Crystal Quest SMART Ultra Filter Cartridges

Overview

The Crystal Quest SMART Ultra Filter Cartridges use advanced multi-stage filtration technology to provide enhanced contaminant reduction and increased service life within the Crystal Quest SMART cartridge range. Designed for commercial and industrial water treatment applications, they deliver higher filtration capacity while helping protect downstream equipment and reverse osmosis membranes.

Each SMART Ultra cartridge combines multiple filtration media within a single cartridge, including coconut shell granular activated carbon, catalytic carbon, ion exchange resin, and Eagle Redox Alloy® media. This layered design helps reduce chlorine, heavy metals, volatile organic compounds (VOCs), odors, and other impurities commonly found in water supplies.

SMART Ultra cartridges are suitable for use in Crystal Quest filtration and reverse osmosis pre-treatment systems where enhanced contaminant reduction, increased filtration capacity, and reliable membrane protection are required.

SMART Ultra cartridges provide increased filtration capacity and extended service life compared with SMART Plus cartridges, making them well suited for commercial and industrial applications requiring longer maintenance intervals and dependable long-term performance.

Compatibility

SMART Ultra cartridges are available in multiple sizes for use with compatible Crystal Quest filtration and reverse osmosis systems.

Please select the cartridge size that matches your existing filter housing or system specification.

Where a specific cartridge is required for a Crystal Quest system, refer to the product documentation or replacement cartridge information provided for that system.

Replacement Guidance

Replacement frequency depends on feed water quality, system usage, contaminant levels, and operating conditions.

Regular cartridge replacement helps maintain filtration performance and protect downstream components, particularly reverse osmosis membranes.

Application

SMART Ultra cartridges are commonly used as pre-filtration components in reverse osmosis and water treatment systems to help reduce contaminants before water reaches downstream filtration stages.

By reducing chlorine, heavy metals, organic compounds, and other impurities, the cartridges help support improved water quality, system efficiency, and equipment longevity.
