Multi-Pure MP750SB Stainless Steel Under Sink Water Filter

How the Filter Works:

Multi-Pure Drinking Water Systems’ replaceable triple-action filter has been formulated using materials that will provide the highest quality drinking water without removing the healthful, natural minerals. Multi-Pure's carbon block filters combine mechanical filtration, electrokinetic adsorption, and physical adsorption to provide the most effective contaminant reduction possible.

Mechanical Filtration: The filtration process begins with water passing through a graded density 5-micron pre-filter that traps dirt, sand, and particles that affect the taste, odor, and overall appearance of your water. Then the water passes through the highly compacted solid carbon block where direct mechanical interception of particles as small as 0.5 micron occurs. Asbestos, cysts, and turbidity are reduced through mechanical filtration at the sub-micron level.

Electrokinetic Adsorption: The graded density prefilter acquires a positive molecular charge as water passes through it. Since most colloidal contaminants exhibit a negative charge in solution, the media fibers will electrokinetically attract charged colloidal particles too small for removal by mechanical straining. 

Physical Adsorption: Multi-Pure’s highly compacted carbon block filter media is a blend of selected activated carbons and other materials that reduce aesthetic contaminants and health-related contaminants. Many carbons are selected with a high surface area and high retentivity characteristics. The materials are formed into a carbon block, which is densely compacted to provide longer contact time and outstanding performance that cannot be achieved with other filtration technologies. Multi-Pure’s carbon block filter effectively adsorbs contaminants with health significance, including chlordane, lead, mercury, MTBE, PCBs, Toxaphene, and VOCs, plus aesthetic contaminants such as chlorine and chloramine. 

The carbon block filter is engineered so that contaminants removed by mechanical filtration will cause the flow rate to decrease, and the filter will clog. It is recommended that the 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 filter becomes saturated with bad tastes and odors.

The effectiveness of any drinking water treatment device is measured by the performance of its filter. Multi-Pure provides the best in water filtration!
