Frequently Asked Questions

  •   1.   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.


    From extensive product testing and material analyses to unannounced plant inspections, NSF undertakes a complete evaluation of every aspect of a product's development before it can earn certification. NSF Certification is not a one-time activity - NSF requires regular on-site inspections of manufacturing facilities, as well as periodic retesting of products against the most current national standards. For the consumer, this allows NSF certified products to be purchased and used with confidence.

  •   7.   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.

  •   8.   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.

  •   9. 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.

  •   10. 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.

  •   11. 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

  •   12. If the unit does not remove minerals, how does it take out lead?

    Multipure's Solid Carbon Block Filter allows certain dissolved impurities, such as lead and chemicals, to adsorb to the filter surface. Adsorption (as opposed to absorption) is defined as "the adhesion in a thin layer of molecules to the surface of solid bodies with which they are in contact" (Webster's Collegiate Dictionary). Thus, the solid carbon block is like a magnet that lead molecules adhere to.

  •   13. If a filter can take out Chlorine, can it also take out Trihalomethanes (disinfection by-products)?

    Multipure Drinking Water Systems have been tested and certified to reduce Chlorine and Trihalomethanes. However, not all filters certified to reduce Chlorine can reduce Trihalomethanes (although some disreputable companies would have you believe so!). Chlorine is a substance that is relatively easy to treat. But, chlorine that has interacted with organic material to form Trihalomethanes (thus having a completely different molecular structure) is difficult to remove. Consumers must check with NSF (or their state health department if their state certifies water filters) to see if a non-Multipure filter is certified for Trihalomethanes or VOC reduction.

  •   14. How often do the filters need to be changed?

    Filter life 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 filter be replaced as soon as one of the following occurs: (a) the unit's rated capacity is reached; (b) a year has passed since the filter was installed; (c) the flow rate diminishes (which occurs when the filter becomes clogged with particulate matter); or (d) the filter becomes saturated with bad tastes and odors. The filters cannot be back-flushed or rinsed-and-reused.

  •   15. Can hot water be run through the filter?

    The biggest problem with hot water is the sloughing off of chemicals/compounds which had been adsorbed to the filter surface. Heat causes the carbon pores to open up, reducing the filtering effectiveness, and resulting in lead or chemicals being released into the water. This performance degradation occurs even though hot water is usually below 212 degrees F, and therefore not hot enough to alter the raw materials or cause damage to the filter itself. If someone does run hot water through the filter, immediately run cold water through the filter for at least 3 minutes, to cool and flush its contents. Do not drink hot water passed through the filter.

  •   16. If I leave on vacation, do I have to disconnect my filter?

    Do not allow water to sit in the unit for extended periods of time (10 or more days). If the unit will sit, unused, for 10 or more days, drain all the water from the system and remove the filter. Upon your return, reconnect the filter for normal use.

  •   17. Do Multipure filters reduce fluoride?

    Yes and no. Multipure's AquaRO is NSF certified for the reduction of fluoride. Multipure's Aquaversa, Aquadome, Aquaperform and Aquasource are not certified for Fluoride reduction. There are many filters on the market which claim to be able to remove fluoride from water, however Multipure has been unable to replicate or verify the performance claims of those filters & filter media. Reverse Osmosis & Distillation remain the only bona fide treatment technologies for the long term treatment of Fluoride at the point-of-use. Fluoride can appear in water supplies due to both manmade & natural sources.

  •   19. FREE Trial Back Office (CASH PROGRAM)

    Those IDs on a free trial of the Back Office are eligible for this program but if they do not continue with the back office after the 60-days, they will be removed from the CASH program.

  •   20. PAR Qualification (CASH PROGRAM)

    If the ID is NOT PAR qualified when their "turn" comes around they are skipped and the sale will go to the next person on the list. They will have missed their turn and will not get an allocated sale until their turn comes around again. This is an incentive for builders to stay PAR qualified.

    If a builder is enrolled in the CASH program and cancels their back office access, they will be removed from the program. If they decide to get access back into the back office, they will go to the bottom of the list. They will not be reinstated where they were originally on the list when they first opted in up for the program.

    Please note: builders will not be able to call us to find out where they are at on the list. This is proprietary information and will not be given out to anyone.

    EXAMPLE: If there are 300 people in the CASH program. Person #5 is not PAR qualified this month. We give out 20 sales this month and they missed out. We start at position #21 next month and do 20 more sales next month, they have to wait until all CASH qualified people are paid until their turn comes around again in position # 5 (which is after person #4). This is why is it so important for everyone in the CASH program to stay PAR qualified and keep their back office account active.

  •   21. What happens with CANCELLED orders? (CASH PROGRAM)

    If the order gets cancelled, the money would be deducted from the Builder, but that customer will still stay assigned to that ID. This way if the customer does decide to order from us or wants to become a Builder, they will be assigned to the original ID from the CASH program. The Builder will go back into the normal rotation with the other builders.

  •   22. Upline % Clarification (CASH PROGRAM)

    CASH allocations are provided to the 1st-level in-turn Active Builder ONLY. The in-turn Builder’s upline does not receive commission from CASH allocations.

  •   23. When will the CASH enrollment option appear in the Back Office?

    12:01am June 1st Pacific time

  •   24. What will the CASH enrollment option look like?

    When a new builders signs up for the back office, they will get the enrollment option pop up window when they log into their account for the first time. An existing builder that already has access to the back office will get the enrollment option pop up window when they log into the back office for the first time after the June 1st start of the program registration. They will only get the popup once. They will have to either accept or decline this program. If they don't read and decline this program, they can opt-in for it on the update profile page in the back office. They will be placed on the list according to when they opt-in for this program. They will not get another reminder when they access their back office

  •   25. Is there somewhere in the Back Office that the ID can look to "see and verify" that they are now enrolled in CASH?

    This information will be in back office on the profile page where the other opt-in information is. We will also have on the main page, if a builder is out of PAR, the date will show in Red so it will stand out to them.

  •   26. Will there be a designation on these orders in their back office to show that these are CASH sales?

    On the order it will show CASH program so we will all know how this order was processed. We may create a different order type (CS) for these orders since they will commission differently and will not be eligible for achievement levels, bonuses, trips, or PAR but we are still working on the details on this.

  •   27. What happens to a CASH payment if the customer returns their purchase?

    When a customer purchases a product directly from Multipure without a selling Builder, the Company Allocated Sales Handler (CASH) program immediately allocates that sale to the current PAR-qualified Builder in the CASH roster. If that product is returned, that transaction's CASH allocations are deducted from the receiving Builder, although that customer will remain linked to the CASH-allocated Builder for any subsequent purchases. The Builder's position in the CASH roster is not affected, and they will be allocated a CASH sale only when their position in the CASH roster next occurs.

    EXAMPLE: A customer purchases an Aquaversa directly through the Multipure online store, without a selling Builder. The CASH program allocates that sale to the current Builder position in the CASH roster, John Jones. John Jones receives his CASH commission for the Aquaversa purchase. Two weeks later, the customer returns their Aquaversa for a refund. John Jones loses his CASH commission, although that customer remains linked to John Jones for any future purchase commissions or prospective Builder Business. John Jones will not be eligible for another CASH commission until the CASH program proceeds through the rest of the CASH roster and comes back to John Jones' position in the CASH roster.

  •   28. Can a Builder receive a CASH payment if they qualify for PAR later in the month than the day of their CASH

    CASH allocations are assigned on the day of the customer purchase. Because of this, the CASH program checks the Builder's current-day PAR status at the time of allocation. If the Builder is not PAR-qualified on the day of a CASH allocation, then the Builder will receive neither the CASH payment nor that customer account, and the transaction will be allocated to the next person in the CASH roster. Even if the original Builder PAR-qualifies later in the month - making them PAR-eligible retroactively for the entire month - because the CASH program allocates on a day-by-day basis, that Builder will not receive a CASH payment until their position in the CASH roster next occurs.

    EXAMPLE: On July 5, a customer purchases an Aquaversa directly through the Multipure online store, without a selling Builder. The CASH program determines that Builder John Jones is the current position in the CASH roster, and checks his PAR status. As of July 5, John Jones is NOT PAR-qualified. Because of this, the CASH program skips over John Jones' position in the CASH roster and checks the next person, Builder Sally Smith. Sally Smith is PAR-qualified, so the CASH program allocates the Aquaversa commission to Sally Smith and her upline, and assigns that customer to Sally Smith for any future purchases or prospective Builder Business. John Jones sells an Aquaperform on July 14, and becomes PAR-qualified. Even though John Jones is now PAR-qualified for the entire month of July, he was not at the time of his CASH allocation, and therefore will not be eligible for a CASH allocation until his position in the CASH roster next occurs.

  •   29. Is there a minimum value for a CASH allocation to be paid out to a Builder?

    Yes. Because the minimum value at which Multipure can issue a commission check is $25, any CASH payments below $25 will instead be added into that Builder’s monthly commission check; this commission check with the CASH allocation will only be paid out once it reaches the minimum value of $25.
