The insides of Evapolar cartridges are made from non-organic basalt fibers, which prevent mold and bacteria from growing.
The color of the filter inside the cartridge may differ from white to gray and slightly yellow depending on the batch and conditions it was stored and shipped in but it does not affect its efficiency. Moreover, in 2021 we improved our technology of evaBreeze production, but it affected the color of the material so to some people it may seem used or dirty. This is a natural color of basalt: we don't use any chemicals, coloring, or bleach to whiten the material. This is to ensure our materials are environmentally friendly. Here in the picture, you can see the difference between evaBreeze produced in 2020 and 2021. In addition to the outstanding absorbent properties, this material, unlike the previous version, is completely devoid of any odor. Cartridge material tends to crumble a bit during transportation so sometimes you can find little grey particles on the bottom of the device. That is ok as they strengthen up after the first contact with water. |

As cartridges filter impurities out of air and water, they can begin looking like the ones in the picture below 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. A 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.
