Pure LPD 20 Micron Low Pressure Carbon Block Whole House Water Filter Replacement Cartridge 10" x 4.5" Pure Coconut Carbon Block Filters are made from a combination of high-performance coconut shell carbon, unique binders and industry leading manufacturing processes to deliver trade quality carbon block filters. They deliver exceptionally low pressure drop while maintaining a high dirt holding capacity with excellent contaminant reduction capabilities. Pure Carbon Blocks are registered in compliance with NSF/ANSI 42, 53 and 61 for several things, including VOC’s, THM’s, Lead & Heavy Metal Reduction, Chloramine Reduction & Chlorine Taste & Odour reduction. This also includes meeting standards of purity & safety of the materials used. LPD Filters are utilised in cases that require the chemical reduction capacity of a carbon block, combined with the flow rate capacity and differential pressure drop of an impregnated Pleated Filter. The coarser micron rating of 20uM allows the filter cartridge to process a higher volume of water with as little resistance as possible. The success of this cartridge comes by way of the special combination of materials and high iodine number to provide chemical absorption you would expect from a standard CTO cartridge, while at the same time having almost 30% less media creating a thinner block wall, allowing water to flow at a higher rate with little resistance. Cartridge Guide Filter cartridge manufacturers rate cartridges in "microns". Microns are a size measurement of the pore size, so the smaller the number, the tighter the filter. One-micron Carbon Block Water Filter Cartridges are for drinking water only. In general, they are too tight to filter large amounts of water without slowing the flow to unacceptable levels. Filter cartridge manufacturers also use the words "absolute" and "nominal" to describe their products' micron ratings. Absolute means absolute. Nominal means "more or less." It is the micron size and the physical size of the cartridge which determines what that particular carbon block cartridge can be used for. For whole house filtration you can go as low as 5 micron. But for drinking water you would want to use from the 5 micron size down smaller. Carbon block cartridges are available in a variety of sizes and flow rates, and effectively provide good general-purpose drinking water filtration.
