The　method　to　control　diffusion　of　indoor　perfume　pollutants　in　building　was　studied.　Production　source　and　diffusion　characteristic　of　perfume　pollutants　were　discussed.　The　control　plan　was　proposed　that　pollution　sources　were　isolated　separately　and　then　pollutants　were　collected.　The　exhaust　system　was　designed.　The　optimal　flow　velocity　in　pipeline　was　obtained　to　be　5.6-6.0　m·s-1　based　on　numerical　simulation.　Test　results　proved　that　more　than　90%　of　perfume　pollutants　were　trapped　and　the　method　was　an　effective　way　to　control　the　diffusion　of　perfume　pollutants.
