Oasis Humidifier for double bass

The Oasis humidifier is characterized by its large capacity. The container is filled with the supplied syringe and hung in a ƒ-hole. The moisture is gradually released into the air through the mesh; one filling lasts for 2-3 days. The screw cap closes the container securely and prevents moisture damage caused by leaking water.
The Oasis humidifier is around 32 mm thick – a sufficiently large ƒ-hole is therefore a prerequisite for use. For a long service life, the manufacturer recommends using distilled water.
