Uhlelo lokupholisa lomoya wokuzalwa lwe-velirth luhlukaniswe ngomoya omncane wokucindezela, umoya omncane wokucindezela, ingcindezi elinganayo (noma ingcindezi emisha) yokuphefumula okuqondile) kanye nomoya omncane wemvelo. Ukuphefumula kwengcindezi yengcindezi kanye nengcindezelo yengcindezelo (noma i-Micro-Positingress (noma i-Micro-Positing) i-Ventilation system, kukhona nokuhlolisisa okungalungile kwendlela yesimanje yohlelo lwe-Filtration, leli phepha lemvelo lisetshenzisiwe, leli phepha liyethula kakhulu imodi yokucindezela engemihle yokunakekelwa komoya wokupholisa.
Endabeni yokuhlunga okungalungile kwengcindezelo engemihle, ngokuya ngezindlela ezahlukahlukene zokudla komoya, kepha futhi ihlukaniswe ngemodi yophahla, futhi uphahla olupholile lube yimodi yomoya, nophahla olulodwa kanye nomoya omude wemodi ehlanganyelwe yemodi ehlanganyelwe yekhethini. Ukushisa okuphezulu kwehlobo okungaphandle kwesifunda esibandayo saseNyakatho eChina akusikho ngaphezu kwama-30 degree, kungamukela uphahla emoyeni noma ku-Curtain epholile ophahleni lwemodi yomoya; Enye indawo ephezulu yokushisa ephezulu yehlobo kufanele yamukele inhlanganisela yophahla nomoya we-cert.
