Absolute Pleated Filters
The Absolute Pleated Filters are Poly Propylene (PP) Pleated Filters inside of the Hard (PP) Plastic Shell, which provided rigidity during higher flow rates. The Absolute Pleated Filters have an absolute filtration rating, to ensure the highest level of filtration capacity and effectiveness.
An "Absolute" filtration rating means that the filter material has been specifically manufactured, and passed lab testing to ensure that 99.9% of the particles larger than the stated micron rating of the cartridge will be captured (trapped) on the surface or within the filter itself. In the case of our 0.1 to 0.2-micron Absolute Filters, this means that you will get the most effective removal of bacteria and organisms possible with 10" or 20" Big type Filter Cartridges.
Most sediment filter cartridge types such as Melted Sprays (PP), String Wound, Normal Pleated, and Antibacterial Melted Spray, have what is referred to as a nominal filter rating. Essentially what this means is that the micron rating of a filter is the approximate "average" size (diameter) of the pores on its surface and within the cartridge itself. It is generally accepted that filters with nominal filter ratings will retain (trap) around 85% of the particles equal or greater in size to the stated micron rating.
All our standard Absolute pleated filters are Double open-ended or DOE type cartridges, which means that they have two seals on either end of the filter cartridge, and are designed to fit into standard filter housings (both 10" and 20" Big). There are other types of absolute filter cartridges that have very different fitting designs, if you are looking for these types of absolute cartridges then we would recommend contacting our sales team, as these are typically special order filters.
The Absolute Pleated Filters are rated to 0.2 to 0.1 Microns, to put this in perspective, look at the sizes of the following objects:
- Eye of a needle ……………………………………….1230 micron
- Dot (.)…………………………………………………………615 micron
- Table salt……………………………………………………100 micron
- Human Hair (average diameter)………………….60 micron
- White Blood Cell…………………………………………..25 micron
- Red Blood Cell………………………………………………..8 micron
- Spider Web………………………………………………...2 - 3 micron
- Bacteria (harmful)……………………………………0.3 - 2 micron
With a nominal sediment filter, 60 – 98% of all the particles larger than the specified filter micron number are removed.
