Answer #1

Ans) Filtration is that passsage of a liquid or gas theough a screen like material with pores small enough to retain microorganisms, used to sterilize heat-sensitive materials, such as some culture media, enzymes, vaccines, and antibiotic solutions
-High-efficiency particulate air(HEPA) removes almost all miccroorganisms larger then .3um in diamyer for burn patients to lower numbers of airborne microbes.
