Product Overview

With an ultra-modern tower design, the Stadler Form Hera Ultrasonic Humidifier boosts your indoor comfort while complementing your unique décor. Designed to humidify spaces measuring up to 760 square feet, this 3-gallon ultrasonic cool and warm mist humidifier boasts sleek housing along with a full range of features that make humidifying your space simpler than ever. Building on its large capacity, the Stadler Form Hera features two operating modes, multiple speeds, a demineralization cartridge, electronic controls, and much more.  

Choice of Cool or Warm Mist Operation

The Stadler Form Hera Humidifier helps you stay healthy and comfortable during the winter months and any time during the year when you need a boost in humidity. Using ultra-quiet ultrasonic humidification technology, this tower humidifier provides a steady stream of cool or warm mist to suit your preference and comfort level. To get warm mist, activate the independent pre-heating function and enjoy a soothing heated mist that won't cause uncomfortable drops in room temperature. To enjoy cool mist, operate the humidifier without the pre-heating function and experience fresh, room-temperature mist that eases your breathing passages and eliminates uncomfortable static electricity.

Two Operating Modes

The Stadler Form Hera Ultrasonic Humidifier by Swizz Style offers two operating modes to ensure that you always maintain a comfortably humidified space. In automatic mode, the humidifier can be programmed to automatically maintain your desired humidity level. Using the digital controls, simply program your desired humidity level in the range of 40% to 70%. The Hera's onboard humidistat and hygrometer will continually measure your humidity and adjust operation automatically to maintain your selection. Once your desired humidity level is reached, the humidifier will automatically shut off, saving valuable energy.

Alternatively, the Stadler Form Hera Ultrasonic Humidifier can be operated continuously to provide nonstop humidity to combat dry, wintry air. In this mode, select from three moisture output speeds for a subtle to quick boost in room moisture any time it's needed.

Additional Convenience Features

Along with automatic and continuous humidification, the Stadler Form Hera Humidifier boasts a variety of useful convenience features that help simplify day-to-day operation. These include:

  • Bidirectional Diffuser: Direct mist exactly where you need it with the bidirectional output diffuser.

  • Tank Refill Indicator: Always know when it's time to refill the humidifier by keeping an eye on the tank refill indicator. The Hera Humidifier also features a transparent water tank so you'll always know where the water level stands.

  • Tank Carrying Handle: Easily handle and refill the tank with the help of the handy tank carrying handle.

  • Night Mode: Maintain comfortable humidity even in the nighttime hours. In this mode, the humidifier's display lights are dimmed and humidity is set at 45%.

  • Demineralization Cartridge: This cartridge features a powerful ion exchanger to help remove mineral content in the water and prevent harmful white dust. It lasts up to 3 months, depending on your water's hardness.

  • Hard Water Test Strips: Use the handy water testing strips to test your water for hardness. The results will help you better estimate the life of the demineralization cartridge.

  • Ionic Silver Cube – This patented insert helps inhibit the growth of mold, mildew, and bacteria inside the humidifier so it produces only clean, fresh moisture.

  • Quiet Operation: Ultrasonic humidifiers are among the quietest humidifiers on the market. They use ultrasonic vibrations—with a sound frequency higher than a human can hear—to create a fine mist of water droplets that is quickly absorbed into your air.

  • MET-Compliant: The Stadler Form Hera Humidifier meets MET safety and performance regulations.
