ASSE International Publishes New Listing Evaluation Criteria for Legionella Reduction and Treatment Devices

ASSE International has published a new Listing Evaluation Criteria standard — ASSE LEC 2011-2022, Product Performance Requirements for Legionella Reduction and Treatment Devices.

Legionella reduction and treatment devices are designed to reduce legionella microorganisms found in potable water systems. These devices reduce the number of the bacteria through inactivation and/or filtration. They can reduce or prevent the downstream bacterial colonization of a water system and thus ultimately the release of the bacteria into the water.

Devices are intended to be used at the point of entry or point of use in applications for hot or cold water, or both, for drinking water, washing hands or showering. This standard defines the performance requirements for those devices. Learn more at asse-plumbing.org.
