@CorsIAQ @JimRosenthal4 @DavidElfstrom @joeyfox85 we have MERV-8 & MERV-10 filter stock.Instead of recycling it all, is it possible to say use 2 MERV-10 filters (layered) to help improve filtration ability? If we stack 2 MERV-10s together, then could they filter like a MERV-13?
@A_Dobbie11 @CorsIAQ @JimRosenthal4 @joeyfox85 Don't stack filters in a HVAC system meant for a single filter. In a DIY CR box, go with a single MERV-10 only. Capture efficiency is still good because of the lower velocity. Total CADR should be highest with single filter because 2 would decrease flow.
@DavidElfstrom @CorsIAQ @JimRosenthal4 @joeyfox85 Ok. We were planning on using MERV-10 to build more desktop CR boxes. As long as the MERV-10 can still help filter our airborne pathogens via multiple passes, then we will use them👍
