Polypropylene Yarn 5/20 micron water filter cartridge
Filters' life expectancy is generally between 3-12 months. Water supply quality and frequency of use would be the main determining factor as to how long the filter will last. Should you notice severe discolouration and/or a noticable reduction in the water flow please replace the cartridge with a new one. On average it would be best to change the cartridge every 6 months.
