0.5 Micron Silver Impregnated (Bacteriostatic) 100% Coconut Carbon Block Water Filter | 20" x 4.5" (GT4-19BCCP5)
Filter Size: 20" x 4.5" Micron Rating : 0.5 Micron
Pure (brand) 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. Coconut Carbon is rated to be one of the best base materials used in today's market.
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 (THM's) from chlorinated municipal water supplies. The larger surface area of a compressed carbon block also provides a more effective method of filtering common contaminants such as chlorine and chloramines, whilst the unique raw material of the coconut shell and the carbon manufacturing process ensures exceptional hardness and low ash content.
Pure (brand) Coconut 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.
What is Silver Impregnated (Bacteriostatic) Carbon and how does it work?
Contrary to popular belief, carbon does not filter out bacteria. Whilst carbon effectively removes odours and taste issues from water, carbon ash is actually a source of nourishment for bacteria, making wet carbon filters a breeding ground for microbial contamination. This, unfortunately, causes biofouling of the filter cartridge which can lead to premature blockage, putrid tastes and odours and worse - illness as a result of ingesting the bacteria that has passed through the cartridge and into your drinking water! Using a rotten filter can make you seriously sick - so if in doubt - chuck it out!
Silver Impregnated Carbon, on the other hand, is bacteriostatic - meaning that it is proven to inhibit the growth of carbon-fed bacteria within the filter to prevent bio-fouling and prolong the life of a cartridge - even while it is not being used! Bacteriostatic Silver Impregnated Carbon filters are therefore great for use with Caravans and are ideal for periods of time where the filter may go unused. If you want to get the most out of your carbon filter, you can even go one step further and dry it out between uses!
So, how does Silver Impregnation inhibit the growth of bacteria in a carbon filter? When bacteria come into contact with silver, the silver ions puncture the bacteria's cell membrane and wreak havoc by binding to and denaturing the bacteria's DNA. The sulphydryl group already within the bacterial cell also reacts with the silver, producing a silver sulphur complex that immobilises the respiratory and reproductive activity of the bacterial cell. Interestingly, Silver Impregnation has an incredibly long-lasting effect, as the dead bacteria then leach the silver molecules back into their environment, effectively killing neighbouring live bacteria as they die.
Dead bacteria store the microscopic silver particles within their cells (see above image of dead bacteria with silver nanoparticles (white spots), making them deadly to live bacteria. (Source: "Antibacterial Activity of Silver-Killed Bacteria: The "Zombie" Effect" (2015), https://pubmed.ncbi.nlm.nih.gov/25906433/).
It's important to note that Silver Impregnated Carbon is BACTERIOSTATIC - meaning that it inhibits or prevents the increase or growth of bacterial levels WITHIN the filter only. Silver Impregnated Carbon Filters WILL NOT sanitise, disinfect or remove bacteria from water.
Disinfection For Protection Against Bacteria
For sanitation against common water-borne bacteria/viruses in rainwater and potable bore water (i.e. *bore water that has been tested to the Australian Drinking Water Guidelines and deemed suitable for drinking purposes per the Guidelines’ aesthetic, health and safety recommendations), we recommend dosing your water source with a product such as Hydrosil Ultra 7.5% Water Sanitiser. Dosing with a disinfectant will ensure residual protection against microbiological contamination/biofouling in your pipework and/or filter system. Alternatively, for a full-time point-of-use sanitation solution, consider Ultraviolet (UV) Water Sanitation.
HydroSil Ultra 7.5% Drinking Water Sanitiser
HydroSil is a food-grade silver and hydrogen-peroxide based water sanitiser, which acts to oxidise bacteria and viruses without leaving any dangerous residues behind. HydroSil sanitizes and protects your tanks and water storage devices, making rainwater and potable bore water* safe and suitable for human consumption. HydroSil is not a chlorine-based chemical like most sterilisers on the market today. It is non-toxic, and safe to use around your home and family.
Dosage Rate: HydroSil should be dosed at a rate of 200mL per 1000L of water. To scale down to tank size, you will require 20mL per 100L.
All orders placed before 12pm (QLD Time) will be dispatched same day by one of our preferred freight companies which include Australia Post, Fastway Couriers, Startrack Couriers & Border Express OR TNT For Large Orders.
Where possible, please provide your physical address or Work address so we are able to select the fastest and most efficient form of postage. In cases where a PO box, Parcel locker or any other Australia Post Service is provided, we will have to use Australia Post who have a wider range of parcel restrictions. If you have any doubt about your order or delivery address, please contact us prior to purchase.
Filter Systems Australia enforces strict dispatch protocols to avoid human error where possible. Orders are thoroughly checked and signed off, carefully packed to minimise chance of transit damage then recorded manually into a hard copy dispatch manifest. FSA now uses predominantly electronic labelling and freight services so all orders where applicable will have tracking numbers and daily manifest reports.
IMPORTANT NOTE:
All orders MUST be checked for damage within 48 hours of being signed for as delivered (based on tracking details). If damage is found you must contact us immediately providing photos of the damaged goods, and if possible, the damage done to the carton/box. This 48 hour period is a figure provided to us from our freight companies to approve transit warranty cases. If we are not notified of damaged goods within 48 hours, transit warranty will be void and FSA can no longer take responsibility for damaged goods. It is the responsibility of the buyer to have read the terms and conditions of Postage and Handling and understand the requirements for transit cover on all orders.
Approx. Transit Times
NSW: 2-6 Business Days QLD: 1-5 Business Days (Far NQ up to 10 Business Days) VIC: 2-6 Business Days SA: 4-10 Business Days WA: 6-15 Business Days TAS: 4-6 Business Days NT: 5-16 Business Days
Please note that the above estimates are taken directly from Australia Posts Business Customer Information. Where Possible, FSA will elect to use a Courier Service to minimise the delivery times from point of sale.
For orders in WA that fit in a 5Kg Satchel or less we usually will use Startrack Express in which case it will reach Perth overnight (and then subject to local WA Delivery times)
Please also note that while there is no express postage option available online, we are able to process the express post charge manually. If you require your item ASAP please contact us before purchase. If you have any questions pertaining to express delivery or additional cost, please contact us before purchase.
Authority To Leave
Please leave us a note on the purchase or message us direct after purchase to add a delivery instruction on your order.
