PureSync Lite Compact Undersink Water Filtration System

• Three-stage filtration:
  Combines electropositive nanofiber technology,
  advanced carbon block filtration, and
  specialized contaminant reduction media.
• Broad contaminant reduction:
  Designed to address chlorine, chloramine,
  lead, mercury, PFOA/PFOS, VOCs,
  and certain emerging contaminants.
• Two filtration configurations:
  Choose advanced filtration with or without
  dedicated fluoride reduction.
• Fine particulate filtration:
  Complementary filtration technologies help
  capture ultrafine particles, microplastics,
  and certain cysts.
• Improved taste and odor:
  Advanced carbon filtration helps reduce
  chlorine and other substances that affect
  drinking water’s taste and smell.
• Flexible installation:
  Connects to your existing cold-water line
  or the included stainless-steel spigot.
• Compact design:
  Ideal for smaller undersink spaces.
• Mineral preservation:
  Maintains naturally occurring dissolved minerals.
• Efficient operation:
  No electricity or wastewater discharge.
• Convenient maintenance:
  Recommended filter replacement every
  6–12 months, depending on household
  size, usage, and water quality.

Both PureSync Lite configurations provide
comprehensive drinking water filtration.
The difference is the specialized filtration
media used in Stage 3.

With Fluoride Reduction

This configuration incorporates advanced
filtration media designed to reduce fluoride
alongside other unwanted contaminants.
It provides an additional layer of
contaminant reduction for households
seeking broader water quality protection.

Fluoride can be present in both municipal
and private well water. Some municipalities
add fluoride to drinking water, while
fluoride can also occur naturally
in groundwater.

Without Fluoride Reduction

This configuration uses complementary
filtration media to provide broad
contaminant reduction without a
dedicated fluoride-reduction cartridge.

It is a strong option for households
where fluoride reduction is not
a priority.

How to Decide

If you have municipal water, your local
water utility’s water quality report
can help you understand fluoride levels.

For private wells, laboratory testing
is the most reliable way to determine
fluoride concentration.

Our team is also happy to help you
select the configuration that best
matches your water quality concerns.

Stage 1 — Electropositive Nanofiber Filtration

Advanced electropositive filtration technology
designed to capture bacteria, viruses, cysts,
and ultrafine particles while maintaining
strong water flow.

Stage 2 — Advanced Carbon Block Filtration

A premium American-made carbon block
manufactured with 100% coconut shell
activated carbon. Its 0.5-micron nominal
filtration rating provides fine particulate
filtration alongside broad chemical
contaminant reduction.

This stage is designed to reduce chlorine,
chloramine, lead, mercury, volatile organic
compounds (VOCs), PFOA/PFOS, and certain
emerging contaminants, including pharmaceuticals.

It also provides mechanical reduction of
microplastics and certain cysts, including
Cryptosporidium and Giardia.

The combination of high-performance
activated carbon and fine particulate
filtration complements the electropositive
nanofiber stage, contributing to the
system’s broad contaminant-reduction capabilities.

Stage 3 — Advanced Contaminant Reduction

This stage provides additional contaminant
reduction through specialized filtration
media selected for your system configuration.

The fluoride reduction option incorporates
advanced media designed to address fluoride
alongside other unwanted contaminants,
providing an additional layer of filtration
for households seeking broader water
quality protection.

The configuration without dedicated fluoride
reduction also provides complementary
contaminant filtration as part of the
three-stage system.

Together, the three stages provide
comprehensive drinking water filtration
while retaining naturally occurring
dissolved minerals.

PureSync Lite combines multiple filtration
technologies selected for complementary
contaminant reduction.

The advanced carbon block used in Stage 2
has performance data validated through
internal testing and independent
third-party laboratories.

Its materials are certified by NSF International
to NSF/ANSI Standard 42 material requirements.
Contaminant-reduction performance is
documented separately from this certification.

Stage 3 provides additional contaminant
reduction using filtration media selected
for the chosen configuration.
The fluoride reduction option includes
specialized media designed to address
fluoride and other unwanted substances.

Manufacturer testing provides valuable
information about filtration capabilities
under defined conditions. Actual performance
and service life can vary depending on
incoming water quality, contaminant
concentrations, flow rate, household
usage, and other operating conditions.

  are retained

For optimal performance, we recommend
replacing filters approximately every
6–12 months.

Replacement frequency depends on household
size, water consumption, incoming water
quality, and overall system usage.

Larger households or homes with higher
water consumption will often benefit
from replacement closer to every
6–8 months,
while smaller households with lighter
usage may be able to go longer.

These recommendations are based on
our experience supporting Greenfield
filtration systems in real-world
household conditions.

Replacement filter packs are available
for ongoing system maintenance.
Please select the replacement configuration
that matches your system’s fluoride
filtration option.

PureSync Lite can be connected directly
to your existing cold-water line or installed
with the included stainless-steel
drinking water spigot.
