Understanding PFAS and How to Reduce Them in Your Drinking Water

Per- and polyfluoroalkyl substances (PFAS), including PFOS and PFOA, are persistent chemicals found in various water sources. These substances are known for their resistance to conventional water treatment methods and potential health risks.

Why PFAS are a Concern:

• Persistence: PFAS are often called "forever chemicals" because they do not break down easily in the environment.
• Health Impacts: Long-term exposure to certain PFAS has been linked to various health issues, including cancer.

Effective PFAS Filtration: Advanced filtration technologies can significantly reduce PFAS levels in drinking water.

• Coconut Carbon Block Filters: Carbon block filters are made by compressing activated carbon into a solid block, which forces water to pass through a dense matrix, ensuring more uniform contact. This design leads to longer contact time with the carbon, enhancing adsorption efficiency for contaminants like PFAS. Additionally, the fine pore structure allows for the physical filtration of particles, providing an extra layer of contaminant removal.

 

SMC - 0.5 Micron Activated Coconut Carbon Block - Superior Adsorption)

• • Ideal forAdsorbing unwanted chemicals from drinking water.
  • Also Filters out Chlorine.

Surface Modification Carbon uses a unique blend of highly reactive coconut carbon with the highest surface area for optimum adsorption of contaminanats.

 

FSA'S MAINS (CHLORINATED) WATER RECOMMENDATION + THINGS TO CONSIDER

• FILTER SIZE - The 20" x 4.5" size of system enables the maximum surface area and contact time for chemical reduction, and the best possible flow rate to prevent water pressure problems (which can occur by selecting too small a system). This system is designed to handle high flow, and on pressure-limited mains water (500kPa) you should not notice any significant reduction in pressure during regular water usage for an average household. However, if you suspect that you have lower than average water pressure and/or you are not sure whether this system will meet your requirements, please contact us to discuss before you finalise your purchase. Need a water pressure test kit? Click here. If you have an unusually large household, a property with multiple guest suites, or commercial requirements for filtration, it may be viable to run two or more 20" x 4.5" Systems in tandem. If this is the case, please contact us to discuss your requirements before you finalise your purchase.

 

• HOW TO USE A PRESSURE GAUGE?
  • You may also wish to opt for a set of pressure gauges (especially if you are running a Dual Carbon set-up) to help determine how clogged your filters are, and monitor the performance of your system. Simply mark the level of pressure on the gauge upon installation or when you install a new set of filters - reduced pressure over time indicates filter blockage. 

 

• INSTALLATION - Please note this system is WaterMark Certified to Australian Plumbing Standards (AS/NZS 3497), and will need to be installed by a licensed plumber. Simply order online with free shipping to your home, and once it arrives any local licensed plumber will be able to do the installation (the system also comes with instructions)! When calling around for quotes, be sure to ask about installing a "bypass" (see pictures below) so you can still get water into your home when the time comes for filter changes! Normally, a whole of house system will be installed wherever the mains water line tees into your property. As this system is UV resistant, it can be installed in direct sunlight or in the shade.
• FILTER CHANGES AND MAINTENANCE - Lastly, we recommended filter changes on an annual basis, and offer a 12-monthly filter reminder email service to help you remember! Simply email info@filtersystemsaustralia.com.au when you place your order, and ask us to set you up with a filter reminder! Filter changes are easy enough - simply turn off the water going into the system, press down on the pressure relief valves, unscrew the sumps, replace the filters, screw it back up and turn the water back on! You may notice the water feels a bit "slippery" at first after installing new filters, but don't worry - this is normal and will go away quickly once enough water has run through the new filters. Also, if the water looks cloudy at first, again - don't stress! This is dissolved oxygen and it will go away quickly once enough water has run through the new filters.

Sediment Filters

• 5 Micron is well suited for mains/town treated water and high-quality tank/bore** water.

Poly Spun (Polypropylene) Disposable Sediment Filters

• • High Flow & Low Pressure Drop
  • Cost-Effective & Disposable

Poly Spun filters produce a high flow and low pressure drop, and do not accumulate bacteria as much as other materials. They are highly cost-effective and disposable. All of our poly spun filters are made of 100% Virgin Polypropylene. Polyspun filters are manufactured to create a gradient density that allows for excellent sediment-holding capacity and filtration efficiency.

Polyspun Filter Options:

• • • 5 Micron Polyspun Sediment Filter Cartridge

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.

 

**FILTERING RAIN, TANK AND BORE WATER - IMPORTANT INFORMATION BEFORE YOU ORDER**

 

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.
