I have a Carrier 3.5 ton, 1/2HP air handler (Model Number:fc4bnf042
). I have been using MERV 13 a/c filters for a few years now because my son has allergies. I recently discovered that the higher MERV filters can cause resistance that can strain the blower. Does anyone know if there is a simple way of determining whether I am OK with the MERV 13?
How to determine which MERV filters would be best for the air handler
air-conditioning

One website I found is selling filters in the same range as yours for that model.
Outside of checking with Carrier, though, I can't think of an absolute answer.
