NSF International’s Consumer Tips for Choosing a Drinking Water Filter to Reduce Contaminants
Recent studies and news reports have many Americans concerned about the possibility of contaminants in their drinking water. Fortunately, a wide variety of residential drinking water treatment and filtration devices are available. But how do consumers choose a filter that is sure to work?
NSF International, the global public health organization that led the development of national drinking water standards in the United States, independently tests and certifies drinking water treatment units and filters so consumers can be sure the products do what the manufacturers say they will do. This is especially important for filters and devices that claim to reduce potentially harmful contaminants like arsenic, lead, PFOA, PFOS, microcystin and radium.
NSF International’s drinking water filtration experts offer these tips to consumers who want to reduce potentially harmful contaminants in their water supply:
- Find out what contaminants may be in your water. Start by getting a copy of your water quality report (called a CCR or consumer confidence report) from your local water utility/authority. If you are unable to get your report or if you have a private well, you may want to consider having your water independently tested.
- Decide what contaminants you want to reduce. Once you know what is in your water, you can better find a treatment solution that is certified to address your water quality concerns. It’s important to understand that not all filters can reduce all contaminants.
- Consider your options. A number of water treatment solutions are available. They range from whole-house systems that treat all the water in your home to filters for specific areas such as the kitchen faucet and more portable solutions such as water pitchers. Some reduce only one contaminant while others reduce many.
- Choose an NSF certified product. Whatever water treatment or filtration option you choose, make sure it is independently tested and certified by NSF International. This certification means you can be confident and assured that the system will do what it says it will do.
