Open Education Webinar: Cleaning Air Solutions During a Global Pandemic

Cleaning Air Solutions During a Global Pandemic 8:00-10:00 am, ET, Feb.23, 2021, Zoom Online


8:00a-8:50a, Air Filtration in Response to COVID-19, by Dr. Thomas Caesar


There has never been as much public focus on Air Filtration as a safety requirement as it is today during the COVID-19 pandemic. The virus can spread from one person to another by different routes. Also, there are numerous variants of the virus that have surfaced with even more contamination avenues, making the challenge of control much greater.


Science: there is a strong indication that the coronavirus can spread as aerosols via the air.

Good News: the risk of infection by these direct routes can be reduced through social distancing, hygiene practices, and wearing face masks. There are many questions that you should ask yourself when selecting a mask.

  • Should everyone wear N95/FFP2/medical facemasks? What type of face mask should I wear, and what should I look for when looking when purchasing?

  • Will it stop all of the sneezing drops and coughing droplets from being inhaled?

Risk mitigation should always be at the forefront of our minds as we move through this challenging time as aerosols containing viruses can distribute with the air throughout a room and infect people even in more distance. Air handling units using high-quality and efficient fine filters based on specific guidelines given for the pandemic times can reduce the virus concentration in buildings to effective levels and minimize the risk. The key to minimizing the related infection indoors risk is the fast dilution of the contaminated room air to reduce the virus concentration, minimizing contact with hosts. But handling indoor air in the pandemic is a bit more complicated:

  • How should I design the air filtration systems? What is recommended for restaurants versus hospitals during the current pandemic?

  • What should we use for schools versus commercial buildings while the virus is aerosolized? Do we need a mask in the building?


Learning there are different ways coronaviruses can be transferred from one person to another, and no single measure on its own will give sufficient protection. A combination of all measures like social distancing, handwashing, wearing face masks, ensuring sufficient and high-quality ventilation of rooms, etc., gives a sufficient level of protection and minimizes infection risk. We will address these issues during this webinar.

9:00a-9:45a, HVAC Air Filter Inspection, Installation and Verification for updated CDC COVID-19 Guidelines, by Mr. Stephen Nicholas


With the advanced filtration technologies and air cleaning solutions, it is essential to know how to select the right filters for your HVAC systems to comply with ASHRAE, ASHE, JCAHO updated requirements and the latest CDC COVID-19 Guidelines and to ensure proper inspection, installation, and maintenance of the air filtration system for a safe and healthy indoor environment.


Mr. Nicholas will highlight and update the air filtration requirements associated with COVID-19 for actual field applications, such as hospitals, schools, commercial buildings, etc. We will discuss guidelines and examples on selecting air filters, scheduling filter change-out, and selecting proper air filter clips, latches, and gaskets to ensure an airtight filter seal. Three T’s (Technical Tips – Tricks of the Trade and Traps to Avoid) and 3M’s (Measure, Monitor, and Manage) to secure an effective air cleaning will also be discussed.


You Will Learn:

  • Properly Select HVAC air filters based on CDC Guidelines

  • Select the proper airflow resistance gage to measure static pressure accurately

  • Proper Inspection and Installation

  • Utilize the Three T’s … Technical Tips - Tricks of the Trade - Traps to Avoid

  • Select proper air filters, clips, latches, and gaskets to ensure an airtight filter seal

  • Using a handheld particle counter to verify MERV 13 or 14 performance.

  • Consider the Three M’s … Measure - Monitor and Manage your HVAC air filtration system

  • Comply with ASHRAE, ASHE, JCAHO requirements, and the latest CDC COVID-19 Guidelines
