Then I think I found the right guy for this question. How is the air flow different for the same filter with same MERV rating but different thickness? Say 1'' pleated vs 2'' pleated. Is it similar, or drastically reduced at 2''?
And also, I bought Accumulair MERV 13 for my office HVAC system the other day because it is cheaper than the Filtrete 2200, but I am not sure which one has higher air flow, do you have any opinions on a good 1'' filter?
