Frequently Asked Questions
What is NSF Certification?NSF Certification is an assurance of quality and integrity. It states that:
- The system meets the contaminant reduction claims of the manufacturer.
- The system is not adding anything harmful to the water.
- The system is structurally sound.
- Advertising, literature, and labeling are not misleading.
- The materials and manufacturing process do not change.
Are Multipure Drinking Water Systems certified to reduce contaminants of health concern?Multipure's Drinking Water Systems have been tested and NSF certified under NSF/ANSI Standard 42 for reduction of aesthetic contaminants, and Standard 53 for reduction of contaminants of health concern. The replacement filters are also tested and NSF certified.
What contaminants are Multipure Drinking Water Systems NSF certified to reduce?Multipure Drinking Water Systems have been tested and certified by NSF for the reduction of many contaminants. More information can be found on our NSF Certification Page.
Are the Multipure Drinking Water Systems also certified or registered by the state of California and other states which have drinking water programs?Multipure Drinking Water Systems have been certified or registered in the states which require it, including California, Iowa and Wisconsin.
Is there a warranty/guarantee?Multipure demonstrates confidence in its Drinking Water Systems by providing a 90 day money-back guarantee. In addition, all Drinking Water System housings have a lifetime warranty, and all system accessories are warranted for 12 months.
Can the Multipure Drinking Water System be used during an emergency, or when the water is turned off?Yes, you can hand pump or siphon water through the Multipure unit during an emergency situation. Complete instructions are available from Multipure.
Can the Multipure Drinking Water System be connected to an automatic ice-maker?Yes. Multipure below counter Drinking Water Systems can be connected to any type of water dispenser or ice maker.
Does the system remove the natural, healthy trace minerals such as calcium, magnesium, or potassium?No, Multipure Drinking Water Systems leave in the healthful, naturally-occurring minerals.
Why did Multipure design the filter to take out contaminants like VOCs but not the natural minerals?Minerals are totally dissolved in solution and do not have an actual physical size; thus, the minerals pass through the filter unchanged. The materials used in Multipure Drinking Water are specially selected for their ability to react with the chemicals in the water but not with natural minerals. The ability to leave the natural, healthful minerals in while reducing harmful contaminants was a vital factor in the development of Multipure's Solid Carbon Block Filter. The medical community has always maintained that certain minerals are essential for a healthy body, and a study by the World Health Organization Workshop found that drinking water with high levels of beneficial, healthful minerals may reduce the risk of heart disease.1
