Show above are Aluminum Washable 'life long' type permanent Pre-Filters, followed by MERV 6 pleated secondary filters providing enhanced particulate arrestance, resulting in longer service life than the conventional low efficiency panel filter. Typically, 2" pleated type filters will last up to 6 months or longer, depending upon operating conditions, as compared to the typical 1 month life cycle of disposable fiberglass filters.  The deeper 4" pleated versions will typically provide even longer life cycles, up to 1 year or more.
