to another person.

Methicillin-resistant Staphylococcus aureus (MRSA) is a type of bacterium responsible for difficult to treat infections due to its resistance to certain antibiotics. These antibiotics include methicillin and other more common antibiotics such as oxacillin, penicillin and amoxicillin. Staph infections, including MRSA, occur most frequently among persons in hospitals and healthcare facilities (such as nursing homes and dialysis centers) who have weakened immune systems. In the community, most MRSA infections are skin infections. In medical facilities, MRSA causes life-threatening bloodstream infections, pneumonia and surgical site infections. RGF along with a major hospital participated in a two-year study evaluating PHI technology, which resulted in a 33.4% reduction in infections.

Staphylococcus aureus, often referred to simply as “staph”, is a bacterium commonly found on the skin and in the nose of people. Person-to-person transmission is the usual form of spread and occurs through contact with secretions from infected skin lesions, nasal discharge or spread via the hands. People infected with staph experience nausea, vomiting, stomach cramps and diarrhea. It is usually mild and most patients recover after one to three days.

S. pneumonia is an exclusively human pathogen and is spread from person-to-person by respiratory droplets, meaning that transmission generally occurs during coughing or sneezing to others within 6 feet of the carrier. The bacteria can cause many types of illnesses, including meningitis, ear infections, sinus infections, and bacteremia. Health experts estimate that more than 10 million mild infections (throat and skin) like these occur every year.

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. It typically attacks the lungs, but can also affect other parts of the body. It is spread through the air when people with infection cough, sneeze, or otherwise transmit their saliva through the air. Most infections are asymptomatic and latent, but about one in ten latent infections eventually progresses to active disease which, if left untreated, kills more than 50% of those so infected.

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.

Formaldehyde is a colorless, flammable, strong-smelling chemical that is used in building materials and to produce many household products. It is commonly used as an industrial fungicide, germicide and disinfectant. When formaldehyde is present in the air at levels exceeding 0.1 ppm, some people may experience adverse effects including burning sensations in the eyes, nose, and throat, watery eyes, coughing, nausea, as well as skin irritation. The purpose of this test was to evaluate the effect RGF’s Advanced Oxidation Technology has on formaldehyde.
