Carbon Hydro 20″ Slim Water Filter | Coconut Carbon & KDF 55

$117.99

Greenfield Water Carbon Hydro 20″ Slim Filter
combines premium coconut shell activated carbon
with KDF 55 filtration media to provide
effective chlorine reduction and additional
treatment of selected heavy metals.

Proudly made in the USA,
this advanced replacement cartridge
brings together two complementary
water treatment technologies
in one convenient filter.

The activated carbon helps reduce
chlorine, improve taste and odor,
and adsorb certain organic compounds,
while the KDF 55 media uses
an oxidation-reduction process
to help address chlorine
and selected dissolved metals.

Designed for compatible
20″ standard slimline filter housings,
Carbon Hydro offers a practical
filtration option for residential
and other compatible
water treatment applications.

Orders ship within 2 to 3 business days.

How Carbon & KDF 55 Work Together

Carbon Hydro combines
two complementary
filtration technologies
within one cartridge.

Coconut Shell Activated Carbon

Activated carbon
is widely used
in water filtration
because of its
highly porous structure
and extensive internal
surface area.

As water passes
through the carbon,
certain dissolved
compounds are retained
through adsorption.

Activated carbon
is particularly
effective for
chlorine reduction,
taste and odor
improvement, and
adsorption of
selected organic
compounds.

KDF 55 Media

KDF 55 is a
high-purity
copper-zinc
filtration medium
that uses an
oxidation-reduction
process, also
known as redox.

This process
can help reduce
chlorine and
certain dissolved
heavy metals,
depending on
water chemistry
and operating
conditions.

Together, the
two media provide
complementary
treatment mechanisms
for a broader
range of water
quality concerns
than carbon
alone may address.

Chlorine Reduction & Water Quality

Chlorine is commonly
used in municipal
water treatment
to control
microorganisms.

Residual chlorine
can contribute
to noticeable
taste and odor
in household water.

Carbon Hydro uses
both activated carbon
and KDF 55 media
to provide chlorine
reduction through
complementary
treatment processes.

The activated
carbon adsorbs
certain compounds
while KDF 55
uses redox
chemistry to
help reduce
chlorine.

This combination
is designed to
improve the
aesthetic quality
of treated water.

Actual chlorine
reduction depends
on the cartridge’s
tested performance,
flow rate,
incoming chlorine
concentration,
and operating
conditions.

Heavy Metal Reduction with KDF 55

KDF 55 is a
specialized
copper-zinc
filtration medium
used in certain
water treatment
applications.

Through oxidation-reduction
reactions, KDF media
can help address
selected dissolved
metals under
appropriate conditions.

Potential treatment
applications include
certain forms of:

  • Lead
  • Mercury
  • Other selected dissolved metals

The effectiveness
of metal reduction
depends on
the specific
contaminant,
its chemical form,
water pH,
flow rate,
and cartridge
configuration.

Important:
The presence
of KDF 55 media
does not establish
a certified reduction
percentage for
every heavy metal.

For a specific
contaminant concern,
refer to verified
performance data
for the complete
cartridge.

Filtration Rating & Cartridge Construction

Carbon Hydro
features a
combination of
activated carbon
and KDF 55
filtration media.

The original
product specifications
reference
5 and 10 micron
filtration ratings
.

Micron ratings
describe the
intended particulate
filtration characteristics
of a filter.

The exact rating
and particle retention
performance depend
on the cartridge
construction and
rating method.

In addition
to particulate
filtration,
the carbon
and KDF media
provide chemical
treatment functions
that are separate
from the micron rating.

A micron rating
alone does not
establish removal
of dissolved
contaminants
or microorganisms.

Certifications & Product Standards

The original
Carbon Hydro
product information
references the
following standards
and compliance
attributes:

  • NSF/ANSI 42 for chlorine reduction
  • California Proposition 65 compliance
  • Lead-free certification

Important:
Certification scope
can vary by
component, cartridge,
model, and
specific performance
claim.

NSF/ANSI 42
addresses certain
aesthetic effects
such as chlorine
taste and odor.

It does not
automatically
establish certified
heavy metal reduction
or certification
of an entire
filtration system.

Please contact
our team for
documentation
confirming the
applicable certifications
for your specific
cartridge.

Installation & Replacement

Carbon Hydro
is designed
for installation
in compatible
20″ slimline
filter housings.

When replacing
your cartridge,
follow the
instructions
for your existing
housing and
filtration system.

General Replacement Guidance:

  1. Shut off the water supply.
  2. Relieve pressure according to the housing instructions.
  3. Carefully open the filter housing.
  4. Remove the used cartridge.
  5. Inspect and clean the housing as directed.
  6. Install the compatible replacement cartridge.
  7. Reassemble the housing and restore water flow.
  8. Flush the cartridge according to its instructions.
  9. Check for leaks before normal operation.

Replacement frequency
depends on incoming
water quality,
usage, flow rate,
and contaminant
loading.

Follow the
applicable cartridge
maintenance guidance
for your system.

Temperature & Application Considerations

The original
Carbon Hydro
product description
references the
ability of the
filtration media
to address certain
contaminants in
hot water applications.

However, the
maximum operating
temperature of
the complete
cartridge and
housing must
be confirmed
before installation.

Do not install
the cartridge
on a hot water
line unless
both the cartridge
and housing
are specifically
rated for that
application.

The presence
of KDF 55 media
alone does not
establish hot
water compatibility
for the complete
filter assembly.

Important Filtration Considerations

Carbon Hydro
is designed
to reduce chlorine
and selected
additional
contaminants
through activated
carbon and
KDF 55 media.

It is not
a universal
contaminant
removal filter.

The cartridge
should not
be relied upon
to remove
fluoride, nitrates,
arsenic,
microorganisms,
or other
contaminants
without specific
verified performance
data.

It is not
intended to
make microbiologically
unsafe water
safe to drink
without appropriate
treatment.

For households
with specific
water quality
concerns, water
testing can
help determine
whether additional
filtration is
necessary.
