I replaced the original Sears filter on my Kenmore Whispertone canister vacuum with this filter. This is an exact replica but much cheaper than the Kenmore part. In this kit you get two filters (two thin white pre-filters and two thicker black ones). Remember to install the white filter on the bag side and the black filter on the motor side. Will buy this again and recommend this filter as a direct replacement for the original Kenmore filter that comes with the Whispertone cylinder vacuum.
