2200 which is a merv 12 . Is this too much restriction ?
16x25x1
Is that a 4.5" thick filter? Thicker filters are usually less restrictive than 1" filters. You would have to check the temperature rise, the external static pressure and drop across the filter and make sure it's not too high.
Those are furnace killers. If your keeprite furnace doesn't already have a cracked heat exchanger, these filters will put the final nail in coffin.
Also if used with an ECM blower, you can say goodbye to any hydro savings.
I advise all my customers to never use these, they just have too much restriction.
No it's just a 1 inch .....??
