Why it's worth it
The Waykar is the lightest and smallest unit here at under 29 pounds, and it's rated to keep working down to 41°F. Owners consistently call it quieter than the dehumidifiers it replaced, and Waykar's customer support comes up again and again in a good way.
At 28.6 pounds this weighs roughly two-thirds of what our top pick does, and it's the shortest unit in the lineup. If you need to carry a dehumidifier up basement stairs, or tuck it into a corner where a 24-inch-tall machine won't fit, that difference is the whole decision. Owners who've owned several dehumidifiers over the years describe this as both the quietest and the lightest they've had.
The cold-basement features are the real argument here. Auto-defrost is rated down to 41°F, which covers the kind of unfinished basement that stays chilly into May. A self-drying cycle runs after shutdown to dry the internal components, which helps keep the inside of the machine from becoming its own mold problem. Most units at this size don't state a low-temperature rating at all.
