PureSync Lite Compact Undersink Water Filtration System

• Three-stage filtration:
  Combines electropositive nanofiber technology,
  advanced carbon block filtration, and
  a final carbon polishing stage.
• Broad contaminant reduction:
  Designed to address chlorine, chloramine,
  lead, mercury, PFOA/PFOS, fluoride, VOCs,
  and certain emerging contaminants.
• Fine particulate filtration:
  Complementary filtration technologies
  help capture ultrafine particles,
  microplastics, and certain cysts.
• Improved taste and odor:
  Two complementary carbon filtration stages
  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 under-sink 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.

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 — 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.

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.

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.

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.
