Measuring around 135 x 56mm, they could be used in the Fluval U2 but without the sponge Good design at a reasonable price, currently £10.59 for 6x filters ## Features - QUANTITY AND SIZE - Each pack contains 6 pieces, with each filter measuring 5.3 inches * 2.2 inches (135 mm * 55 mm), making it rich and easy to use.
