This study reviewed the previous research on the airborne transmission of SARS-CoV-2 in indoor environments from the perspective of indoor air quality (IAQ) and its control. In order to reduce the airborne transmission risk, many control strategies have been introduced, including personal protective equipment (PPE), improved ventilation and air distribution, standalone air cleaning and disinfection technologies, and occupancy control and restriction.
Creating a healthy building through engineering controls in spaces is a key component of combatting COVID-19. It’s a strategy that balances overall effectiveness with the financial impact it can have on the business.

No two HVAC systems or applications are the same. And solutions are plenty, varied and can be layered to maximize effectiveness. That is why Carrier takes a consultative and comprehensive approach to understanding your HVAC system, building and occupants’ needs.
Carrier assessments provide a custom roadmap for your particular HVAC needs. Ask your local expert to suggest HVAC system design and equipment upgrades, replacements, service plans and analytics to maximize system efficiency and longevity.
Actions you can take to improve indoor air quality (IAQ)
Your customized Carrier IAQ solutions suggestions may include equipment, controls and service that address various aspects of your HVAC system and building needs as noted below.
Maximize outdoor air ventilation • Monitor & control target ventilation
From simple tweaks and settings adjustments to adding new or retrofit equipment, bringing in more fresh outside air to replace indoor air can help reduce airborne pathogens and other contaminants.
One option: Install an OEM or retrofit Economizer feature on your packaged rooftop unit(s), and enjoy the money-saving benefits of free cooling while introducing more fresh air into your facility.
Filter air at MERV 13 or higher • Implement advanced purification solutions
The higher the MERV rating, the more efficient the filter. ASHRAE recommends MERV 13 whenever possible. Other air purification solutions range from UVGI (Ultraviolet Germicidal Irradiation) using short wavelength UV (UV-C) to high-voltage electrostatic filters (capturing particles with high voltage and ionization fields) and photocatalyst using titanium dioxide to decompose organic compounds.
Simply and easily increase filtration with this portable, air-cleaning solution that can remove contaminants and discharge cleaner air back into the room. Roll it into place and plug it in to a standard electrical outlet to supplement your existing HVAC system.
Control to 40% - 60% relative humidity
Depending on your building design and location, you may need to add OR remove humidity to meet established guidelines. Keeping indoor relative humidity within the ASHRAE® 55 suggested range (40% - 60%) can minimize the effects of bacteria and allergens.
Possible recommendations: If your building is in a hot, humid state, we may suggest our Humidi-MiZer® adaptive dehumidification system. If your building’s air is too dry, we’ll refer you to companies that specialize in humidifiers.
Implement multipoint IAQ monitoring • Incorporate advanced IAQ controls
Let Carrier test your indoor air quality and develop and implement upgrades to help ensure: optimal filtration, ventilation, airflow, controls, and more. Carrier experts can also develop corporate-wide IAQ engineering standards and help implement them.
Facility management tools help building operators manage occupant comfort, energy efficiency, and overall building health.
Carrier Commercial Service provides BluEdge, a new best-in-class service and aftermarket offering. Central to BluEdge is a progressive, tiered service model, that provides a range of dynamic options to meet the needs of your business.
Safe Start Service helps get your building ready for occupancy through a rigorous recommissioning of your HVAC equipment and implementing best practices.
Providing building occupants with real-time visibility into air quality metrics promotes the health and safety of their surroundings.
Design to appropriate comfort standard • Advanced localized controls
Thermal health is a result of proper and acceptable conditions (humidity, temperature, etc.) necessary to obtain indoor human comfort. Without a proper thermal health, people may feel too tired or distracted. Your local Carrier expert can help by matching key products to address particular issues keeping in mind that your site is unique thereby requiring a unique solution.
