Abstract
Pool covers embodying the invention are formed of a very dense mesh material which ensures substantially one hundred percent shade while allowing water to pass uniformly through the cover and which is adequately strong to support the weight of an adult. The pool cover is formed of plastic fibers which are interwoven to form a dense mesh which is then subjected to a pressure and heat cycle to ensure that the resultant material has the requisite properties for allowing water to pass through at a desired rate (e.g., 0.1 to 5 gallons per square foot per minute) while blocking light (e.g., 100% shade). Thus, a self-filtering safety pool cover is formed which allows for water to pass through uniformly across its surface while blocking sunlight.
