Introducing the Multipure Solid Carbon Block Filter – where innovation meets reliability in water purification. At Multipure, we understand the limitations of standard granular activated carbon (GAC) filters, which is why we have developed our signature solid carbon block filter. By leveraging the strengths of GAC and enhancing its performance, our filter provides a powerful solution to ensure the purity and safety of your drinking water.

Crafted with a carefully formulated blend of activated carbon and other filtration materials, our densely-compacted block design ensures that water passes through with optimal surface contact, dramatically enhancing filtration efficiency. This results in a compact yet powerful filter capable of treating a wide array of harmful contaminants, far exceeding the capabilities of conventional filtered water pitchers and even bottled water – which can often be just repackaged tap water.

The Multipure filter works in real-time at the spout, eliminating the need for cumbersome reservoirs while delivering clean, fresh water on demand. We don’t expect you to just take our word for it. Our commitment to quality is substantiated by thorough testing and certification from NSF International, a globally recognized agency for product performance evaluation. Transparency is key; we invite you to review our certifications and witness our dedication to excellence firsthand.

For over fifty years, Multipure has been at the forefront of water purification technology. Whether addressing the presence of arsenic-V, prescription pharmaceuticals, or pathogenic bacteria and viruses, we've consistently innovated to provide you with effective solutions without introducing additional chemicals or power requirements into your water. With emerging concerns regarding per- and polyfluoroalkyl substances (PFAS) like PFOA and PFOS, our filters are designed to safeguard your water quality and peace of mind.

Carbon Block Technology

Multipure has dedicated over five decades to the pursuit of cleaner drinking water, protecting the water in people’s homes and improving the health of families. For over five decades, Multipure has developed, refined, and manufactured the most powerful, most capable, and most reliable solid carbon block water filters and drinking water systems.

Introducing our state-of-the-art Solid Carbon Block Water Filter, the ultimate solution for clean, safe drinking water. Designed for both residential and commercial applications, our advanced filtration system effectively addresses the critical concerns surrounding drinking water contamination.

With the increasing awareness of water quality issues stemming from agricultural runoff, hazardous waste, and deteriorating infrastructure, the demand for reliable water treatment solutions has never been more urgent. Certain drinking water treatment units utilizing solid carbon water filters have been tested and certified to reduce upwards of 85 or more contaminants. These contaminants include disinfectants such as chlorine or chloramine, heavy metals or metalloids such as lead or arsenic, disinfection byproducts such as chloroform or trihalomethanes, and microbiological organisms such as bacteria, viruses, and cysts.

Our water filter tackles a comprehensive range of harmful substances, including chlorine, chloramine, and various heavy metals like lead and arsenic. Additionally, it efficiently eliminates disinfection byproducts such as chloroform and trihalomethanes, alongside microbiological threats, including bacteria, viruses, and cysts.

Activated carbon has been an effective material in the treatment of drinking water contaminants in use throughout history, and it is known to be effective in the reduction of disinfection byproducts, volatile organic compounds (VOCs), heavy metals, and variety of many other potentially harmful contaminants. Solid carbon block water filter technology transforms activated carbon into an even more effective and efficient form, and was developed by Multipure in the early 1970s for the purpose of creating a more powerful and more comprehensive solution to the treatment of drinking water contaminants. Multipure’s carbon block filter technology combines multiple methods of contaminant reduction action – mechanical filtration, chemisorption (chemical-reaction adsorption), physisorption (physical adsorption), and catalysis (catalyst-driven chemical reaction) – into a single device to reduce a broad spectrum of harmful contaminants.
  
In a Multipure carbon block, the activated carbon materials are selected for high activity. Years of research, development, and manufacturing experience have helped Multipure develop specifications for carbon and other media that give its solid carbon block water filters distinct performance advantages over alternative treatments. Quality assurance procedures are carefully developed and maintained to assure that raw materials meet Multipure's high standards.

Technological Advantages

As evidenced by independent laboratory testing and the certification of carbon block water filters, Multipure has been successful in developing the technology to produce filters that provide greater chemisorption, physisorption, catalysis, and mechanical filtration. Materials are heated and pressed into a densely compacted solid carbon block; compression enhances the kinetics of the filter and provides performance that cannot be achieved with granular activated carbon (GAC) – a cheaper and far less effective filtration media. Compacted carbon block water filters have a large surface area to better facilitate adsorption. With a solid carbon block, the water contact time is longer and provides for greater adsorption of many different chemicals, including pesticides, herbicides, and certain heavy metals. A close review of product listings confirms that Multipure drinking water systems are among the few that have been certified to reduce some of the more particularly difficult contaminants in water, including PCBs, PFOA/PFOS, and microcystin.
 
Multipure’s densely compacted carbon block allows for mechanical filtration of particles as small as 0.5 microns; at this pore size, contaminant reduction includes cysts such as giardia and cryptosporidium, asbestos, turbidity, and particulates. The incorporation of a pre-filter onto Multipure's solid carbon water filter design not only removes large particles and prevent premature clogging, but also better facilitates chemisorption. Because Multipure's carbon block water filters are exceptionally uniform in composition, they are not susceptible to channeling or bypass - drawbacks inherent to GAC filters.

Many newer, emerging contaminants – whose presence has been detected in water but whose effects on human consumption have not been explicitly demonstrated – have also been shown to be effectively treated by solid carbon block water filters. These contaminants include pest repellents (DEET), herbicides (metolachlor), antibiotics (trimethoprim), plastic components (BPA), artificial hormones (estrone), and over-the-counter drugs (ibuprofren or naproxen). Multipure products have been tested and certified for the treatment of these contaminants by NSF International under NSF Standard 401 (Emerging Compounds and Incidental Contaminants).

The addition of Multipure’s proprietary PureBlock filter media further enhances the power and ability of Multipure carbon block water filters, enabling for 6-log (99.9999%) removal of bacteria, 4-log (99.99%) removal of viruses, and 3-log (99.9%) removal of live cysts. Multipure’s Aqualuxe system features PureBlock-enhanced filters, and is NSF-certified as not just a water filtration device, but as a microbiological purifier (NSF Protocol P231).

Carbon Block Filter Capacity

Filter capacity varies depending on the density and size of the filter. The types and amounts of activated carbons used by Multipure determines the capacity of the water filters. Capacity ratings generally apply to the chemisorption and physisorption capabilities of the carbon and specialized filter media - carbon blocks with a high overall surface area allows for longer life and higher adsorption capacity. Capacity ratings for Multipure Drinking Water Systems range from 250 gallons to 1200 gallons, depending on the specific model.
 
Capacity claims are not applicable to contaminants reduced through mechanical filtration, due to the broad variations in the physical matter potentially present in the drinking water. Multipure solid carbon block water filters are engineered so that contaminants removed by mechanical filtration cause the flow rate to decrease and the filtration accessibility to narrow, thus offering protection to the consumer from giardia, cryptosporidium and other contaminants with a specific physical size.
