Lennox X0583 Air Cleaner Filter

The nominal size is 16 x 25 x 5 inches, while the actual dimensions are 16 x 24.75 x 4.375 inches. Manufacturers use nominal sizing as a standard industry label, but the actual dimensions are slightly smaller to ensure the filter slides easily into your specific housing unit without binding.

For standard heating and cooling systems, you should replace the filter every 6 months. If you use your system exclusively for heating, it can typically last up to 12 months, though you should inspect it periodically for heavy debris buildup.

Yes, this filter is compatible with specific Honeywell models, including the F25F1000, F35F1008, and F100F1012, in addition to the Lennox BMAC 16x25 unit. Always verify your current filter's model number or housing dimensions before purchasing to ensure a proper fit.
