• Actual Filter Size 16.5"x17.5"

• Some filter pads may have a Alummin target. That’s because the manufacturer switched to a cheaper carbonized mesh instead of using a full activated-carbon sheet. To make the pad work, they had to add a foil target so the electrode could make contact.
• Fast-Shipped-Filters stayed with the original full-carbon center design, which carries the electrical charge evenly across the entire filter. Because of this, no aluminum patch or painted target is needed—the electrode makes solid contact anywhere on the pad.
