An air circulation and/or purification device for recirculating air and/or removing contaminants from the air which includes a housing having a top with an opening for air intake and a bottom, a fan contained within the housing, and a plurality of air output vents contained within multiple sides of the housing near the bottom of the housing. The bottom of the housing may include a conical shaped portion extending inward from the bottom of the housing or other structures to assist in expelling air from the housing in at least two different directions. The device may also include one or more filters designed to capture and filter out different types of contaminants.

Chair actuator

An adjustable chair includes a base, a back support, a control on the base, a seat positioned on the control and an actuator housing supported on the base. The control mounts the back for tilting movement between a fully upright position and reclined position. A seat is pivoted to the base at a front end. The seat is also connected to the base by a plurality of locking plates. The chair includes a back stop subassembly, a back or seat tension subassembly, a seat tilt subassembly and a seat depth subassembly. The actuator housing is an elongated, tubular member having concentrically mounted controls or actuators at each end. At one end of the actuator, a rotatable actuator controls back tilt tension and a concentrically mounted, push button actuator controls the back tilt or stop position. At the opposite end of the actuator housing, a rotatable actuator controls seat tilt position and a concentrically mounted pivotal lever or button controls positioning of the seat to adjust the depth through the depth subassembly.
