Lennox 30335 Air Filter

The Lennox 30335 Air Filter is a heavy-duty, 16" x 25" x 1" washable foam filter designed for high-performance filtration in professional HVACR applications.

Common Questions

Can the Lennox 30335 be used in place of MERV-rated pleated filters?
Yes, this filter is specifically designed for systems requiring a 1" washable solution or as a direct replacement for the P-8-7822. Always verify system static pressure requirements before switching media types.

How often should the washable foam be cleaned?
In standard residential or light commercial applications, the foam should be inspected monthly and washed every 90 days. For heavy-use or high-dust environments, monthly cleaning is recommended to prevent excessive pressure drop.
