This Drip Cushion comes in one size only 24" X 24". Since your unit an odd size, you can cut a strip from the drip cushion and have it cover the entire top. The back is magnetic and will stay in place.

Is it safe to cover to the vents on top of the air conditioner?

There are vents on the sides as well, so I wonder if those vents are enough. Or will the magnetic cushion impede the air flow and overheat the unit?
