For the last 4 years I have been working on and patented a tool which allows a user (residential and commercial) to change an air filter located in the ceiling without the need of a ladder (20 seconds or less). A video can be seen at 123inventions.com page 14 under Contact Robert. This tool is also adjustable to reach over furniture and other obstacles. I am in the process of getting investors to start producing this tool. I would greatly appreciate feed back, concerns and investor interest.
