Ah yes, costco. I purchased my previous dehumidifier at Costco.
Frankly, I would buy the same brand if they still made it, but that is not the case.
Maybe they have more choice in the states, but there are only 4 models online at costco canada and they are pretty much all more expensive than the previous one I bought while also being under sized (compared to my previous choice).
The DeLonghi 23.7 L (50-pint) Dehumidifier looks ok, but it is only 50 pint and I don't know how much energy it uses...
