Hi Sajjad,
You may be able to pursue Option 2 of the credit. But, filtration is required per ASHRAE 62.1-2010 and thereby EQp1 Minimum Indoor Air Quality Performance in a couple of circumstances. The first is that filters or air cleaners having a minimum efficiency reporting value (MERV) of not less than 6 shall be provided upstream of all cooling coils or other devices with wetted surfaces through which air is supplied to an occupiable space per section 5.8 of the standard.
Also, if the project is located in a non-attainment area for PM2.5, the project must have MERV 11 or higher filters.
