The Hu-Friedy Waterline Filter is designed to help dental practices continuously deliver clean water to patients.

“Dental unit waterlines are known as notorious breeding grounds for bacteria, which can form into huge, persistent colonies of sticky biofilm. But traditionally, filters can be tricky to install, burdensome to maintain, and inconvenient to change,” said Jennifer Naylor, executive vice president at Hu-Friedy. “We set out to create a product that will help keep waterlines clean while requiring minimal effort from staff.” 

The Waterline Filter is registered by the Environmental Protection Agency in all 50 states as a microbial agent for use in dental unit waterlines attached to dynamic dental instruments. It reduces contamination and odor-causing bacteria to 200 CFU/mL or less, according to the company, exceeding the Centers for Disease Control and Prevention recommended level of 500 CFU/mL. The filter also is designed to provide ongoing, consistent, and accurate dosing to inhibit microbial contamination for up to a year.

Plus, the ready to use cartridge can be installed in five minutes and requires no daily, weekly, or monthly maintenance. Its universal design is the first of its kind to suit both municipal waterlines and independent water reservoirs, Hu-Friedy says. The filter is non-corrosive and doesn’t include silver or other hazardous materials, the company adds, so disposal is quick and easy.
