The requirement mentioned that ventialtion system that supplies outdoor air to occupied spaces must has particle filters or air-cleaning device that has filtration media meeting MERV 13 or higher.
My question is could stand-alone air purifiers with MERV 13 or highter filtration media (with sufficient coverage area for the space) be considered as fulfilling the requirement? Since some interiors project are located in existing building that the fresh air system is not under project scope of work and the host building provision filter may not reaching MERV 13 requirement, the tenant (project owner) would consider to provide standalone air purifiers instead to treat the air pollutant.

Could someone speak to Hannah's question?
We have run into similar situations in which we provide on-site negative air machines with MERV 8 filters through construction, and the existing building system is not under scope or work, and/or cannot accommodate MERV 8 or 13 filtration media. Does this meet the intent of the requirement?

Hi Kena, I got response from LEED Coach below:
"The requirements state, "Each ventilation system that supplies outdoor air to occupied spaces must have particle filters or air-cleaning devices..." therefore a stand-alone air cleaning device located within the space would not comply. The project would still have to comply with the filtration requirements regardless of scope in order to earn Option 1."
