This item replaces a 70 pt model and is adequately removing humidity from my basement. The redesign on the filter is an improvement in facilitating cleaning. The filter is now removable from the filter casing and is much easier to clean as a result. The vertical outlet for dehumidified air rather than the horizontal discharge in the previous model also aids in the flow of dehumidified air into the basement area. I am quite pleased with the operation of this 50 pt model.
