Description The NUWAVE® ozone filter is an advanced filter designed with a large amount of impregnated activated carbon within the surface area of the internal adsorber of the filter. Once your NUWAVE® CPAP sanitizer completes its ozone sanitization cycle, the activated carbon filter will adsorb ozone and convert it into active oxygen over approximately 90 minutes. When the sanitization cycle is complete, simply remove your CPAP items and you are ready to use them. Filter lasts six months.
