1.Low hygroscopicity 2.Chemically and biologically inert, with no organic binders 3.Offer higher retention efficiency of fine particles (<3µm in size) 4.Resist clogging for greater loading capacity than cellulose paper filters 5.Autoclavable and usable to 500°C (932°F) 6.Filters should be used flat: folding will break the glass fibers
