Quality Built To Last
Smart Control Head for Backwashing
Unlike traditional timing head that pre-set a backwashing schedule every few days, Crystal Quest digital control head pre-calculates the amount of water that is treated and backwash the tank based on the amount. This helps with remove particles and built up contaminants. In essence, backwashing helps reverse the flow of water while increasing its velocity. This separates the particles out of your clean water.
Customize to Fit Your Needs
Fully customizable settings allows you to control backwashing schedules to fit your needs
Easy Connection
Newly innovated quick connection allows you to easily connect tubing to the control valve. Simply plug cord from the control valve into 110V electrical outlet.
Premium Quality Tank
The tank is made from high quality fiber glass or stainless steel casting to last many years and corrosion resistant.
Easy Filter Replacements
Filters are engineered for quick, simple slide in and out cartridges.
High Velocity Upflow
Dual tank design increases water contact time with contaminants removing media to prevent clogging or media channeling.
High Water Pressure

Guardian Whole House Water Filter
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.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, & 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 VOCs (like commercial/industrial solvents, cleaners, paints, & dyes) and leaves you with the cleanest tasting water.
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.

Please Note:
- This unit is not a water softener. It may reduce some hardness but not all. If your water is very hard, please let us know
- Warning: Although a leak detector/flood-prevention valve is optional with your purchase, it is highly recommended to avoid property damage. Due to numerous unpredictable circumstances including installation errors, flood-damage is subject to occur without a leak-detector valve. Including a leak-detector will allow the water system to be flood-proof.
- This system is installed at the main water supply line in order to treat all the water in your home; unlike an RO system, this system will NOT reduce Total Dissolved Solids (TDS) and instead keeps healthy minerals in your water; if you are interested in a filter that removes TDS consider our Crystal Quest Reverse Osmosis (RO) systems
Additional Filters Purchased Separately
Water Softener (optional)
• For maximum effectiveness, we highly recommend installing this system before a water softener
• Hard water treatment- Water described as "hard" is high in dissolved minerals, specifically calcium and magnesium.
• Scale build up- You may see staining on your sinks, tubs, showers, and clothing. You may also notice less lather from your shampoos and soaps and even a feeling of film on your skin. All these are symptoms of the need for softened water.
• Protect your household appliances: The Crystal Quest water softer also inhibits the growth of scale. The filtered water helps to extend the lifespan of your plumbing system and the household appliances, such as washing machine, dishwasher, water heater, etc.
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, 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.
