Sonic Air 23L Humidifier Float Kit

Automatic top-up so your humidifier never runs dry mid-cycle

The Sonic Air 23L Humidifier Float Kit connects the Sonic Air 23L humidifier to an external reservoir using standard garden pipe and hose connectors, so the float valve keeps the humidifier topped up automatically instead of needing constant manual refills. That means uninterrupted humidity through veg and flower, and it doubles neatly as a float valve for a DIY hydroponic header tank wherever automatic water-level control is useful.

What's Included

• Float valve for the Sonic Air 23L Humidifier

Key Benefits

• Automatic refilling from an external water reservoir for continuous running
• Reduces manual refilling in busy grow rooms
• Holds stable humidity without the drop-off when a tank empties
• Simple installation using standard hose-end connectors and garden pipe
• Doubles as a header tank float valve for DIY hydroponic setups

Humidity crashing when the tank empties?

A humidifier that needs frequent manual refilling will run dry between checks, and a sudden humidity drop stresses young plants and stalls transpiration and nutrient uptake. Fed from a connected reservoir, the float valve holds the correct water level so the unit keeps running and humidity stays steady.

How to Use

1. Fit the float valve into the connection point on the Sonic Air 23L humidifier.
2. Connect a garden pipe to the valve with a hose-end connector.
3. Attach the other end to your water reservoir or tank with a second connector.
4. Position the reservoir higher than the humidifier so water flows correctly.
5. Check all connections are secure to prevent leaks; the valve then maintains the level automatically.
