Keep mist output consistent inside your Sonic Air Pro
The Sonic Air Pro Sponge is a small internal component that regulates water movement inside the Sonic Air Pro humidifier, feeding the ultrasonic disks so they produce a steady, fine mist rather than an erratic one. When it wears or clogs, mist output drops and grow room humidity starts to drift, which dries the air and slows transpiration and nutrient uptake. Swapping in a fresh sponge is a quick way to restore reliable internal water flow and keep humidity stable through veg and flower.
Key Benefits
- Direct replacement sponge for the Sonic Air Pro humidifier
- Consistent internal water flow to keep the ultrasonic system fed
- Reliable mist production for steadier humidity control
- Quick to fit as part of routine humidifier maintenance
- Suits hydro, coco and soil indoor growing setups
How to Use
- Turn off and unplug the Sonic Air Pro before any maintenance.
- Open the unit following the manufacturer's maintenance instructions.
- Locate the sponge in the internal water distribution area and remove the old one.
- Fit the new sponge and reassemble the unit.
- Refill with RO water before restarting.
