The water trap or condensation trap is a product that functions as a condensation filter, capturing water vapor from the oxygen tubes before it reaches the patient undergoing oxygen therapy. It is resistant to the rigors of long-term daily use. The transparent plastic allows easy visual inspection of accumulated fluid buildup to assess the need for cleaning or replacement. The ends of the water trap offer easy connection to the oxygen tubes and the extension (3m or 7m) for maximum freedom of movement.
