Used this to dehumidify a storage closet in my basement (4x10)that had a musty smell. I wanted to prevent mold & mildew from growing on the canned goods and homebrew I had stored there. I ran it continuously and it worked well when it worked,filling the reservoir after about two weeks. Then it died after 16 month, phone Eva-dry and they told me they only warranty items for 12 months -the required (in the US) consumer warranty. So now I'm out $45+shipping.
