Residential Whole house filter. Visit our store for water components. This is a high performance Big Blue 4 1/2 inch by 20 inch sediment filter (commonly referred to as 4 1/2 by 20 inch). These sediment filters are NSF Certified to Standard 42, FDA approved, 100% high purity polypropylene, surfactant free, binder free, adhesive free and they have high chemical resistance. These BB sediments are available in 1, 5, 10, 20 and 50 micron rated filters. The Big Blue carbon filters are manufactured with high purity Coconut Shell activated carbon with extruded activated carbon block construction. They do not release carbon fines and they are FDA compliant and they are NSF Standard 42 certified. These solid carbon block filters have combined the adsorption capability of carbon, with the ability of a solid block material to selectively strain out particles from the water that is being forced through the filter. These BB carbons are available in 1, 5 and 10 micron rated filters. Activated carbon has an electro-positive charge added which results in this type of carbon attracting more chemicals and impurities. As the water passes through the positively charged carbon, the contaminants with their negative ions, are attracted to the carbon granules and thus extracted from the water. The block of carbon strains out sediment, dirt, bacteria, microscopic worms, algae, asbestos and cryptosporidium. With just water pressure, this compacted solid carbon block is designed to filter sub micron size particles. This microstraining of the water will provide the cleanest and clearest drinking water available. Activated carbon bonds to thousands of known chemicals. As water is forced through this solid block of carbon, it is forced to slow its flow speed and thereby increase the contact time with the carbon. This slowing of the flow allows the carbon bonding to take place and remove chemical pollutants like toxins, THM’s, chlorine, pesticides, bad tastes, odors, etc. Solid block carbon filters are very uniform and do not channel or bypass as conventional granular activated carbon (GAC) filters are know to do. Because of the density of the solid block carbon filters, there is no room for bacteria to grow, so these filters do not become an incubator for bacteria as GAC filter are known to be. CTO carbon block filters preform well in both commercial and residential applications and they are the most widely used carbon filters on the market today.
