The System Itself

ONE HOUSING, ONE UV CHAMBER, MOUNTED AT YOUR MAIN LINE IN KEY WEST

The whole system is a single filter housing and a stainless UV chamber, plumbed in where water enters your home. Compact for an outdoor run—perfect for Key West’s salt air and tight spaces.

Single-stage purification system with UV sterilization installed on an exterior wall: one filter housing and a stainless UV chamber on the incoming main line.
The system installed at a customer’s Key West home.

The UV Advantage

FILTRATION AND UV DO TWO DIFFERENT JOBS IN KEY WEST

Media filters are excellent at particles and dissolved chemicals, but they do not reliably deal with living things. UV-C removes nothing from the water—it disrupts the DNA and RNA of microorganisms so they can’t reproduce. Running filtration first also makes the UV work better, because clear water lets the light reach everything—helpful in Key West after storms or surge-related water changes.

High-Performance UV-C Chamber

A dedicated sterilization stage plumbed in after the filter—ideal for Key West.

Chemical-Free Solution

Nothing is added to your water—no chlorine, no aftertaste.

Premium 304 Stainless Build

A corrosion-resistant chamber built for Key West salt air on your main line.

Easy Maintenance

A long-life lamp with a simple, scheduled replacement.

Cutaway of the stainless UV chamber: water enters, passes the UV-C lamp, and exits sterilized—ideal for coastal Key West homes.

Why UV Matters in Key West

In the Florida Keys, water can travel miles through dark, damp lines before it reaches your home. Warm, humid conditions can support microorganisms and biofilm growth—so whatever treatment happened at the plant isn’t the whole story. 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, especially after storm surge or hurricane season events that can affect water quality and storage.

Incoming Water Purified Water
  1. 1

    Water enters the UV chamber.

  2. 2

    High-intensity UV-C light penetrates microorganisms.

  3. 3

    UV disrupts DNA/RNA to help neutralize or inactivate microbes.

  4. 4

    Cleaner, safer water flows throughout your Key West home.

Common Harmful Microorganisms UV-C Helps Inactivate

Bacteria

  • Coliform Bacteria
  • Salmonella
  • Shigella
  • Legionella
  • Campylobacter
  • Vibrio cholerae
  • Pseudomonas
  • Staphylococcus
  • Enterococcus

Viruses

  • Norovirus
  • Rotavirus
  • Hepatitis A Virus
  • Enteric Viruses
  • Adenoviruses

Protozoa & Parasites

  • Giardia
  • Cryptosporidium
  • Cysts
  • Protozoa

Other Microorganisms

  • Algae
  • Mold Spores
  • Mildew-Related Microbes
  • Biofilm-Forming Microorganisms
  • Fungi
  • Microbial Contaminants

UV-C helps inactivate microorganisms by disrupting DNA/RNA. Effectiveness varies with water quality, flow rate, and system design.

An Ideal Final Barrier

Great for Key West homeowners who want extra defense against bacteria, viruses, protozoa, algae, mold spores, and other microorganisms.

3-Layer Media Filtration

Removes what’s in your Key West water

  • Physically traps sand, silt, rust flakes, and debris.
  • Adsorbs chlorine, VOCs, PFAS and industrial chemicals.
  • Improves clarity, taste and odor.
  • Does not reliably deal with living organisms.

UV-C Sterilization

Handles what’s alive in your water

  • Disrupts DNA and RNA so microbes can’t reproduce.
  • Adds nothing to the water—no chemicals, no aftertaste.
  • Targets biofilm-forming microbes that can build up in warm, humid Florida Keys plumbing.
  • Works best after filtration, when the water runs clear.

Standard vs. UV-Equipped for Key West homes

WHAT THE UV UPGRADE ACTUALLY ADDS FOR THE KEYS

Both systems treat the whole house at the main line, and both are installed, tested, and backed the same way. What changes is the cartridge inside the housing—and whether anything addresses what’s alive in your water, which can matter in warm, humid Key West.

The upgrade is $500—extra protection a filter alone can’t provide, especially during hurricane season.

A media filter is excellent at particles and dissolved chemicals, but it does not reliably deal with living organisms. UV-C does not remove anything from your water—it disrupts the DNA and RNA of bacteria, viruses, and protozoa so they cannot reproduce, using no chemicals at all. In the Florida Keys, hurricane season and storm surge can affect water quality and storage—UV helps cover that last layer. On moderate-hardness water, ask us which build is the better fit—the standard system carries a polyphosphate scale-control layer that the UV build does not.

PREMIUM WHOLE-HOME FILTRATION + UV PROTECTION FOR KEY WEST

The Mr. Pure Water Whole House Water Purification System with UV Sterilization combines advanced 3-layer filtration with powerful UV-C technology to deliver cleaner, better-tasting, and microbiologically safer water throughout your entire Key West home.

The middle gradient media handles the broad chemical and clarity range—chlorine, VOCs, dissolved solids, microplastics. The inner activated carbon core does the final polish and takes on PFAS and industrial chemicals. Then a 304 stainless chamber with a UV-C lamp finishes the job on what filtration alone cannot reach, giving your family the ultimate in water quality, protection, and peace of mind—especially during hurricane season and after storms.
