Likarolo tsaLisefa tsa HEM
Likarolo tsa li-filters tsa HME li entsoe ka hloko ho netefatsa ts'ebetso e nepahetseng.Ka tloaelo, li-filters tsena li na le ntlo, mecha ea litaba ea hygroscopic, le sekhahla sa baktheria / kokoana-hloko.Ntlo e etselitsoe ho boloka filthara ka mokhoa o sireletsehileng ka har'a mokulipotoloho ea phefumoloho.Mecha ea litaba ea Hygroscopic hangata e entsoe ka lisebelisoa tsa hydrophobic tse hapang hantle le ho boloka mongobo o tsoang.Ka nako e ts'oanang, sekhahla sa baktheria / kokoana-hloko se sebetsa e le mokoallo, ho thibela ho feta ha likokoana-hloko tse kotsi le likaroloana.
