The mark consists of the words "Pro-Air" in green lettering centered above a design created by an artistic rendering of the letters "P" and "A" inside the outline of a green circle on the left. The top of the letter "P" is represented by a solid green circle and the bottom by a green pie-shaped figure with curved sides, with the top and bottom of the "P" having a blank space between them. The letter "A" is represented by a small green triangle above a green trapezoid with a blank space in between them representing the cross-bar of the "A." A hand extends from the right side of the circle. On the right, there is an image of the earth inside the outline of a green circle, with a hand extending from the left side of the circle. The two hands are joined together in the form of a handshake. The words "Pro-Earth," in green lettering, are centered underneath this image.
