Firstly, the motor filters provided to me did not fit the UltraOne model. The original dimensions of the filter are 11x14cm. These were 11 cm squares. Second, these filters were twice as thin as the original filter. Third, the mesh used in these filters is much more open and porous than the original. I could literally see through them at some points. Don't waste your money on this product. I have no doubt that Electrolux will ever approve a crappy quality filter replacement like this. If you care about your vacuum cleaner motor, look elsewhere.
