Product review (4 stars): Works for DA29-00003G; however...
Our Samsung refrigerator came with the DA29-00003G filter but user manual says DA29-00003B filter since G is newer replacement model. However, the package for the advertised item lists it as the DA29-00003 or DA29-00003A filter replacement, possibly this manufacture did not update the list on the package although they update their web site, [...].

Plugging into our refrigerator, it does fit and works well.  It is not the same as the DA29-00003G:  the keying looks different (but still works) and the filter body is a bit longer than our OEM DA29-00003G filter.  We had to remove the top shelf to install this filter.

4 stars because it does work and is a replacement, and the price is awesome.  Not quite five stars because the description and title lists it as DA29-00003G when in fact it is not identical.  Perhaps more detail in the product description will prevent confusion upon receipt and installation.  Will buy again.
