Which vendor is this?
Just the factory-authorized one from Santa Fe, I think.
My heating guy said not to use expensive high MERV filters, but rather cheap Fiberglas filters replaced more often. He said the better filters have worse airflow, causing your fan to work harder and break sooner?
This is specifically for a dehumidier and the airflow is quite slow, I think. Maybe 150 cfm? Anyway, the devices ship from the Santa Fe factory with MERV 13 filters.
