Hello Ann, this is JK. I understand that you are looking for the location of the filter in a dehumidifier. Generally, you will need to remove the bucket to be able to reach under to remove the filter. Please refer to your owner's manual for more detailed care and cleaning instructions. Hope this helps!

Don, unless your dehumidifier is a Low temperature model, that very well may be the problem.
The air temp in a basement at floor level is colder than that chest level. Dehumidifiers don't work well at temperatures at 40 degrees F or less. Raising the unit up off the floor on to a sturdy table, counter top, etc, that is strong enough to handle it's weight, plus a full tank of water, will generally solve the problem. The higher up you can safely put it, the better. Also, lower the humidity extraction level to 35%. As 50% is just not low enough in a basement application.

Hope this helps you to solve the problem.
