Traditional HVAC filters capture large particles well, however, that’s not enough. Circulating throughout the indoor air of most buildings are smaller particles, such as viruses, bacteria and Volatile Organic Compounds (VOCs). Unfortunately for occupants, even the most efficient HEPA filters will miss capturing all of these small-sized contaminants.
HIGHMARK has partnered with Genesis Air to bring to market an air-purifying solution that doesn’t rely on capturing particles. The technology is called Photocatalytic Oxidation (PCO), which destroys organic compounds by turning them into CO2 and water.
By destroying harmful contaminants, such as viruses, bacteria, bioaerosols and VOCs, indoor air quality (IAQ) is greatly improved. This supports high-level sustainability certifications, such as the WELL Building Standard, among others.
PCO air purifiers can cut down on unpleasant odors. Inside the panels, hydroxyl radicals accelerate the breakdown of most VOCs by destroying the molecular bonds. This helps combine the organic gases to form a single molecule that isn’t harmful to humans, thus enhancing the air-cleaning and odor-mitigating efficiency.
For example, odor molecules that are minimized come from such substances as tobacco, formaldehyde, nitrogen dioxide, urine and fecal odor, gasoline and many other hydrocarbon molecules in the atmosphere.
The PCO oxidation reaction takes place at the coated surfaces within the air purifier. Unlike Bi-Polar Ionization or Ozone systems, the oxidizers created are always contained inside the cleaner. As a result, no reactions take place in the occupied space where occupants could be harmed.
Cartridge or pleated-style filtration add significant pressure drop to an airside system, thus increasing energy consumption. PCO technology introduces less than 0.05” of static pressure at 500 feet per minute, which will have no effect on fan energy consumption. This makes it easy to retrofit into any HVAC system.
The effectiveness of contaminant removal in a single pass without a filter was tested by RTI International, an independent nonprofit research institute. RMI found that the PCO air purifier offers tremendous efficacy in removing contaminants, including:
Genesis Air incorporates a revolutionary technology into their Photocatalyst GAP™ to reduce airborne biologics and VOCs. Key differentiators include:
The below diagram outlines how PCO air purifiers convert harmful contaminants into benign materials:
By implementing PCO air-treatment panels in hospitals and all types of commercial buildings, the number of airborne viruses, mold, bacteria and VOCs can be significantly reduced.
This is especially true since ASHRAE confirmed the movement of bioaerosols by air-handling units (AHUs). Accordingly, PCO air-treatment panels act as a first line of defense against contaminants entering an indoor space.
What’s more, cleaner indoor air has proven to drastically slow and minimize surface contamination. Subsequently, because many infections occur from touching contaminated surfaces, cleaning the indoor air will help to alleviate this issue.
The Coronavirus (COVID-19) is airborne and can live up to three hours in the air. The virus particles are also small and can penetrate through HEPA filters. Therefore, utilizing PCO air purifiers to kill the virus in indoor spaces can work well. Consider these points from Genesis Air:
In the challenging situation presented by the Coronavirus (COVID-19), it’s critical for consulting engineers to be as informed as possible. For this reason, HIGHMARK and Genesis Air compiled detailed air-filtration guidelines, which can be accessed by clicking on the accompanying image.
Hospitals are increasingly challenged by rising patient infection rates, especially from hospital-acquired infections (HAIs), such as methicillin-resistant Staphylococcus aureus (MRSA).
MRSA causes about 80,000 infections and 11,000 deaths annually in the U.S. and up to $4.2 billion in costs. It’s especially difficult to remove from indoor spaces because the bacteria travel easily through the air.
The best way is to prevent MRSA from spreading is with PCO air-cleaning technology that specializes in airborne infection control. PCO systems destroy all bacteria, such as MRSA, and integrate seamlessly with existing HVAC systems.

Hospitals need PCO air-purifying technology to fight MRSA, improve airborne infection control and reduce HAIs. Here are four reasons why hospitals heed PCO to fight MRSA:
