Performance Water Filters

MultiPure's MP880 Water Filters also feature our solid carbon block technology and includes a specially developed arsenic adsorptive media that provides for the reduction of Arsenic V. The MultiPure MP880 Series Water Filters use replacement filter Model CB11As; filter life/capacity is approximately 600 gallons or 960 gallons with a capacity monitor.

Multi Pure Water Filters / Replacement Water Filters are easy to replace and all MultiPure Water Filters include hardware and materials needed for installation.

Water enters the MultiPure Water Filter through a graded density pre-filter, which acquires a positive molecular charge in a moving stream of water. Since most colloidal contaminants exhibit a negative charge in solution, the media fibers will electrokinetically adsorb charged colloidal particles too small for removal by mechanical straining. The media combines the technology of mechanical straining, for the removal and retention of solid and semi-solid contaminants that can cause premature clogging of the water filter, and electrokinetic adsorption for the reduction of colloidal contaminants down to the sub micron (0.5 micron) range. Then the water passes through the highly compacted MultiPure solid carbon block water filter that also is designed to mechanically filter particles down to sub micron size, including cyst. 

The highly compacted Multi Pure solid carbon block water filter media is a blend of selected activated carbons and other materials that reduce inorganics as well as organic compounds. Many carbons are selected with a high surface area and high retentivity characteristics. The formulation of the MultiPure CB11As water filter includes a specially developed arsenic adsorbtive media that is blended with the carbons. The materials are formed into a carbon block, which is densely compacted to enhance the kinetics of the Multi Pure water filter and provide performance that cannot be achieved with other filtration technologies. With the Multi-Pure CB11As carbon block water filter, the water contact time is longer and provides for greater adsorption of many different chemicals, pesticides, herbicides, certain heavy metals, and arsenic. 

Multi Pure solid carbon block water filters are exceptionally uniform and do not channel or allow bypass as conventional granular activated carbon water filters (GAC) are known to do. Unlike conventional water purification GAC water filters that become incubators of bacteria, the densely compacted Multi-Pure water filters eliminate this problem because there is no room for growth in the compressed carbon. 

Finally, the water passes through a post-filter, which provides integral strength to the carbon block section and prevents material degradation of the water filter. The threaded polypropylene end caps seal the solid carbon block water filter and assure the integrity of the seal between the water filter and the housing. 

Capacity ratings apply to the chemical adsorption capabilities of the carbon and specialized media. Filter life will vary in proportion to the amount of water used and the level of impurities in the water being processed. Claims of capacity aren't applicable to contaminants reduced by mechanical filtration because of broad variations in the quality and quantity of physical matter in the drinking water. The Multi-Pure solid carbon block water filter is engineered so that contaminants removed by mechanical filtration will cause the flow rate to decrease, and the water filter will clog. It is recommended that the water filter be replaced when the first of the following occurs: (a) annually; (b) the unit's rated capacity is reached; (c) the flow rate diminishes; (d) the water filter becomes saturated with bad tastes and odors.
