The PWCTO-97520BB by Purewave is a high-quality carbon block activated carbon filter, designed for installation in Big Blue 20" x 4.5" filter housings.

The filter is made from compressed high-purity activated carbon derived from coconut shell, offering a large adsorption surface and high efficiency in improving water quality. Thanks to its Carbon Block structure:

• Effectively reduces free chlorine.
• Significantly improves the taste and odor of water.
• Retains fine suspended particles.
• Helps reduce organic compounds (VOC).
• Reduces pesticides and various organic contaminants.
• Limits the release of carbon particles during first use.

The filter’s full antimicrobial action helps protect the filtering media from the growth of microorganisms on its surface, keeping the filter clean throughout its useful life. (The antimicrobial property applies to the filter itself and does not constitute a claim of sterilization or disinfection of the water.)

The filter is suitable for:

• Home central water supply systems.
• Professional applications.
• Equipment protection.
• Pre-filtration for reverse osmosis systems.
• High-flow Big Blue applications.
