We created Fan Sox to add color to our ceiling fans and provide a practical solution to getting our fans clean and free of dust and grime. Fan Sox are machine washable slip covers that fit snugly over each one of your fan's blades. They are sold as a set of five, and made with pride in the USA. Practical and durable, they fit most standard ceiling fans (19-22 inches in length, 5.5-6” in width) and keep your fans clean, colorful and super cool!
