The Brune B500/B600 foam filter is designed specifically for the Brune B500 and B600 evaporative humidifiers. Replace filters at least once a year, or more frequently in hard water regions. If you notice dropping humidity levels or unusual odors from your humidifier, check the filter first as these symptoms often indicate it needs replacement.
Foam filters – While the Brune B600 evaporative humidifier usually ships with a standard paper filter, we always upgrade to a foam filter. Foam filters last longer and resist sagging in high-limescale areas. Replace all humidifier filters annually at minimum, adjusting frequency based on usage intensity, environmental dust, and local water hardness.
Please note: Never wash the Brune B500/B600 foam filter.
