A depth filter, glass microfiber is made from 100% borosilicate glass, highly inert, and often used as a prefilter. It’s resistant to temperatures up to 500°C and a very wide range of solvents. When should I use it? DO USE: with most of common solvents, including aqueous and organic, strong acids and bases. The quality factor is the parameter to investigate the overall filtration performance of the filter, which considers both pressure and removal efficiency. The equation is defined as: QF = - l n ( 1 - E) Δ P where P (Pa) is the pressure drop and E is the removal efficiency. 3. Naturally degradable nanofiber filters.
HEPA filters are common today, however, HEPA filter technology has seen only minor advancement over the past several decades. The most common filtration media in use today, glass fiber filter paper, is fragile and prone to fire and water damage, as demonstrated by the Rocky Flats fire of 1957 (Ackland 1999). While better than the original
The first filter, or pre-filter, captures large particles like animal fur or lint. Next, the HEPA filter removes smaller airborne pathogens like mold spores and asbestos. Finally, most models have a carbon filter that tackles odors like smoke and mildew. Between the array of filters, up to 99.97% of pollutants are killed. True-HEPA Filters. A True HEPA filter is a fully certified HEPA filter that conforms 100% to the DOE standard for HEPA filtration outlined above. The word "true" is a claim presented by the DOE HEPA Standards and indicates that the "true" HEPA filter is the highest standard of air filtration available. When you come across a "true" HEPA filter
