Multipure Filtration Systems For Health and Great Tasting Drinking Water

Why Choose Multipure:

Multipure Filtration SystemsThe purchase of a high-end, high-quality Solid Block Activated Carbon filtration system is a lifetime investment in your health and the health of your family. 

Choose wisely!

Advantages of choosing a high-end  Multipure filtration system over other alternatives include:  

The Multipure MP750SB was the highest rated under-counter filter by Consumer Reports in February, 2012 and in 2013.  The Multipure 750 series was also awarded the Consumer Digest Best Buy over the Aquasana AQ-4000,  Brita AquaView System, Quixtar eSpring, Hydrotech AQ4V,  Kenmore 38460, American Plumberz  WRP-3500, and others.
You will purchase a product that you can trust to significantly reduce harmful contaminants in the water you  and your family will drink and use for cooking for many years.  You will purchase the best-value, most effective system available.
A cheap, $15 - $30 pitcher or  faucet-mount filter with limited effectiveness will actually cost as much or more than a high-end filtration system after a few years because of the relatively low treatment volume and high cost of replacement filters.  So you can eventually pay more for a less effective product as shown in the comparison charts,
A high-end water filtration system is much less expensive than bottled water, much less hassle, and in most cases the quality and taste of the filtered water are just as good or better than bottled water.  You can fill your own 25 oz. water bottle for less than $0.03.

Although SBAC filters do not treat all possible drinking water problems, Multipure SBAC filtration systems are an excellent solution for the majority of people who drink municipal water (and many who use water from private wells) and want to ensure that their drinking water is safe and good tasting. Review the list below of the contaminants that Multipure water filters are certified to reduce to see if they will work in your situation.

If your unfiltered water has a salty, metallic or bitter taste or smells like fish or sewage, read this to help understand your options.

Read this description of the Multipure SBAC filter technology.

 Benefits of Multipure SBAC filtration systems
The best certified contaminant reduction of the filtration systems reviewed by NSF International (see below, 
The strongest filter housing (heavy gauge stainless steel for most models).  This sets it apart from the majority of other filtration systems on the market that use plastic filter or thin metal housings which can crack and leak after a few years of service, or the plastic threads on the filter housings can strip over time as cartridges are replaced.
Among the longest warranties (a lifetime warranty for the housing and 1 year for faucet/hoses).
A company that has been a leader in the innovation and manufacture of high-quality SBAC filtration systems since 1970.  Multipure will "be there" when you need to replace your filter cartridge over the next 40+ years.  Multipure still provides cartridges for 40 year-old housings.

My family and I have used the Multipure under-counter MP750SB SBAC filtration system since 1996, and it has provided excellent service, great tasting water, and peace of mind since the day we installed it.

Company History:Top
Multipure pioneered the solid block, activated carbon filtration system in 1970. Since then they have continually refined their filters to significantly reduce the widest range of contaminants that a solid block activated carbon filter is capable of treating.
Over the years, Multipure has been the leader in developing filters that meet evolving treatment needs, contaminant concerns and certification standards. For example:
in 2002 Multipure was the first company to have its filters certified to significantly reduce the gasoline additive, MTBE, and the commonly used disinfectant, chloramine. 
In 2003 Multipure was the first company with a filter line (the 880 series) certified to significantly reduce arsenic V. 
In addition, out of all the hundreds of companies manufacturing filters over the years, Multipure SBAC filters have been the first that were certified to significantly reduce lead, asbestos, cysts, toxaphene, chlordane, and PCBs as those standards were developed.   Additional Company Information

Filter Certification:Top
Product Certification enables you, the consumer, to be confident that the advertising materials you read are accurate and that the certified product you purchase will perform as advertised.  NSF International, is an independent organization that has provided certification for a variety of products for many years.
Online NSF International Certifications Directory - Enter "multi" (without the quotes) into the box requesting the manufacturer name then click the 'Search by Manufacturer' button to view the Multipure listings for both Standard 042 (Aesthetic Effects ) and Standard 053 (Health Effects). Scroll down a bit until you see CB6 listed under "Replacement Element".  NSF provides a description of the contaminants reduced by the different Filtration Standards.

As you compare NSF certification contaminant reduction lists for different filtration systems, be aware of a practice I call 'padding the contaminant list' where a company pays to separately certify and list individual Volatile Organic Compounds (VOCs).  If a product is certified for VOC reduction, it is redundant and unnecessary to certify the compounds separately - except to look impressive.

Contaminant Reduction:Top
The certified list of contaminants significantly reduced by filter cartridges included in Multipure's filtration systems (** at 200 percent of capacity - that's after filtering twice the rated volume of the filter **) is:

 For Standard 042 - Aesthetic contaminants
     - Chlorine Reduction, Class I
        (actual chlorine reduction 99%)
     - Particulate Reduction, Class I
        (actual particulate reduction down to 0.5 micron)
     - Chloramine Reduction
        (actual chloramine reduction greater than 97%)
     - Taste and Odor Reduction

For Standard 053 - Contaminants of health concern and measured percent reduction
     - Arsenic V Reduction 95.8 - 99.9% - for the Aquaperform 880 and Aqualuxe models
     - Asbestos Reduction >99.9%
     - Chlordane Reduction >99.5%
     - Cryptosporidium, Giardia, Entamoeba, Toxoplasma Cyst Reduction 99.95%
     - Lead Reduction >99.3%
     - Mercury Reduction >99% - (pH 8.5) >91.4 (pH 6.5)
     - MTBE Reduction 96.6%
     - PCB Reduction >99.9%
     - Radon Reduction >94.9% - for the Aquaversa 750/1200 models
     - Toxaphene Reduction >92.9%
     - Turbidity Reduction >99%
     - VOC Reduction (volatile organic chemical) Reduction, including disinfection byproducts.
You will see a long list of specific VOCs (individual percent reduction for the various VOCs can be found on the product certification sheet below, but most are 98-99% or more). Performance Data Sheets for the C6 and CBAD and CD11A3 filter cartridges provide additional detail of the NSF Certification.
For Standard 401 - Emerging Compounds/Incidental Contaminants - new standard in 2014
Emerging Contaminants/Incidental Compounds is an American national standard that verifies the ability of a water treatment device to reduce up to 15 of the emerging contaminants. This list includes some prescription/OTC drugs, new types of herbicides and pesticides and chemicals used as flame retardants and detergents that have been found at trace levels in drinking water.
Multipure Aquaversa and Aqualuxe filter models are certified to reduce all 15 emerging contaminants.
Multipure also manufactures the 880 filter series which was the first activated carbon filter that was certified under ANSI/NSF standard 53 for significant reduction of arsenic V. The contaminant reduction of the 880 series, with the exception of arsenic reduction, is identical to the CB6 filter cartridge described above.  Water treatment chemicals or processes such as chlorine (where there is a free chlorine residual), potassium permanganate, and ozone will change arsenic III to arsenic V.
     - Arsenic (pentavalent As (V); As (+5); arsenate) reduction >99.9% (pH 6.5)
     - Arsenic (pentavalent As (V); As (+5); arsenate) reduction >95.8% (pH 8.5)
       NSF Press Release
The beneficial minerals, Calcium, Potassium, and Magnesium are not removed.   This is normally not important from a nutritional perspective, but these minerals contribute to the good, fresh "taste" of water that many people enjoy.

Comparing Filters:Top  

Relative Filter Sizes

Click for a larger (or very large) image

To which filter will you trust your family's health?

Confused about which filter to buy?
Try to find and compare equivalent product rating sheets (that specify the certified percent reduction of the  contaminants of interest as described above) for other systems you might be interested in evaluating.  Be skeptical and cautious if you can't locate that information for a filtration system.

Two companies might claim reduction of a particular contaminant. The statements might be true, but one filter might reduce the contaminant level by 99% and the other might only reduce it by 75% or less - or be certified for 100 gallons instead of 1,200.
Another important filter characteristic to consider (and compare among different products) is the amount of the filter media (the activated carbon) contained in the filter cartridge, the way it is manufactured, and the resulting pore size.
A Multipure filter cartridge weighs 31 oz, contains 70.6 cubic inches of highly compressed (solid block) activated carbon, and has a pore size of 0.5 micron.
A common faucet mount SBAC filter cartridge, by comparison, weighs 4.5 oz., contains about 7.5 cubic inches of activated carbon, and has a pore size of 1.0 micron. The most popular granular activated carbon (GAC) pitcher cartridge weighs 4 oz, contains granules of filtration media that are about 0.2 mm to 1 mm in diameter, and has pore sizes of perhaps about 30 to 50 microns.  View the Size Comparison Chart
If you look at certification lists for filters from a number of manufacturers you will see examples of a marketing game" played by some companies I call "padding the contaminant list". The "game" is played by paying NSF to test for (and list) specific contaminants that are already covered by a company's certification for Volatile Organic Chemical (VOC) removal. A company can display a long list of contaminants and look very impressive until you realize that many of them are double-listed. You can take a look at an example where one company lists 28 individual contaminants, 19 of which are duplicated in the VOC list, while Multipure lists 11 contaminants, none of which are duplicated in the VOC list:
A high-end filtration system is designed to provide decades of trouble-free service, so the purchase of a high-end filtration system is a one-time expense that will provide many years of pure drinking water with minimal ongoing costs. Although a Multipure filtration system has a moderately high initial cost, the yearly ongoing operating costs for most people is only $70 (under $6 a month).  Consequently, when you compare the cost of treating drinking water over a few years, the total costs of a high-end filtration system is frequently much lower than the cost of low-end filters that have a much lower initial cost, but higher cartridge replacement costs (for the amount of water treated). This link will enable you to compare the long-term cost of various types of water treatment options based on the amount of water you use (or plan to use) per week.
Filter effectiveness depends on contact time with, and proximity to, the filtration medium. A large SBAC filter will be much more effective in reducing contaminants than a small SBAC filter at the same flow rate (because water takes longer to move through a larger filter). Any SBAC filter forces all the water into close contact with the activated carbon (because of the small, uniform pore size) and will be much more effective than an equivalent size GAC filter.

*   Approximate filter capacity.  Heavily contaminated water will saturate/plug the filter more quickly.
(Treatment claims for NSF certified products cannot exceed 50% of the actual tested capacity. If the system includes a capacity meter, the claim can be 80% of the tested capacity.)
+ Average weekly water use based on a cartridge replacement every year.  If your water use exceeds that amount, you would just order a cartridge more often.
% In-Line Filter - (no faucet or water dispenser) Perfect for ice makers, coffee machines, etc.  An optional cold-water hookup kit is available for in-line filters if needed.
# Listed retail prices are in U.S. dollars and do not include shipping or state and local sales taxes where applicable.  Retail prices may change before they are updated here - check the current price of systems by following the provided links.
@ Capacity Monitor: In most cases a capacity monitor is not needed.  The listing of filter life with and without a capacity monitor can be somewhat confusing.  A filter's certified capacity without a capacity monitor can be listed at 50% of the actual NSF tested volume - this allows for considerable uncertainty in calculating the amount of filtered water used.  With a capacity monitor there is less guessing, and filter capacity can be listed at 80% of the actual tested volume. 
The standard Multipure C6 filter cartridge, for example, has been certified to treat 1,500 gallons of water.  Consequently, the filter life can be listed as 750 gallons without a capacity monitor the or 1,200 gallons with a capacity monitor (that's an average of 14 or 23 gallons per week respectively). 
Activated carbon filter cartridges, however, do not just fail after a specific amount of water has been treated.  They gradually lose their effectiveness over months, so normally there is no great urgency to change a filter cartridge at a specific moment in time.  Multipure (and most filter companies) also recommend that filter cartridges be changed at least every year so the user doesn't eventually forget the cartridge does need regular changing.  So, if you know the volume of water your filter cartridge has been certified to treat, and you have a rough idea of how much filtered water you are using, you can easily determine approximately how often you will need to change your filter without spending extra on a capacity monitor.
  Arsenic Reduction: If you are on municipal water it is unlikely you will need the arsenic reduction capability (and extra expense) of the 880 series, since arsenic levels are closely monitored and regulated.  If you have any concerns, however ,check your annual water quality report or have regular arsenic tests performed if you have a private well.
The current cost of replacement cartridges (on-line order) is $70 for the CB6, $125 for the CB11As, $150 for the CBLX, $45 for the CBMINI and $360 for the CB20 .  These costs do not include shipping and sales tax.
The capacity of the replacement filter cartridge for the stainless steel models is sufficient for many households for about a year (11 - 23 gallons per week average, depending on the model).
If you use more gallons of filtered water than the rated capacity in a year, you would simply change the replacement filter more frequently.  The under-counter units have a separate water tap that delivers about 0.75 gallon of filtered water per minute.
