Installed at Your Marathon Home

THIS IS WHAT IT LOOKS LIKE ON YOUR MARATHON WALL

Three blue housings on a wall-mounted manifold, plumbed into the main line as water enters your Marathon home—compact and tidy, not a tank taking over the garage.

The 3-stage whole-house purification system installed on an exterior wall in Marathon: three blue filter housings on a wall-mounted manifold, plumbed into the incoming main line.
The 3-stage system installed at a Marathon customer’s home.

Three Housings, Not One Cartridge (Florida Keys Ready)

EACH STAGE GETS A FULL-SIZE HOUSING—BUILT FOR KEYS CONDITIONS

Single-cartridge systems pack every medium into one shell. This one gives each of the three media its own housing, plumbed in series on a wall-mounted manifold—great for Marathon homes on municipal water, wells, or cisterns where sediment control matters. More media volume means more contact time, and longer intervals between changes. Each cartridge is replaced individually, so you only change what’s spent.

1 MPP

Polypropylene Sediment Pre-Filter

Model 2045 PP

Takes the physical load first, so carbon media isn’t wasted on sand and grit common in Keys systems.

2 GAC

Granular Activated Carbon

Model 2045 GAC

The chemical workhorse—built with the volume, surface area, and capacity to handle tough Marathon water conditions.

3 CTO

Compressed Activated Carbon Block (Florida Keys)

Model 2045 CTO

A dense final pass that leaves no shortcuts for anything still in your water.

  2. 2

    Stage 2 - GAC

    Granular activated carbon reduces chlorine, bad tastes, odors, VOCs, chemicals, and disinfection byproducts—ideal for Marathon’s municipal or cistern water.

  3. 3

    Stage 3 - CTO

    The carbon block gives a final polish, so great-tasting water reaches every tap in your Marathon home.

Inside the Housings (Built for the Keys)

ALL THREE FILTERS, INSIDE THE BLUE HOUSINGS (Marathon, FL)

Three full-size housings on one manifold, each holding a different medium—ideal for Marathon’s mix of municipal and well/cistern water. Here’s what’s inside, in order.

X-ray view of the first blue housing, showing the depth-wound polypropylene sediment cartridge that helps handle Marathon sediment.

MPP Sediment Pre-Filter for Marathon Homes

Model 2045 PP

Inside: a depth-wound polypropylene cartridge. Water flows from the outer windings toward the core, trapping rust, sand, silt & sediment before it reaches the carbon—great for Keys wells/cisterns.

X-ray view of the second blue housing, showing a bed of loose granular activated carbon inside for better taste and odor control.

GAC Granular Activated Carbon

Model 2045 GAC

Inside: a full housing of loose carbon granules. The gaps are the point—water threads through slowly, giving chlorine, VOCs and solvents time to adsorb for cleaner Marathon water.

X-ray view of the third blue housing, showing the compressed carbon block and its hollow centre channel for Florida Keys water.

CTO Carbon Block

Model 2045 CTO

Inside: carbon compressed into a solid wall around a hollow core—so the last of the chlorine, fine particles, and residual organics have nowhere to slip past.

The Chemical Story

BUILT FOR MARATHON WATER IMPURITIES & CHEMICAL CONCERNS

In the Florida Keys, water isn’t just about taste and scale. With municipal supply or well/cistern setups, sediment control and real filtration matter—this 3-stage system targets the contaminants people actually test for.

Chlorine & Byproducts

Stages 2 & 3
  • Chlorine
  • THMs / Trihalomethanes
  • Disinfection Byproducts
  • Chlorine Taste & Odor

Agricultural Chemicals

Stage 2 - GAC
  • Pesticides
  • Herbicides
  • Lawn-Care Runoff
  • Organic Chemicals

Industrial & Volatile

Stages 2 & 3
  • Industrial Solvents
  • VOCs
  • Residual Organics
  • Other Dissolved Contaminants (Marathon water)

Physical & Particulate

Stages 1 & 3
  • Rust, Dirt, Sand & Silt
  • Sediment & Suspended Solids (Wells/Cisterns)
  • Pipe Scale Fragments
  • Microparticles & Fine Particulate (Well/Cistern Friendly)

Stage 2 - Loose Granular Carbon

Volume and capacity

  • Loose granules pack enormous surface area into the housing.
  • Water moves through quickly, so flow stays high.
  • High chemical capacity before the media is spent.
  • But water can channel through gaps between the granules—especially with sediment.

Stage 3 - Compressed Carbon Block

No shortcuts

  • Carbon compressed into a solid block with no gaps to channel through.
  • The tight structure also catches fine particulate matter.
  • Everything that survived stage 2 gets a second, denser pass—great for Keys water.
  • Slower by design—ideal as the final stage for Florida Keys water.

The order is the design (Made for Marathon)

Sediment first, so the expensive carbon isn’t spent on dirt—especially helpful for Marathon well/cistern setups. Loose granular carbon second, for volume and chemical capacity. Dense carbon block last, for a tight final pass.
