I just had a new Carrier 59TP6B060V171214 furnace installed with a 16x25x5 inch filter housing. What's the max Merv rating that the furnace could handle? I would like to use a Merv 15 filter if possible.

Answer:

My recommendation would be to upsize your filter cabinet when going for a more restrictive filter. As more filter area will give better airflow.
