For a room with very high humidity (70 to 90% 14m2 while the system is planned for 40) in one month, I still have not finished the two supplied cartridges (that must be installed both at the same time in the system) and the humidity has not really decreased (-3% on average).
The blue color of the water recovered and the many precautionary information on cartridges that are very little confidence in the product's environmental impact and we are sorry to throw everything down the drain.
Totally unique to an electric dehumidifier, which better fulfill the task announced on surface and be cheaper from 6 months.
Ultimately, I do not redeem cartridges when they run out.
