Near Absolute Filters

CT Tru-Test Filters meltblown cartridge filters are manufactured to high standards and our micron ratings exceed all Nominal ratings. We use a Computerized Porometric Analysis to measure the micron rating of our filters. These tests verify that our standard filters have much tighter pore distribution and thus filtering efficiency than other nominally-rated filters.

CT Tru-Test Filters also manufacturers a grade of filters that are near-absolute (NA Type). When tested side-by-side against very expensive competitive “Absolute” filters, our NA Type filters measure nearly the same in pore distribution, and for a lot less money.
