The pandemic has hit an all-time high in cases and continues to create heightened concern for the quality of the air we are breathing – especially inside buildings. As a result, commercial building owners and managers must re-evaluate building HVAC services and implement system improvements. Specifically, air quality and circulation must be addressed by implementing an air purification system that will improve air quality and meet CDC standards for commercial operations.
The Airborne Spread of COVID-19
Aerosolized droplets from a COVID-19 infected individual can spread to others very quickly through natural breathing. Reducing the number of people in a space to increase personal space and distance and using masks can decrease the transmission through the droplets. However, a commercial building equipped with an HVAC air purifier will circulate clean air through the building and increase outside air (OSA) to further reduce the transmission of the germs carried by the airborne droplets keeping everyone safer.
“Based on recent research, aerosolized droplets can remain airborne for up to three hours, making the potential for spread in crowded and confined spaces…problematic,” said Dr. Robert Glatter, an emergency medicine physician at Lenox Hill Hospital in New York City.
Therefore, cleaner air with increased circulation can reduce the probability of the droplets remaining airborne and spreading from one person to another.
Solving Through Air Purification
With experience in air quality control and HVAC system improvements, The BP Group is helping commercial spaces make changes through air purification.
In general, commercial buildings should consider implementing the following precautionary measures to ensure the health and safety of their occupants:
- Install High-Efficiency Filters – review the efficiency rating of existing air filters and consider upgrading to those with a higher MERV (Minimum Efficiency Reporting Value) rating.
- Clean and Sanitize Evaporator Coils and HVAC ductwork – Use sanitizing evaporator by applying Evap-Fresh Spray, an EPA registered antimicrobial odorless product. This will remove and kill bacteria restoring HVAC unit sanitization.
- Install an HVAC Air Purifier – Ionization is an air purification system that delivers ionized air molecules that can attach to airborne pollutants and remove 95% from breathable air. A UV light air purifier in air conditioning ductwork or evaporator coil stops microbiological growth and destroys up to 85% of contaminants.
- Increase Outside Air Supply – To dilute pollutants released by equipment, building materials, furnishings, products, and people, an HVAC system must deliver and circulate an adequate amount of outside air supply. This process requires a careful distribution of air that accomplishes dilution, creates a cleaner space, and also maintains a comfortable environment.
Air purification upgrades for commercial HVAC systems are installed to address airborne viruses and bacteria to reduce the spread of germs, such as SARS-CoV-2.
Audit Your Air Purification System
The BP Group professionals can review the existing HVAC system by observing the sanitization processes and measuring efficacy. They will also track air circulation and provide options for improvements that will help building occupants stay safer and healthier through the air they breathe.
