Disposable models are much cheaper, but require monthly replacement, therefore it is best to have several on hand in order to save you time throughout the year. Permanent brands are more cost-effective due to their reusability but require more work because of the routine cleaning. All HVAC air filters come with a MERV (Minimum Efficiency Report Value) Rating.

HVAC Systems and the Spread of COVID-19

HVAC Systems and the Spread of COVID-19 Modifications to HVAC Systems (heating system, ventilation system, and air conditioning system) might help reduce the spread of COVID-19 by purifying air, improving ventilation, and managing airflows. To reduce risk in older buildings with ventilation systems that recirculate air: Open doors and windows, even when it’s cold outside. Ideally, open multiple points in enclosed rooms, so air can flow in and out. Use fans and air circulators to speed up the exchange of air through windows and external doors.Use portable air purifiers with HEPA filters.Use filters with a Minimum Efficiency Reporting Value (MERV)…
