PureSync Lite Replacement Filter Pack

• Complete three-stage replacement:
  Includes the filtration cartridges needed
  for your PureSync Lite undersink system.
• Broad contaminant reduction:
  Complementary filtration technologies designed
  to address chlorine, chloramine, lead,
  mercury, PFOA/PFOS, VOCs,
  and certain emerging contaminants.
• Fine particulate filtration:
  Advanced filtration media help capture
  ultrafine particles, microplastics,
  and certain cysts.
• Improved taste and odor:
  Two carbon filtration stages help reduce
  chlorine and other substances that affect
  drinking water’s taste and smell.
• Mineral preservation:
  Retains naturally occurring calcium,
  magnesium, and other dissolved minerals.
• Convenient maintenance:
  Recommended replacement every 6–12 months,
  depending on household size, usage,
  and water quality.

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.

Stage 3 — Carbon Block Polishing

A final high-quality activated carbon block
provides additional chlorine reduction
and polishing for improved taste and odor.

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

The PureSync Lite replacement pack combines
complementary filtration technologies selected
for broad contaminant reduction.

The advanced Stage 2 carbon block 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.

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.

performance information for each filtration
stage below.

For optimal performance, we recommend
replacing your PureSync Lite 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 reflect our
experience supporting Greenfield filtration
systems in real-world household conditions.

Replacement instructions are included
with your filter pack to make ongoing
maintenance straightforward.

PureSync Lite is designed to retain
naturally occurring dissolved minerals,
including calcium and magnesium,
throughout the filtration process.

An optional inline mineralizer is
available for customers who prefer
additional mineral enrichment
or a different taste profile.

Because the filtration system already
retains naturally occurring dissolved
minerals, this add-on is entirely optional.

Replacement instructions are included
with your filter pack, and a downloadable
guide is also available below.
