Stainless Steel Countertop Replacement Filter Pack (2-Stage Legacy System)

• Continued system support:
  Compatible replacement filtration
  for existing Greenfield countertop
  systems.
• Premium American made filtration:
  Features an advanced carbon block
  manufactured in the United States.
• Advanced carbon technology:
  Made with 100% coconut shell activated
  carbon and a 0.5 micron nominal
  filtration rating.
• Broad contaminant reduction:
  Designed to address chlorine,
  chloramine, lead, mercury,
  PFOA/PFOS, VOCs, and certain
  emerging contaminants.
• Improved taste and odor:
  Activated carbon filtration helps
  reduce chlorine and other substances
  that affect drinking water’s
  taste and smell.
• Mineral preservation:
  Designed to retain naturally
  occurring dissolved minerals,
  including calcium and magnesium.
• Convenient maintenance:
  Recommended cartridge replacement
  approximately every 8–12 months,
  depending on water quality and usage.

Our upgraded advanced carbon block
uses premium coconut shell activated
carbon to provide complementary
chemical contaminant treatment
and fine particulate filtration.

Chlorine & Chloramine

Activated carbon filtration helps
reduce disinfectant-related
taste and odor while supporting
improved drinking water quality.

Heavy Metals

Manufacturer performance information
includes applications involving
lead, mercury, and certain other
heavy metals.

PFAS & Organic Compounds

The advanced carbon block is
designed for treatment applications
involving PFOA/PFOS, certain
volatile organic compounds,
and select emerging contaminants.

Fine Particulate Filtration

The carbon block’s 0.5 micron
nominal rating provides additional
fine particulate filtration.

A nominal micron rating does
not establish absolute removal
of all particles or microorganisms
of a particular size.

The advanced carbon block used
in this replacement cartridge
has manufacturer performance
documentation describing its
filtration capabilities under
defined testing conditions.

Manufactured in the United States
using 100% coconut shell activated
carbon, the cartridge features
a 0.5 micron nominal
filtration rating.

Manufacturer performance information
addresses chlorine, chloramine,
lead, mercury, PFOA/PFOS,
volatile organic compounds (VOCs),
and other substances.

The carbon block’s materials
are certified to NSF/ANSI
Standard 42 material requirements.
This is distinct from certification
of specific contaminant reduction
claims.

Actual contaminant reduction
and filter service life depend
on incoming water chemistry,
contaminant concentrations,
flow rate, contact time,
and household usage.

Testing of individual filtration
cartridges or media does not
necessarily establish identical
performance in every system
or installation.

documentation below.

Carbon Filtration Performance Data

We generally recommend replacing
your countertop filtration cartridge
approximately every
8–12 months,
depending on incoming water
quality and household usage.

Homes with higher water
consumption or challenging
water conditions may require
more frequent replacement.

Changes in water flow, taste,
or odor may indicate that
a cartridge needs attention,
but these changes are not
reliable indicators of
every contaminant.

Follow the appropriate replacement
and flushing instructions
for your existing countertop
filtration system.

The advanced carbon block
uses filtration technology
designed to reduce unwanted
substances without intentionally
removing naturally occurring
dissolved minerals, including
calcium and magnesium.

This allows customers to
maintain drinking water
filtration without intentionally
stripping water of its
natural mineral content.

This product is intended
for compatible Greenfield
two-stage countertop filtration
systems that are no longer
available for new purchase.

The advanced carbon block
is the currently offered
replacement option.
NanoMetix cartridges are
no longer available.

If you’re unsure which
countertop system you own,
please contact our team
with a photo of your system
or your original order
information.

We’re happy to help confirm
compatibility and guide
you through replacement.
