Dehumidifier acts ware wonders

We live in a basement apartment and have some mold, by a humidity measurement, we found that our humidity always varies between 80% and 85%, which is denfinitiv too high. Despite airing and all Andren humidity did not go down. Then I put on these dehumidifiers and I'm pretty impressed when we now measure is the humidity at around 60% and the tank fills up continually, so I can only recommend it
