About Samsung DA29-00003G
Point-of-use domestic water filters are designed to purify and condition the drinking water delivered to our homes through the mains supply. This has already been filtered at a water treatment plant, often using sand, but many of us choose to further cleanse our drinking water using a carbon filter to eliminate any bacteria or excessive mineral content which remains or may have contaminated it en-route to our taps.
Filter jugs designed to sit inside a fridge door are still popular, but for extra convenience many domestic fridges now feature a built-in water cooler which also has an integral filter component. Typically these carbon filters remove toxic chemicals like chlorine, lead and mercury and any other sediment including cysts.
The Samsung Da29 00003G is a filter cartridge specifically designed to fit the drinking water filter built into many Samsung fridges or fridge-freezers. Da29-00003G replaced Da29-00003B as the standard cartridge fitting in these appliances around August 2009. The reference number refers to a fitting rather than a specific product, and drinking water filters are made to this specification by many reputable manufacturers, many standardised to fit both older and newer fridge models.
All products that contact drinking water, including pipes and filters, should be certified by the Water Division of the NSF, a US-based international independent public health and environmental standards body, to confirm that they are not likely to cause contamination themselves. The NSF also tests for effectiveness in meeting claims like taste improvement and hardness and contaminant reduction. Look out for this globally respected data particularly when considering an unfamiliar brand.
