10″ Undersink Catalytic Carbon Water Filter | Advanced Contaminant Reduction

Price range: $59.00 through $140.00

Greenfield Water 10″ Undersink Catalytic Carbon Filter
features advanced catalytic carbon media designed to help reduce chlorine,
chloramines, unpleasant tastes and odors, and selected organic contaminants
in household drinking water.

Made in Germany, this specialty filter combines the adsorption
properties of activated carbon with enhanced catalytic activity for
additional water treatment applications.

Designed for compatible 10″ undersink filter housings,
this replacement cartridge provides targeted filtration directly
at the point of use, where drinking and cooking water is needed most.

IMPORTANT: FILTER COMPATIBILITY

This listing is for one 10″ undersink catalytic carbon
replacement cartridge
. The housing is not included.

Please confirm compatibility with your existing undersink
filtration system before ordering.

This filter is not intended for gravity filtration systems
or larger 10″ Big Blue housings.

Key Features & Benefits
  • Advanced catalytic carbon: Combines adsorption and catalytic treatment properties.
  • Chlorine reduction: Helps improve the taste and odor of drinking water.
  • Chloramine treatment: Catalytic carbon is commonly used to reduce chloramines under suitable conditions.
  • Selected organic contaminants: May help reduce certain organic compounds and disinfection byproducts.
  • Hydrogen sulfide treatment: May help address sulfur-related odors when water chemistry and contact time are suitable.
  • Specialty filtration media: Original product literature references particulate filtration down to 1 micron; the finished cartridge rating should be confirmed.
  • Point-of-use filtration: Designed for compatible undersink drinking water systems.
  • Made in Germany: Manufactured using specialized water treatment media.
How Catalytic Carbon Works

Catalytic carbon is a specialized form of activated carbon
that combines physical adsorption with enhanced catalytic activity.

Its porous structure provides surface area for adsorbing
certain dissolved organic compounds, while its catalytic
properties help facilitate chemical reactions involved
in treating chlorine and chloramines.

Compared with conventional activated carbon, catalytic carbon
can offer advantages for certain contaminants, particularly
chloramines, when used under appropriate conditions.

Actual performance depends on water chemistry, contaminant
concentration, flow rate, contact time, and cartridge design.

Contaminant Reduction Applications

Catalytic carbon is commonly used to address several
drinking water quality concerns, including:

  • Chlorine
  • Chloramines
  • Unpleasant tastes and odors
  • Selected organic contaminants
  • Certain disinfection byproducts, including some trihalomethanes
  • Hydrogen sulfide under suitable treatment conditions

The original media literature also discusses potential applications
involving arsenic compounds, chromium, copper, cyanide, fluoride,
lead, mercury, selenium, and other contaminants.

Important: These broader applications do not establish
verified reduction performance for this specific undersink cartridge.
Some contaminants require specialized media or additional
treatment stages.

For concerns involving arsenic, fluoride, lead, or other
health-related contaminants, we recommend selecting treatment
based on verified performance data and your water test results.

Installation & Replacement

This filter is designed for installation in a compatible
10″ undersink filtration housing.

Before replacing your cartridge, turn off the water supply
and relieve pressure according to your system instructions.
Remove the existing cartridge, inspect the housing and seal,
and install the replacement filter.

After installation, flush the filter according to the
applicable cartridge instructions and check for leaks.

Replacement frequency depends on water quality, household
consumption, flow rate, and contaminant loading.

For best results, follow your system’s recommended maintenance
schedule and verify performance through water testing when
addressing specific contaminants.

Custom Water Filtration Recommendations

Every water supply is different. At Greenfield Water Solutions,
we help customers select filtration options based on their
individual water quality concerns.

Municipal Water Customers: Send us your service
address or available water quality report. We can review
publicly available information and discuss suitable
filtration options.

Private Well Customers: Send us recent laboratory
water test results so we can better understand your water
chemistry and treatment needs.

If additional contaminants are present, we may recommend
a different cartridge or a combination of filtration stages.

Independent drinking water testing is available through
Tap Score Water Testing.
