Abstract: The room humidifier is convertible for use with either a wall register, baseboard heating unit, console type heating unit or steam radiator and includes a container portion adapted to hold a supply of water and an air deflector portion detachably connected to the rear of the container. The container is of substantially rectilinear construction with aligned front and rear openings spaced from the bottom of the container through which the air is adapted to pass. Water absorbent plates are disposed in the water container and extend into the space between the front and rear openings so that the air will pass over the plates. A latch device is provided for securing the container portion without the air deflector to a wall register or baseboard heating unit.

Abstract: The humidifier is comprised of a substantially rectilinear container having a water reservoir in the base thereof and aligned rectilinear openings in the major front and rear surfaces. The interior surfaces of the top and bottom walls of the container are provided with parallel spaced apart grooves for removably supporting a plurality of evaporator plates of absorbent material in parallel spaced apart relation to each other perpendicular to the aligned apertures in the front and rear surfaces. The plates have a configuration to facilitate their insertion and removal through the rear aperture and guide grooves are provided on the interior surface of the front wall beneath the aperture. A hook and quick release device are provided for detachably supporting the humidifier from a standard wall type hot air register.
