LSX Salt-Free Whole Home Descaler Replacement Cartridge | 20″ Big Blue

• Salt-free scale prevention:
  Designed to help reduce
  hard water scale formation
  without adding salt
  to the water.
• Retains natural minerals:
  Does not remove calcium
  and magnesium through
  traditional softening.
• Helps protect plumbing:
  May reduce the accumulation
  of mineral scale on
  compatible plumbing
  and water-using equipment.
• No salt replenishment:
  Does not require the
  salt refills associated
  with conventional
  ion exchange softeners.
• No regeneration cycle:
  Operates without routine
  salt-based regeneration.
• No regeneration wastewater:
  Does not require
  a wastewater-producing
  regeneration process.
• Long service life:
  Typical replacement
  interval of approximately
  3 to 5 years,
  depending on conditions.
• Standard housing compatibility:
  Designed for compatible
  4.5″ x 20″ Big Blue
  filter housings.

Hard water contains dissolved
minerals, primarily calcium
and magnesium.

When water is heated
or certain chemical
conditions change,
these minerals can
form deposits on
plumbing surfaces,
fixtures, and
water-using appliances.

LSX uses specialized
scale prevention media
designed to encourage
hardness minerals
to form stable
microscopic crystals
that are less likely
to adhere to surfaces.

This process is
intended to reduce
the formation of
hard mineral scale
while allowing calcium
and magnesium to
remain in the water.

Important:
LSX does not remove
hardness minerals
or reduce measured
water hardness
in the same way
as a conventional
water softener.

Scale prevention
effectiveness depends
on incoming water
chemistry, operating
conditions, and
system design.

Although both technologies
are used to address
hard water concerns,
they work in
different ways.

LSX Salt-Free Descaling

• Designed to reduce scale formation
• Retains dissolved calcium and magnesium
• Does not require salt refills
• Does not require regeneration
• Does not produce regeneration wastewater
• Does not substantially reduce measured hardness

Traditional Salt-Based Water Softening

• Removes calcium and magnesium through ion exchange
• Reduces measured water hardness
• Requires salt or potassium chloride replenishment
• Uses periodic regeneration cycles
• Typically produces regeneration wastewater

Which Is Right for You?
If your primary goal
is to reduce scale
while retaining
naturally occurring
minerals, LSX may
be a suitable option.

If your goal is
to substantially
reduce water hardness
for soap performance
or other hardness-related
concerns, a conventional
water softener may
be more appropriate.

Hard water scale
can accumulate
on surfaces exposed
to mineral-rich water,
particularly in
heated water applications.

LSX media is designed
to help reduce
the formation of
adherent mineral scale.

Potential applications
include:

• Water heaters
• Household plumbing
• Faucets and fixtures
• Showerheads
• Compatible water-using appliances

Actual results
depend on water
hardness, temperature,
flow rate, and
other water chemistry
conditions.

Salt-free scale
prevention does
not necessarily
eliminate all
visible mineral
residue or
existing deposits.

The cartridge is
primarily intended
to help manage
new scale formation
rather than remove
established buildup.

This replacement
cartridge is designed
for compatible
whole home water
treatment systems
using a standard
Big Blue housing.

Please verify
compatibility with
your existing
system before
ordering.

LSX replacement
cartridges are designed
for extended service
with minimal routine
maintenance.

The recommended
replacement interval
is approximately
every 3 to 5 years,
depending on water
chemistry and
operating conditions.

Factors that may
influence service
life include:

• Incoming water hardness
• Water chemistry and pH
• Household water consumption
• Flow rate
• Temperature
• Media capacity and operating conditions

The cartridge does
not require salt
replenishment or
routine regeneration.

When replacing
the cartridge,
follow the appropriate
housing instructions
for shutting off
water, relieving
pressure, and
reassembling
the system.

If your water
contains elevated
sediment or other
conditions that
could interfere
with the media,
additional pretreatment
may be appropriate.

The LSX cartridge
is intended for
hard water scale
prevention.

It is not a
drinking water
contaminant reduction
filter.

It should not
be relied upon
to remove contaminants
such as lead,
arsenic, PFAS,
fluoride, nitrates,
or microorganisms.

LSX also does
not remove calcium
and magnesium
from the water.

For households
with additional
water quality
concerns, an
appropriately
selected filtration
system may be
needed alongside
scale prevention.

Water testing
can help determine
whether additional
treatment is
appropriate.

For additional
information about
the scale prevention
media used in
this cartridge,
review the
manufacturer’s
media brochure.

The brochure
provides background
on the treatment
technology and
its intended
scale prevention
applications.
