M'zaka zaposachedwapa, mpweya woipa wa VOC (Volatile Organic Compounds) wakhala chinthu chachikulu chomwe chimayambitsa kuipitsidwa kwa mpweya padziko lonse lapansi. Kupopera ufa pogwiritsa ntchito electrostatic powder ndi mtundu watsopano wa ukadaulo wochizira pamwamba wopanda kutulutsa VOC, kusunga mphamvu komanso kuteteza chilengedwe, ndipo pang'onopang'ono udzapikisana ndi ukadaulo wachikhalidwe wopaka utoto womwewo.
Mfundo yaikulu yopopera ufa wa electrostatic ndi yakuti ufawo umayikidwa ndi electrostatic charge ndipo umamatiridwa ku workpiece.
Poyerekeza ndi ukadaulo wachikhalidwe wopaka utoto, kupopera ufa kuli ndi ubwino uwiri: kusakhala ndi VOC yotulutsa komanso kusakhala ndi zinyalala zolimba. Utoto wopopera umatulutsa mpweya wambiri wa VOC, ndipo chachiwiri, ngati utoto sugwera pa ntchito ndikugwa pansi, umakhala zinyalala zolimba ndipo sungagwiritsidwenso ntchito. Kuchuluka kwa kugwiritsa ntchito kupopera ufa kungakhale 95% kapena kuposerapo. Nthawi yomweyo, magwiridwe antchito a kupopera ufa ndi abwino kwambiri, sikuti amangokwaniritsa zofunikira zonse za utoto wopopera, komanso ma index ena ndi abwino kuposa utoto wopopera. Chifukwa chake, mtsogolomu, kupopera ufa kudzakhala ndi malo oti tikwaniritse masomphenya a carbon neutral pamene tikufika pachimake.
