When you find the relative humidity (RH) going below the 30% – 50% range, you need to immediately switch off the dehumidifier. If there is too much dehumidification, say below 30%, it will result in the growth of several bacteria, mold, and dust mites that thrive in low humidity conditions.
However, drying time will vary depending on the amount of water damage, the size of the area, and the model. As a general rule of thumb, commercial dehumidifiers take between 24 and 48 hours depending on the size of the area. Household models will usually take at least a week to dry water damage.

Dehumidifiers that are not properly maintained can give off unpleasant odors. Dehumidifiers are designed to remove excess humidity from your home, but if they are not properly maintained they can acquire a musty smell that spreads throughout your home.
