"If a '10 star' rating was possible, this seller would receive that from me. Order arrived very quickly, was packaged properly and I enjoyed some great communication with the seller. Wouldn't hesitate at all doing business with this seller again for a filter replacement or new water filter system. It's obvious seller cares about people and strives to maintain business integrity!"

Under Sink Water Filter - Single-Stage

undercounter water filters A great water filter value, designed for chlorine treated municipal water supplies - provides excellent filtration of up to 2500 gallons at an affordable price. All components of the Under Counter Superior Water Filter system are NSF certified for safe water filtration usage. Outstanding performance is achieved by using a replaceable 1.0 micron Matrikx Pb-1 Solid Carbon Block filter cartridge. This cartridge removes particulates as small as 1.0 micron and filters 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 faucet which relieves the water pressure when the faucet is not on to help preserve housing life.

The long lasting replaceable water filter cartridge (pre-installed), our WR001 ($24.88. Follow this link for a further description of this replacement cartridge and its' capabilities ) provides 2,500 Gallons (about a year at 7 gallons per day!) of great- tasting, crystal clear water. 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 high performance sediment filters with extended life. In addition, the Superior series provides excellent reduction of Chlorine, tastes and odors. Graded-density prefiltration combined with a high dirt capacity extruded activated carbon serve to provide several times greater dirt life than molded water filter products.

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 prefiltration 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 faucet, feed water in-line valve and all necessary tubing.

1 year warranty on parts.

Customer Reviews
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.
