Including filter system and high-performance Legionella filter.
Legionella is a naturally occurring bacterium that can grow in building water systems when conditions allow. The species most often referenced is Legionella pneumophila, which can colonize plumbing, water heaters, storage tanks, and sections of pipe with little flow. It’s a particular concern when water is turned into mist—like from showers, faucets, or some appliances—because that’s how people can breathe it in. Because Legionella usually doesn’t change taste, smell, or appearance, testing and preventive steps are important for homeowners in New Harmony.
Even if your municipal supply is treated, Legionella can sometimes regrow inside a house where warmth and stagnation favor it. Conditions such as warm water temperatures, intermittent use of taps, scale and sediment, and biofilm on pipe walls all make it easier for bacteria to persist. While many homeowners focus on drinking-water safety, exposures in New Harmony are often linked to aerosolized water from everyday fixtures; controlling water at the point it enters the home is a useful part of a broader prevention strategy.
For a single, whole-house solution that physically removes Legionella, a true barrier filter rated for microbial reduction is the most effective option—typically a whole-house ultrafiltration unit. Ultrafiltration uses a fine membrane to strain out bacteria-sized particles instead of relying on adsorption for taste and odor, making it well suited to reduce organisms like Legionella pneumophila before water reaches showers and other fixtures. When installed at the main water line, it treats water for the entire New Harmony home rather than just a single tap.
A whole-house ultrafiltration system works best with proper prefiltration to remove larger sediment so the membrane can function reliably and have a longer service life. Regular maintenance is essential—barrier filters need periodic servicing to prevent fouling and preserve flow rates. Because controlling Legionella also involves managing conditions inside the house, New Harmony homeowners should watch heater settings, eliminate dead-end lines, and use fixtures regularly. Mr. Pure Water can help you size and select a whole-house ultrafiltration setup that fits your home and supports a comprehensive approach to reducing Legionella risk.
