" Airborne transmission of SARS-CoV-2
is signifi cant and should be controlled.
Changes to building operations,
including the operation of heating,
ventilating, and air-conditioning
systems, can reduce airborne
exposures. " - ASHRAE Pandemic Task Force
Considerations For
Reopening During COVID-19
Ventilation and fi ltration are important tools in the eff ort to stop the pandemic
Don't:
Do:
Use MERV 13 fi lters or highest rating your system
can handle
Use the correct size fi lter and ensure fi t is good
Use in room fi ltration and UVGI to supplement
ventilation
Ensure at least 62.1 VRP ventilation rates
Increase Ventilation as much as possible
Measure and maintain ventilation rate
Ensure directional airfl ows within and exiting the
buildling are desirable
Use well established methods and products
Assume all fi lters rated the same, perform the same
Think it is good enough; A 1/4 " gap can reduce
installed performance by 1 or 2 MERV values
Assume one size fi ts all; Review CADR and UV-C
coverage area
Use products that reduce ventilation rates per
person (Rp) using IAQ Proceedure
Rely on a single adjustment and balance
Use CO2
, temperature, or damper position as a
surrogate for direct measurment
Adjust outdoor air intake without attention to
exhaust or other ventilation systems
Use technologies with unsupported claims
