Including filter system and high-performance Legionella filter.
Legionella is a naturally occurring bacterium that can colonize building water systems when conditions allow it to grow. The form most often referenced is Legionella pneumophila, which can establish itself in plumbing, water heaters, storage tanks and low‑flow stretches of pipe. The bacteria become more worrisome when water is turned into mist or spray — for example in showers, faucets and some household appliances. Because Legionella usually doesn’t change a water’s taste, smell, or appearance, homeowners in Runyon who rely on either municipal supply or private wells should consider testing and prevention to reduce exposure.
Even if your incoming supply has been treated, Legionella can sometimes re‑grow inside a home’s plumbing under the right conditions. Warm temperatures typical of Runyon’s humid subtropical climate, intermittent use, scale and sediment buildup, and biofilm on pipe walls can all encourage persistence. While many people focus on drinking water, the primary exposure route is through aerosolized droplets during everyday use. Controlling water quality where it enters your house is a key part of managing that risk.
If you want a single whole‑house filtration solution, a true barrier filter rated for microbial reduction — such as a whole‑house ultrafiltration system — is the most effective at physically removing Legionella. Ultrafiltration uses a fine membrane to strain out bacteria‑sized particles rather than relying on adsorption of tastes and odors, making it well suited to reduce organisms like Legionella pneumophila before water reaches showers and other fixtures. Installed at the main service line in Runyon homes, it treats water used throughout the house rather than just at one faucet.
A correctly sized whole‑house ultrafiltration unit is best paired with a prefilter to catch sand and larger sediment so the membrane can run reliably and last longer. Regular maintenance is important — barrier membranes need periodic service to avoid fouling and to preserve flow rates. Because controlling Legionella also depends on in‑home conditions, Runyon homeowners should monitor water heater settings, address dead‑end piping, and use fixtures regularly. Mr. Pure Water can assess whether a whole‑house ultrafiltration setup fits your property and help design a plan for ongoing Legionella reduction.
