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

Greenfield Countertop Replacement Filter

provides continued filtration support for our

discontinued two-stage countertop water

filtration system.

Although the original countertop system

is no longer available for purchase,

we continue to offer compatible replacement

filters so existing customers can maintain

their systems and enjoy clean, great-tasting

drinking water.

Featuring our upgraded premium American made

advanced carbon block filter,

this replacement cartridge uses

100% coconut shell activated carbon

and a 0.5 micron nominal filtration rating

to provide broad contaminant reduction

and improved drinking water quality.

Designed to address chlorine, chloramine,

certain heavy metals, PFAS, volatile organic

compounds (VOCs), and other unwanted

substances while preserving naturally

occurring dissolved minerals.

In Stock & Ready to Ship!

Replacement filters are currently in stock

and typically ship within 5–7 business days.

Advanced Carbon Block Filtration

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.

Filter Performance & Testing

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.

Replacement Timing & Maintenance

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…
