Whole House Water Filter System 10" x 4.5" + Ultraviolet Unit (1-7WMS 7-4K)

Twin System Complete With:
Stainless Steel Bracket & Screws
Opening spanner
5 micron NSF Poly Spun Sediment Cartridge
5 micron PURE Carbon Block Filter

This kit has been put together to meet the demands of many customers using tank water.

Tank water will always require filtration as it isn't treated like municipal water supplies.
The most cost-effective and total solution is to use UV Sterilisation, which will ensure 100% eradication of all Bacteria and Viruses from your house water supply.

The only alternative would be to use an under-sink filter for drinking water, which is effective at stopping cysts such as giardia but won't protect you from harmful bacteria or viruses such as E-Coli which can enter the water through frogs excrement. On top of this, all other taps i.e the shower, basins and other taps won't be treated so you can still be exposed to these viruses and bacteria via means other than ingestion.


Items Included In Kit

GT1-7WMS Twin Stainless System
GT2-16N Poly Spun Sediment Filter
GT4-13CTO Carbon Block Filter
GT7-4K Ultraviolet Sanitation System

The UV ballast is not waterproof and should be protected from water/moisture at all times.

5-micron Poly Spun Cartridge:

Poly Spun is the best type of filtration you can get. They do not accumulate bacteria as much as other materials, as well as being high flow and low-pressure drop. Effective in all applications. 5 micron is a reasonably fine filtration and would be suited on high quality bore water or town water or in front of RO's.

100% Virgin Polypropylene material - Compatible for Our Watermark Certified Systems

Purefer Polypropylene filters are made using a unique single nozzle manufacturing process, where a single nozzle blows melted polypropylene onto a spinning 5 micron filter core. As more Polypropylene is blown, the filter diameter gradually widens and the outer density of the filter decreases.

This unique manufacturing process gives Purefer filters a true Gradient Density that allows for a greater dirt holding capacity and higher filtration efficiency compared to standard melt blown filters made from multiple nozzle blowers.


5 micron PURE Carbon Block Cartridge:

This high quality 100% Coconut Carbon filter is the exact filter we use as our front line carbon filter. As a rule, it is difficult to find 100% coconut carbon filters. Most lower priced filters on the market are a blend of coconut carbon and coal-based carbon. The problem with coal-based carbon is that it has a shorter life and often results in a less palatable flavour. We use this 100% coconut carbon filter in all of our pre-assembled kits.

These are top of the range HIGH QUALITY coconut carbon block filters that are ideal for taste and odour issues, and perfect for total extraction of town water chemicals. TOP OF THE RANGE 100% coconut carbon, this particular filter is currently supplied throughout the European market as a premium drinking water filter. As the Exclusive importer to Australia, we are in a prime position to offer you this high-quality filter at rock bottom prices, direct from importer to the public.

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.

These filters are a terrific opportunity to purchase extremely high-quality filters at a VERY low price.

Carbon filtration is the best form of filtration for chemical extraction due to the longer and more thorough contact time the water has with the carbon, which in turn provides an extremely comprehensive method of chemical removal. We HIGHLY recommend this method of filtration for chemical taste and odour extraction.

Ultraviolet Sanitation System:

UV Water Sanitation is by far the most important filtration process when it comes to rainwater treatment. Rainwater harbours bacteria of all types but in some cases, much more harmful bacteria may be present in the tank. E-Coli is a common bacterium in tank water and is due mostly to frogs living in and around your tanks/catchment. Ultraviolet sanitation works by breaking down the cell wall of a micro-organism thus allowing oxidation to occur, which in turn prevents the bacteria from multiplying until it is finally eradicated. Ultraviolet filtration is a chemical-free solution to water sanitation that leaves no trace of by-products in the water.

Quarts Dome type Thimble

AS approved earthing and ballast.

The ultraviolet germicidal system has become an exceptionally popular water disinfection alternative. No micro-organism is known to be immune to UV. 
Heavy-duty UV lamps and quartz thimble using highest grade “hard glass” pure fused quartz to allow highest output Modern technology is incorporated to create the most natural purification. 
Ultraviolet lamps produce germicidal short wave radiation, which eradicates bacteria, viruses and other kinds of microbiological contamination present in all water supplies. 

These are recommended levels, for use as a guideline for pre-treatment requirements

Manganese: Tannins: Turbidity: Iron: Hardness: <120ppm


UV systems are not designed to be turned on and off. Doing this will shorten your lamp life. Lamps should be changed every year. The lamp may still be working, but after 1 year, the power will not be guaranteed to kill bacteria. The unit should be cleaned regularly. Hardness and other particles can build up on the quartz sleeve and on the inside of the UV chamber. 9000 hours (1 year) lamp life Working Pressure 100PSI


Why UV Disinfection is NOT Recommended for Travelling in 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).

Provided the system is stored out of the weather and stationary (i.e. in Stationary Home Caravan or Cabin), then UV is suitable.
