There are three major categories of furnace filters; 16x20x4 MERV 11 Furnace Filters is one of them. These filters are usually made of fiberglass or synthetic material like polyester. They trap particles in the air by providing a barrier that is large enough for them to enter but small enough for clean air to escape. The most popular way to measure their efficiency is by measuring their MERV rating which tells how well they filter out different sized particles in the air.
