SH-4 High Output Humidifier

Maximum humidification for very large spaces.

The Sonic SH4 is our highest-output humidifier. It’s built for very large rooms and commercial spaces where a standard unit can’t keep up. It produces a very high volume of ultrasonic mist, so it’s meant only for spaces large enough to absorb that much output: walk-in humidors, large cigar lounges, retail floors, and similar commercial environments.

Output volume is approximately 1.25 Gal/Hour to 2 Gal/Hour depending on the setting of the output adjustment knob.

Built for continuous operation
The SH4 connects directly to a water line. There’s no tank to refill, and it can run around the clock without interruption, which matters in commercial settings where downtime isn’t an option.

Precise control with the Lite-F Controller
The SH4 works with the Sonic Lite-F Temperature/Humidity Controller (sold separately, required for operation). The Lite-F shows real-time temperature and humidity readings and has separate set points for each. Simple up/down controls make it easy to program and adjust.

Key Features

• Maximum mist output, designed for very large spaces
• Direct water feed for uninterrupted operation
• Commercial-grade construction
• Managed by the Sonic Lite-F Controller (required, sold separately)

Important: Because of its very high output, the SH4 is not recommended for small or medium rooms. If you’re not sure the SH4 is right for your space, contact us and we’ll help you choose the right unit.
