Legacy Whole Home Replacement Filter Pack | Customizable

Next, choose whether
your replacement pack
should include a
mineralizing cartridge.

Yes: Include Mineralizer

Select this option if
your existing system
includes a mineralizing
stage and you are ready
to replace that cartridge.

The mineralizer provides
the dedicated mineral
treatment function
of compatible legacy
filtration systems.

No: Do Not Include Mineralizer

Select this option if
your system does not
use a mineralizer,
or if your existing
mineralizing cartridge
does not currently
require replacement.

Not sure?
Our team can help
identify whether your
system includes a
mineralizing stage.

Finally, choose whether
your replacement pack
should include an
LSX cartridge.

LSX is an additional
treatment component
used in certain
legacy whole home
system configurations.

Your selection should
match your existing
system and water source.

Available Options

• City Water LSX:
  Select if your existing
  system uses the LSX
  configuration intended
  for municipal water.
• Well Water LSX:
  Select if your existing
  system uses the LSX
  configuration intended
  for private well water.
• No LSX:
  Select if your system
  does not use LSX or
  your existing cartridge
  does not yet require
  replacement.

LSX Replacement Interval:
LSX typically requires
replacement approximately
every 3 to 5 years,
depending on water
quality and usage.

This means you may
not need to replace
your LSX cartridge
every time you
replace the other
filtration stages.

If you’re uncertain
which LSX option
your system uses,
contact our team
before ordering.

Different cartridges
perform different
functions within
your whole home
filtration system.

Sediment Filtration

The sediment filter
captures suspended
particles before
they reach the
remaining filtration
components.

This helps protect
downstream cartridges
and reduce particulate
buildup.

Carbon Block Filtration

Activated carbon
helps reduce chlorine,
unpleasant tastes
and odors, and
certain organic
contaminants.

Actual reduction
depends on the
specific carbon
block cartridge
and operating
conditions.

NanoCeram Filtration

NanoCeram uses
specialized electropositive
filtration media
to capture very
fine particles
through adsorption
and mechanical
filtration mechanisms.

Its filtration
characteristics
differ from those
of conventional
activated carbon.

Mineralizing Cartridge

The mineralizer
provides a separate
mineral treatment
stage for compatible
systems equipped
with this component.

LSX Cartridge

LSX is an additional
treatment component
used in certain
legacy configurations.

The appropriate
replacement depends
on the original
system arrangement
and water source.

Regular filter replacement
helps maintain the
performance of your
legacy whole home
filtration system.

Different filtration
components may have
different maintenance
requirements.

Sediment Filters

Sediment filters
typically require
more frequent
replacement because
they capture dirt,
rust, sand, and
other suspended
particles.

Replacement frequency
depends on incoming
water quality and
household water usage.

Carbon Block and NanoCeram Filters

These cartridges
generally require
periodic replacement
based on water
quality, usage,
and cartridge
capacity.

For many applications,
replacement is
typically recommended
approximately every
6 to 12 months,
subject to the
specific cartridge’s
maintenance guidance.

Mineralizing Cartridge

Replacement requirements
depend on the mineral
media composition
and system usage.

LSX Cartridge

LSX typically requires
replacement every
3 to 5 years,
depending on water
quality and usage.

Because filter life
varies between stages,
you may not need
to replace every
component at the
same time.

Sediment filters often
require replacement
more frequently than
other filtration
components.

Keeping additional
sediment cartridges
on hand makes routine
maintenance more
convenient.

Extra sediment filters
are available separately
for compatible systems.

This replacement pack
is intended for
compatible legacy
Greenfield Water
Solutions whole
home filtration
systems.

Earlier systems
may have different
filter configurations,
housing arrangements,
or optional treatment
stages.

Before ordering,
please confirm:

• Your existing primary filtration combination
• Whether your system includes a mineralizer
• Whether your system includes LSX
• Whether your LSX is configured for city or well water

If you are unsure,
our team can review
photos of your system
and help identify
the appropriate
replacement options.

Important:
Selecting a different
filtration cartridge
may change the
contaminant reduction
capabilities of
your system.

Replacement cartridges
should match the
appropriate system
configuration and
installation requirements.

Follow the applicable
replacement instructions
when servicing your
legacy whole home
filtration system.

Before replacing
cartridges, shut off
the incoming water
supply and relieve
system pressure
according to the
installation guide.

Install each replacement
cartridge in its
designated housing.

Inspect housing seals
and O-rings, restore
water pressure carefully,
and check for leaks
before returning
the system to
normal operation.
