Point-of-Use Filtration
The first line of defense after a positive Legionella test — POU filters installed at every at-risk fixture to protect patients, residents, and building occupants while remediation is underway.
Immediate Protection at the Point of Use
When a water system tests positive for Legionella, the priority is immediate protection of building occupants — particularly in healthcare settings where immunocompromised patients face the highest risk. Point-of-use (POU) filtration provides that protection by installing certified 0.2-micron filters directly at each fixture, physically removing Legionella and other waterborne pathogens before water reaches the user.
POU filters are the most widely recommended immediate-response measure following a positive Legionella detection. They are effective regardless of the underlying cause of contamination, require no changes to the distribution system, and can be deployed rapidly across an entire facility. For healthcare facilities, maintaining a stock of POU filters on-site is a best practice that enables same-day response when a positive result is received — eliminating the delay of emergency procurement.
RW Water Services supplies, installs, and manages POU filtration programs for healthcare facilities, long-term care facilities, hotels, and other high-risk buildings. We handle everything from initial deployment and fixture mapping to filter change-out schedules and documentation — so your team can focus on patient care while we manage the water safety response.
Our POU Filtration Program
Emergency Response Deployment
Rapid mobilization and installation of POU filters across all at-risk fixtures following a positive Legionella test or regulatory directive — sinks, showerheads, and ice makers.
Healthcare Inventory Programs
On-site filter stocking programs for healthcare facilities that enable same-day response to positive Legionella results without waiting for emergency procurement.
Full Fixture Coverage
Filters installed at every point-of-use fixture in the affected area — patient room sinks, showerheads, ice makers, and any other fixture with direct patient or occupant contact.
Certified 0.2-Micron Filtration
NSF-certified filters with 0.2-micron absolute pore size that physically remove Legionella pneumophila, other Legionella species, and waterborne pathogens from the water supply.
Change-Out Management
Scheduled filter replacement programs with full documentation — tracking installation dates, change-out intervals, and fixture-level records for regulatory and accreditation purposes.
Remediation Coordination
POU filtration deployed as part of a broader remediation response — coordinated with hyperchlorination, system flushing, and follow-up Legionella testing to confirm clearance.
