Efficient, inexpensive whole house cartridge filters for sediment and chlorine/chemical reduction.

Our compact series cartridge-style point-of-entry systems are highly effective, easily maintained units designed to filter all water entering homes, small businesses, and restaurants.

They come in the following three styles:

  • Sediment Filtration (Style A) : Particulate filtration down to 5 microns. Removes sand, rust and other sediment to produce more aesthetically pleasing water. Especially applicable to wells. Uses a high quality 5-micron wound string cartridge.

  • Carbon Block Filtration (Style B) : Carbon block filtration down to nominal 5 microns. Removes chlorine and general chemical contaminants while providing clearer, better tasting water. Most often used on chlorinated city water.

    It uses the top quality MatriKX CTO extruded carbon block cartridge, with eight times the filtration capacity of a drinking-water size cartridge. It provides long-term dechlorination of ordinary city tap water. For more information see the manufacturer's brochure.

  • Sediment and Carbon Block Filtration (Style C) : A double system that consists of one of each, Style A followed by Style B. This provides protection for the carbon cartridge from premature failure due to sediment blockage in high-sediment areas. It can be used on either city water systems or wells.

These are simple units that last indefinitely if protected from weather, needing only periodic cartridge change. The typical life of a carbon filter cartridge is about one year on chlorinated city water. A sediment filter's lifespan depends on the quality of the water, and it is changed when flow becomes noticeably slower. For both cartridges, replacement is easy with the included wrench.

Please specify 1" or 1.5" port size. You can write it into the “Comments” section of the shopping cart. If no preference is stated, 1" will be shipped.
