    What is a Carbon Block?

    Source: WQA

    Activated carbon block is a blend of fine activated carbon, water, and a suitable binder that is mixed and molded and hardened or extruded to a cartridge filter of any size and shape. Sometimes specialized media are added along with activated carbon to provide customized performances for specific contaminants.

    The binder is particularly designed and chosen to hold the carbon and other media in a fixed solid matrix, yet, not to plug up the pores of the activated carbon. Even though the binder does occlude a portion of the adsorption sites, the finer mesh size gives activated carbon block filters faster adsorption kinetics and generally two to four times greater adsorption capacity than equivalent volumes of loose granular activated carbon.

    Activated carbon block filters typically have a 0.5 to 10 micron filtration capability, making it also helpful for particulate filtration, removing taste and odor from chlorine, insoluble lead reduction, and demonstrating, in some cases, removal of Giardia and Cryptosporidium.

    What is a Granular Activated Carbon Filter (GAC)?


    A highly porous adsorbent material, produced by heating organic matter, such as coal, wood and coconut shell, in the absence of air, which is then crushed into granules. Activated carbon is positively charged and therefore able to remove negative ions from the water such as ozone, chlorine, fluorides and dissolved organic solutes by absorption onto the activated carbon. The activated carbon must be replaced periodically as it may become saturated and unable to absorb. Activated carbon is not effective in removing heavy metals.

    Activated carbon is often used as a filter in water treatment systems, where water is directed downwards through a stationary bed of activated carbon, leaving organic material to accumulate at the top of the bed. Activated carbon is similarly used to lower radon levels in water. Also available in powdered form.

  • Sediment Cartridges

    Sediment Cartridges

    Sediment cartridges remove dirt, sand and rust commonly found in water that travels through aging pipes and come in a variety of styles and micron sizes (pore size of the cartridge).

    Melt blown polypropylene cartridges are designed for the removal of dirt, rust and sediment from water. These filters have graded density layers, meaning the outer layers are more porous, catching larger particles while the inner layers are a finer micron, catching smaller particles.

    Pleated filters are designed to have an increased surface area and longer life. These cartridges are washable & reusable, and come in a range of sizes and micron (µ) ratings.

    String wound cartridges are designed for the removal of dirt, rust and sediment from water. These cartridges are rated for temperatures up to 125 °F. Polypropylene construction for excellent chemical resistance. No binders, additives, or lubricants to leach into the water.

    Inline Water Filters

    These filters are often used as a Reverse Osmosis (RO) inline post filter. They clip on to the membrane housing and filter the water after the bladder tank, acting as a polishing filter.

    Other applications include: ice makers, appliances, water coolers, coffee makers, and other low flow applications.

    What is a Thin Film Composite Membrane?

    Source: Wikipedia

    Thin film composite membranes (TFC or TFM) are semi permeable membranes manufactured principally for use in water purification or water desalination systems. They also have use in chemical applications such as batteries and fuel cells.

    Essentially, a TFC material is a molecular sieve constructed in the form of a film from two or more layered materials. Membranes used in reverse osmosis are typically made out of polyimide, chosen primarily for its permeability to water and relative impermeability to various dissolved impurities including salt ions and other small, unfilterable molecules.

    About Omnipure Filters


    In 1970, Omnipure Filter Company revolutionized the filtration industry by making the first small disposable, inline carbon filter. Their first filter, and every filter since, was designed to eliminate or reduce contaminants that cause unwanted taste, odor and discoloration in potable water. From this simple concept of "better tasting water", Omnipure Filter Company has grown and developed.

    In the beginning, Omnipure filters were used primarily on water coolers and ice makers. As the market has developed, our products have found their way into many more applications including commercial beverage equipment, under-the-sink and on the counter residential units, and drinking fountains. They are also widely used as components in commercial and residential purification systems such as reverse osmosis units. Today, you will find Omnipure filters utilized in virtually any situation where better tasting water is important.
