Cartridge Filter Spaflo 25 housing complete with lid, but without inner cartridge

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.
