Assessment of the microbial burden of water-bearing medical devices is becoming increasingly strict. After only a few weeks of operation a biofilm forms in every water-bearing system, even in instantaneous water heaters, encouraged by the slow flow of water, long periods of disuse and temperatures
around 38°C. This can lead to rapid bacterial invasion of the equipment, in some cases with Pseudomonas and Legionella in concentrations > 107/ml.

Otopront has taken this hazard seriously even years ago and developed a solution for all water-bearing devices. The water filter unit, the same model as used in the Otopront ENT treatment units, has been tailored specially to the user's requirements:

• simple to use
• economical
• high level of hygiene safety

With a retention rate of 0.2 μm the autoclavable filter unit ensures that only hygienically pure water reaches the patient. The water handle and hose are also completely autoclavable to prevent retrograde microbial contamination.

Unlike many other approaches, this unit completely maintains scientific standards even in long-term use.
