Water Travels Through 3 Stages of Filtration

  • Stage 1  - Water flows through two 2 types of coconut shell Granulated Activated Carbons (Premium & Catalytic GAC). These are meant to reduce contaminants such as heavy metals, i.e. lead & mercury, chlorine, chloramine, disinfection byproducts such as trihalomethanes (THMs), & inorganic products such as herbicides, pesticides, and petroleum/pharmaceutical by-products.
  • Stage 2  - The GAC is infused with our Eagle Redox Alloys® 6500 to prevent and reduce the potential growth of bacteria and algae.
  • Stage 3 - Water flows through a 10” Carbon Block cartridge that removes or reduces VOCs (like commercial/industrial solvents, cleaners, paints, & dyes) and leaves you with the cleanest tasting water.

*If present in the water

How to Determine Capacity 

Capacity is the amount of water your filter creates clean water for your home. An easier way to think of it is how many bathrooms you have.

  • 1,000,000 capacity equals 1-3 bathrooms
  • 1,500,000 capacity equals 2-4 bathrooms

Water Without Breaking the Bank

The tank holds a large amount of water filtration carbon media, increasing the overall performance and lifespan of the filter. When it comes time to replace the media, every 5-10 years, simply replace the media inside the tank. There is no additional plumbing required and no need to replace the entire tank. The system requires no electricity.

Benefits

It is a well-known fact that people should drink eight glasses of water a day to help maintain a healthy lifestyle. With Crystal Quest Whole House Water Filters, you get delicious, refreshing, safe, top-quality drinking water.

Crystal Quest Guardian Series Whole House Water Filters are engineered for maximum filtration and maximum performance with minimum maintenance.

Salt-Free Water Conditioner (Optional)

Water passes through an anti-scale media and without a brine solution there is no need to backwash. This process neutralizes the minerals instead of removing or reducing them, allowing water to flow freely through your system without sticking to your pipes, dishes, or you!  If you have a hardness level of 25 GPG or higher please speak with a water specialist for a recommendation.

Additional Product Options

  • 12 GPM UV Water Sterilizer: Specifically designed to meet the demanding microorganism control concern. These microorganisms can range from bacteria and viruses to algae and protozoa. A major advantage of UV treatment is that it is capable of disinfecting water faster than chlorine without cumbersome retention tanks and harmful chemicals to your drinking water.
  • Leak Detector Valve: Used to detect a water leak within a water filter system and shuts down the water supply to prevent flooding.
  • Vacuum Breaker: Recommended to be installed inline ahead of water filter systems as a precaution against the rare occurrence of negative pressure (a vacuum) in the water line which can cause damage to the filter tanks and housings.
  • Metered Valve: The systems come standard with a timer valve which runs the backwashing schedule on a set number of days. (For example, every 7 days). The metered valve will run the backwashing based on a set number of gallons. (For example, 3,000 gallons).
  • Oxidation System: Utilizes ozone for efficient water oxidation, improving water quality.
