Built for real-world installs and long Kiwi Summers, the new BWT ES Series top-mounted media filters combine smart handling features with a seriously durable tank design.

The BWT Essential Series (ES) Media Filter is the perfect balance of performance and affordability, offering a cost-effective solution for reliable domestic pool filtration. Fitted with a 40mm top-mount multiport valve, it ensures easy operation and seamless integration to your pool maintentance. Engineered for strength, the tank combines a cross-wound bobbin weave exterior with a dual-fibreglass inner shell delivering exceptional durability and long-lasting performance for years of crystal-clear water.
