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.

• Cold steam: tap water, mineral water and distilled water are suitable. If your water is hard, a white deposit will form around the device. This is the limescale in the water breaking into tiny particles and falling back down next to the device. There is no risk to your health, however, you must ensure that you clean your humidifier well so that it does not scale up. It is also possible to use a mixture of tap water and mineral water. To reduce this white dust, it is advisable to regularly replace the humidifier's filter cartridge.

• Warm steam: tap water, mineral water and distilled water are suitable. Just like hot steam humidifiers, water from a softener is strongly discouraged.

• Hot steam: tap water is suitable, but softened water from a descaling system using salt should be excluded. The boiling point of the water will be transformed, causing an overflow and then a deformation of the humidifier.

• Evaporator: any type of water. Ideal if the water is very hard. The hard water will remain at the bottom of the tank and can simply be cleaned with a suitable product (white vinegar for example).

Yes, with this type of humidifier you can use any type of water.

Frequent use of a humidifier requires regular and careful maintenance, at least once a week if you use it very often.

To clean it, use white vinegar: in addition to being economical, it is the ideal product for eliminating limescale. There are also specific maintenance products, such as the Stadler Form cleaner and descaler Cleaner&Descaler which effectively preserves materials.

We recommend filling the tank with vinegar and water, then leaving it to act for 30 minutes before rinsing it. Just be sure to unplug it first and not wet the electronic components so as not to damage them and put yourself in danger.

In the case of an ultrasonic humidifier, clean the metal plate with a soft brush.

Finally, do not let water stagnate for more than 72 hours in the device to avoid any proliferation of bacteria.

A slight yellowish or brownish discoloration may appear on your filters. This is caused by impurities in the water or air. The poorer the water quality, the faster the filter will become discolored. This discoloration is normal and harmless as long as it is not caused by mold. The discoloration will also not affect the performance of your humidifier.

Both devices work by evaporation. The air washer works with washable discs, while the evaporator works with filters (also called cartridges) that must be replaced regularly. The difference is that the air washer does not need consumables and its filtration quality is better.
