Pure Brand 100% Coconut Carbon Filters

  • High Quality, 100% Coconut Shell Carbon that Produces "Sweet" Tasting Water
  • Excellent Contaminant Reduction Capacity for Common Water Additives such as Chlorine, Trihalomethanes and Volatile Organic Compounds
  • Recommended 12 Month Lifespan if Used on Municipal Treated Water
  • Designed for Minimum Impact on Water Pressure

The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be the sweetest tasting water. The unique pore structure of this carbon is well suited for chemical absorption, including VOC's, while reducing chlorine and chemicals that contribute to taste and odour. Coconut Carbon provides a much higher volume of micropores than coal, wood, or lignite-based carbon. Thus, resulting in a more effective removal of trihalomethanes (THMs) from municipal water supplies. The larger surface area provides a more effective method of filtering common contaminants such as chlorine and chloramines. The unique raw material of the coconut shell and the carbon manufacturing process ensures exceptional hardness and low ash content.

Pure Brand's 100% Coconut Carbon Block Filters are made from a combination of high-performance coconut shell carbon, unique binders, and industry-leading manufacturing processes to deliver supreme-quality filtration. Expertly designed and manufactured, these filters deliver exceptionally low-pressure drop, resistance to sediment build-up, and excellent contaminant-reduction capabilities. Pure Carbon Blocks are registered in compliance with NSF/ANSI 42, 53, and 61 for several things, including VOCs, THMs, Lead & Heavy Metal Reduction, Chloramine Reduction & Chlorine Taste & Odour reduction. This also includes meeting incredibly high standards of purity and safety in the materials used.

GT4-19LPD - 20 Micron Low-Pressure Drop Coconut Carbon (For Effective Carbon Filtration Without Compromising Water Pressure)

    • LPD Carbon is perfect for those with low water pressure concerns. 
    • Use standalone to filter chlorine in low-pressure systems. 
    • Ideal Pre-Filter for use alongside finer micron-rated carbons for optimal filtration and help extend the life of your more specialised carbon blocks, whilst maintaining good pressure (i.e. 20 Micron Low Pressure Drop Carbon followed by a 0.5 Micron Chloramine Reduction Carbon OR 0.5 Micron Lead Reduction Carbon).

Low water pressure is often referred to as the ‘bane’ of water filtration. Most filtration systems require minimum working pressures exceeding 350kPa to ensure the system functions correctly and won't affect the flow of water pressure to the house. However, many off-grid systems rely on an external pump system and subsequently struggle with low water pressure. The 20uM Low-Pressure Drop Carbon is designed for these conditions. It has been specially manufactured to have a very low density to allow free-flowing water without compromising on chlorine removal. This is achieved by using a special blend of activated coconut carbon of a hydrophilic nature, which allows the carbon to have less contact time whilst removing the comparable levels of chlorine and other chemicals as other coconut carbon filters of this size. Carbon is also required in some tank** water applications to remove organic smells or tastes in the water. NOTE: This filter MUST be fitted in conjunction with a 5 Micron Pre-Filter if used for UV-treatment (i.e. for raw/rainwater**).

Filter 2: Your Choice of Coconut Carbon Block (See Below)

 

GT4-19CRC - 0.5 Micron Chloramine Reduction Composite Coconut Carbon (Reduces BOTH Chlorine and Chloramines For Maximum Chemical Reduction on Mains Water)

    • CRC (Chloramine Reduction Cartridge) filters out more chemicals/contaminants than standard carbon alone (which doesn't remove chloramine). 
    • Ideal for use after the 20 Micron Low Pressure Drop Carbon Cartridge (see above) for Maximum Chemical Reduction in mains-treated water.

Boasting a 0.5uM nominal rating, our 0.5 Micron Chloramine Reduction Carbon Block filter has a huge, highly reactive surface area of composite catalytic carbon designed to denature and neutralise chloramine with minimal contact time. As water passes through the Chloramine filter, Chloramine and other chemicals react with the carbon block surface, producing denatured compounds that are then re-adsorbed by the carbon - essentially neutralising the Chloramine and Chlorine molecules.

Why remove Chloramine? Chloramine is fast becoming the most important topic when it comes to mains water. Free chlorine has long been the choice for cheap and long-lasting municipal water disinfection, and it can be easily removed from water with minimal contact time. However, the addition of monochloramine gas (NH2CL - an inorganic molecule composed of chlorine-bonded ammonia) is becoming more and more common as a secondary disinfection agent that provides longer-lasting disinfection than chlorine alone. Aesthetically, monochloramine gives off a strong chemical/ammonia smell in the water. Whilst monochloramine is noted to produce lower (but still present) levels of chlorocarbons and carbon tetrachloride levels as compared to chlorine, unfortunately for the consumer, it can pose many health and aesthetic effects - from skin sensitivities & respiratory issues to heavy metal leaching. Especially when mixed with fluoride (another common municipal additive), chloramine can dissolve copper and lead, thus increasing pipe corrosion and the leaching of heavy metals. You may have seen this in action, as this is a common cause of blue/green staining in and around pipes, especially in areas with older infrastructure. Yes, Chloramine may kill pathogens in the water - but do you really want to be drinking it? Our answer is: probably not!
