CRYSTAL QUEST« Mega Countertop Water Filter system eliminates the impurities typically found in tap water to offer you great tasting and pure drinking water. It is also very attractive and  economical. This configuration provides eight stages of filtration to produce sparklingly clean water. It starts with an advanced sediment filter, then water flows through Crystal Quest 6 Stage Filtration system, and then final polishing is done with a solid state 5 micron carbon filter. This configuration is the most robust Crystal Quest countertop configuration which effectively removes hundreds of contaminants from water. The latest technologies are employed in the Crystal Quest Multi-Stage filter; combining the adsorption capabilities of coconut shell activated carbon with Eagle Redox Alloy«. This combination has been tested to boost filtration capacity to remarkable levels. 

Making Alkaline Water: After filtering your water with you CRYSTAL QUEST« Water Filter, use one of our Alkaline Booster Drops to make alkaline water.

CRYSTAL QUEST Options: you can get one of three different models of the CRYSTAL QUEST« Mega Countertop Water Filter system; with each of the 6-stage filters having a specified filtration capacity.

  • CRYSTAL QUEST« Mega Multi-Stage Plus filters up to 10,000 gallons (1-3 years) *

  • CRYSTAL QUEST« Mega Multi-Stage Ultra filters up to 20,000 gallons (2-4 years) *

  • CRYSTAL QUEST« Mega Multi-Stage Ultimate filters up to 30,000 gallons (3-5 years) *

The filter is designed to last between 1 - 3 years. You can tell when the filter needs changing because it will either stop working or slow to trickle. This unique water system is great for homes, apartments or office use.  

The Crystal Quest Mega filter is quick and easy to install. follow these simple instructions:

Check your thread type outside threads: no adapters needed Inside threads: select which adapter to use
  1. Remove aerator from your faucet on which the filter will be installed

  2. Determine the type of threads on your faucet. If your faucet has outside threads then no adapters should be needed.  If your faucet has inside threads then you will need to select the correct adapter and washer and screw then into the faucet and tighten manually. The adapters included with your Crystal Quest Mega filter will fit most faucets.

  3. Screw the diverter valve onto the faucet, turning swivel collar to tighten. Make certain that the gasket is positioned securely between the diverter valve and the faucet or adapter. Rotate diverter valve stem to desired position. The swivel color may need retightening.

  4. Turn on the water then turn the diverter handle to send water to the filter system.

CRYSTAL QUEST « Utilizing the latest technologies in water industry, coupled with 30 years of manufacturing expertise, we provide you with the most effective, healthy, great-tasting water, conveniently, at the most affordable price. Our products are attractive, easy to install and use, and removes more than 500 contaminants from water. The unique design allows for a substantial amount of filtration media enabling more contact time with the water. More contact time means better filtration.

Stage 1 - 5 Micron Sediment Filtration: water travels through a sediment filter cartridge that removes sediment, silt, sand and dirt. This helps the 6 Stage filter to function at its optimum longer extend the life of water filter. This is CRYSTAL QUEST's pleated cartridge. It out performs wound, spun, melt blown, resin bonded and other "depth" type filter elements because it is pleated to provide increased surface area and longer life.

Crystal Quest's 6 Stages of Filtration:

Stage 2: Water flows through pre and post one - micron filter pads (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other un-dissolved matter.

Stage 3 and 4, water flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc (Eagle Redox Alloy« 6500, and Eagle Redox Alloy« 9500.) Eagle Redox Alloy« is a major advancement in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (REDOX) principles. Chlorine is instantaneously and almost inexhaustibly oxidized. Tests on Eagle Redox Alloy«/GAC cartridge have shown 99+% chlorine removal even after 20,000 gallons of water passed through the filter. In comparison, carbon cartridges of comparable volumes drop below 90% effectiveness after only 4,000 gallons. This is an important consideration.

Iron and hydrogen sulfide are oxidized into insoluble matter and attach to the surface of the media. Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals are removed from the water by the electrochemical process. They are attracted to the surface of the media, much like a magnet. The media inhibits bacterial growth throughout the entire unit. In fact, it has been shown to be reduced up to 90%, eliminating the need for silver, which is commonly used in carbon-only filters (silver is considered a pesticide by the EPA and, as such, must be registered with them). Is copper or zinc added to the water in any significant amount? On 2.3 ppm chlorinated water, <0.05 mg/l copper and only 0.46 mg/l zinc were measured. The EPA aesthetic levels are 1.0 mg/l for copper and 5.0 mg/l for zinc. Both zinc and copper are essential minerals for good health - the FDA recommends a daily intake of 15 mg of zinc and 2 mg of copper.

Stage 5, water flows through ion exchange resins, reducing heavy metals such as lead, copper, aluminum, and water hardness.

Stage 6, 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 (99.9%), 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.

Carbon is extremely porous and provides a large surface area for contaminants to collect. Carbon-only filters must also use their capacity for chlorine removal, resulting in a shortened life. They also may use a bituminous coal carbon, which is good at removing chlorine, but not as effective at removing chemicals. We use a high-grade coconut shell carbon that is most effective at removing chemicals. Coconut shell carbon provides a significantly higher volume of micro-pores than either coal, wood or lignite based carbon. As a result, it is more effective than other carbon types in removing trihalomethanes (THM's) and other chemicals from municipally supplied water. Since our REDOX media removes the chlorine before it reaches the carbon, the carbon capacity is not wasted on chlorine and is free to concentrate more effectively on organic contaminants.

Stage 7, water flows through another one-micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or total elimination of a wide variety of contaminants.

Stage 8 - water travel through a solid carbon cartridge for removing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents.
