Due to emerging awareness of Coronavirus and other airborne pathogens, General Filters Inc. and Canadian General Filters Ltd. have composed the following information regarding the effectiveness of our Second Wind™ UV Air Purifiers against airborne infectious pathogens.

Results in 53% degradation of Coronavirus in HVAC ducting in a single pass (continued degradation on subsequent passes)

Results in 40% degradation of Coronavirus in HVAC ducting in a single pass (continued degradation on subsequent passes)

Results in 49% degradation of Coronavirus in HVAC ducting in a single pass (continued degradation on subsequent passes)

All microscopic organisms require a specific UVC dosage for inactivation. UVC disinfection has been employed since the 1930’s for surgical device purification and other applications. Second Wind™ Air Purification Systems provide improved air quality to address factors identified by the Center for Disease Control that contribute to your respiratory health. Second Wind™ Air Purifiers are installed in the home’s HVAC unit and/or ductwork and are designed to disinfect the air as it circulates (“passes”) through the ventilation system. Are test results available on Second Wind product performances against airborne viruses? Yes! In 2013, Second Wind conducted an independent study with the Government of Canada and the University of Waterloo to test the effectiveness of our products against many airborne pathogens. The results of the testing are shown in the chart at right (NSERC ENGAGE Grant: EGP 433623-12). (Go to www.generalfilters.com or cgfproducts.com for complete a copy of the study.)

Test results were used to determine the treatment efficiency for various pathogens using the effective UVC dose required for disinfection. The performance of each system is based on a single pass through the ductwork used in the study. Subsequent passes result in continued degradation of the remaining virus.

Suggested Air Filter Replacement Practices to Follow During the COVID-19 Pandemic


Reducing the risk of spreading airborne pathogens

Certain precautions should be taken when servicing and replacing air filters, especially now and during cold and flu season. Healthcare facilities should take extra precautions year-round to reduce airborne infections. The National Air Filtration Association (NAFA) offers air filtration industry resources and guidance for hospital and healthcare facilities at www.nafahq.org

Air Filter Servicing and replacement

Today’s historic global pandemic has raised awareness of the importance of maintaining healthy breathable air inside our homes and other buildings. Standard HVAC filters should be changed at least every three months, or at the minimum recommendation of the air handler manufacturer. In situations where the HVAC system is used continuously, there is a lot of dust present, or there are pets living in the environment, the filter may need to be changed more frequently.

Maintaining healthier breathable air amidst the coronavirus outbreak.

HVAC filters can reduce but not eliminate the threat of infection. The coronavirus and the particulate it travels on is very small in size, and can range from sub-micron (less than 1.0 micron in size) and larger. High efficiency filters on the market today can trap particulate sizes that are likely to remain in air. Selecting the right filter can reduce risk while improving the quality of indoor air

The spread of the novel coronavirus (COVID-19) mainly occurs through respiratory droplet transfer from person-to-person within a close range of about six feet according to the CDC. The virus can be transmitted on skin, objects, and surfaces that a contagious person may cough on, sneeze on, or touch. Pathogens can also travel on dust and dirt particles as those particles move through the air. Therefore, the potential for airborne transmission through an HVAC system exists.

Recommended Parker filters for reducing airborne risk Parker HVAC filters are manufactured in the U.S. and engineered to the highest standards of design, quality, and assembly. When selecting a filter to combat the threat of airborne transmission, we suggest a minimum efficiency reporting value (MERV) rating of 13 to 16. The higher the value, the better the filter will be at capturing small particles. Our Sub-HEPA, HEPA, and ULPA filters provide the highest level of protection (up to 99.999% on 0.12 microns). Our MERV 16 rated filters provide 90% and higher efficiencies, capturing airborne particles that are the size of viruses.

The following high-efficiency filters are designed for commercial use. All of them meet Leadership in Energy Design (LEED) requirements. They can be ordered through our global network of Dealers and Distributors by visiting www.parker.com/hvac.

RenewAire ERV Calculator (ERV Calc)


Poor indoor air quality (IAQ) is a serious problem. In fact According to the Environmental Protection Agency (EPA) indoor air is two to five times – and occasionally greater than 100 times – more polluted than outdoor air  The EPA ranks indoor air pollutants among the top five environmental.

RenewAire has been a pioneer in Energy Recovery Ventilation technologies for over 35 years. Our Energy Recovery Ventilators (ERVs) improve people’s health, cognitive function, productivity and well being by enhancing indoor air quality (IAQ) in homes and buildings of every type. This is done energy-efficiently, cost-effectively and sustainable via fifth-generation, static-plate, enthalpy-core ERVs and Dedicated Outdoor Air Systems (DOAS) that reuse otherwise-wasted energy to condition incoming outdoor air.

The MD6-ES24VK fresh air kit from S&P allows fresh air to enter dwellings to meet building code and ventilation standards requirements through a 6” motorized damper controlled by a 24V temperature/humidity monitoring control. The control can command the central HVAC blower to help distribute the fresh air through the existing ductwork if necessary.
