Yeah, my reply was meant to indicate if we were self-isolating for whatever reason, it’s good to know the HVAC and filtering system in our house would provide a reasonable amount of fresh air. In no way did I mean to imply that this would help filter out COVID-19 or any other viruses, although a MERC-16 filter can help in that regard (which can cause an additional strain on the HVAC). We’re using a MERC-13 filter instead of the standard MERC-10 that comes with the HVAC we have.
But tell me now you in Central Texas, did Cheyenne Bowdie, or the Rifleman, etc. need HVAC?:)
