Waterproof Fan Kits – Multi-Speed 80mm & 120mm Fans for DIY Humidifiers

Durable, Fully Encased IP68 Fans Built for Wet, Humid Grow Environments

💨 Always Free Shipping on All Products — No Hidden Costs!

Ordinary fans corrode and quit in the wet air around a mist maker. The House of Hydro Waterproof Fan Kits are fully encased and IP68-rated — rigorously tested in salt fog chambers (using our own foggers!) against 13 other brands, and none come close on durability or performance. Use one to push and evenly distribute mist from your DIY humidifier through a grow tent, greenhouse, mushroom fruiting room, or reptile enclosure.

Choose 80mm for smaller setups or 120mm for larger spaces and higher airflow. Each kit includes a variable-speed controller that plugs into a standard 120V wall outlet, giving you precise control over airflow and mist distribution.
