Our take on the Mini Cool Mist humidifier

The Honeywell HUL525B is a compact cool-mist humidifier for desktops, nightstands and small rooms up to about 162 square feet. It holds 1.5 quarts, runs on a single output setting, and has an adjustable humidistat plus auto shut-off. It is a simple, quiet option for a bedroom or office, but it lacks a low-water indicator, antimicrobial coating and app control, which many rivals at this size include. Owners rate it well for its small footprint and visible mist.
