There are two filters, namely bacteriological filter and air filter.
a) bacteriological filters are typically used to sterilize materials that are not resistant to heating, such as sugar solution, serum, antibiotics, antitoxin, trace elements, enzymes, vitamins, hormones and or media containing materials etc.. Filtration technique using a filtering principle, which was filtered bacteria alone.
Among the types of bacteria that are commonly used filters are: Berkefeld (from fossil diatomae), Chamberland (of porcelain), Seitz (of asbestos) and seluosa. There are several types of membrane filters (nylon, polyethersulfone (PES), cellulose nitrate, cellulose acetate and mixed esters) with different pore sizes, for the purpose of sterilization is commonly used pore size of 0.2 mm.
b) high-efficiency air filter for filtering air containing particles (High Efficiency Particulate Air Filter or HEPA) air cleaner to allow supplies to be in a closed room with laminar air flow system (Laminar Air Flow)
