Is a CI project required to replace the filters of the main building AHU? The project is a 5000 sf office space tenant in a 162,000 sf building (no AHU's in the space). All grilles and ducts were covered with MERV 8 filters during construction (not using the HVAC system was not an option since it serves the rest of the building). The form asks for the Pre Occupancy Filter Replacement Date and what MERV rating they were replaced with. It doesn't seem practicle to have to replace the main building filters, but not replacing them doesn't seem to be an option. What should CI projects do in this instance?
