Product review (1 stars): What is your health worth?
The WaterSentinel is only rated to NSF/ANSI Standards 42, which is only aesthetic effects or non-health-related contaminants (such as chlorine, taste and odor, and particulates).

The Samsung DA29-00020B cartridge is tested and certified by NSF International to meet or exceed NSF/ANSI Standards 42 & 53. while the WaterSentinel is only rated to NSF/ANSI Standards 42, which is only Aesthetic Effects. It does not remove any heavy metals at all which the Samsung does.

The commonly tested chemical reduction claims for products seeking certification to NSF/ANSI Standard 53 are: heavy metals (arsenic, cadmium, chromium, copper, lead, mercury and selenium), inorganics (fluoride and nitrate plus nitrite) and volatile organic chemicals (chloroform surrogate as well as individual organic chemicals).

Standard 42 covers aesthetic (taste and odor) claims, while Standard 53 addresses health-related claims, this is important to understand if you are trying to decide on using the watersentinel to replace your Samsung filter.

Personally, my health is worth more than the difference in price between these filters.

Removes 97.4% of Chlorine
98% of Particulates (Class I)
