Our WaterMark certified filter systems are hand assembled here in Australia and are randomly batch tested to ensure top quality and workmanship for your water filtration products.

Inlet Tee - Compliant to NSF/ANSI 61

Gone are the days of struggling to get the right amount of thread tape onto your fittings (such as the feed water block and brass ball valve). Now, thanks to this handy combination fitting, it's simply a matter of interrupting your cold-water line with this tee and plugging in the 1/4" tubing to the filtration system.

The other benefit of this fitting is that by having the built-in isolation switch you can easily turn the water on and off for cartridge changes.

5 Micron Polypropylene Spun Sediment Filter

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 infront 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.

1 Micron 100% Coconut Carbon Filters

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. They are top of the range HIGH QUALITY coconut carbon block filters, ideal for taste and odour issues, and perfect for total extraction of town water chemicals. 

This particular filter is currently supplied throughout the European market as a premium drinking water filter, and 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 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.
