A water recycler is designed to recycle waste water from a drip-type humidifying system. A water reservoir is provided with an opening to accept a drain line from the existing humidifier system. Additional fresh water is added into the reservoir to maintain a preset level via a float valve. The system is further provided with an internal pump which is activated by an existing furnace switch. The pump draws water from the reservoir and supplies it to the humidifier for reuse. As water is consumed by the humidifier, it is replenished by the fresh water system to ensure an adequate supply of water at all times.
