        Multi-Pure Drinking Water Systems have been certified or registered by the states of California, Iowa,         Wisconsin, Massachusetts and Colorado (all the states that regulate drinking water systems)

4.     Is there a warranty / guarantee?
        Multi-Pure Drinking Water System housings are warranted for 25 years on stainless steel units and 5         years on plastic unit and system accessories are warranted for 12 months.

5.     Can the Multi-Pure Drinking Water System be used during an emergency, or when the water is         turned off?
        Yes, you can hand pump (available for purchase) or siphon water through the Multi-Pure unit during an         emergency situation. Complete instructions are available from Multi-pure.    

6.     Can the Multi-Pure Drinking Water System be connected to an automatic ice-maker?
        Yes. The Multi-Pure Drinking Water System (Model MP750SB or MP1200EL) can be connected to any         type of water dispenser or ice-maker.

7.     Does the system remove the natural, healthy trace minerals such as calcium, magnesium and         potassium?
        No, Multi-Pure Drinking Water Systems leave in the healthy, natural occurring minerals.

8.     Why did Multi-Pure design the filter to take out contaminants like VOC and 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 Multi-Pure 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, healthy minerals in while reducing harmful contaminants was a vital factor in the development of Multi-Pure's solid carbon block filter. The medical community has always maintained that certain minerals were essential for a healthy body, and a recent study in Journal of the American Dietetic Assocaition found that drinking water with high levels of beneficial, healthful minerals may reduce the risk of heart disease.

9.     If the unit does not remove minerals, how does it take out lead?
        Multi-Pure was able to devise a solid carbon block filter whereby certain dissolved impurities, such as         Lead and chemicals, are adsorbed to the carbon surface by chemical reaction and adsorption.         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 can be analogized to a magnet that metal shavings (Lead, in the analogy) adhere to.

10.   If a filter can take out Chlorine, can it also take out Trihalomethanes (disinfection byproducts)?
        Multi-Pure 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 remove. But, chlorine that has interacted with organic material to form         Trihalomethanes (thus having a completely different molecular structure) is extremely difficult to         remove.

11.   Bacteria
        11.1     Does the Multi-Pure filter encourage bacteria growth in the filter?
                    Due to its adsurption technology, the bacteria is trapped and isolated by the filter. Since bacteria                     requires nutrients and oxygen to thrive and multiply, the isolation of bacteria cell will prevent the                     forming of clusters and colony.

        11.2     What are the bacteria and viruses removed by Multi-pure filter and to what level? Is there                      any certification to show that these bacteria are removed.
                    Please refer to Performance Data, ANSI/NSF Standard 53 Health effects and EPA contaminants                     List.

12.  Does boiling remove bacteria, viruses, cysts, chlorine, sediments, chemicals and other         contaminants from water?
        The traditional emergency prevention measure, boiling the water, is economically but environmentally         unsustainable.  No doubt boiling does kill viruses and bacteria, we do not drink the boiled water         immediately but wait for it to cool. As chlorine is dissipated by boiling, the cooled water is sceptical to         recontamination especially if it is transferred to another storage container.

        Boiling does not remove sediments or chemicals from water but may change the properties of any         chemicals that may be present in the water into something more dangerous thus making the water         ‘unstable’.

13.   Chemicals
        13.1    Are there any chemical addictive used in the Multi-Pure filter?
                   No chemical addictives are use in the manufacture of Multi-Pure filters.

        13.2    Is Multi-Pure filter able to remove O-Tolidine (Chlorine detector) and Clorox?
                   Multi-Pure Drinking Water systems have been tested and certified to reduce Chlorine and                    Trihalomethanes by NSF (Refer to Performance Data).

14.   Does the Multi-Pure filter remove salt from water?
        No. Multi-Pure filters are specially designed to reduce harmful chemicals but not natural minerals in
        the water.

15.   Isn’t bottled water safer than tap water?
        No, not neccessarily. There is no assurance that just because water comes out of a bottle is any
        cleaner or safer than water from a tap. In fact, an estimated 25% or more of bottled water is really just
        tap water in a bottle - sometimes further treated, sometimes not.

16.   Is Multi-Pure filter inspected for quality assurance?
        QC is done in U.S.A. ex-factory. Please evaluate QC standard of U.S.A. Both state and Federal Laws         and standard of requirements.

17.   What is the life-span of Multi-Pure filter and how do I know that the filter has reach its life-span?
        Filter life varies in direct proportion to the amount of water used and the level and type of impurities
        and contaminants in the water being treated. It is recommended that the filter be replaced when one
        of the following occurs:
              (a) the unit’s rated capacity is reached.
              (b) annually.
              (c) the flow rate diminishes (which occurs when the filter is clogged with particulate matter).
              (d) the filter is saturated with bad tastes and odors.

        Even if your filter is still white and flow rate is still high, according to EPA and state health department         guidlines, filters should always be replaced at least once a year, regardless of capacity.

18.   What are the parts that I need to replace and how often is the replacement required?
        Besides the filter, the other wear and tear parts are rubber sealants, neoprene hoses and faucets.
        Under normal use, we do not foresee any parts replacements for the next few years.

19.   Is the cartridge the same for the counter top and under counter Multi-Pure filters?
        Yes.

20.   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. The heat causes the carbon pores to open up. which could result in lead or chemicals being         released into the water. And, the carbon would not effectively reduce contaminants in the water. Hot         water is usually under 212 degrees, and that isn't hot enough to alter the raw materials, so there         wouldn't be any damage to the filter itself. If someone does run hot water through the filter, they should
        immediately run cold water through until the filter cools and then flush the filter for about 3 minutes.
        The filter then will again perform effectively. And, don't drink the hot water.

21.   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) without being used. If         the unit is to be left unused for more than 10 days, drain all the water from the system and remove the         filter. Upon your return reconnect the filter in the housing and continue use.
