The price of the filter will populate below and you’ll be able to add this custom size filter to your shopping cart.

Please note, you’ll need to make sure you input your filter size exactly as you need it as custom size filters are not eligible for return or refund. To measure your filter, take a tape measure and measure the width (short side) and the length (long side) and the thickness.
