We are pursuing IAQ during construction and we are using MERV8 filters on supply air grilles. I also understand that during construction MERV 8 filters are the norm for use on supply or return air grilles permanent equipment. As Steve above, anyone could please confirm this?

Yes- MERV 8 filters during construction are all that are required even if you are pursuing IEQc5.

O'kay. So, in accordance with SMACNA 2nd edition 2007, ANSI/SMACNA 008-2008 (Chapter 3), (which I'm assuming would be used for all versions of LEED New Construction since the newest standard should take precedence, right?), at least MERV 8 filters are required for use during construction and during building flush-out but what about just immediately prior to occupancy? Is MERV 8 still the minimum requirement? The intent and requirements link does not specify which rating to use then.
