Waterco Opal Cartridge Filters — Opal 135 · Opal 180
Minimal fuss, maximum clarity
The Waterco Opal Cartridge Filter is designed to eliminate the hassle of media-based filtration. The pleated reusable cartridge delivers high surface area for efficient dirt capture, meaning fewer cleanings and longer intervals between maintenance. Built tough with a polypropylene tank and easy-access screw-on lid, Opal makes pool care simple and durable.
Ideal where backwashing is difficult or water conservation is important, these filters perform under pressure and with low maintenance demands. With working pressures up to 250 kPa, temperature ratings as low as 4°C all the way to 50 °C, and high flow capacity, Opal keeps your pool sparkling without over-engineering.
