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 commonly discussed is Legionella pneumophila, which can colonize plumbing, water heaters, storage tanks and low-flow stretches of pipe. It’s most concerning where water becomes aerosolized—showers, faucets and some appliances—because those misted droplets are how people are exposed. Because Legionella won’t change taste, smell or appearance, testing and preventive measures are important for McKinnon homeowners who want peace of mind.
Even if your municipal supply arrives treated, Legionella can sometimes re-establish itself inside a house when temperatures, stagnation and deposits let it thrive. Warm domestic hot water, intermittent fixture use, scale and sediment buildup, and biofilm on pipe surfaces all increase the chance of persistence. While many homeowners focus on drinking water quality, the greater exposure risk is usually from mist and spray during daily use; taking steps at the point where water enters a McKinnon home is a key part of reducing that risk.
For a single whole-house solution, the most effective option to physically remove Legionella is a true barrier filter rated for microbial reduction, such as a whole-house ultrafiltration system. Ultrafiltration removes bacteria-sized particles by passing water through a fine membrane rather than relying on adsorption, making it well suited to reduce organisms like Legionella pneumophila before water reaches showers and other fixtures. Installed at the main service line, this approach treats water used throughout your McKinnon residence, not just at one sink.
A correctly sized whole-house ultrafiltration unit is usually used with prefiltration to trap larger sediment so the membrane can run efficiently and have a longer service life. Regular maintenance is essential—barrier filters require periodic servicing to prevent fouling and maintain flow rates. Because controlling Legionella also involves plumbing conditions inside the home, McKinnon homeowners should pay attention to water heater settings, eliminate dead-end lines where possible, and use fixtures regularly. Mr. Pure Water can help evaluate your home and recommend a whole-house configuration that supports a comprehensive Legionella reduction plan.
