Brune B300 evaporative filter

the Brune B300 evaporative filter mat with zip is designed specifically for the Brune B300 humidifier. Replace filters at least once a year, or more frequently if you live in a hard water area. If you notice dropping humidity levels or unusual odors from your humidifier, check the filter first as these symptoms typically indicate it needs replacement.

Replace all humidifier filters annually at minimum, adjusting frequency based on usage intensity, environmental dust, and local water hardness.

Please note: filters should not be washed.
