The BRUNE B 600 Professional Humidifier requires either a Bio Filter or a Foam Filter for evaporative humidification, but not both.
Both filters support efficient humidification, but they differ in durability and recommended operating conditions.
BRUNE Bio Filter: Designed for efficient evaporative humidification and environmentally responsible operation. It can be disposed of with regular waste and should typically be replaced every 2–3 months.
BRUNE Foam Filter: A highly durable, cotton-reinforced evaporative filter designed for extended service life. It is particularly recommended for areas with hard water or high levels of airborne impurities and should typically be replaced every 3–6 months.
Both filters are compatible with the BRUNE B 600 and B 500 Professional Humidifiers. The best choice depends on water hardness, environmental conditions, and maintenance preferences.
