The WaterCare EPM Series filter cartridges effectively reduce unwanted colours, tastes, and odours, including chlorine taste & odour, from your water. They are designed to achieve clean tasting water without easily being clogged. The carbon block's high porosity helps prevent the cartridge from clogging before its capacity is exhausted, maximising the life of the carbon block while maintaining a low pressure drop through the filter. Though these filters have a nominal micron rating, it is advised not to use this filter as the only means of sediment filtration in your system. These cartridges are protected by a unique pre-filter, designed to significantly increase the life of the cartridge by trapping larger sediments that typically clog carbon block cartridges. Durable and Safe Specifications: Filter Micron Rating: 10 Micron Length: 20" (50.8 cm) Diameter: 4.57" (11.6 cm) Fits Standard 20" Big Blue (BB) Filter Housings These filters will not impart any taste, odour, or colour to the water when used within the recommended temperature.
