Recommended Systems for Walk-In Humidors
If you already know the approximate size of your walk-in cigar room, this page makes it easy to choose the right Sonic Humidifiers system. Below you’ll find a quick comparison of our recommended models for walk-ins and large cigar rooms, plus guidance on when to use multiple units.
For a step-by-step explanation of sizing, see our Walk-In Humidor Humidification Buying Guide, and if you’d like help calculating cubic footage, use our Walk-In Humidor Sizing Calculator.
Quick Recommendation Table
Use this table as a starting point. All ranges below are approximate and assume a properly built cigar room.
| Room Size (Cubic Feet) | Recommended Sonic System | Notes |
|---|---|---|
| Under 500 cu ft | Contact Us | Small rooms and unusual layouts are best sized with our help. |
| 500 – 1,800 cu ft | Wall Mounted Humidifier | Ideal range for most walk-in cigar rooms using the wall-mounted system. |
| 1,800 – 2,000 cu ft | Wall Mounted Humidifier or SH1 | Upper end of wall-mount range and lower end of SH1. Choose SH1 if you want extra capacity or expect higher traffic. |
| 2,000 – 4,000 cu ft | SH1 or SH3 | SH1 works well in many rooms in this range. SH3 is preferred for larger or high-traffic rooms where fast recovery is critical. |
| Over 4,000 cu ft | Multiple SH-Series Units | Use two or more SH1/SH3 units for proper coverage, reduced workload, and built-in redundancy. |
These recommendations are general guidelines. Construction quality, insulation, door frequency, and local conditions can all affect final sizing.
System Overviews
Wall Mounted Humidifier — 500 to 2,000 Cubic Feet
The Wall Mounted Humidifier is our go-to solution for small to medium walk-in humidors. It mounts on the wall for excellent airflow and easy service access.
- Recommended room size: 500 – 1,800 cu ft (up to ~2,000 cu ft in some cases)
- Best for: small retail walk-ins, private cigar rooms, back-room storage humidors
- Benefits: clean installation, reliable output, straightforward maintenance
SH1 — 1,800 to 4,000 Cubic Feet
The SH1 is a high-output ultrasonic system designed for larger walk-in humidors and commercial cigar rooms that need dependable, continuous performance.
- Recommended room size: 1,800 – 4,000 cu ft
- Best for: busy walk-ins, strong daily traffic, larger private collections
- Why choose SH1: excellent balance of output, efficiency, and capacity
SH3 — 2,000 to 4,000+ Cubic Feet
The SH3 is our maximum-output system for large or high-demand rooms. It is ideal when you want fast recovery after door openings and extra headroom for challenging environments.
- Recommended room size: 2,000 – 4,000+ cu ft
- Best for: cigar lounges, large retail humidors, rooms with frequent door openings
- Why choose SH3: highest single-unit output, excellent for demanding commercial setups
Multiple SH Units for Rooms Above 4,000 Cubic Feet
For very large cigar rooms and walk-in humidors above 4,000 cubic feet, we recommend using multiple SH-series units (SH1 and/or SH3). This approach offers several advantages:
- Proper coverage: large rooms need more than one source of humidity to avoid dead zones.
- Reduced workload: each unit runs less, which can improve reliability and longevity.
- Built-in fail safe: if one unit ever needs service, the others keep the room in a safe range.

What About Cabinet Humidors?
Our Cabinet Humidifier is designed specifically for cabinet-style humidors and lockers, not full rooms. If you are outfitting only a cabinet or series of cabinets, that system is usually the right fit.
For walk-in cigar rooms and cigar lounges, we recommend the Wall Mounted Humidifier, SH1, SH3, or multiple SH units as outlined above.
