3m Water filtration system

Fine enough to remove bacteria and cysts, which are typically 1-2 micron in size. The naked eye can see down to about 40 microns. 0.2 micron filtration is frequently used in research labs to ensure removal of bacteria.With full-flow technology, no dedicated faucet is needed. This is a unique feature among high-performance filtration systems. The XL7000 can be installed directly into the cold water line supplying a sink, thus filtering all the cold water to the tap. Ideal for all food prep, fruit and vegetable washing, rapid fill of pots and coffee makers etc.Theoretically yes, but keep in mind most water used for washing is hot. A typical family of four uses about 3500 gallons of cold water at their kitchen sink in one year. The XL7000 is NSF-certified for 6000 gallons, and it's recommended to replace it once a year in any case.
