PurexTriton Inground Pool Sand Filter

The oldest and most popular method of filtration is sand. Sand filters share two things in common: 1) When in the filtration mode, water always flows from top to bottom; 2) They all have some sort of lateral or underdrain with slots to hold back sand while allowing clean, filtered water to pass through.

Cleaning of the media, or sand, is accomplished through reversing the flow through the filter, to the "waste" line. This is known as backwashing.


PurexTriton Filters, the original and still the industry standard, ensure the utmost efficiency for sparkling water and easy operation.

The patented GlasLok process creates a one-piece fiberglass reinforced tank with a UV resistant surface finish for unequaled strength and durability. Swing away diffuser allows instant access to sand and all internal parts.

PurexTriton sand filters are built in extremely durable fiberglass and thermoplastic material for non-corrosion. Full 1 year limited tank warranty.
