G.A.S SonicAir Humidifier - Affordable 10L Ultrasonic Humidifier for Small to Medium Rooms
Best for: growers with a small to medium grow space, roughly up to 3m x 3m, who need an affordable way to raise humidity during the vegetative stage.
Our thoughts
This is the entry-level SonicAir - a straightforward ultrasonic humidifier with a decent 10 litre tank, rather than the mains-fed, higher-output SonicAir Pro. If your room's on the smaller side and you just need to stop things drying out during veg, you don't need the Pro's continuous water feed or its much higher output - this covers it for a lot less money.
The G.A.S SonicAir Humidifier from Global Air Supplies is an ultrasonic humidifier designed to add moisture to the air in small to medium grow spaces. When your room runs too dry, growth rates slow down - getting the humidity balance right matters most during the vegetative stage, when plants are putting on the most growth.
It uses a 10 litre water tank and produces mist through four multi-directional spouts on top of the unit, with a maximum output of around 800ml per hour. The ultrasonic membrane is made from a titanium and ceramic alloy to extend its working life, and the unit switches itself off automatically when the tank runs dry. It runs at under 35dB, so noise isn't a practical concern even in a small space, and a control knob lets you adjust mist output to suit your room.
How it compares
The standard SonicAir is positioned as the budget, tank-fed option in G.A.S's humidifier range.
- Versus the G.A.S SonicAir Pro: the Pro produces up to 6.5 litres of mist per hour from a continuous water intake rather than a 10L tank, aimed at larger rooms needing sustained output.
- Versus AC Infinity's CloudForge T3: the CloudForge offers a smaller 4.5L reservoir with app-based VPD control; the SonicAir trades smart connectivity for a larger tank and simpler manual operation at a lower price.
- Versus running a standalone domestic humidifier: purpose-built grow room units like the SonicAir are designed to pair with humidity controllers for automated on/off control, which most household humidifiers aren't built for.
For a small to medium tent, the standard SonicAir's tank capacity and low running cost make more sense than stepping up to the Pro.
Usage guidance
Setup is simple tank-fill operation.
Filling and positioning
Fill the 10 litre tank and position the unit so its four spouts can distribute mist across the room without soaking nearby foliage directly.
Adjusting output
Use the control knob to set mist output to suit your room size and current humidity reading.
Automatic control
Pair with a G.A.S humidity or VPD controller for automatic on/off switching rather than running the humidifier continuously.

Our take
The standard SonicAir does exactly what a room this size needs - enough tank capacity to not need constant refilling, quiet running, and a sensible price for what it does.
One we sell a lot of for new growers setting up their first proper humidity control. Worth picking up if you want equipment you can rely on.
