I have the dehumidifier all unpacked and ready to go. The instructions are very clear that I should let it sit upright, undisturbed, for 24 hours after unpacking, so that is what I am doing.
I hope this makes a huge difference for me. I have been using a unit my mom bought 20 years ago. It does the job, but it's very noisy.
The new one is far more powerful than that one, so life may improve chez moi!
