Twin Undersink Bacteria/Rain/Tank Water Filter System (GT1-46WMAF)

Features:

  • Filters to 0.1 Micron
  • Blocks Giardia and Crypto (which are commonly found in tank & non-municipal supplies)
  • Eliminates the need for UV Sanitation
  • No wastewater produced (unlike Reverse Osmosis Systems)
  • Inexpensive to replace

Ultra-fine filtration is here and changing the way we filter water. The ability to filter water right down to 0.1 microns, takes away the need for powered UV appliances for the disinfection of bacteria, parasites and viruses. This is of particular relevance in older homes where power points are not readily found under sinks, or in caravans and camper vans. 

This system was designed in an "outside-in” direction so the life of the filter is enormously extended, but like all filtration the dirtier the water, the faster the cartridge will expire.

Disclaimer: Do not use this system to filter microbiologically unsafe water or water of unknown quality without adequate disinfection. We recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser to ensure full protection against microbiological contamination in your pipework and filter system, and to help prevent biofouling within the filter. 

Stage 1: Caware 0.1 Micron 3-in-1 Sediment, Chemical & Bacteria Reduction Filter

This cartridge is ideal for tank water applications, filtering out sediment and silt, followed by chemical reduction down to 5 microns using a 100% Coconut Carbon Block to reduce chlorine, volatile organic chemicals, pesticides and hazardous chemicals, and finishing with a 0.1-micron filter to protect against bacteria, viruses and parasitic cysts like Giardia & Cryptosporidium. Enjoy the sweet, mild taste of water as it should be!

Stage 2: 5 Micron Silver Impregnated Coconut Carbon Filter

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 Full 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

 

Replacement Filters - Every 6-12 Months or as required:

 

IMPORTANT INFORMATION ABOUT WATER SANITATION

Disclaimer: Do not use or drink microbiologically unsafe water or water of unknown quality without adequate disinfection.

FSA’s Recommendation for Rain/Tank/Potable Bore Water*

If you use Rain/Tank Water and Potable Bore Water (*i.e bore water has been tested to the Australian Drinking Water Guidelines and deemed suitable for drinking purposes per the Guidelines’ aesthetic, health and safety recommendations), please see below our recommended filtration schedule to ensure safe drinking water:

  1. Tank Dose with HydroSil Ultra 7.5% for Protection Against Bacteria & Viruses
  2. Undersink <1 Micron Absolute Filter for Protection against Parasites & (Optional) Coconut Carbon for Improved Final Taste & Odour

Read on for a full explanation of why we recommend this as the minimum standard of filtration for treating Rain/Tank/Potable Bore Water for drinking.

 

For Protection Against Bacteria/Viruses

Bacteria (such as E.Coli) can colonize in the stagnant water and result in harmful illnesses when consumed.
For sanitation against common water-borne bacteria/viruses in rainwater and potable bore water*, we, therefore, recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser to ensure protection against microbiological contamination/biofouling in your pipework and/or filter system.

HydroSil is a food-grade silver-activated, 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.

For Protection Against Parasites/Protozoa

Ingesting waterborne parasites (Protozoan Cysts) such as Cryptosporidium and Giardia (which flourish in raw water sources such as rain water tanks and bores), are a common cause of gastroenteritis.

Whilst Chlorine can inactivate Giardia with a moderate dose and contact time, Chlorine has a negligible effect on Cryptosporidium unless dosed in excess of the acceptable Chlorine limit per the Australian Drinking Water Guidelines (Version 3.6, pp. 200).

For protection against these common cysts, we, therefore, recommend under sink filtration down to at least 1 Micron (Absolute) or smaller (i.e. with Reverse Osmosis or the Caware 0.1 Micron Absolute 3-in-1 Sediment, Chemical + Bacteria Reduction Filter).

Such fine filtration, used along with regular sanitation (i.e. with HydroSil Ultra 7.5%) is a cost-effective and safe drinking water solution for rain water and potable bore water*, and is perfect for casual disinfection requirements such as when travelling in a caravan.

 

Why UV Disinfection is NOT Recommended for Caravans/Casual Use

You may have read that Ultraviolet (UV) Disinfection is one of the safest and most effective methods for treating drinking water, as it has a minimal effect on drinking water’s composition and taste, whilst killing 99.9% of microbiological contaminants. It's true that UV is highly effective at inactivating the DNA cells of water-borne micro-organisms such as bacteria and viruses, and is excellent at killing chlorine-resistant parasites such as Giardia and Cryptosporidium.

However, as effective as they are, please note that UV systems are generally NOT recommended for caravanning and casual use, for the following reasons:

  • UV Systems require electrical input and typically need to be left on 24/7 to prevent degradation of the UV lamp (not ideal for infrequent use).
  • UV radiation also heats up the UV chamber and, in some cases, requires a constant flow of fresh water and a thermal release valve to release the hot water (which is not ideal on a small water tank).
  • UV Systems also contain fragile glass components (not ideal for travelling).
