Filbur FC-2390 Spa Filter Cartridge

The best way to confirm compatibility is to check the part number printed on your existing filter cartridge or consult your spa owner's manual. You should also verify that your filter housing accommodates the FC-2390's dimensions, specifically the 13.25-inch length and 2.125-inch outer diameter.

The antimicrobial end caps are designed to inhibit the growth of bacteria, mold, and mildew on the filter itself. This helps prevent odors and keeps the filter material from degrading prematurely due to chemical exposure or biological buildup.

Yes, this cartridge is designed to be cleaned and reused. To maintain performance, rinse the pleats thoroughly with a garden hose to remove debris, and use a dedicated filter cleaner spray periodically to break down oils and scale that water alone cannot remove.

The sharp pleat folds increase the surface area available to trap dirt and contaminants. This specific design prevents the pleats from 'bridging' or sticking together, which allows water to flow freely through the entire filter area for more efficient cleaning.

The reinforced PVC core provides structural integrity, preventing the filter from collapsing or warping under high water pressure. This ensures the filter maintains its shape and filtration efficiency throughout its entire lifespan.
