Including filter system and high-performance Giardia filter.
Giardia is a tiny parasite that can enter water supplies as hardy cysts; you might also see it called Giardia intestinalis or Giardia lamblia. Because these organisms are microscopic they won’t change the taste, smell, or look of your water, making them easy to miss. Many Key West homeowners choose to add protection where water enters the house so that the whole plumbing system gets an extra barrier against unseen contaminants.
Water can pick up contaminants from damaged pipes, cross-connections, or runoff after storms — realities that matter in coastal areas like Key West where hurricane season and storm surge can affect water and storage. Even when municipal treatment is in place, some households prefer an added layer of safety, especially if family members are sensitive to water quality. A whole-house filter treats every shower, faucet, and appliance the same, giving Monroe County homeowners consistent protection throughout their plumbing.
The single most effective whole-house option for addressing Giardia is an absolute, cyst-rated membrane filter. These systems remove Giardia cysts with a physical, fine-pore barrier instead of relying on chemicals. When the membrane is sized to your home’s flow requirements it can protect multiple fixtures simultaneously without leaving gaps in coverage — a practical mechanical solution for Key West houses concerned about cysts.
Installed on the main service line, a whole-house membrane filter ensures all incoming water to a Key West home passes through the barrier. Proper micron rating and routine maintenance are essential to keep flow and protection steady; many installations also use a prefilter to capture larger sediment and reduce membrane wear. For residents in Old Town, New Town, or other neighborhoods across the Keys, Mr. Pure Water can size and match a system to your plumbing and household demand.
