An outstanding water filter value, designed for treated municipal water supplies - provides excellent filtration of up to 2500 gallons at an affordable price. All components and component parts of this Under Counter Water Filter system are NSF certified for safe water filtration usage. Outstanding performance is achieved by using a replaceable Solid Carbon Block filter cartridge. These cartridges remove particulates as small as 1.0 micron and filter Fluoride, Chlorine taste and odor, Lead, VOC's, Cysts, sediment, rust, and particulate matter for sweet, clear, great-tasting water. We supply a designer ceramic-disk non-leak faucet in your choice of finishes.

Comes with one of these long-lasting replaceable water filter cartridges (pre-installed), our WR001 or the WRFLAR cartridge, this is the Optional Chlorine, Fluoride, Chloramine, Lead, Pathogens, Arsenic and more cartridge,(An incredible filter cartridge, the best specs of any cartridge we've ever found!). Provides 1,000 to  2,500 Gallons of great-tasting, crystal clear water depending on filter cartridge selected. That`s about 3 cents/gallon without lugging bottles around! We recommend annual replacement of the water filter cartridge.

Superior Under Sink Water Filter Details and Benefits

Our Superior series water filters provide =99.984% reduction of 3 - 4 m particles (=99.96% reduction of 1 -2 m particles) and operate as well as high performance contaminant reduction filters with extended life. The Superior series provides excellent reduction of Chlorine, tastes and odors. 

Design Features: Our Solid Carbon Block filters are designed flow in the radial (outside-to-inside) direction, providing increased dirt capacity and low pressure drop. Unlike granular activated carbon (GAC) water filters, solid carbon block filter cartridges will not channel or bypass and lose filtering capability and efficiency. Service life of the water filter cartridge is greatly extended by two layers of pre-filtration media consisting of a 15 m polypropylene spunbonded outer prefiltration layer and a 5m polypropylene melt-blown inner layer.

Comes complete with mounting bracket, stainless steel screws, chrome ceramic-disk non-leak faucet, feed water in-line valve and all necessary tubing.

1 year warranty on parts.

Customer Reviews
One of our best decisions.
  We are very happy with our new filter. From the friendly & helpful customer service, to shipping time, to the actual product & install, everything was first-rate. The only little snag we experienced was having to purchase a different size fitting for the water line connection under the sink; only a minor inconvenience. We love the way the water tastes, and the look of the little tap, and of course we are relieved to know we are getting much safer water. Thank you!

Great customer service
  This is our second filter from BestFilters. Our first was the counter filter just like this one, but when we changed kitchen faucets, we had to move our filter to under the counter. We had a problem with installing, and BestFilters helped us through it. Our product arrived very quickly, too.

Easy to install and maintain.
  I bought one of these last year and I liked it so much, I got one for may parents. It's easy to install and easy to replace the filter.
