Design and Build Quality
JET lists the actual dimensions of the filter at 289mm by 595mm by 22mm, which converts to about 11.378 by 23.425 by 0.866 inches, alongside the nominal 24x12x1 inch sizing used for ordering. Buyers should use the nominal size when matching it to their AFS-1000B or AFS-1000C unit.

Alternatives Worth a Look
JET's electrostatic outer air filter combines a 5-micron filtration rating, direct compatibility with the AFS-1000B and AFS-1000C systems, and a 90-day manufacturer warranty in a nominal 24x12x1 inch size. It is a straightforward replacement pick for owners of those specific JET units, with the main tradeoff being that it will not fit any other air filtration system.
