HIGH PERFORMANCE CLEANROOMS
widely-used 99.99 percent efficient filters are three times more effective at filtering out 0.3 micron particles than the 99.97 percent filters that were common in the mid 1990’s. Ultra-low penetration air (ULPA) filters are even more efficient than those of the mid 1990’s.
