Coconut Carbon Filters

  • High Quality, 100% Pure 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.

Our 100% 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 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.

LPD - 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. 
    • 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 high iodine 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**).

Example Filter Combo For Mains Water*:

Filter 1: 20 Micron Low Pressure Drop Carbon Block
Filter 2: Your Choice of Coconut Carbon Block (See Below)

IMPORTANT - A 5 Micron filter MUST accompany the 20 Micron Low Pressure Drop Carbon if intended for Pre-Ultraviolet Sterilization. Carbon as the sole means of filtration is insufficient for treating rain/bore water. Please refer to the note at the bottom of this page: **FILTERING TANK AND BORE WATER - IMPORTANT INFORMATION BEFORE YOU ORDER**.

CTO - 5 Micron Chlorine Taste & Odour Reduction Coconut Carbon (For Improved Chemical Reduction on Mains Water)

    • CTO Carbon is our standard recommendation for chlorine reduction, improved sweet taste and reduced odour - great value and quality!
    • Ideal for use after the 20 Micron Low Pressure Drop Carbon Cartridge (see above) for Superior Chlorine Reduction in mains-treated water.

Chlorine is generally the biggest concern for those on municipal water or those who use chlorine to disinfect their tanks, due to the offensive chemical smell and taste it produces, along with potential health effects resulting from topical exposure or consumption. Whilst Chlorine is effective at sanitising bacteria and viruses, Volatile Organic Compounds and Disinfection By-Products such as Trihalomethane (THM) and Chloroform can form when chlorine reacts with oxygen and other chemicals in solution. The Chlorine, Taste, and Odour cartridge will provide you with clean, great-tasting water free from nasty chemicals and remove or reduce any chemical smells in the water caused by free chlorine.

Example Filter Combo on Mains Water*:

Filter 1: 20 Micron Low Pressure Drop Carbon Block 
Filter 2: 5 Micron Coconut Carbon Block 

 

CRC - 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-absorbed 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, it may kill pathogens in the water - but do you really want to be drinking it? Our answer is: probably not!

Example Filter Combo on Mains Water*:

Filter 1: 20 Micron Low Pressure Drop Carbon
Filter 2: 0.5 Micron Chloramine Reduction Carbon

 

LRC - 0.5 Micron Lead Reduction Composite Coconut Carbon (For Chlorine Reduction & Heavy Metal Concerns in Rainwater, Old Infrastructure, Cities & Industrial Areas)

    • Dual Reduction of Chlorine and Heavy Metals.
    • Ideal for Filtering Tank/Bore Water** or Mains Water.
    • Recommended for use after the 20 Micron Low Pressure Drop Carbon Cartridge (see above) for improved chemical reduction in mains-treated water. 

Constant exposure to heavy metals combined with the different chemicals being used to treat our water supplies can have serious health effects, and can also cause severe plumbing problems within our homes. Rainwater (acidic pH) and chlorine/chloramine treated water (basic pH) both tend to be quite corrosive, and this can wreak havoc on the internal plumbing and fixtures within old municipalities and even the copper and brass fixtures in your home (which fittings may contain traces of lead)! Rainwater is also commonly contaminated with heavy metals - especially in cities and industrial areas. On this basis, it is also not uncommon to have elevated heavy metal levels in treated mains water supplies.

This cartridge is perfectly suited to reducing trace heavy metals that may be present in your water. The technologically-advanced Lead Reduction Cartridge ensures the reduction of heavy metals such as lead, arsenic, chrome, copper, along with Chlorine, Volatile Organic Compounds, and Trihalomethanes. 

Example Filter Combo on Mains Water*:

Filter 1: 20 Micron Low Pressure Drop Carbon 
Filter 2: 0.5 Micron Lead Reduction Carbon Block

Bore/Tank Water** Filter Combo Example*:

Filter 1: 5 Micron Pleated OR 5/20 Micron Poly Spun Sediment Filter (Not Included)
Filter 2: 20 Micron Low Pressure Drop Carbon 
Filter 3: 0.5 Micron Lead Reduction Carbon Block
Filter 4: Ultraviolet Treatment (Not Included)

BCC - 5 or 0.5 Micron Bacteriostatic (Silver Impregnated) Coconut Carbon Block (For Preventing Filter Biofouling in Raw/Tank/Bore** Water)

    • Ideal for Pre-Filtering tank** & Raw Water Prior to Ultraviolet Treatment.
    • Prevents Bacteria from Proliferating within the Cartridge.
    • Please refer to the note at the bottom of this page: **FILTERING TANK AND BORE WATER - IMPORTANT INFORMATION BEFORE YOU ORDER**.

Carbon doesn't filter out bacteria - and the scary thing is that this belief is a super common misconception! When filtering rainwater or other untreated water supplies, bacterial loading, biofouling, and cartridge contamination are big issues that can affect the performance and lifespan of your filters. Bacterial proliferation can prematurely block your filters which can cost you hundreds of dollars to replace cartridges more frequently than you should have to! Contamination is also a common cause of foul smells and tastes - and not to mention, it can make you seriously sick! Therefore, when it comes to filtering raw water, Bacteriostatic (Silver Impregnated) Coconut Carbon is the number one choice, as this media is specifically designed for use with tanks and bores* to prevent bacteria from breeding and colonising within the carbon and extending the life of your filter. 

How does Bacteriostatic (Silver Impregnated) Carbon work? When a cell of bacteria is absorbed into the carbon's structure, it comes into contact with silver ions. The sulphurhydryl group within the bacterial cell reacts with the silver, producing a silver sulphur complex.  The complex immobilises the respiratory activity of the bacterial cell by preventing the transfer of hydrogen and an oxidative reaction. The cell cannot reproduce and dies, reducing the risk of gastro illness by ingesting bacteria.

SMC - 0.5 Micron Surface Modification Coconut Carbon (For Reducing Water Discolouration/Tannin Reduction)

    • Ideal for Reducing Discolouration in Municipal, Tank** & Raw Water.
    • Also Filters out Chlorine.

Surface Modification Carbon uses a unique blend of highly reactive catalytic coconut carbon with the highest performance reduction technology. SMC filters are the best type of cartridges to reduce water discolouration, including rust and most tannins. Surface Modification Filters are commonly referred to as ‘Tannin Removal Filters’. Also filters Chlorine.

About Rain Water

Australia is the world’s driest inhabited continent, and an astonishing 10% of Aussies don’t have access to a mains water supply, so it’s no wonder why rainwater and bore storage tanks are so popular in rural areas to save water during drought and for household use all year round in cooking, cleaning, gardening, bathing and sometimes even drinking. However, whilst many people enjoy the sweet taste of rain and spring water, and some even swear by the ‘raw water’ trend (which proponents (sometimes falsely) believe has more minerals and fewer contaminants than regular chlorinated town water), we cannot stress enough that drinking untreated water is a very bad idea!

Scarily, in Australia, the general public perception is that rainwater is pure, clean, and safe to drink, but according to the Australian Environmental Health committee’s Guidance of the Use of Rainwater tanks, the fact is that the microbial quality of tank-collected rainwater is typically worse than regular urban tap water, and not to mention, the chemical quality of rainwater can be negatively impacted for those living near heavy industry or in areas with heavy traffic emissions. For example, rainwater samples in Port Pirie, South Australia, (which has one of the world’s largest lead smelters), have been found to contain levels of lead that exceed Australian Drinking Water Guidelines by up to ten times! Even bushfire can contaminate rainwater! And that’s not to mention the microbiologically sickening soup of bacteria, viruses parasites that inevitably make their way into your tank from disease-spreading insects such as mosquitoes, the excrement and decaying carcasses of frogs, snakes, rodents, and possums that commonly live in and around tanks, and the droppings from bats and birds flying overhead! Also consider that bacteria tend to proliferate in moist and warm environments, meaning that warmer weather, in particular, has the tendency to turn your tank into a putrified bacterial breeding ground. Thus, whilst rainwater may smell odourless, taste great, and look clean and clear to the naked eye, with the human senses alone, you simply cannot tell what potentially harmful microscopic contaminants could be lurking in your tank water (even after filtering the water with carbon) – and you certainly don’t want to be drinking it!

About Bore Water

Bore water will always require filtration, as whilst you would think it is “naturally purified” to some extent as the water seeps through the aquifer via various layers of bedrock, this water is highly susceptible to contamination by bacteria, viruses, parasites (see: Brain-Eating Parasites), sewerage (think human excrement, cleaning and bathing products), chemicals, fertilisers, pesticides, minerals, heavy metals (such as lead, zinc, chromium, copper, cadmium, arsenic and nickel), and sometimes even radioactive elements (such as uranium) from both natural sources and human activity. As with rainwater treatment, the most cost-effective solution is typically to use 5 Micron Carbon Filtration in combination with UV Sterilisation to ensure 99.9% eradication of all parasites, bacteria, viruses. However, this system is not always a "total fix", as bore water chemistry is incredibly complex, and sometimes may not even be treatable. Yet another common misconception we often encounter is that carbon can filter out anything and everything – but unfortunately, carbon doesn’t kill bacteria or remove minerals, salts and other such dissolved inorganic substances!

We STRONGLY recommend that you get your bore water tested to determine if there are any underlying issues in the water chemistry of your bore, before you make any purchases or try to filter it. If you have not had your water tested yet and would like to get this done, please contact us to have your bore water analysed.
