Cov kiv cua ion produces tus nqi loj zoo thiab cuam tshuam nqi airflow uas ua rau cov nqi ntawm cov khoom tsis muaj nuj nqi. Thaum cov nplaim ntawm qhov khoom tsis muaj nqi, nws absorbs tus nqi zoo nyob hauv cov roj kwj deg. Thaum tus nplaim ntawm qhov khoom yog qhov zoo, nws absorbs tus nqi tsis zoo hauv cov roj kwj deg, kom lub zog hluav taws xob nyob ntawm qhov khoom ntawm qhov khoom yog neutralized. Ua tiav lub hom phiaj ntawm kev tshem tawm hluav taws xob zoo li qub.
