Filter Information

Polypropylene Spun Sediment Filter - Compliant to NSF/ANSI 42

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.

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 flavor.

PURE FCT 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 and are ideal for taste and odour issues, and perfect for total extraction of town water chemicals. 

These perfect carbon block filters are 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, THM's while reducing chlorine and chemicals that contribute to taste and odour.

0.5 Micron Pure Coconut Carbon Filters

These high grade Coconut Carbon carbon blocks are infused with further additives and different composite materials for specific filtration requirements specifically targeting Chloramine removal. The specially prepared carbon block uses a unique material to break the bond between chlorine and ammonia that makes up Chloramines to absorb the Chloramine molecule from the water.
