An air filter having an improved structural support. A pleated air filter having a plurality of truncated pleat tips and sloping side surfaces along a front face and rear face. The truncated pleat tips are orientated perpendicular to the direction of pleating. A reinforcing support member oriented in the direction of pleating and substantially contouring and connecting to the face of the pleated air filter and thereby having truncated pleat tips orientated perpendicular to the direction of pleating. A reinforcing strip connected to the truncated pleat tips of the reinforcing member along the face of the air filter and another reinforcing strip located on the opposite face of the air filter and connected to the truncated pleat tips of the filter to form a truss structure.
