Crystal Quest Double 7 Stage undersink Fluoride Water Filter

Are you concerned about having Fluoride, Arsenic, Lead and other contaminants in your drinking water?

The Crystal Quest 7 stage under sink fluoride removal water filters will remove or reduce fluoride, lead, arsenic and hundreds of other contaminants from your drinking water.

This under sink water filter has 7 stages of filtration to remove hundreds of contaminants.

Water flows through a Fluoride removal cartridge containing a fine-mesh pre-resin media to remove or reduce fluoride; it also will remove or reduce lead and arsenic from your water.

Then there is a second 6 stage cartridge that has coconut shell carbon to remove chemical contaminants and chlorine, it also contains eagle redox 6500 & 9500 to remove or reduce heavy metals.

There is also an ion exchange resin media to remove or reduce more dissolved metals and water hardness. This cartridge has a pre and post 1 micron filter pad to remove un-dissolved matter also.

The 6 Stage Cartridge will filter for 10,000 gallons and the fluoride cartridge will filter for 1,000 to 1,500 gallons on average

The 1st stage water flows through a fluoride removal cartridge containing fine-mesh pre-resin media to reduce fluorides below 0.5 ppm. That contains synthetic aluminum oxide absorbent media, specifically designed to have a high affinity for fluoride, Lead and Arsenic. Read more on fluoride and lead removal media

2nd and 7th stage water flows through a pre and post one micron filter pads to remove suspended particles like silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt and any other un-dissolved matter.

3rd and 4th stage water flow through a eagle redox 6500 & 9500 media to remove or reduce chlorine and heavy metals like lead, mercury, copper, nickel, chromium, cadmium, aluminum and other dissolved metals. Read more about eagle redox 6500 & 9500

In stage 5 water flows through granulated coconut shell activated carbon to remove chlorine, (THM’s benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC’s) PCB’s, MTBE’s and hundreds of other chemical contaminants the might be in your drinking water causing bad taste and odors.

6th stage water flows through an ion exchange resins, to reduce or remove heavy metals like lead, copper, aluminum and water hardness. Read more about ion exchange resin

Benefits of the Crystal Quest double 7 stage under sink fluoride and lead water filter

• Dependable and built to last for years
• Easy to install
• Quick and easy to use
• Effectively removes fluoride, lead, arsenic and hundreds of contaminants
