Pure1 Systems has announced the release of the Absolute1 – a unique combination of prefilter with the tightest absolute rated depth filter available to the point-of-use market.

The Absolute1 high-efficiency depth filter cartridge is constructed using an advanced microprocessor-controlled production process that permits the creation of multiple filtration zones within a single filter cartridge.

The four-zone design produces a gradient pore structure which effectively captures larger particles in the outer sections of the filter cartridge, while providing highly efficient and consistent removal of small particles in the inner sections, eliminating the need for an additional prefilter.

Manufactured from FDA-listed materials in polypropylene, the filters offer performance of greater than 99.9% of materials 0.5 µm or greater, as determined by the ASTM F-795 Test. The filter is free of adhesives, binders, resins and silicone.

“This unique product offers our customers the versatility of open prefiltration with a tight final filter in a single, disposable filter element," said Stephen Messinger, Director of Sales and Marketing for Pure1 Systems. "Replacing our existing PF-5 and PF-1 filters, the new filter will be less expensive than the two previous units, while offering greater removal of sediment and bacteria. The unit is available in a new Pure1-designed permanent housing and will be offered as the standard prefiltration in all SemperFresh filtration systems.” * About Pure1 Systems* Pure1 was started in 1988 to develop an answer to the problems with five-gallon bottles of water: lifting, spilling, storage, reservoir contamination and expense.
