Abstract: A portable vehicle humidifier includes an enclosed container with a removable cover, the cover having a plurality of apertures formed therein to permit humid air to be released from the container. A fan is mounted over a large opening in the cover to blow air into the container. A liquid-absorptive pad is positioned within the container to prevent excess movement of water in the container, and to slowly release water vapor into air blowing across the pad. A slide plate positioned over the large opening permits adjustment of the air through the container, and the volume and velocity of humid air exhausted from the container.
