Use code "wten" and save 10% off all water filter purchases!
Utilizing 7 stages of water filtration, the Under Counter Twin Superior Water Filter is a great value. Designed for maximum effectiveness on chlorine-treated city water supplies it combines excellent filtration at an affordable price. Assembled in our facility from NSF Approved, American-made components for proven effectiveness and safety. 

Efficiently filters and reduces Chlorine taste and odor, Lead, Cryptosporidium, Giardia, VOC's, Fertilizers, Pesticides, Pharmaceuticals, rust, sediment, and particulate matter with all the benefits of a KDF/GAC (Granular Activated Carbon) filter cartridge followed by a Matrikx Pb-1 solid carbon block replaceable filter. Outstanding performance is achieved by the replaceable 0.5 micron Matrikx Pb-1 Solid Carbon Block filter cartridge. This cartridge removes particulates as small as 1.0 micron (a human hair is 70 microns in diameter) and effectively filters chlorine taste and odor, sediment, rust, and particulate matter for sweet, clear, great-tasting water.

These two long-lasting replaceable filters are pre-installed, and includes a premium, 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 2 cents/gallon without lugging heavy water bottles around! And you save hundreds of dollars per year over buying water!

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 both filters).

Incredibly, if a mere 10% of North America's plastic 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 Plastic (#1)--equal to 1.5 million barrels of crude oil

Filter Review
The filter system arrived earlier than promised. I didn't install it, but the person who did seemed to have no trouble. My main reason for buying this device was to overcome the really strong chlorine smell and taste that the tap water here has. A Britta pitcher had made little difference. The filter definitely eliminated the chlorine problem, but another mineral taste (calcium?) remained. Running the filtered water through the Britta seems to have corrected that. The flavor of the water is now neutral. A previous single filter under counter device (whose name I can't recall) actually delivered water with a very good taste. I don't know how it would have done on this really terrible tap water in my apartment.

Undersink Two Stage Filter Water System
This is the best two stage water filter system that I have ever owned! The installation was easy. The quality of the parts that came with the system are all first class! I chose the brushed nickel faucet and it is of the highest quality and looks great! Water flow is the best I have ever seen on a two stage system and the water taste is excellent. This company cares about it's customer's after the sell and I will say that has just added a new customer for all my filter needs!

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.

Water filter arrived quickly. Very robust containers with filters already installed and everything clearly marked. Instal was easy. Only addition I can think of would be a pressure relief button. Have not changed out filters yet so not sure if needed but some other manufactures have that feature.

Installs easily, functions perfectly! Water is a wonderful human right ! Pure water is up to us.
My Title really says it all. Obviously any plumbing task is not simple for anyone. If youer mwchanically inlined and able and willing to run to the hardware store to get additional parts (to remove the prayer unit for instance, and plug the sink outlet, which is NOT what you hook the water filter too). Also for me, location of the filter is crucial, I only chance filters about once a year, so turning off the water and emptying the cabinet is not a big deal, compared to having to look at the filter housing blocking usable space in the front of the cabinet. Best Filter products and service have kept me well stocked and satisfied for over a decade in two states. Thanks for the great customer service.

Undercounter filter
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.
