The simple fix for dental chair water safety- Inline PureFlow®

Updated: Jan 7


Dental chairs may appear safe, but their waterlines often reveal a different story. Behind the polished surface, tiny pipelines can harbor biofilm, an ideal environment for bacteria such as Legionella and nontuberculous mycobacteria (NTM) to grow. 


Every time a scaler, drill, or cup filler is used, these pathogens risk entering the air and water that patients depend on. Traditional flushing or chemical treatments may offer temporary relief, but contamination often returns within days. 


For practices committed to patient safety, reputation, and compliance, a more reliable solution is needed. MWT’s Inline PureFlow® makes the difference by providing a simple, proven protection that ensures consistently safe water at the point of care.


How does unsafe dental chair water safety affect patients & staff?

Every dental appointment involves water. Whether through ultrasonic scalers, high-speed drills, or air/water syringes, these tools generate fine aerosols that patients and staff inhale. If the waterlines feeding them are contaminated, bacteria such as Legionella or nontuberculous mycobacteria (NTM) can be carried straight into the lungs. 


The risks of unsafe dental unit waterlines go far beyond technical compliance.

  • Contaminated waterlines can expose patients to serious respiratory infections, including Legionella-related illness.

  • Daily exposure to aerosols during treatments puts dental professionals at constant risk.

  • Noncompliance can lead to inspections, costly remediation, lawsuits, or even shutdowns.

  • A single water safety incident can damage years of patient trust and credibility.


The simple fix- MWT’s Inline PureFlow® filters

Routine practices like flushing or chemical disinfection can temporarily lower bacterial counts, but they rarely address the root problem- biofilm. Once biofilm forms inside dental waterlines, it becomes a persistent reservoir for pathogens. 


To truly protect patients, staff, and compliance requirements, dental practices need a consistent, certified protection against waterborne risks.


MWT’s Inline PureFlow® Blue & Red Legionella Filters are designed specifically for dental chairs to provide certified water safety.


  • Red Filter: Removes suspended solids and debris, protecting the waterlines and extending the service life of the ultrafiltration membrane.

  • Blue Filter: Equipped with a 0.08 μm hollow-fibre ultrafiltration membrane, achieving Log 8 (99.999999%) bacterial reduction. This significantly reduces pathogens such as Legionella, Pseudomonas, NTM, E. coli, and Salmonella.


Inline PureFlow® delivers safe drinking water from cup fillers while reducing aerosolized contamination from handpieces and instruments. Installed at the T-junction of the chair, it safeguards every point of use.


Independently tested and compliant with U.S. and international standards:

  • ASTM F838-2020 for Log 8 bacterial reduction

  • NSF/ANSI and ASSE 2011-2022 standards, certified by IAPMO

  • EPA WaterSense recognized

  • Tested to ASHRAE performance criteria

  • CE marked and compliant with EU Drinking Water Directive (2020/2184), DIN EN 16421 & 58356

  • EPA FIFRA-registered establishment (No. 105402-NLD-1)


By combining both Red & Blue filters, Inline PureFlow® provides stronger protection, longer service life, and reliable water safety, giving dental practices confidence in every procedure.


How does Inline PureFlow® protect dental practices?

MWT’s Inline PureFlow® gives dental practices a simple, reliable way to protect every dental chair. By integrating directly into the waterline, it ensures:

  • Consistently safe water: Delivers safe water for both patients and staff, procedure after procedure.
