Product review (4 stars): I dissected the original Samsung DA29-00020B Filter and Water Sentinel WSS-2
I dissected the original Samsung DA29-00020B Filter and Water Sentinel WSS-2.  The filter medium length of the two is the same as well as the outer diameter.  The inner diameter of the WSS-2 was larger.meaning the medium is thinner. i.e. less overall filter medium

The medium of the WSS-2 had a texture like compressed wood pulp and I was able to easily break it up.  The medium of the Samsung DA29 had a texture like a soft stone and was difficult to break up.

Going by filter medium look and feel the Samsung DA29 is superior.

Taste and smell- My family and I notice no difference in water taste or smell between the two filters although when the Samsung started reaching the end of its useful life (according to my refrigerator) we noticed the taste and smell got worse.  We noticed no difference in taste and smell when the Water Sentinel started to go. Were sticking with the Water Sentinel for now.
