Availability:Usually ships in 5-7 business days
Item #:CQE-US-00309
Filter capacity

With three filter cartridges arranged in a row like silos, the Crystal Quest 8 Stage Triple Under Sink Water Filter is a powerful undersink water filter that is mounted directly into your water supply and features its own attractive faucet. Possessing excellent filtration characteristics, this filter removes practically all commonly encountered contaminants, and is only exceeded in its effects by specialty filters (such as arsenic filters) or reverse osmosis systems.
Please note: by default, this filter comes with a saddle valve suitable for linking it into hard copper piping under a typical sink. Please note in the Comments box of your order form if you have flex tubing under your sink instead, since a T-valve must be substituted for the saddle valve in this case. The filter is made to fit standard connections and comes with all hardware to hook it up.

Size and mounting details

  • This filter needs plenty of room under the sink for installation, so be sure to measure the space available before ordering. The filter measures 15” long, 4” deep, and 10” high – though it needs to have 14” of space to give clearance for replacing cartridges.
  • Includes a faucet and either a saddle valve or a T-valve.
  • Provides a maximum flow of 0.5 gallons per minute; 20 psi minimum operating pressure, 60 psi is maximum operating pressure.
  • Filters water from 40 to 90 degrees Fahrenheit.

Performance of the Crystal Quest 8 Stage

  • The first cartridge of the Crystal Quest Triple sends the water through a sediment filter which thoroughly removes all particulate matter, including silt, sand, rust, and so on.
  • The second cartridge filters the water through a six-stage filter that includes 1 micron filter pads (remove particulates plus parasites like Giardia and cryptosporidium); Eagle REDOX 6500 and 9500 KDF filtration media that removes chlorine and heavy metals; ion exchange resin to “soften” the water by removing excess minerals and taking out more heavy metals; and granulated coconut shell carbon to take out a wide range of chemicals and organic compounds (VOCs, MTBEs, solvents, pesticides, fertilizers, benzene, and so on).
  • The third cartridge is a solid carbon cartridge which thoroughly scrubs the water of chemicals, including industrial solvents, VOCs, and hundreds of others, providing clean, fresh, pure water that is completely safe to drink.
  • The cartridge filters are replaceable, though they are changed at different intervals. The sediment filter can be rinsed up to 30 times; the 6-stage filter comes in 10,000, 20,000, and 30,000 gallon versions; and the solid carbon block lasts 12 to 18 months.
Other characteristics of the Crystal Quest Triple filter

  • Uses the latest filtration technology, backed by 30 years of Crystal Quest experience.
  • 30 day money-back satisfaction guarantee, plus 1 year limited manufacturer's warranty.
