Product review (1 stars): These filters do not fit the KAZ 3300 correctly.
These filters are not constructed like the original KAZ 3300 filters.  These are a continuous circle, and the originals were a single sheet that allowed you to tuck the two ends into a spot in the plastic guides.  I had to cut the circle and the full length was too short to fit properly.  When I tried it originally, the full circle was not long enough.  Also, the height of the filter was too high.  I had to push the lid down firmly to get the lid to close.  I am ordering from another vendor and hope I get the proper fitting filter this time.  Otherwise, I will need to order from KAZ next time.
