Guardian Series
Whole House Water Filters

Crystal Quest Guardian Series Whole House Water Filter Systems are designed and manufactured for outstanding service and are ideal for treating a variety of different water problems, without having to spend a fortune. Utilizing the best filtration media and components, each of our systems outperform and outlast the competition.

Salt-Free Water Softener

Enjoy the benefits of soft water without the salt. 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 them. The water left behind won’t adhere to surfaces so you will see a reduction in scale build up.

Filtered 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. These media are designed to filter chlorine, chloramines, pesticides, and hundreds of other contaminants. 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. Install a whole house water filter system and have filtered water from every faucet, shower, and tub in the home.

Premium Coconut Shell GAC

Premium Coconut Shell Granular Activated Carbon is used as an absorbent for a wide variety of inorganic 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.

Catalytic Coconut Shell GAC

Catalytic Coconut Shell Granular Activated Carbon removes both chloramine and hydrogen sulfide from potable water. It is outstanding in volatile organic compound removal, taste and odor control, and operates more efficiently when compared to traditional activated carbons.

Eagle Redox Alloy® 6500

Designed specifically for removing or reducing chlorine and water-soluble heavy metals. It controls scale, bacteria, and algae, even in hot water. The process medium received International Certification and is certified by Standard 42. This medium is also in compliance with California’s Health and Safety Code Section 166875 (or commonly known as AB1953) and Vermont Act 193.
