Actual dimensions and fit
Plusco's standard 20x25x4 filter measures 19.5 x 24.5 x 3.5 inches. That is half an inch under nominal in each dimension. Custom orders are cut to the exact size you enter.
A nominal 4-inch filter from another manufacturer may have different actual dimensions. Measure your old filter and check the cabinet's requirements. A deeper filter must not be bent, crushed or forced into a shallow slot.
Choosing the rating
Depth and MERV rating are different choices. Match the depth to the cabinet and the rating to your system's requirements. Read the MERV guide and consult your HVAC technician before changing ratings if compatibility is unclear.
Shipping and bulk orders
Florida shipping is free. Outside Florida, shipping depends on the destination and filter depth; check the calculator's rate table and the final charge at checkout.
