The Keystone 22-pint dehumidifier is a compact compressor unit rated to pull moisture from rooms up to about 1,500 square feet. It has a built-in humidistat, a timer, auto shutoff when the bucket fills, and a washable filter, so it can run unattended for stretches. It has no Wi-Fi or app control, which keeps it simpler and cheaper than smart rivals. Owners of small basements, crawl spaces and damp bedrooms find it does the job, though it is not the quietest or fastest-draining unit in its class.
