I agree that we need more fresh air introduced through HVAC systems however….Preventative maintenance programs will become critical! Increasing fresh air will bring in more outdoor particles (dust and allergens), requiring regular filter changes.
Also a clean coil will be more critical than ever as the equipment will have an added load.
As this begins to be implemented, here are a few things that can be done:
- Good filtration to keep dirt off the coil and allergens out of the occupied area.
- Consider bipolar ionization to further reduce particles (before filters if using below MERV 13 or in supply if MERV 13 filters can be used).
- Consider UV lights on the coil to keep the clear of the natural form bio-film. Without addressing these areas, I can see a drastic increase in allergy related problems and HVAC equipment issues.
