I was initially planning to purchase the 50 pint, but I'm glad I went with the maximum capacity. I have a high-humidity small/medium room I'm primarily using it in and I'm consistently impressed by the volume of water it is pulling out of the air. I do move it between rooms, and it can be a little big and heavy to get up and down stairs, but it's well worth the effort for the impact that it has. Highly recommended!
