With these strong pleats, and supporting bands to keep them in place throughout your filters lifespan, you will enjoy longer filter cycles with reduced maintenance. A no-BS filter that does what you expect it to, isn't that refreshing? 3X Tougher End Caps: Our revolutionary design, developed over 3 years, features filter end caps made of a two-component polyurethane sealant and special reinforcing fibre that can withstand expansion at alternating temperatures, without cracks or splits like other brands of elements on the market. 2X Stronger Cores: Precision engineered free flowing cores are reinforced with advanced design supports to ensure they do not collapse or implode, which is quite common with inferior pool filter elements. The Water TechniX filters are GUARANTEED to last. To sum it up, our Water TechniX pool filter cartridge is a high-quality aftermarket pool filter element that effectively removes impurities from your pool water, ensuring crystal clear and safe swimming water.
