Sometimes when using a new oxygen suction tube, it may emit an odor that is caused by the materials used in the manufacturing process, such as the silicone and ABS plastic tubes. However, there is nothing to worry about as this is a normal occurrence, and the smell is not harmful to our health. It will eventually dissipate on its own.
If the oxygen suction tube is not new, it could be due to neglecting to clean or replace the water in the humidification cup for an extended period. This neglect can lead to an unpleasant odor in the cup. However, by thoroughly cleaning both the humidification cup and the oxygen suction tube, you can effectively eliminate the odor.
