Product Overview

Product Description

203 x 125mm  Vortex Threaded Purezone Spa filter 400 cartridge

This replacement filter may also suit some other spas.

Whilst conventional filters trap particules as small as 50 microns (50/1000th of a millimetre) the purezone micro filtration is 10 times more effective, trapping particles as small as 5 microns (5/1000th of a millimetre).

Does your Vortex or O2 have 3 filters? If so this is the correct Purezone filter for you.

See the filter face image in the additional views to double check.

Do not be concerned by the filter color. The existing or replacement filter may be brown or blue.

Each spa has 1 x Purezone filter and 2 x pleated cartridge filters. 3 x pleated cartridges can be used

    Really great product .Water stays clear much longer. Use this with UV sanitiser and you do not need to add any more chemicals other than water Hardener and Shock . This is a great system for people with skin allergies
