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—so you get more media volume, more contact time, and longer intervals between changes. Each cartridge is replaced individually, so you only change what’s spent—ideal for North Key Largo’s humid, coastal conditions.

1 MPP

Polypropylene Sediment Pre-Filter (Florida Keys Ready)

Model 2045 PP

Takes the physical load first, so the carbon behind it isn’t wasted on grit and sediment.

2 GAC

Granular Activated Carbon

Model 2045 GAC

The chemical workhorse—volume, surface area, and capacity for the hard stuff common in Keys water.

3 CTO

Compressed Activated Carbon Block (Keys Water Upgrade)

Model 2045 CTO

A dense final pass that leaves no shortcuts for anything still in the water—great for coastal North Key Largo.

Inside the Housings

ALL THREE FILTERS, INSIDE THE BLUE HOUSINGS (KEY LARGO AREA)

Three full-size housings on one manifold, each holding a different medium—built for North Key Largo’s coastal environment. Here’s what’s inside each one, in the order your water meets it.

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

MPP Sediment Pre-Filter (Coastal-Grade)

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 it reaches the carbon.

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

GAC Granular Activated Carbon

Model 2045 GAC

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

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

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.

The Chemical Story

BUILT FOR KEY LARGO WATER CONCERNS & CHEMICALS

In the Florida Keys’ warm, humid, coastal conditions, water quality and equipment reliability matter. This whole-home system isn’t just about taste or moderate hardness—two full activated-carbon housings target 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
  • Microparticles & Fine Particulate

Stage 2 - Loose Granular Carbon

Volume and capacity for Key Largo 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.
  • 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.
  • Slower by design—perfect for the final stage of Keys water polishing.

The order is the design (Built for Coastal Living)

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 humid, coastal Monroe County homes.

THREE STAGES, ONE CLEAN RESULT FOR NORTH KEY LARGO

The Mr. Pure Water 3-Stage Whole-House Water Purification System is engineered to deliver cleaner, fresher, better-tasting water throughout your entire North Key Largo home. Instead of packing every medium into one cartridge, each of the three media gets its own full-size housing, plumbed in series—more media volume, more contact time, and longer intervals between changes. That matters in Monroe County’s warm, humid coastal conditions, where water quality and equipment reliability can be challenged by corrosion and storm-season disruptions. Our advanced 3-layer filtration helps reduce sediment, chlorine, chemicals, bad tastes and odors, and a wide range of contaminants, so every drop you use is safer, healthier, and better-tasting for your family every day.

LONG-LASTING FILTRATION

Premium media delivers consistent, reliable filtration—built for the Keys’ coastal conditions year after year.

HELPS REDUCE SCALE & SEDIMENT

Keeps sediment and pipe scale fragments out of fixtures and appliances—helpful with North Key Largo’s moderate hardness.
