This is the standard set of pre-filters for all of the following Undersink Reverse Osmosis systems:


These economical "HPF" PERFORMANCE sediment cartridges are constructed from polypropylene which is spun and melted simultaneously. This technique means there is no centre core to restrict filter performance. The "HPF" series of sediment filters are compatible with most liquids and are highly effective for sediment, rust, sand, silt, and algae removal. "HPF" performance sediment filters have no chemical residuals. They are extremely high performing, carry a heavy load of sediment before requiring replacement. We choose to use these sediment filters over all other types due to the high performance, high flow rate, high load capacity, and inability to grow bacterial slime. Also suitable for filtering room-temperature cooking oil. 


The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be sweeter 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.

This high quality 100% Coconut Carbon filter is the exact filter we use as our frontline 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.
