It is available in 1.5 cubic foot and 2.0 cubic foot media configurations, with listed capacities of 1,000,000 or 1,500,000 gallons depending on the selected size. The Guardian uses a three-stage process with premium and catalytic coconut shell granular activated carbon, Eagle Redox Alloy 6500 media, and a replaceable 5\" × 10\" carbon block cartridge. It is designed for residential whole-house use, with service flow ratings of 9-11 GPM for the 1.5 cubic foot system and 10-13 GPM for the 2.0 cubic foot system. Buyers can choose the standalone Guardian filter or add the optional salt-free conditioner for scale-control support without a brine solution.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWhole-Home Filtration for Everyday Water Use\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Guardian system is designed to filter water at the main line before it reaches faucets, showers, laundry, and household fixtures. This makes it a practical fit for homes that want centralized filtration instead of relying only on point-of-use filters.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eThree-Stage Carbon-Based Filtration Process\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eWater travels through premium and catalytic granular activated carbon, Eagle Redox Alloy 6500 media, and a 10\" carbon block cartridge. This staged design supports reduction of listed contaminants when present in the water, including chlorine, chloramine, heavy metals such as lead and mercury, VOCs, herbicides, pesticides, and petroleum or pharmaceutical by-products.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTwo Capacity Options for Different Home Sizes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe 1.5 cubic foot Guardian system is listed for 1-3 bathrooms and 9-11 GPM service flow, while the 2.0 cubic foot version is listed for 2-4 bathrooms and 10-13 GPM service flow. This gives homeowners a manufacturer-listed bathroom-count guide for choosing between the two capacity options.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eOptional Salt-Free Conditioner Upgrade\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe Guardian can be ordered as a standalone whole house water filter or with an optional salt-free conditioner. The conditioner uses anti-scale media and does not use a brine solution, making it a separate upgrade for customers who want filtration plus scale-control support. If water hardness is 25 GPG or higher, Crystal Quest recommends speaking with a water specialist.\u003c\/p\u003e\n\u003c!-- Responsive Image\/Text Blocks --\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; padding: 0;\"\u003e\n\u003cdiv style=\"flex: 1 1 300px; max-width: 50%; padding: 0 4px;\" class=\"responsive-half\"\u003e\u003cimg decoding=\"async\" loading=\"lazy\" style=\"width: 100%; height: auto;\" class=\"responsive-image\" alt=\"Crystal Quest Guardian whole house water filter fiberglass tank system\" width=\"1000\" height=\"1000\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0761\/5781\/2888\/files\/GWH1.webp?v=1777335507\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 300px; max-width: 50%; padding: 1rem; text-align: center;\" class=\"responsive-half\"\u003e\n\u003cp\u003eThe Guardian is built for homeowners who want a filtration system with manufacturer-listed 1,000,000 or 1,500,000 gallon capacity options.
