Inline Carbon Polishing Replacement Filter | Undersink Systems

• Additional carbon filtration:
  Provides a final activated
  carbon treatment stage
  after your existing
  undersink system.
• Chlorine reduction:
  Designed to reduce residual
  chlorine and associated
  taste and odor.
• Improved water taste:
  Helps address certain
  compounds that may
  affect the taste
  and smell of water.
• Organic compound adsorption:
  Granular activated carbon
  can adsorb certain
  volatile organic compounds
  and other organic chemicals.
• Additional treatment of
  chlorination byproducts:
  Activated carbon may reduce
  certain trihalomethanes
  under appropriate
  operating conditions.
• Convenient replacement:
  Designed for use in
  an existing compatible
  inline polishing
  filter housing.
• Routine maintenance:
  Typical replacement
  interval of approximately
  6 to 12 months,
  depending on water
  quality and usage.

Granular activated carbon,
commonly called GAC,
is widely used in
water treatment because
of its highly porous
structure and extensive
internal surface area.

As water passes through
the carbon media,
certain dissolved
compounds are attracted
to and retained
on the carbon’s
internal surfaces
through a process
called adsorption.

Activated carbon
is particularly useful
for addressing chlorine,
taste and odor concerns,
and selected organic
compounds.

The effectiveness
of carbon filtration
depends on several
factors, including
the specific carbon
media, contact time,
flow rate, and
incoming water chemistry.

The inline polishing
filter is intended
to complement the
existing filtration
stages rather than
replace them.

Chlorine is commonly
used by municipal
water utilities
to disinfect
drinking water.

Although chlorine
serves an important
purpose in water
treatment, residual
chlorine can contribute
to noticeable taste
and odor.

The granular activated
carbon in this
replacement cartridge
is designed to provide
additional chlorine
reduction after your
existing undersink
filtration system.

This additional
treatment stage
can help improve
the aesthetic
quality of water
at the point
of use.

Performance Note:
The original product
description references
chlorine reduction
exceeding 95%.
Specific reduction
percentages depend
on the cartridge’s
tested performance
and operating conditions.

For a verified
reduction percentage,
refer to applicable
laboratory testing
for the exact
replacement cartridge.

Activated carbon
can adsorb a range
of organic compounds
depending on their
chemical properties
and the filtration
conditions.

Potential treatment
applications include
certain:

• Volatile organic compounds (VOCs)
• Trihalomethanes (THMs)
• Pesticides and herbicides
• Other organic compounds that are adsorbable by activated carbon

Not every compound
is reduced equally,
and performance
varies according
to carbon type,
contact time,
contaminant concentration,
and cartridge capacity.

Important:
This polishing cartridge
should not be relied
upon for lead, mercury,
fluoride, arsenic,
or other specialized
contaminant reduction
without verified
performance data
for the specific
cartridge.

For those concerns,
the appropriate
contaminant reduction
stages in your
primary undersink
filtration system
remain essential.

This replacement
cartridge is intended
for compatible
inline carbon polishing
filter housings
installed downstream
of Greenfield
undersink systems.

It may be installed
after or above
the primary
undersink filtration
assembly, depending
on the original
plumbing configuration.

What’s Included:

• One replacement granular activated carbon filter

Not Included:

• External inline filter housing
• Complete undersink filtration system
• Additional replacement cartridges
• New installation plumbing components

Replacement should
be performed according
to the instructions
for your existing
housing and system.

If you’re unsure
whether this cartridge
fits your housing,
please contact
our team before
ordering.

Routine replacement
helps maintain
the intended
performance of
your inline carbon
polishing stage.

For many residential
applications,
replacement is
recommended approximately
every 6 to 12 months,
depending on water
quality and usage.

Actual cartridge
life may vary
according to:

• Incoming chlorine concentration
• Water consumption
• Flow rate
• Organic contaminant levels
• Carbon adsorption capacity
• Operating conditions

Carbon adsorption
capacity is finite,
so cartridges
should be replaced
according to the
appropriate maintenance
schedule rather than
waiting for a noticeable
change in water taste.

When replacing
your cartridge,
follow the housing
manufacturer’s
instructions for
shutting off water,
relieving pressure,
replacing the filter,
and flushing
the system.

This inline polishing
filter provides
an additional
granular activated
carbon treatment
stage.

It is not intended
to replace the
primary contaminant
reduction filters
within your
undersink system.

The polishing
cartridge should
not be considered
a standalone
solution for
microbiologically
unsafe water
or contaminants
requiring specialized
treatment.

Actual contaminant
reduction performance
depends on the
specific cartridge,
water chemistry,
flow rate, and
operating conditions.

this replacement
filter is compatible
with your existing
inline polishing
housing?

to help confirm
compatibility and
identify the
appropriate replacement.
