Four Steps, In Sequence

EACH STAGE PROTECTS AND ENABLES THE NEXT—ESSENTIAL IN THE KEYS

In Key Largo and across the Florida Keys, water can carry dirt, sand, sediment and impurities that affect your health, your appliances and the taste of every tap. Four treatment steps deal with it in order—and the order is not arbitrary. Sediment removal keeps the carbon from being wasted on dirt. Carbon strips chlorine and chemicals a UV lamp cannot touch. And by the time water reaches the UV chamber it is clear, which matters more than it sounds: suspended particles cast shadows that let microorganisms slip through un-irradiated.

1 MPP

Polypropylene Sediment Pre-Filter

Captures rust particles, traps dirt, sand, silt, and sediment—helping reduce turbidity common in storage-tank setups in the Keys.

Enables: protects downstream media from clogging.
2 GAC

Granular Activated Carbon (GAC)

Reduces chlorine, improves taste and odor, and helps reduce VOCs, organic chemicals, pesticides, and herbicides—helpful in the Florida Keys.

Enables: removes what UV cannot act on.
3 CTO

Activated Carbon Block

Final polishing stage—further reduces chlorine and VOCs, captures fine particulate, and improves taste and clarity for Key Largo homes.

Enables: clear water, so UV light reaches everything.
4 UV-C

Ultraviolet Sterilization

A stainless chamber where high-intensity UV-C light helps neutralize or inactivate harmful microorganisms—right at your point of entry.

Delivers: pure, healthy water from every tap.

Inside the Housings

ALL THREE FILTERS, PLUS THE UV CHAMBER

Three full-size housings on one manifold—each with a different medium—then a stainless UV chamber. Here’s what’s inside each one, in the order your Key Largo water meets it.

X-ray view of the first blue housing, showing the depth-wound polypropylene sediment cartridge inside—ideal for Key Largo homes using storage tanks and treatment systems.

MPP Sediment Pre-Filter

Model 2045 PP

Inside: a depth-wound polypropylene cartridge. Water works from the outer windings toward the core, so rust, sand, silt, and sediment are held back—helpful with Keys storage tanks.

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. Water threads through slowly, giving chlorine, VOCs, and solvents time to adsorb—great for Florida Keys homes.

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

CTO Carbon Block

Model 2045 CTO

Inside: carbon compressed into a solid wall around a hollow core—ideal for Florida Keys homes so chlorine, fine particles, and residual organics can’t slip past.

X-ray view of the stainless UV chamber, showing the UV-C lamp in its quartz sleeve running the full length of the chamber.

UV-C Sterilization Chamber

Stainless Steel · UV-C Lamp

Inside: a UV-C lamp in a quartz sleeve running the full length of the chamber. Filtered water passes along it and the light disrupts the DNA and RNA of microorganisms—no chemicals added.

Untreated water in MPP GAC CTO UV-C Sterilized water to every tap in Key Largo

Step Four

THE UV SYSTEM HELPS NEUTRALIZE OR INACTIVATE

High-intensity UV-C light disrupts the DNA and RNA of microorganisms so they cannot reproduce—without adding a single chemical to your Florida Keys water.

Cutaway of the stainless steel UV chamber: filtered water enters one end, passes the full length of the UV-C lamp, and exits sterilized at the other end.

Why UV Matters in the Florida Keys

In the Florida Keys, water can travel long distances through dark, damp lines before it reaches your home—and our hot, humid climate can encourage biofilm growth inside plumbing. That’s why biofilm-forming particles are included in this system’s reduction targets. UV-C sterilization at the point of entry adds a powerful final layer of protection to help inactivate harmful microbes throughout your home’s water supply. It’s also a smart match for many Key Largo homes that rely on storage tanks or treatment systems due to the Keys’ limited freshwater supply.

  1. 1

    Water enters the UV chamber.

  2. 2

    High-intensity UV-C light penetrates microorganisms.

  3. 3

    DNA / RNA disruption helps neutralize or inactivate them.

  4. 4

    Cleaner, safer water flows throughout your Key Largo home.

Another Top-Tier Option for the Keys

A membrane physically blocks

  • Our 5-stage RO/UF system stops organisms at a 0.01-micron barrier—great for Keys water setups.
  • Removes contaminants from the water rather than neutralizing them.
  • Also cuts turbidity and microplastics as a side effect of the barrier.
  • A bigger investment, at the top of the range.

This System

UV-C inactivates with light

  • Lets organisms pass, then disrupts their DNA so they cannot reproduce.
  • Adds nothing to the water—no chemicals, no aftertaste.
  • Works regardless of particle size, as long as the water is clear.

PREMIUM FILTRATION + ULTRAVIOLET PROTECTION FOR KEY LARGO HOMES

The Mr. Pure Water 3-Stage Whole-House Water Purification System with UV Sterilization combines premium sediment and carbon filtration with high-intensity ultraviolet protection to deliver cleaner, fresher, better-tasting water throughout your entire home in Key Largo and the Florida Keys. Water hits the MPP sediment pre-filter, then granular activated carbon, then a compressed carbon block, and finally passes through a stainless chamber where a UV-C lamp irradiates it before it goes out to the house. Each step protects and enables the next: sediment removal helps keep the carbon from being wasted on grit, carbon reduces chlorine and other chemicals a lamp can’t touch, and clear water lets the UV reach every organism rather than leaving shadows for them to hide in—especially important in our hot, humid coastal climate. And because salt air can accelerate corrosion on plumbing and fixtures around Monroe County, cleaner water can also be a smart part of protecting what’s connected to your system.

HIGH-FLOW PERFORMANCE

Engineered for maximum flow so your Key Largo home never skips a beat.

LONGER-LASTING FILTRATION

Premium media delivers consistent, reliable filtration year after year in Monroe County.

SPOT-FREE DISHES
