Keeping pool and spa filters in good condition plays a big part in keeping your water clean, balanced, and easier to maintain. Over time, water filters collect all sorts of fine debris, oils, and particles—so replacing the cartridge when it’s due helps everything run better and keeps the water looking clear.
Here you’ll find a range of NZ-made Magnum filter cartridges, built to fit most standard spa and pool systems. They're easy to install, well-made, and designed for solid, everyday use. Whether you’re replacing an old one or stocking up for the season, these are made to handle the job properly.
