Xa kuthelekiswa ne-60-mesh filter, i-80-mesh filter ilungile. Inombolo yomnatha iqhele ukubonakaliswa ngokwenani lemingxuma kwi-intshi nganye emhlabeni, kwaye abanye baya kusebenzisa ubungakanani bomngxunya ngamnye womnatha. Kwicebo lokucoca, inani lomnatha linani lemingxuma kwikhusi kwi-intshi nganye yesikwere. Inani lemesh Ukuba liphezulu inani lemesh, kokukhona imingxunya engumnatha, kunye nokucocwa kokucocwa; Okukhona usezantsi umnatha womnatha, imingxuma embalwa yomnatha, kunye nokuhluzwa okurhabaxa.
Umnatha wesihluzi, obizwa ngokuba yi-mesh yokucoca, yenziwe ngemesh yentsimbi yeeminatha ezahlukeneyo. Yahlulahlulwe ngokubanzi ibe yimesh yokucoca isinyithi kunye ne-textile fiber filter mesh. Umsebenzi wayo kukucoca ukuhamba kwezinto ezityhidiweyo kunye nokwandisa ukuchasana nokuhamba kwezinto, ngaloo ndlela kufezekiswe ukuhluzwa. Inokususa ukungcola komatshini kunye nokuphucula umphumo wokuxuba okanye iplastiki. Isihluzi sineempawu ezifana nokuxhathisa ubushushu, ukuxhathisa kweasidi, ukuxhathisa kwealkali, kunye nokumelana nokunxiba. Isetyenziswa ikakhulu kwi-petroleum, kwishishini lemichiza, kwimveliso yoomatshini kunye namanye amashishini.
