Understanding the crucial role of laminar flow devices in water safety and infection prevention.

In health care settings, water safety is critical and the risk of waterborne contamination is something we can’t overlook. Aerators mix air and water that create fine mist droplets.  These create a vehicle for dangerous bacteria, including Legionella. These droplets can easily be inhaled, putting patients and staff at risk for respiratory infections.

As we demonstrate in our video, an aerator has slots, and this is what allows the air to be pulled into the water stream and aerosolized.

Laminar flow devices look very similar to aerators, but they operate differently. Instead of mixing air and water, they deliver a smooth, solid stream of water, completely eliminating the aerosol effect. By preventing the formation of mist and splashing, laminar flow devices drastically reduce the risk of airborne contamination.

In addition to infection control, they help maintain controlled water flow and minimize splashback that could cause slip hazards or water pooling in sink basins—both of which can harbor additional bacteria.

Hospitals typically use two types of faucet spouts:

• Threaded spouts that allow for the easy installation and maintenance of laminar flow devices at the tip of the faucet.
• Non-threaded spouts, where the flow control occurs internally at the base.

Over time, sediment and debris from plumbing systems can accumulate in these components; especially after water system disruptions such as maintenance or plant shutdowns. When the flow control is built into the base, it’s much harder to clean. However, with end-point laminar devices, any sediment buildup can be easily removed to maintain proper flow and hygiene.

Using non-aerating laminar flow devices provides a safer, more efficient water solution that protects both patients and healthcare workers. When combined with routine fixture maintenance and water management practices, hospitals can greatly reduce the risk of Legionella growth and other waterborne pathogens.

At Water Saver Solutions, known as The H₂ROI People, our FixtureCare Program helps healthcare organizations:

• Reduce Legionella and bacterial risk

• Protect patients and staff

• Maintain ASHRAE 188 and 514 compliance

• Simplify maintenance with our app-driven, proactive service model

Through safer fixture design and regular maintenance, facilities can take a proactive stance on water safety, improving both compliance and patient outcomes.
