Hayward W3T-CELL-3 Replacement: Compare 2 Options

Maker's cartridge vs aftermarket: the W3T-CELL-3

We did not find Hayward's own W3T-CELL-3 on Amazon. 2 brands sell a salt chlorinator cell listed as its replacement, including A-Outsanding, Autopartsfreer.

• Maker's own part: made and sold by the equipment maker (for example Hayward or Pentair). Usually the highest price.
• Cross-reference and aftermarket parts: Unicel, Pleatco, Filbur and others make parts to the same size and specification and publish the matching numbers. Usually cheaper; materials vary by brand.
• Before you buy: compare the size, both end openings and the filter area with your old part, and confirm your filter or spa model on the product page.
