仅来自于SKC---在计数、清洁、导电性、收集区和建造方面（石棉盒是5℃），滤匣可以满足NIOSH、OSHA和ASTM标准。

计数：OSHA方法ID-160要求，每100个区域允许有少于4个纤维，NISOH7400要求每100个区域有少于5个纤维能平均纤维本底。

清洁：OSHA ID-160和NIOSH7400要求在样品制备期间，清洁过滤器材料，以便样品具有均匀（非颗粒）本底。进行分析。这两种方法规定了相衬显微镜（PCM）分析 SKC BestChek过滤器材料经*清洁，以满足方法的规范，并适合进行PCM分析。

导电性：OSHA ID-160和NIOSH 7400要求使用导电性的滤料夹材料。导电性是包含在滤料材料中的炭黑数量的函数。ASTM标准测试方法和ASTM D257用于确定炭黑含量和测定导电性材料的方法。SKC Best Chek滤匣塑料包括超过18%的炭黑，用于使用ASTM方法测试的正确导电性。

收集区域：OSHA ID-160和NIOSH 7400中规定了385mm的相容的有效收集区域。

建造：OSHA和NIOSH建议使用无泄漏滤料夹，以便进行的空气采样
