Most used spa cartridge filter for jacuzzi's (spas) in South Africa. The housing is complete, but no cartridge inside.
A spa filter cartridge is essential to clean water and remove debris.
Benefit of having a cartridge filter for spas:
- Cartridge filters are much smaller than sand filters which is the alternate option for spas;
- Cartridge filters remove finer debris from water than sand filters, thus filtrates better;
- Heat-loss through the filter housing is less than with a sand filter due to the smaller outside surface area;
- Clean of cartridge filters takes less water than the "backwash & rinse cycle" of sand filters;
- Finally its uses up less space in a compact pump-box and is nowadays commonly installed in jacuzzi's / spas.
