One that moves away from using sand to something that’s 100% bio-resistant.

A system that’s trusted by Belfast Zoo’s Sea Lion pool.

After years of R&D on swimming pools and commercial pools, we now only use AFM®, the best performing filter media on the market with a certified 1-micron filtration rate.

With an impressive 50-60% reduction in water consumption (great for the environment!) AFM® is a sustainable product made of recycled glass.

Say goodbye to chlorine smells, bacteria and parasites with the world’s number one filter media.
