Types of Filters
Bone Char | Carbon Block | KDF/GAC | Chloramine | Alumina
Bone Char:Our bone char is a 100% organic, Kosher certified filter media made up of 10% calcium carbonate, 10% carbon and 80% phosphate of calcium. It leaves behind the beneficial minerals we need, does not leach contaminates back into the water, does not affect water pH, and has no toxicity.
It can remove fluoride, radioactive isotopes, heavy metals and chlorine. It is much more effective than coconut filters because it is hundreds of times more porous and has calcium that attracts fluoride. Because fluoride is so hard to remove, we recommend multi stage systems. Two stage systems can remove up to 50%, three stage removes up to 75%, four stage systems remove up to 95%, and five stage systems can remove more than that. This is based on a level of 1.5ppm of fluoride.
Bone char is made out of charred animal bone, where cow bones are removed from cold storage, cleaned thoroughly, put into the rain and sun for at least 90 days and then completely dried. After that it is carbonized at 1472 degrees F under controlled conditions. What you're left with is a very effective, organic, Kosher filter media.
Bone char also removes chlorine, as well as cadmium, lead, iron, mercury, zinc, copper, manganese, nickel, aluminum, fertilizers, radio-nuclides, arsenic, radium, uranium, herbicides and pesticides. It is chosen by fish farms and can remove Nuvan, Malochite Green, Tributyl Tin Oxide, turbidity and odors.
A little about HA2 Supra L bone char - We don't use Supra L because it is ground extremely fine, clogs easier and does not last nearly as long as our bone char. Our bone char can filter about 5,000 gallons under normal use for a family of four, depending on fluoride levels. Typically, people only need to change filters once a year. We tested water before and after with a LaMott digital fluoride tester to prove its effectiveness. We highly recommend bone char for fluoride removal, as only steam distillation and reverse osmosis can match the capability.
Carbon Block: Carbon block filters are made from charred coconut shells, crushed to the consistency of a course flour before being pressed into a block. As water is pushed through, particles as small as 0.5 microns are filtered out. It polished the water, taking out pesticides, organic materials, bacteria, viruses, bad taste, cysts, bad odors, asbestos, cryptosporidium and giardia. It does not remove minerals, and is best used in combination with other media.
Granular Activated Carbon (GAC): GAC is a lot like carbon block but the pieces of carbon are larger. It's really good at getting rid of bad tastes and odors. It gets rid of many contaminates but isn't as good at removing particles in the sub-micron range. It's an ideal post filter used in combo with other filters, and does not remove minerals.
Kinetic Degradation Fluxion (KDF): KDF is proven to remove chlorine, iron, chloramines, bacteria, algae, fungus, most heavy metals, hydrogen sulfide and other contaminates. It's made of 50% pure copper and 50% pure zinc. When exposed to water it creates an electro-chemical reaction, converting free chlorine into simple chlorides.
Harmful components are rendered harmless. KDF removes 95% or more of chlorine before it gets to a carbon filter, making the carbon last 15 times longer. The electrolytic field forms hydroxyl radicals and peroxide and inhibits microorganisms. Because the zinc and copper ions tend to reattach to the media, KDF meets FDA and EPA standards. It does not remove minerals.
Chloramine Filter: If you choose the chloramine filter, you will get a catalytic AquaSorb high activity granular activated carbon filter that is made from coconut shell charcoal using steam activation. The catalytic activity makes this filter highly effective for removing hydrogen sulfide and chloramines from the water. The large micropore volume means it is ideal in particular for removing organic compounds with low molecular weights like chloroform and other THMs (trihalomethanes). Other features include optimized density, low turbidity and dust, maximum hardness, excellent capacity of absorption, rapid dechlorination and more.
Chloramines are used in municipal water systems to kill bacteria. No one wants bacteria in the water. However, more information is coming out about chloramines byproducts and the health hazards they could pose. The Canadian EPA labeled chloramine as toxic in the 1999 Environmental Protection Act. It is toxic to amphibians, fish, marine invertebrates and water-based reptiles.
Health issues may include blood and kidney problems, digestive problems and aggravated digestive disorders, a wide variety of skin problems, respiratory problems and other issues. In 2005 the California Conference of Local Health Officers reviewed past studies and recommended that the public exposed to chloramines be monitored for potential health effects of chloramine.
Alumina: We do not offer alumina because aluminum can be leached into the water if your pH isn't just right. It only lasts three to four months and can't remove THMs, chlorine or pesticides. It can also add a bitter taste to the water.
