A DIY humidifier cum ventilator

This is not my DIY project but an excellent idea I picked up during a recent trip to southern Thailand.

In essence it is a combination of ventilation & humidifier all-in-one. Like it immediately soon as I seen its construction and operation.

The bricks used in the wall construction have 4 extrusion holes each. A dripping tap keep the wall moist always (as seen in photo). In-coming air passes through the damp brick wall and pick up moisture. Excess water is drained off from the bottom water pool.















A very clever arrangement indeed! I give top marks to its originator!
