Our filters are designed largely for Whole House or Business Premises usage. Located in proximity to the incoming mains water. For homes this filter will fit under kitchen sinks if the space permits ( 8 x 17”). They are designed for a 1-2 year life depending on the volume of water used.

Filtration of  mains water is easy to understand and treat.

Well Water varies in quality from site to site and season to season, so it requires a water analysis before designing a filtration system. See page on Well Water.
