Abstract
The present invention advantageously provides an inexpensive and disposable drain filter that includes a first annulus, a second annulus, a filter layer, secured between the first and second annuli, to filter particulates from a fluid, and an adhesive layer, disposed on the lower surface of the second annulus, to temporarily secure the second annulus to a surface exposed to the fluid. The filter layer may form a dome above the upper surface of the first annulus.
