Three housings—not one cartridge

EACH STAGE 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. In Key Colony Beach’s coastal salt air, that extra protection helps from the main line on. Each cartridge is replaced individually, so you only change what is spent.

1 MPP

Polypropylene sediment pre-filter (Stage 1)

Model 2045 PP

Takes the physical load first, so the carbon behind it is never wasted on dirt—great for island living in Key Colony Beach.

2 GAC

Granular Activated Carbon

Model 2045 GAC

The chemical workhorse—built for the hard stuff, from chlorine to everyday odors in the Keys.

3 CTO

Compressed Activated Carbon Block

Model 2045 CTO

A dense final pass—so there are no shortcuts for anything still in your Key Colony Beach water.

Three full-size housings instead of one shared shell.
More contact time between the water and the media.
Individually replaceable—change only the spent cartridge.
Longer intervals between filter changes.
A far longer chemical reduction list than a single cartridge.
Helps protect your plumbing from the main line onward—important in coastal salt air.

Inside the housings

ALL THREE FILTERS, INSIDE THE BLUE HOUSINGS

Three full-size housings on one manifold, each holding a different medium—built for Key Colony Beach water from the first stage to the last.

MPP sediment pre-filter (Stage 1)

Model 2045 PP

Inside: a depth-wound polypropylene cartridge. Water moves from the outer windings toward the core, trapping rust, sand, silt, and sediment before it reaches the carbon.

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.

CTO Carbon Block (Final Polish)

Model 2045 CTO

Inside: carbon compressed into a solid wall around a hollow core. No loose path through it—so chlorine, fine particles, and residual organics can’t slip past in your Key Colony Beach home.

The Chemical Story

BUILT FOR SPECIFIC IMPURITIES & CHEMICAL CONCERNS IN THE KEYS

Most whole-home filters are sold on taste and scale. With Key Colony Beach’s moderate hardness and coastal conditions, we focus on what matters: two full housings of activated carbon that go after 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

Physical & Particulate

Stages 1 & 3

Rust, Dirt, Sand & Silt
Sediment & suspended solids
Pipe scale fragments (moderate hardness)
Microparticles & fine particulate

Stage 2 - Loose Granular Carbon

Volume & capacity for Keys homes

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. Great for Monroe County water.
But water can channel through gaps between the granules.

Stage 3 - Compressed Carbon Block

No shortcuts

Carbon compressed into a solid block—no gaps for water to channel through.
The tight structure also catches fine particulate matter.
Everything that survived stage 2 gets a second, denser pass.
Slower by design—perfect for the final stage of Keys-wide clean water.

The order is the design—for Keys water

Sediment first, so the expensive carbon isn’t spent on dirt. Loose granular carbon second, for volume and chemical capacity. Dense carbon block last, for a tight final pass—ideal for Key Colony Beach homes in the Florida Keys.
