Iron is a naturally
occurring element
commonly found
in groundwater,
particularly
private well water.

When dissolved
iron is present,
water may initially
appear clear
as it leaves
the faucet.

After exposure
to oxygen,
the dissolved
iron can oxidize
and form
rust-colored particles.

This process
can contribute
to orange or
brown staining
on household
surfaces.

Common Signs of Iron in Water:

• Orange or brown stains around plumbing fixtures
• Rust-colored residue in sinks and tubs
• Metallic taste in drinking water
• Discoloration after water is exposed to air
• Iron deposits in plumbing and appliances

Iron itself
is not necessarily
a health concern
at the concentrations
typically associated
with staining,
but it can create
significant aesthetic
and maintenance issues.

This specialized
iron reduction
cartridge is
designed to
reduce dissolved
iron in water.

Unlike a standard
sediment filter,
which primarily
captures suspended
particles, an
iron reduction
cartridge is
intended to address
iron that is
present in
dissolved form.

The cartridge
uses specialized
treatment media
to reduce dissolved
iron as water
passes through
the filter.

Its effectiveness
depends on the
incoming iron
concentration,
water chemistry,
flow rate, and
cartridge capacity.

Important:
This cartridge
is not intended
to treat every
form of iron
or all iron-related
water quality
problems.

Water containing
significant amounts
of oxidized iron,
iron bacteria,
or other interfering
contaminants may
require additional
or alternative
treatment.

Dissolved iron
can contribute
to staining
throughout the home,
particularly when
it oxidizes
after exposure
to air.

Reducing iron
before water
enters household
plumbing may
help minimize
new iron-related
deposits.

Potential Benefits Include:

• Less orange and brown staining on fixtures
• Reduced iron residue in sinks and tubs
• Less iron-related buildup in plumbing
• Improved aesthetic water quality
• Reduced iron-related maintenance concerns

Actual results
depend on the
iron concentration,
water chemistry,
and treatment
conditions.

Existing stains
and established
deposits may
require separate
cleaning or
maintenance.

This cartridge
is designed
to reduce new
iron-related
problems rather
than remove
existing deposits.

This cartridge
is designed
for installation
inside a compatible
4.5″ x 20″
Big Blue housing.

The filter is
typically installed
on the main
cold water
supply line,
after the
pressure tank
for well water
applications
or after the
water meter
for municipal
water applications.

The exact
installation location
should account
for the home’s
plumbing configuration,
water chemistry,
and other
treatment equipment.

General Installation Considerations:

• Use a compatible 20″ Big Blue housing
• Follow the housing installation instructions
• Observe applicable flow and pressure requirements
• Install in the appropriate treatment sequence
• Check for leaks after installation

For systems
with multiple
treatment stages,
the correct
installation order
depends on
the incoming
water conditions
and equipment.

Iron treatment
should be selected
based on the
type and concentration
of iron present
in the water.

A water test
can help determine
whether this
cartridge is
appropriate
for your home.

Useful Water Test Parameters:

• Total iron concentration
• Dissolved iron concentration
• Water pH
• Manganese
• Hardness
• Other relevant water chemistry factors

Iron may occur
in dissolved,
oxidized,
or biologically
associated forms.

Different forms
of iron may
require different
treatment methods.

Important:
If your water
contains more
than 3 ppm
of dissolved
iron, or has
significant
additional water
quality concerns,
a different
treatment approach
may be necessary.

Our team can
help review
your water
test results
and determine
whether this
cartridge is
a suitable option.

Like other
water treatment
cartridges,
the iron reduction
filter has
a finite
treatment capacity.

Replacement frequency
depends on:

• Incoming dissolved iron concentration
• Household water consumption
• Water chemistry
• Flow rate
• Cartridge treatment capacity

For best results,
follow the recommended
service conditions
and replacement guidance
for the cartridge.

A noticeable
return of
iron-related
staining or
metallic taste
may indicate
that treatment
performance
has declined.

Periodic water
testing can
provide a more
reliable indication
of iron reduction
performance than
taste or appearance
alone.

This cartridge
does not require
a conventional
salt-based
regeneration cycle.

This cartridge
is specifically
intended for
dissolved iron
reduction.

It is not
a comprehensive
drinking water
purification system.

It should not
be relied upon
to remove
microorganisms,
PFAS, arsenic,
nitrates, or
other unrelated
contaminants
without verified
performance data.

The cartridge
does not replace
the need for
appropriate
disinfection
or other
specialized
treatment
when required.

For private
well water,
periodic testing
is recommended
to monitor
water quality.

this iron reduction
cartridge is
appropriate
for your water?

Our team can
help review
your iron
concentration,
water source,
and existing
filtration setup.

If you already
have a Big Blue
housing installed,
we can also
help confirm
cartridge compatibility.
