Why a Viron QL Cartridge Filter

• Filtration is finer than sand or glass media, so the water polishes up better.
• No backwashing. Astralpool rates the Viron as saving between 8,000 and 20,000 litres of water a year against a media filter.
• Four large elements carry enough capacity that Astralpool rates most residential pools at one element clean per year.
• Non-corrosive injection moulded components, built for Australian conditions.
