Replacement Parts and Accessories
We recommend the pre- and post-filters on your Sierra system be changed every 6-12 months. The membrane cartridge should be changed every 12 months. This ensures that you will have consistently high-quality drinking water. Depending on the characteristics of your local tap water, you may need to change the filters earlier or later. The best way to determine when to change the membrane cartridge is to test your water with the HM Digital TDS Water Quality Tester. We recommend the membrane cartridge be changed whenever the TDS reduction drops below 85%.
