The Purezone system utilizes an infinite-telescoping weir which applies a powerful vortex to the surface of the water where most contaminants accumulate. This vortex draws water down into the filter assembly where it is screened through a one (1) Micron Purezone filter. Additional water is drawn from the bottom of the spa through the suction fittings where it is also screened through the filter before returning through the equipment and back to the spa. 100% of the spa water is filtered over and over again, assuring you of the cleanest spa water possible.
Pure-zone uses a disposable filter cartridge bringing an end to weekly filter maintenance. Filtering to 1 microns, the Pure-zone system provides up to 50 times the filtration of traditional filters. This eliminates the need for chemical clarifiers or defoamers. In addition, its silver ion impregnated core offers unsurpassed antiseptic, bactericidal, deodorizing, anti mold and anti algae properties. Coupled with O2's pioneering UV sanitising system, Purezone will assist in slashing chemical use and maintenance time.
High Density Depth filtration (Micron) is a process in which water is forced through microscopic caves and caverns in a tightly wound Polypropylene filter, rather than being sucked through a paper, pleated-type filter. This Polypropylene web forces the water particles to take a different path every time (see photo). High Density Depth filters use this same process and remove particles throughout the entire thickness of the filter.
The contaminants are taken out of the water two ways. By getting stuck in the Polypropylene web and by absorption into the material. Polypropylene removes these contaminants and traps them in its fibers, not letting them back into the water. The particles that would have formed a cake on the surface of a paper, pleated-type filter will now be spread throughout the entire High Density filter element instead. The path through the filter media is long and random. High Density Depth filters offer the best chance of contaminants to be captured in both the long term and the short term, and are more likely to capture semi-solids and particles of varying sizes. High Density Polypropylene Filters are not meant to be cleaned or reused. Simply toss out after a few months and replace with a new one to ensure brilliant High Definition clarity for your spa water, with much less chemical use!
