The external UltraWater filter uses the technology created by AlkaViva to thoroughly clean the water of the harder chemicals, even pharmaceuticals. Read more about UltraWater filtration.
UltraWater filters are not recommended for use in high-sediment areas unless you have a good sediment filter before it. The pores are very tiny and can clog up if the water is too full of any sort of sediment.
Change filters at least yearly.
