COVID-19 Mitigation Strategies in HVAC Systems

Bipolar Ionization

Bipolar ionization is increasing in popularity at since COVID-19. Many manufacturers are boasting benefits such as reduced odors, pollutants, and allergens in addition to helping with COVID-19.  There are no known downsides. A couple of our local HVAC representatives in the industry have products that have been tested against SARS-CoV-2 (COVID-19) with beneficial results. These systems are available on a wide variety of scales, from small to large. They are relatively cheap and easy for a contractor to install.


Another important strategy is utilizing filtration to the highest level that is appropriate for each HVAC system, as well as implementing a proper maintenance schedule for regular changing of filters. The filters will catch the particulates in the air that the virus, other bacteria, or allergens might attach to.

Portable Air Purification

The CDC (Centers for Disease Control and Prevention) recommends using portable high-efficiency air filtration systems for the safe reopening of schools and office buildings, with additional consideration to include UVGI (ultraviolet germicidal irradiation) as a supplemental technique to inactivate potential airborne viruses of common occupied spaces.1

UV Light

Ultraviolet Germicidal Irradiation, or UVGI, uses light in the UV-C spectrum to disinfect water, air, and surfaces. This proven technology has been in use since the mid-20th century, primarily to disinfect wastewater. This part of the light spectrum is harmful to any biological material, including people, so care must be taken in implementation.

Air can be disinfected by irradiating the upper room air only, the full room when it is empty or protective clothing is worn, or air as it passes through HVAC systems, according to the National Institute of Health.


Bipolar Ionization


How Bipolar Ionization Works

NPBI™ safely cleans air inside commercial and residential buildings. The patented technology uses an electronic charge to create a plasma field, filled with a high concentration of positive and negative ions. As these ions travel with the air stream, they attach to particles, pathogens, and gases.

  • The ions help to agglomerate fine sub-micron particles, making them filterable.

  • The ions breakdown harmful VOCs with an electron volt potential under twelve (eV<12) into harmless compounds like O2, CO2, N2, and H2O.

  • The ions inactivate pathogens by disrupting surface proteins.

  • The ions travel within the air stream into the occupied spaces, cleaning the air everywhere, including spaces unseen.


Plasma Air is the leading innovator in indoor air quality by manufacturing HVAC and portable air purification products that result in healthier, more productive indoor environments in institutional, commercial, residential, and industrial applications. The Plasma Air HVAC purification systems use highly efficient plasma ionization technology to neutralize indoor air pathogens and pollutants. Plasma Air systems have been proven in thousands of applications to provide the highest level of air quality improvement for airports, train systems, schools, hotels, casinos, arenas, offices, and homes.

Effective, Safe & Affordable Full-Facility Air Purification System

Plasma Air offers a comprehensive indoor air quality solution for educational facilities where students and staff are exposed to dangerous and irritating pollutants such as bacteria, viruses, volatile organic compounds, odors, dust, pollen, and mold spores. Maintaining optimal indoor air quality in schools can reduce absenteeism, improve academic performance and enhance student and staff productivity. In addition, by utlizing ASHRAE's IAQ Procedure, engineers can save school districts significant equipment and energy costs by reducing outside air intake. Plasma Air is installed in hundreds of schools around the country. 



Air Purification



Room Air Purifier

In today’s world, indoor air quality is an increasing concern and the ability to provide clean air to room occupants is more important than ever. Most commercial spaces focus primarily on cost and thermal comfort while air quality is based on minimum requirements, which can result in lower than optimal air quality.

The Room Air Purifier (RAP) is an ideal option for improving indoor air quality wherever and whenever you need it, particularly in high density areas like office spaces, classrooms, fitness centers, retail and restaurants. It is designed to continuously cycle air through a HEPA filter, eliminating unwanted dust particles, germs and contaminants. 

The RAP uses an internal fan to draw air into the return, through a HEPA filter, and then send the air back into the space through a grille. With the fan continually running, the air in the occupied space is consistently filtered to provide purified, clean air.


The Room Air Purifier (RAP) is an ideal option for any indoor spaces where additional fitration is desired, including office spaces, classrooms, hotels and more. The RAP improves indoor air quality with air. It is designed to continuously cycle air through a HEPA filter, eliminating unwanted dust particles, germs and contaminants.
