Nature Works is a filter media made from virgin granulated glass, designed to replace silica sand in any standard filter available on the market and intended for both swimming-pool water filtration and industrial use. It is the only filtering medium for water treatment that provides maximum performance; reuse capacity; energy, water and chemical products savings; certified purity and total safety during installation. Thanks to its Anti-Compaction Technology, its smooth edges and its polyhedral morphology, it avoids the appearance of biofilm and chloramines. It does not need flocculants and minimizes the loss of load.
