Helen of Troy Codml HUL525B Mistmate Cool Mist Humidifier

Product Description

The HELEN OF TROY CODML HUL525B is a compact, filter-free cool mist humidifier designed for small rooms. It produces a visible cool mist without the need for replacement filters, keeping operating costs low. The unit holds 0.50 gallons and delivers up to 24 hours of continuous run time on a single fill. Variable moisture output settings allow the user to dial in the right humidity level for the space. An auto shut-off feature activates when the tank runs empty, preventing dry operation. At 3.9 pounds, it is lightweight and easy to reposition. HVAC and indoor air quality professionals, as well as knowledgeable DIYers, will find this unit straightforward to service and maintain.

The HUL525B is suited for small residential spaces such as bedrooms, offices, and nurseries. The wide tank opening simplifies filling and cleaning, and a cleaning brush is included. A 180-degree directional mist outlet lets the installer aim output toward the area of concern. An essential oil tray is built in for optional aromatherapy use. This unit is intended for portable, tabletop placement rather than ducted or whole-home integration.
