Frequently Asked Questions

Multipure water filters are very highly regarded by consumers worldwide for their superior performance in doing what really counts: removing contaminants of aesthetic and health concern from drinking water, and producing the best tasting water. In evaluating a water filter purchase, many questions may come to mind. The following is a list of frequently asked questions that Multipure customers have asked.

Categories of Frequently Asked Questions:

Product Superiority

1. Why should I choose a Multipure water filter?

Multipure Drinking Water Systems are among the most effective, economical, convenient and reliable home water filters available today. Multipure water filters are certified by NSF International (NSF®) to reduce a wide range of contaminants of health concern, as well as aesthetically improve the water. Multipure filters reduce MTBE, chlorination by-products, PCBs, chloramine, pesticides, herbicides, heavy metals like lead and mercury, and many other contaminants.

Also:

  • Beneficial minerals remain in the water.
  • Nothing harmful is added to the water.
  • A variety of systems are available to suit any budget.
  • Healthier, cleaner water is conveniently available right at your kitchen sink.
  • Below Counter systems can be attached to a refrigerator or instant hot dispenser.
  • Countertop systems are portable and easy to move.
  • Multipure water costs about 9 cents per gallon.
  • There is a Lifetime Warranty on the stainless steel and plastic housings (provided that the filter be changed at least once a year), a 1-Year Warranty on the accessories, and a 90-Day Money-Back Guarantee!
  • 2. What makes a Multipure filter so effective?

    Nationally recognized standards established for the drinking water treatment industry confirm that the most effective systems for the removal of both aesthetic and harmful contaminants are those that utilize solid carbon block filters.

    The Multipure densely compacted Solid Carbon Block filter has the ability to micro-strain every molecule of water through microscopic pores. The large surface area allows the water to be in contact with the carbon for a longer period of time, providing greater adsorption of the many different chemicals, pesticides, herbicides and certain heavy metals. Contaminants with a physical size are removed when water passes through the pre-filter, which helps keep the carbon block from clogging prematurely.

    The developer of the proprietary Solid Carbon Block filter technology, Multipure Corporation, has been a leading manufacturer in the industry since 1970 (the first year Earth Day was celebrated) and has earned a reputation for performance and quality.

    3. How is Multipure filtered water better than tap water?

    Municipalities are required by law to deliver water to your home or business that is considered “safe” by the EPA. That is to say, the municipalities focus on reducing contaminants of health concern that have been specifically identified by the EPA. However, they do not necessarily remove all contaminants that may be present in the water. Also, they generally do not filter treated water to remove tastes and odors. They employ a variety of technologies that typically include some form of disinfection, but the chemicals employed for disinfection (e.g., chlorine or chloramines) leave tap water with a very noticeable taste and smell.

    Additionally, once the water leaves the treatment plant it must travel through miles and miles of pipes to reach homes and offices, including the water pipes inside your building. There are many opportunities for water to pick up contaminants along the way, and sometimes the disinfection chemicals actually promote the process of leaching contaminants into the water, such as lead.

    A Multipure water filter serves at the point-of-use to remove contaminants of aesthetic and health concern that may be present in tap water. A Multipure filter removes chemicals like chlorine as well as rust particles, dirt, small living organisms like cysts, asbestos, lead, and much, much more. The water you consume from a Multipure Drinking Water System is free of unwanted tastes and odors so that you may enjoy fresh, clean drinking water as it was meant to be. 

    4. If I can buy another brand of water filter for less money, why should I pay more for a Multipure Drinking Water System?

    All drinking water filters are not created equal. Quite simply, Multipure offers a superior product, and it costs more to design, test, certify and manufacture a higher performing product. The claim of superior performance is more than just “marketing speak”; Multipure product performance has been validated and documented through independent testing and certification by NSF International.

    There are many drinking water system choices available to you, and at first glance they may seem comparable. But they are not. Even among companies employing solid carbon block technology in their products, they do not match the proven performance of Multipure products. Superior performance equates to a better value for you over the life the product, and it gives you the peace of mind and satisfaction of knowing you are making a safe choice. Beyond just the initial purchase price of the water filter, be sure to calculate the 5-year cost of ownership of each alternative (i.e., add the cost of all the replacement filters you will purchase for 5 years to the initial product acquisition cost). Multipure filters are rated for 600~1,200 gallons before replacement, depending upon which Multipure model you select.

    Performance Certification


    5. Which Multipure Drinking Water Systems have been certified to reduce contaminants of health concern?

    All Multipure Drinking Water Systems for point-of-use water filtration have been tested and certified by NSF International under NSF/ANSI Standard 53 (Health Effects).

        1. This includes Multipure models Aquaperform, Aquaversa, AquaRo, Aquadome, and Aqualuxe, as well as the corresponding Multipure replacement filter cartridges.

     

    6. Why is NSF certification important?

    NSF International is an internationally recognized, not-for-profit, third-party testing organization that tests and certifies products to ensure they meet strict public health standards. Certified water filtration products are tested to verify that they meet certain standards for health and aesthetics. The end result for the customer is full confidence in the product’s performance based upon independent verification that the product will do precisely what the literature says it will do.

    Certification by NSF® assures the consumer that:

  • Claims of contaminant reduction are true.
  • The system does not add anything harmful to the water.
  • The system is structurally sound.
  • Advertising, literature and labeling are not misleading.
  • Materials and manufacturing processes do not change.

  • To ensure that manufacturers continue to meet these requirements, NSF® conducts unannounced inspections of manufacturing facilities at least once a year. Multipure Drinking Water Systems are tested under Standard 42 for Aesthetic Effects (for reducing taste, odor, and color) and Standard 53 for Health Effects (for reducing contaminants that are considered established or potential health hazards). You may learn much more about the critical importance of NSF® Testing Standards by clicking here.

    9. Aside from passing NSF product testing and receiving performance certification, in which states have Multipure water filters been registered?

    Multipure International has registered its products with every state that maintains a water filter registration or certification requirement, including:

  • California Department of Public Health
  • Iowa Department of Public Health
  • 10. Does the Multipure water filter remove healthy trace minerals from water, such as calcium, magnesium, and potassium?

    Multipure water filters utilizing solid carbon block technology DO NOT remove healthy minerals from drinking water. However, if you actually want to remove minerals and other total dissolved solids from your water, the Multipure AquaRO Drinking Water System, which combines reverse osmosis technology with Multipure’s solid carbon block, will in fact remove the minerals.

    11. How does Multipure design water filters to take out contaminants like volatile organic chemicals (VOCs) but not remove the natural minerals at the same time?

    Natural minerals in drinking water have been completely dissolved and do not have an actual physical size, so healthy minerals may pass through a carbon block filter without restriction. However, the specialized materials employed in Multipure Drinking Water Systems are selected for their ability to react with the chemical contaminants in the water but not with natural minerals. The ability to leave the healthy minerals in while reducing harmful contaminants has been a critical factor in the development of Multipure's unique Solid Carbon Block filter. Members of the medical community maintain that certain minerals are essential for a healthy body, and clinical studies have found that drinking water with high levels of beneficial, healthful minerals may reduce the risk of heart disease.

    12. How does a Multipure water filter remove lead but not minerals?

    Multipure International invented a Solid Carbon Block filter within which specific dissolved contaminants, such as lead and volatile organic chemicals, are attracted to the carbon surface and retained by chemical reaction and adsorption. Adsorption (as opposed to absorption) is the assimilation of gas, vapor or dissolved matter by the surface of a solid or liquid. The Solid Carbon Block filter at the heart of a Multipure Drinking Water System can be compared to a magnet that attracts and retains metal shavings; however, in this instance the filter attracts lead and other contaminants. The incredible amount of surface area in high quality activated carbon within the Multipure filter cartridge is an optimal environment in which to foster the adsorption process.

    13. Will any water filter that removes Chlorine also take out Trihalomethanes (disinfection by-products)?

    No, not all water filters that have been certified to reduce Chlorine can also remove Trihalomethanes. Chlorine is relatively easy to remove from water. But Chlorine that has interacted with organic material to form Trihalomethanes, and therefore has assumed a different molecular structure than that of Chlorine, is extremely difficult to remove. The only way to be confident that a water filter actually will remove Trihalomethanes is to check with NSF® or another other recognized certifying authority to verify the specific contaminants the product has been certified to remove. Multipure Drinking Water Systems are tested and certified by NSF® to reduce both Chlorine and Trihalomethanes.

    Product Use

    17. In the event of an emergency, such as an interruption to my home’s water supply, how can I use a Multipure water filter?

    In an emergency, water that is deemed safe from bacterial contamination may be manually pumped through a Multipure Drinking Water System with a hand pump. In fact, Multipure offers for sale a suitable hand pump that may be used in just such an emergency, or when the water is turned off. Please contact Water2Drink Customer Service (855-398-6726) for more information about the emergency hand pump or to add one to your system order. 

    18. How can I use a Multipure Drinking Water System with the automatic icemaker in my refrigerator?

        1. The Multipure Aquaversa, Aquaperform, and Aqualuxe below sink models may be installed with a T-connector on the filtered water output line to direct water to both a filtered water faucet and an icemaker. The same models also are available for inline-only applications, such as icemakers and refrigerators. The Multipure countertop system installations are not suitable for connecting to an icemaker.

     

    19. How often do the filters need to be changed?

    The life of any water filter will vary in direct proportion to the amount of water used and the type and level of impurities in the water being processed. It is recommended that the Multipure replacement filter cartridge be replaced when any of the following occurs: (a) the product’s rated capacity is reached; (b) the flow rate diminishes; (c) the filter becomes saturated with bad tastes and odors; or (d) annually. The filters cannot be back flushed or rinsed and used again. Even if your filter cartridge still appears fresh and the flow rate remains high, according to EPA and state health department guidelines, filter cartridges should always be replaced at least once a year, regardless of rated capacity. Additionally, Multipure Drinking Water System housings are sold with a Lifetime Warranty, but the filter cartridge must be replaced at least once each year to maintain the warranty.

    20. Will a Multipure Drinking Water System filter hot water? What will happen to the filter if I run hot water through it?

    The quick answer is “no.” Multipure products are designed to filter cold water only. The problem with running hot water through the filter is that higher temperatures very likely will trigger the release of contaminants that had been adsorbed by the filter. Heat also causes the carbon pores to open up, which could further result in trapped lead or chemicals being released into the drinking water. At higher temperatures, the carbon filter simply would not effectively reduce contaminants in the water. Hot tap water usually is well below the boiling point (212° F). That isn't hot enough to alter the raw materials within the Multipure filter, so there wouldn't be any damage to the filter itself if someone accidentally directed hot tap water through the filter. In the event that such a mistake occurs, immediately run cold water through the filter until it cools and then flush the filter for about 3 minutes. The filter then will again perform effectively. But please, don't drink the hot water!

    21. Should I disconnect the filter if it’s not used daily (e.g., vacation time)?

    You must not allow water to set in the Multipure Drinking Water System for extended periods of time (10 or more days) without being used. If the water filter is to be left unused for more than 10 days, you should drain all the water from the system and remove the filter cartridge. Upon your return, just reinstall the filter in the housing and resume use.

    Water Quality

    22. Where can I obtain a municipal water report for my city?

    All municipalities are required by the Safe Drinking Water Act to publish reports on the quality of water delivered through their systems. You may locate the water authority for your locale by visiting the public web sites identified below:

  • Environmental Working Group U.S. Tap Water Quality Database
  • U.S. EPA Safe Drinking Water Information System
  • 23. Where can I have the water in my home tested?

    If you want to know what contaminants are in your drinking water, check your annual water quality report from your water supplier or call the water supplier directly. If you want to have additional tests on your water, the U.S. EPA recommends that you use a laboratory certified by the state. Contact your State Certification Officer for drinking water laboratories, or follow the web link below to get a list of certified labs for your state:

  • U.S. EPA list of State Certification Officers for Drinking Water Laboratories
  • 24. What should I do if my home uses well water and not municipal water?

    If your water comes from your own well, the U.S. EPA advises that you test it annually, especially if you see signs of trouble like corroded pipes, strange odors or stained laundry. Your municipality, county or state health department may offer free or low-cost testing services; otherwise, you can use a laboratory certified in your state. For further information on well water quality, the EPA suggests consulting nonprofit groups like the American Ground Water Trust (www.agwt.org).
