PureSync Home Replacement Filter Pack

• Complete four-stage replacement:
  Includes the filtration cartridges needed
  to maintain your PureSync Home
  Whole House Filtration System.
• Comprehensive household filtration:
  Designed to address sediment, chlorine,
  chloramine, certain heavy metals,
  PFAS, VOCs, and other unwanted
  substances in household water.
• Advanced nanofiber filtration:
  Electropositive filtration technology
  helps capture extremely fine particles,
  certain microorganisms, and other
  suspended contaminants.
• Premium carbon block technology:
  Advanced carbon filtration provides
  complementary treatment for a broad
  range of chemical contaminants.
• Improved taste and odor:
  Multiple filtration stages help reduce
  chlorine and other substances that
  contribute to unpleasant water
  taste and smell.
• Mineral preservation:
  Maintains naturally occurring dissolved
  minerals, including calcium and magnesium.
• Whole home water treatment:
  Provides filtration at the point of entry,
  helping improve water quality throughout
  the home’s plumbing system.
• Convenient maintenance:
  Replacement intervals vary by filtration
  stage, household water consumption,
  and incoming water quality.

Stage 1 — Sediment Prefiltration

The first stage captures sediment,
sand, rust, silt, and other suspended
particles commonly found in
household water supplies.

By reducing particulate buildup,
these filters help protect downstream
filtration stages and support
consistent system performance.

Stage 2 — Electropositive Nanofiber Filtration

Advanced electropositive nanofiber
technology is designed to capture
extremely fine particles, including
certain bacteria, viruses, cysts,
and other suspended contaminants.

Its specialized filtration structure
provides fine particulate treatment
while supporting the water flow
required for whole house applications.

Stage 3 — Advanced Carbon Block Filtration

A high-performance carbon block
provides broad chemical contaminant
reduction through advanced adsorption
and fine particulate filtration.

This stage is designed to address
chlorine, chloramine, certain heavy
metals, PFAS, volatile organic
compounds (VOCs), and select
emerging contaminants.

Working alongside the electropositive
nanofiber stage, the carbon block
provides complementary treatment
for a wide range of household
water quality concerns.

Stage 4 — Final Carbon Polishing

The final carbon filtration stage
provides additional treatment to
refine water quality and help reduce
residual substances that may affect
taste and odor.

Together, these four stages provide
comprehensive whole house filtration
while preserving naturally occurring
dissolved minerals.

PureSync Home combines complementary
filtration technologies selected
for their performance, reliability,
and ability to address different
water quality concerns.

Sediment Prefiltration

The sediment stage helps capture
suspended particles that can contribute
to buildup and premature loading
of downstream filters.

Electropositive Nanofiber Filtration

Advanced electropositive filtration
technology is designed to capture
extremely fine particles and certain
microorganisms through specialized
adsorptive filtration mechanisms.

Advanced Carbon Block Filtration

High-performance carbon filtration
provides complementary chemical
contaminant treatment, including
applications involving chlorine,
chloramine, certain heavy metals,
PFAS, VOCs, and other substances.

Final Carbon Polishing

The fourth stage provides additional
carbon filtration to refine water
quality, taste, and odor.

Manufacturer performance data provides
valuable information about filtration
capabilities under defined testing
conditions.

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

Replacement frequency varies by
filtration stage, incoming water
quality, household size, and
overall water consumption.

Stage 1 — Sediment Prefilters

We generally recommend replacing
sediment prefilters approximately
every 3 months,
depending on sediment levels
and household water usage.

Homes with higher sediment
concentrations may require
more frequent replacement.

Stages 2, 3 & 4 — Main Filtration Cartridges

We generally recommend replacing
the primary filtration cartridges
approximately every
6–12 months.

Larger households, higher water
consumption, and challenging incoming
water conditions may require
more frequent replacement.

Signs that your filters may need
attention include reduced water
flow, noticeable changes in taste
or odor, or reaching the recommended
replacement interval.

These recommendations reflect
our experience supporting
Greenfield filtration systems
in real-world household conditions.

Changes in taste, odor, or flow
are not reliable indicators of
every contaminant. Following
recommended replacement intervals
is important even when water
appears unchanged.

PureSync Home is designed to reduce
unwanted substances while retaining
naturally occurring dissolved minerals,
including calcium and magnesium.

Unlike filtration technologies that
remove most dissolved minerals,
the PureSync Home system uses
complementary filtration stages
selected to address specific
water quality concerns without
intentionally stripping water
of its natural mineral content.

This replacement pack is designed
for compatible PureSync Home
four-stage whole house filtration
systems.

It is not intended for PureSync
Home Lite or PureSync undersink
filtration systems.

If you’re unsure which PureSync
system you own or which replacement
filters you need, our team is
happy to help confirm compatibility.

PureSync Home replacement cartridges
are designed for straightforward
maintenance using the appropriate
housing tools and standard
filter replacement procedures.

Before replacing filters, shut off
the incoming water supply and
relieve pressure from the system.

Follow the replacement instructions
for your specific system, including
proper cartridge positioning,
housing reassembly, and flushing
procedures.
