Removing scale, chlorine, taste & odour from your home water supply is essential to creating an enjoyable drinking experience from your tap and fridge, the SPECTRUM Carbon Inline Fridge Filter achieves this while providing savings compared to regularly purchasing bottled water. Scale build up occurs in non-filtrated household appliances due to the presence of calcium in the water supply, this filter combats this by using food grade phosphate to inhibit scale formation. This replacement cartridge for your fridge or the AS2 System has a simple inline installation and takes water from the mains supply and improves the taste whilst reducing chlorine and chemical contaminant prior to delivery from the dedicated tap. Thanks to the push-fit connectors filter change out is an easy process that requires little effort, simply apply pressure on the connector and pull the tubing out. This filter cartridge requires replacing after a recommended 6 months.
