It has set the industry standard for effectiveness, efficiency, long runs between service, and providing years of dependable, low maintenance operation. Tritonî II Side Mount Filters feature a special internal design that keeps the sand bed level, ensuring even water flow, and resulting in the most efficient filtration possible.
Now Available with ClearPro Technology for 60% Cleaner Water Triton II Side Mount Filterss with ClearPro technology, remove particles up to five times smaller than traditional sand filters, well below what your eye can detect for water that truly sparkles with clarity. The ClearPro secret is a proprietary, porous tube that water must pass through before re-entering the pool. It creates a final barrier to the very smallest particles that sand cannot trap, including the finest dust particles, algae and pollens.
