Ceramic Under Sink Water Filter System

Description


Benefits

Recommended Leak Detector/Flood-Prevention Valve : Due to numerous unpredictable circumstances including installation errors, flood damage is subject to occur without a leak-detector valve. Our recommended leak detector/flood-prevention valve will allow the water system to be flood-proof.

Our Ceramic Under Sink Water Filter is dependable and built to last for years and effectively removes harmful bacteria, sediment and many other contaminants from water.

  • Easy to use and install on all standard sinks
  • Ceramic Water filter Cartridge that is able to be cleaned up to 30 times
Please note: When considering installation, if current under sink plumbing is hard copper tubing the saddle valve would be used; for flex tubing, the T-valve would be required. While ordering a prompt will require that an installation valve is specified in order to progress through the order entry screen.

Ceramic Water Filter Cartridge

Water travels through a ceramic cartridge and effectively removes harmful bacteria such as E. coli, Fecal coli form, Salmonella, Streptococcus, cysts (Cryptosporidium, Giardia) and sediment. Filtration as low as 0.5 microns. The cartridge can be cleaned up to 30 times (about once a month).

SMART Water Filter Cartridge

Water flows through our SMART special house blend of 2 types of coconut-shell GAC (including Catalytic) with 2 types of Eagle Redox Alloys® (9500 & 6500) & anion exchange resin. This blend effectively reduces & removes heavy metals, chlorine & chloramine, pesticides & herbicides, pharmaceutical by-products & other inorganic substances such as petroleum byproducts. Ceramic and Tourmaline balls to enhance the water and maintain a more alkaline pH. To read about how GAC's work, click here. To read about the ERA® Oxidation/Reduction Process, click here. 

Water flows through ion exchange resins, reducing heavy metals such as lead, copper, aluminum, and water hardness.

Water flows through granulated activated carbon (GAC). GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine, chemicals linked to cancer (THM's, benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water causing bad taste and odors in your drinking water.

All Crystal Quest® GAC is a mixed blend of coconut shell and catalytic GAC to address both chlorine, chloramines and these byproducts.
