Keeping your spa water crystal clear need not be expensive with Water TechniX replacement Spa Filter Cartridges. All our replacement cartridges are designed to be a straight swap with your existing cartridges from popular spa cartridge filters like Bullfrog, Waterway, Monarch, Aquaswim and more!


Just like the Water Technix pool filter cartridge line, we’ve decided to work with a reputable pool filter cartridge manufacturer to produce brand-specific replacement spa filter filter cartridges at a fraction of the cost of the genuine spa filter cartridges.
All of the Water TechniX spa filter cartridges are designed to work with a specific spa cartridge filter system, we don’t carry a one-sized-fits-all solution as each spa filtration system has its own design that must be followed to ensure that filtration is at optimal levels.
The Mr Pool Man Guarantee!
The Water TechniX range of spa filter cartridges are the only replacement spa filter cartridges that are backed by a 100% satisfaction, money back guarantee for a full 12 months!. We’re so confident in our replacement spa filter cartridges that we’re guaranteeing that they work as well (or even better!) than genuine spa filter cartridges at twice or thrice the price!
REEMAY Filter Elements
All of the Water TechniX Spa Filter cartridges are manufactured using USA REEMAY Filter material. REEMAY is one of the world’s most trusted names in filter media. Not only does the REEMAY Filter material filter as good as the ones the genuine spa filter cartridges use, but it has the advantage of being more chemical resistant as well. REEMAY Filter elements are extra heavy duty and are resistant to chemicals that will often turn your generic filter elements into mush. They’re also built to withstand frequent cleaning cycles which makes them last much longer than your typical generic filters.
Localized Construction and Design
The Water TechniX spa filter cartridges are designed with the Australian weather in mind so warmer water temperature and higher spa chemical concentrations won’t affect the performance of the Water TechniX Spa Filter Cartridges!
