Point of Entry (POE) Legionella Filters FAQ

What are the benefits of POE filters?

• Point of Entry filters, also called POE filters, help reduce Legionella and other waterborne pathogens before they are distributed throughout the building’s water.
• They provide broad, building-wide protection from a single treatment location.
• They can be configured as filtration only, or as part of a multi-barrier disinfection system

What is the typical application of POE filters?

POE filters are installed where the building’s water supply enters the facility to treat incoming water, addressing the problem at the source. They can also be placed after water softeners, which can be a source of bacterial growth.

What types of buildings use POE filters?

POE is commonly used in facilities in which at-risk individuals may come into contact with the water, such as hospitals, nursing homes, surgery centers, transplant centers, dialysis centers, hotels, resorts, manufacturing facilities, office buildings, and condominiums.

How do POE filters compare with POU (Point of Use) filters, POU (Point of Use) inline filters, and hot water Legionella control filters?

• POE: Treats water at the building entry point for broad coverage across the facility.
• POU: Protects at the fixture, such as a sink or shower, by filtering right before the water is delivered to the user.
• POU inline: Protects a specific outlet or device on a branch line, often used for equipment and targeted points.
• Hot water Legionella control filters: A specialized POU filter designed to eliminate Legionella from water in hospitals, nursing homes, and other healthcare environments.
