    Three air sampling methods: sedimentation, impacting and filtration were compared in a food packaging materials producing factory. Sampling was performed four times during a year in three sampling places. The study showed that the results with all three methods used had similar trend. In general settle plates caught less microbes than other methods. The results for impacting and filtration methods were in many cases similar to each other. These methods were more sensitive than the method based on settle plates. A bigger sampling volume also used in filtration method did not increase the yield.
