From the kitchen floor, a row of grease filters can look like a solid wall of stainless steel. Once those filters come out, the space behind them comes into view: the tracks and rails that hold each filter, and the accessible plenum where the duct begins.
That is why grease filter cleaning at Allen’s is done with the filters out. The cookline is protected first, the filters are removed, and their front, rear and baffle surfaces are cleaned. Then the tracks, rails and frames are cleaned, along with the accessible plenum behind them, before every filter is inspected and put back in place.
Pulling the filters can also show what a quick look from below misses: heavy buildup around the filter tracks, or a filter that is warped, damaged or the wrong size. Filters like that are replaced rather than washed again and again, and grease filter replacement is its own service at Allen’s.
