The insides of Evapolar cartridges are made from non-organic basalt fibers, which prevents mold and bacteria from growing.
However, as cartridges filter impurities out of air and water, they can begin looking like the ones in the picture with time. There is no need to panic, it's not mold.
- the white or grey fluffy residue on the cartridge is dust, filtered from air and water
- the cartridge can also become yellow if the water contains lots of iron
We recommend replacing cartridges every 3-6 months.
If the cartridge looks like the one in the middle, there is no need to replace it immediately. The good rule of thumb is checking if the device still cools normally. If its cooling capacity has diminished, you may want to consider installing a new cartridge.
If the cartridge looks like the one on the right, we recommend replacing it.
