Features

  • [NSF/ANSI 50 CERTIFIED] Doheny’s Pro-Grade Replacement Filters are manufactured according to ISO9001 Certified Quality Management System and implemented into the Environmental Management System according to ISO14001. All Filters are manufactured in high-tech, clean, and sterile environments. We take your family’s health and safety as seriously as we do our own!
  • [FILTER SPECIFICATIONS] Length: 10 1/2”. Outside Diameter: 8 1/2”, Top Opening: 3”, Bottom Opening: 3”, Filtration Area: 65 Sq. Ft., Core: Upgraded OEM High-Strength ABS Injection Molded.
  • [COMPATIBLE MODELS] Doheny’s PWK651 Replacement Filter for Watkins Hot Spring Spas. Replaces Pleatco PWK65, Unicel C-8465, Filbur FC-3960. NOTE: This is a compatible replacement filter and the manufacturer’s names and part numbers have been used for your reference only. Doheny’s is an independent brand.
  • [IMPROVED TECHNOLOGY] Unlike cheaper Tri-Lobal filters, Doheny’s Filters boast a single layered, 4-oz. Point Bonded Filtration Fabric, which is the highest quality spun bonded polyester material available. It doesn’t fray or tear and is resistant to chemical degradation. Point Bonded fiber shape is more efficient, delivering 20-40% greater effective surface area and helps catch smaller particles which increases filtration efficiency without water pressure drop – MEANING LESS FILTER CLEANING!
  • [UNIQUE FILTER CONSTRUCTION] Doheny’s Replacement Filters feature and upgraded high-strength ABS injection molded center core that helps ensure safety, strength, and efficient water flow. Additionally, Doheny’s only uses reinforced end caps on all filters! We insert a high tensile strength mesh screen into the caps that adds strength and structural integrity to the end caps. Filter bands are strategically placed to ensure the entire filtration area can be efficiently used.
