Arsenic 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 Arsenic Removal Under Sink Water Filter System is dependable and built to last for years and effectively removes Arsenic from the water.

  • Multistage provides (1-3 years/10,000 gallons)* of quality safe and pure water.
  • All Crystal Quest® GAC is a mixed blend of coconut shell and catalytic GAC to address both chlorine, chloramines and these byproducts.
  • Easy to use and install on all standard sinks.
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.

Arsenic Removal Water Filter Cartridge

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.

Carbon Block Water Filter Cartridge

Water travels through a 5-micron solid carbon cartridge for removing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents and traps particles larger than 5 microns including sediment, silt, sand, and dirt.
