The self-cleaning water filter utilizes mechanical filtration technology with a stainless steel net cartridge to clean all types of sediments from your water down to 90 microns (0.09 mm).
The self-cleaning feature allows you to get the most out of your cartridges by cleaning them every once in a while when they get dirty. In fact, your cartridges will last you 3 years instead of 3-6 months.
