Introduction: DIY Humidifier
Do you need more humidity in a room? I built this humidifier to help keep my mushrooms happy, but this design would work for any of your humidity needs!
- small watertight box (ex: baby wipes container)
- bottle (with a diameter taking up less than half the top surface of your box
- evaporating surface (preferably a humidifier filter, but a sponge also works)
- electrical plug
- small computer fan (with a diameter taking up less than half the top surface of your box)
- electrical tape
- 9-volt battery
- battery to wire snaps

Step 1: Assemble Materials
Assemble the materials: fan, soda bottle, sponge, and watertight box with a lid
Step 2: Marking Up the Box's Lid
Trace out the cross-section of the soda bottle and the circular cross-section of the fan area that has air-flow
Step 3: Cut It Out
Cut out both cross-sectional areas with a jigsaw
Step 4: Electrical Work
Wire the computer fan to a plug
Step 5: Prepare the Bottle
Cut slots into the neck of the bottle, to allow water to escape when it is inverted.
Step 6: Check the Fit
Do a dry-assembly to check the fit
Step 7: Assemble the Elements
- Place the sponge in the box, under the fan-hole
- Fill the soda bottle with water
- Place the soda bottle in its hole
- Invert the lid and soda bottle over the box, allowing water to flow until it reaches equilibrium
- Place the computer fan over its hole
- Secure the Computer fan with screws
Step 8: Extra Advice
This is a very simplistic humidifier, and this instructable is ripe for modification.
The main issues with my humidifier were:
- It very inefficiently gobbled energy for an un-regulable amount of time. In future versions, I highly recommend adding a timed switch-off feature and some regulator of electricity consumption.
- Sponges make extremely mediocre evaporating surfaces. On one hand, they do facilitate evaporation. On the other hand, they are a breeding ground for bacteria and never dry out.
