The　adsorption　behavior　of　CO2　and　volatile　organic　compounds　(VOCs)　on　a　non-woven　fabric　loaded　with　activated　carbon　was　investigated.　The　experimental　results　show　that　lower　air　velocity　is　helpful　to　the　adsorption　of　CO2.　The　effect　of　temperature　on　CO2　adsorption　is　small,　but　lower　relative　humidity　is　beneficial　to　the　adsorption　of　CO2.　The　adsorption　efficiency　of　VOCs　on　the　non-woven　fabric　is　independent　of　the　concentration　of　VOCs　at　windward　side　while　it　is　dependent　on　the　type　of　pollutant　sources.　And　lower　air　velocity　is　helpful　to　the　adsorption　of　VOCs.　Increasing　the　number　of　adsorption　layers　can　result　in　an　increase　in　the　absorption　efficiency　of　the　non-woven　fabric　for　both　CO2　and　VOCs　while　it　also　increases　the　resistance　of　the　cleaning　system.　The　absorption　efficiency　does　not　increase　anymore　when　the　number　of　the　layers　is　over　3　in　the　study.　Then　the　suitable　thickness　of　adsorption　layer　is　of　significance　for　high　absorption　efficiency　and　low　energy　cost.
