6 Silver Sentinel micro-filters 355 mm

These filters are also available individually.

The Silver Sentinel filters out much smaller particles than traditional filters - down to 1 micron instead of 30 microns - to give even clearer, more sparkling water.

Do not use flocculants such as 3-in-1 water clarifier with this filter, as they will shorten its life without providing any benefit for your spa water.

Like all micro-filters, "Silver Sentinel" filters are designed for a single use. They last for 6 to 12 weeks and should not be cleaned. They are made from polypropylene, and - once dry - can be recycled with other polypropylene materials.

You can replace a Silver Sentinel filter with a traditional-style filter cartridge, model Pleatco PWW50L / RD50.
