Pack of 10 replacement filters and plastic diffuser cover for the ESON nasal mask. These filters slot in between the diffuser cover (included) and the front elbow of the mask. When in use, the cover and filter will reduce the sound level of exhaled air from your mask. It is recommended that you replace this filter every 2-3 months of usage.
