Compact Whole House Filters

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:

Style A : Particulate filtration down to 5 microns. Removes sand, rust and other sediment to produce more aesthetically pleasing water. Especially applicable to wells.

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.

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. Warranty is for five years. The unit needs only periodic cartridge change. Usual life of the carbon filter cartridge is about one year on chlorinated city water. It uses the top quality MatriKX CTO-grade extruded carbon block cartridge. This is a carbon block 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 manufacture's brochure. Most users change the cartridge annually. The sediment filter, Style A, uses a high quality 5-micron wound string cartridge to trap suspended particulate. Its lifespan depends on the quality of the water, and it is changed when flow becomes noticeably slower. Cartridge replacement is easy. (Wrench included.)

The basic system consists of a double-sized “Big Blue” filter vessel, the cartridge, a mounting bracket kit, and a filter wrench.

Filter housing dimensions are 23.5" tall and 7.25" diameter at the top. When mounted on the bracket, the unit stands about 9” from the wall.

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.

For more information about flow rate capacity for these units, and for increased flow rate suggestions, read this short article.
