• [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.
