Three Housings—Not One Cartridge

EACH MEDIUM GETS A FULL-SIZE HOUSING

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—more media volume, 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 the carbon behind it is never wasted on dirt—great for Duck Key water lines.

2 GAC

Granular Activated Carbon

Model 2045 GAC

The chemical workhorse—made to handle tough stuff, including hard water in the Keys.

3 CTO

Compressed Activated Carbon Block

Model 2045 CTO

A dense final pass that leaves no shortcuts for anything still in the water—especially helpful with Duck Key’s hard water.

Three full-size housings instead of one shared shell—ideal for Keys water.
More contact time between the water and the media—great for Duck Key homes.
Individually replaceable - change only the spent cartridge.
Longer intervals between filter changes for busy Duck Key households.
A far longer chemical reduction list than a single cartridge.
Helps protect your plumbing from the main line onward—great for Duck Key’s hard water.

Inside the Housings

ALL THREE FILTERS, INSIDE THE BLUE HOUSINGS

Three full-size housings on one manifold, each holding a different medium—built for the kind of water many Duck Key homes see. Here’s what sits inside each one, in order.

X-ray view of the first blue housing, showing the depth-wound polypropylene sediment cartridge inside.

MPP Sediment Pre-Filter

Model 2045 PP

Inside: a depth-wound polypropylene cartridge. Water moves from the outer windings to the core, trapping rust, sand, silt and sediment before the carbon—ideal for Keys water.

X-ray view of the second blue housing, showing the loose granular activated carbon bed inside.

GAC Granular Activated Carbon

Model 2045 GAC

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

CTO Carbon Block

Model 2045 CTO

Inside: carbon compressed into a solid wall around a hollow core. There is no loose path through it, so the last of the chlorine, fine particles and residual organics have nowhere to slip past—great for Duck Key homes.

The Chemical Story

BUILT FOR SPECIFIC IMPURITIES & CHEMICAL CONCERNS IN DUCK KEY

Most whole-home filters are sold on taste and scale. With two full housings of activated carbon, this one targets a longer, more technical list—what Florida Keys homeowners 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

Physical & Particulate

Stages 1 & 3

Rust, Dirt, Sand & Silt
Sediment & Suspended Solids
Pipe Scale Fragments (Hard Water)
Microparticles & Fine Particulate (Florida Keys water)

Stage 2 - Loose Granular Carbon (GAC)

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.

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 - which is exactly why it goes last.

The order is the design—for better results in Duck Key

Sediment first, so the expensive carbon is never spent on dirt. Loose granular carbon second, for volume and chemical capacity. Dense carbon block last, for a tight final pass—ideal for Duck Key water and hard-water scale protection.
