How often should I change the filters in my evaporative humidifier?

Cleaning and replacing your filters is essential to ensure the proper functioning of your humidifier. There is no strict indication on this subject because everything depends on the type of room, humidity and temperature. On average, a filter should be changed every 2 to 3 months to prevent the proliferation of algae, bacteria and viruses, as well as their diffusion into the ambient air.
