Point of Use (POU) Legionella Filters FAQ

What are the benefits of POU filters?

Point of use (POU) filters help remove Legionella and other waterborne pathogens just before the water reaches the open air, preventing a person from being exposed to the pathogen. The filters provide Legionella control at the fixture, such as a sink faucet or shower, making them a fast, easy-to-use, and cost-efficient option for controlling Legionella, making them useful for prevention, remediation, and ongoing mitigation. 

What is the typical application of POU filters?

POU filters are installed at the end of a fixture, such as at the end of a faucet or showerhead, or they can replace the fixture itself in some cases. They are often used during Legionella outbreaks, when water tests show elevated Legionella levels, or when a facility needs immediate protection from Legionella while evaluating longer-term Legionella control options. 

What types of buildings and areas use POU filters?

POU filters are commonly used in hospitals, nursing homes, jails, prisons,  dialysis centers, operating rooms, oncology wards, and other healthcare environments where infection control is critical and the user population has weakened immune systems. They are also used in lab areas, food and beverage systems, drinking fountains, sinks, hand washing stations, and shower applications where waterborne pathogen control is needed.

How do POU filters compare with POU (Point of Use) inline filters, POE (Point of Entry) filters, and FDA-cleared POU filters?

• POU filters: Are installed at the point where water is used, such as a faucet or shower, to provide immediate control of Legionella and other waterborne pathogens right before delivery to the user.
• POU inline filters: Installed inline on a specific outlet, branch line, or device and can provide effective retention of bacteria, viruses, cysts, Legionella, and other waterborne bacteria, often with high flow, high capacity, and low pressure loss.
• POE Filter: Help reduce Legionella and other waterborne pathogens at the point of entry (POE) before they are distributed throughout the building’s water.
• FDA-cleared POU filters: Evaluated for infection control in healthcare environments and commonly used in high-risk patient-care areas where validated filtration performance and regulatory confidence are important.
