Generally a good replacement filter. It comes with a protective pad that more or less helps fill the gap between the filter and the frame of the device. I give this filter 3 stars due to the quality and lack of quality assurance. The two filter bags cannot be opened, how should one describe it? There were traces of glue on the fabric of two bags, they were folded and glued in such a way that they could not be opened. I had to be very careful cutting through the glue for the pockets to work as intended. This resulted in a dot on a pocket being quite "thin" in the material, so I was concerned about the long-term reliability of this filter. The filter deserves 5 stars if it wasn't for the problem with the glue.
