Before making a purchase, users should understand the difference between "nominal size" and "actual size." Basically, while many options claim to be 20x25x5, the actual dimensions might vary by a few fractions of an inch. Check your existing filter to see what the correct size is for your HVAC unit, and then order one that meets those rather than just blindly assuming the listed dimensions will work.
