External Triple Housing for Pre-Filter Cartridge Available in U.S. and Canada (5 BV).
To hold the supplemental cartridges in place, a filter housing is needed. The housing includes all of the necessary fittings to connect to the water supply feeding your ionizer. Although the capacity of each filter inside the housing varies (see specific filter description pages), a typical filter housing itself is good for approximately 5 to 7 years.
