Our Model MP750 Plus RO combines MultiPure’s renowned carbon block filter technology with the reverse osmosis technology, making it the most technologically advanced System in the world today. The MP750 Plus RO is the only device certified under NSF/ANSI Standards 42, 53, and 58 to reduce: Nitrates/Nitrate, Arsenic V, Chloramine, PCBs, Toxaphene, Chlordane, Lead, Mercury, etc. 


The MP750PlusRO Unit is easy to install and simple to operate. It uses no electricity and the impurities removed through the reverse osmosis process are flushed down the drain. The pre-filter component provides 5 micron filtration to remove large particulate matter and extend the life of the reverse osmosis membrane. The reverse osmosis component reduces the level of Total Dissolved Solids (TDS), rust, dirt scale, and organic tastes and odors. The processed water is conveniently stored in a 3 gallon pressurized tank which is small enough to fit neatly under your sink.

Multi-Pure's MP750PlusRO Unit includes pre-filter, RO membrane, and Multi-Pure’s Model MP750SB as a post-filter, giving you the highest quality water possible.

The MP750 Plus Reverse Osmosis System features FIVE Stages of filtration giving you performance that no other device can provide. By combining MultiPure’s superior carbon block filter technology with state-of-the-art reverse osmosis, you will receive the highest quality drinking water possible. Here’s how it works:

Stage 1: The Sediment Pre-Filter screens out particles down to 5 microns, improving the appearance of your water.Recommended filter change (Model No. CBC110): approximatelyevery 6 months.

Stage 2 & Stage 3: Carbon Block Pre-Filters -- next, water passes through two 5 micron Carbon Block Pre-Filters that ensure that chlorine and other materials that cause your water to taste and smell bad are reduced. Recommended filter change (Model No. CBC112): approximately every 6 months.

Stage 4: The RO Membrane is a high-production, 50 gpd, thin film composite semipermeable membrane that separates unwanted inorganic impurities, such as nitrates, fluoride, etc. from your water. This hyperfiltration membrane reduces salts, certain heavy metals, and other impurities, giving you great tasting water. Recommended membrane change (Model No. CB-ROM): approximately every 2 years.

Stage 5: The Carbon Block Post-Filter, the final stage of the water treatment process, provides the most efficient contaminant removal possible. Our densely compacted carbon block filter mechanically intercepts particles as small as 0.5 micron (sub micron) as well as electrokinectically adsorbs particles by attracting the negative ions of certain contaminants. In addition, the carbon block filter has a large surface area for chemical/physical adsorption to take place, reducing many different organic chemicals, pesticides, herbicides and certain heavy metals. Recommended filter change (Model No. CB6): approximately once a year.

The MP750 Plus Reverse Osmosis System delivers safe, deliciously clear drinking water that is convenient and affordable.   Without a doubt, will improve your tap water....

Depending on water chemistry, water temperature, and water pressure, the MP750 Plus RO System production and performance

will vary. Refer to Owner’s Manual for further maintenance requirements and warranty information.

Note: This Performance Data Sheet addresses the U.S. Environmental Protection Agency (USEPA) Primary and Secondary Drinking Water Regulations in effect at its time of publication, as they related to Multi-Pure's performance in conformance to the industry performance criteria. These regulations are continually being updated at the Federal level. Accordingly, this list of MCLs will be reviewed and amended when appropriate. Please see sales brochure for list of product certifications.

Replacement Filters and Parts

Filter life will vary in proportion to the amount of water used and the level of impurities in the water being processed.

Replacement filters, membrane, and parts can be purchased directly from Multi-Pure Corporation. Replacement filter model numbers are shown below. The approximate retail price of replacement filters is also shown below. Prices exclude sales tax and shipping and handling fees (*prices subject to change without notice).

To dispose of the used filter or membrane, remove it from the housing and place the old filter or membrane in your normal refuse.

Facts About Arsenic (in compliance with NSF Standard 58)

Arsenic (abbreviated As) is a naturally occurring contaminant found in many ground waters.  Arsenic in water has no color, taste or odor. It must be measured by a lab test. Public water utilities must have their water tested for arsenic. You can get the results from your water utility. If you have your own well, you can have the water tested.

The local health department or the state environmental health agency can provide a list of certified labs. The cost is typically $15 to $30.

Information about arsenic in water can be found on the Internet at the US Environmental Protection Agency website: www.epa.gov/safewater/arsenic.html.

There are two forms of arsenic: pentavalent arsenic (also called As(V), As(+5), and arsenate)and trivalent arsenic (also called As(III), As(+3), and arsenite). In well water, arsenic may be pentavalent, trivalent, or a combination of both.

Special sampling procedures are needed for a labto determine what type and how much of each type of arsenic is in the water. Check with the labs in your area to see if they can provide this type of service.

Reverse Osmosis (RO) systems are very effective at removing pentavalent arsenic. However, RO systems do not remove trivalent arsenic from water very well. A free chlorine residual will rapidly convert trivalent arsenic to pentavalent arsenic.

Other water treatment chemicals such as ozone and potassium permanganate will also change trivalent arsenic to pentavalent arsenic. A combined chlorine residual (also called chloramine) may not convert all the trivalent arsenic. If you get your water from a public water utility, contact the utility to find out if free chlorine or combined chlorine is used in the water system.

The MP750 Plus RO is designed to remove only pentavalent arsenic. It will not convert trivalent arsenic to pentavalent arsenic.

This treatment system was tested in a laboratory to remove pentavalent arsenic. Under lab conditions, as defined in NSF/ANSI Standard 58, the system reduced 0.30 mg/L (ppm) pentavalent arsenic to 0.010 mg/L (ppm) (the USEPA standard for drinking water) or less. The performance of the system may be different at your installation. Have the treated water tested for arsenic to check if the system is working properly.

The RO component of the Multi-Pure MP750 Plus RO system must be replaced as indicated in the Owner's Manual to ensure the system will continue to remove arsenic and other contaminants. The component identification and locations where youcan purchase the component are listed in theinstallation/operation manual.

         Reverse Osmosis Water Filters – How Do They Work ?

Reverse Osmosis is actually a simple process. Reverse Osmosis is a process that forces, by the application of pressure, the water to pass through a semi-permeable membrance that rejects heavy metals, salts, and inorganics, including healthful, naturally occurring minerals. After passing through the RO membrane, the product water passes through a holding tank. The process is slow and wastes 3-4 gallons for every one gallon of drinking water produced. Although the Reverse Osmosis membrane is somewhat limited as to contaminants reduced, it will reduce to a high degree the following: Arsenic V, Barium, Cadmium, Copper, Fluoride, Hexavalent Chromium, Nitrate/Nitrite, Particulate Matter, Perchlorate, Radium 226/228, Selenium and Trivalent Chromium. Reverse Osmosis does not effectively reduce VOC’s (toxic chemicals). RO alone is not sufficient if “healthy” drinking water is desired. Additional filtration is needed to produce water that can be considered to be “properly filtered”. Most manufacturers offer RO devices that include additional water filters that work in conjuction with the RO membrane to reduce additional contaminants such as different organic chemicals, additional toxic chemicals, pesticides, herbicides, and certain heavy metals. A system of this type will produce higher quality drinking water with more contaminants reduced. Always look for a system that reduces contaminants to at least 1 micron, 0.5 micron is even better. Keep in mind some contaminants, such as Bacterial Cysts, can be as small as 1 micron. The system should be installed as close as possible to the location (usually the kitchen sink) where the finished product will be delivered to the user.
