Product review (1 stars): These are very poor filters. The media is thin
These are very poor filters.  The media is thin.  This means they clog very fast from impurities in the water.  Other filters would last about 4 weeks before clogging.  These last 1 week at best.

The fit of these is OK.  However, because they are so thin, you have to be very careful in handling - they almost crumple as you are installing.
