65 percent humidity is considered high and the environment inside your house is going to be most comfortable when you maintain the humidity levels at around 30 to 50 percent. When the humidity level goes beyond 60%, the air becomes too wet that can be dangerous for both the homeowners and the house itself.

Where should you place a dehumidifier?
To use your dehumidifier, put it in the most humid room in your house, like the bathroom, laundry room, or basement.

A fan itself won’t really help with the humidity levels in your cellar, but it will help with getting air moving into the room from other areas such as the rest of the house and outdoors.

Do dehumidifiers use a lot of electricity?
Let’s take a standard model that operates at 280 Watts-hour. If the current power rate is 15 cents/kW, an electric dehumidifier uses 4.2 cents of power per hour. Therefore, if you run it for 10 hours a day, the cost is 10 hours * 4.2 cents = 42 cents/day or about $153.30 per year.
What humidity grows mold?
Sometimes, humidity or dampness (water vapor) in the air can supply enough moisture for mold growth. Indoor relative humidity (RH) should be kept below 60 percent — ideally between 30 percent and 50 percent, if possible. Low humidity may also discourage pests (such as cockroaches) and dust mites.
Where should dehumidifier be placed in basement?
If you are using a relatively small dehumidifier for basement with little moisture issue then it is perfectly fine to place it on the floor.

Does a dehumidifier make a room warmer?
To be clear, dehumidifiers are designed to remove moisture from the air, not cool it. There’s also some additional heat generated by the dehumidifier’s air compressor. The overall result is that the air going back into the room might be warmer than it was going in, usually around 10 to 15 degrees.
