Furnace Replacement Filter for 16x25x5 Air Cleaners with MERV 11 Media and Greater Dust-Holding Capacity
This furnace replacement filter uses MERV 11 media to capture airborne particles before they collect on your system's coils. Its larger media capacity provides greater dust-holding ability than one-inch filters, making it a practical replacement for compatible home air cleaners.
The genuine Lennox X6670 HCF16-11 has a nominal size of 16x25x5 inches and actual dimensions of 15-3/4 x 24-3/4 x 4-3/8 inches. Match both the dimensions and your air cleaner model before ordering. Single-filter, two-filter and five-filter packs let you buy one replacement or keep spares ready for later maintenance.
