Under Sink Water Filter - Two-Stage - by BestFilters with Ceramic Disk Faucet

under sink water filters The Under Counter Twin Superior Water Filter is a great value. Designed for maximum effectiveness on chlorine-treated water supplies it combines excellent filtration and an affordable price.

Effectively filters and reduces Chlorine taste and odor, Lead, Cryptosporidium, Giardia, VOC's, fertilizers, pesticides, rust, sediment, and particulate matter with all the benefits of KDF/GAC (Granular Activated Carbon) and a Matrikx Pb-1 solid carbon block replaceable filter. Outstanding performance is achieved by the 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, sediment, rust, and particulate matter for sweet, clear, great-tasting water.

These two long-lasting replaceable filters are included, as well as, a drip-proof designer ceramic-disk faucet. The filters provide 2,500 Gallons (about a year at 7 gallons per day!) of great-tasting, crystal clear water. That`s less than 5 cents/gallon without lugging heavy bottles around! Save hundreds of dollars per year!

The long lasting replaceable water filter cartridges (pre-installed), our #WR001 ($24.88), in combination with our # WR024 ($24.88) provides 2,500 Gallons (about a year at 7 gallons per day!) of great- tasting, crystal clear water. That`s about 2 cents/gallon without lugging bottles around! We recommend annual replacement of the water filter cartridges. Order filter replacement set WR004 (Contains 1 - WR001 and 1 - WR024).

Superior Under Sink Water Filter Details and Benefits

We recommend annual replacement of the filters. Order filter replacement set WR004 (Contains 1 - WR001 and 1 - WR024).

Stage 1:
The filter cartridge in the 1st stage of the WU002 twin systems utilizes KDF filtration media, GAC (granular activated carbon) and 3 stages of polypropylene sediment filtration. KDF Process Media are high-purity, granulated copper and zinc-based alloys that treat water through a process based upon the principle of redox (Oxidation-Reduction). Originally, KDF was shorthand for Kinetic Degradation Fluxion. We can explain redox like this: KDF Fluid Treatment’s unique combination of copper and zinc creates an electro-chemical reaction. During this reaction, electrons are transferred between molecules, and new elements are created. Some harmful contaminants are changed into harmless components. 

Stage 2: The filter cartridge in the 2nd stage of the WU002 is a high capacity 1 micron carbon block filter, our WR001.Contaminant Reduction: This solid carbon block filter provides 0.5 micron nominal filtrations (1 micron absolute). A dense prefiltration wrap combined with a high capacity extruded activated carbon block serves to provide excellent filtration characteristics with a high affinity for adsorption of Chlorine tastes and odors, Lead, Cysts, dirt, rust and sediment.

Includes all necessary parts and instructions for easy installation.

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

Limited 1 year warranty on parts.

       Incredibly, if a mere ten percent of North America's bottled water intake were reduced by switching to home-filtered water in reusable containers, we could eliminate:
  • 133,000 trucks driving an average of 500 miles--saving nearly 12 million gallons of diesel fuel
  • Over 100 million pounds of greenhouse gasses--equal to taking 1,100 cars off the road annually
  • 213 million pounds of PET--equal to 1.5 million barrels of crude oil or improving the PET recycling rate by 10%

Under Sink Two Stage Water Filter System
  Easy installation, no leaks. Water tastes great! Recommended!
  Reviewed by:  Andrew from South Bend, IN. on 12/7/2013
Great filters for the price.
  Been using an expensive RO system for years and just moved into another home. RO being a water waster we wanted a different more environmentally friendly filter. Was easy to install. For a few days water tasted funny even after flushing the filter, but this went away by day 3. Coming from RO water I can taste the minerals that are now still there, but all of the nasty chlorine taste is gone. I like it better than the RO water now. More thirst quenching water.

  The unit looks attractive, and the water tastes amazing! Very happy with the customer service as well. Ordered an additional filter for the fridge which was the wrong item (our mistake), and the return and refund was handled courteously and promptly.
