m1-1056 furnace filter

Three filters, same size

All three fit furnaces and A/C systems that take an M1-1056. Actual size 15 3/8 x 25 1/2 x 5 1/4, sold as a 16x25x5.

Camfil is rated for 6 months. Two changes a year instead of three, and it ships the same business day when you order before 11 a.m. Eastern.

Five Seasons is the original, the one your system came with. Rated 4 to 6 months, ships the next business day.

G1-1056 is a MERV 14, so it catches finer particles than the other two. It's also denser, so your system works a little harder to pull air through it. Ships the next business day.

Not sure which one? Call (888) 315-0105. We do this all day.
