199元口罩效果比2元的还差 市场上仅四成可防霾

  东方网3月25日消息:据《劳动报》报道,记者昨了解到,根据连日来中消协联合上海市消保委等对37批次口罩产品抽检结果显示,从单价0.58元到199元的口罩产品,仅四成有防雾霾功效。一些口罩防护性能与价格不匹配,同类产品同等防护性能,但价格可能相差一倍以上。

  记者注意到,结果显示,37款口罩样品总体防护性能不太理想,不同样品间防护性能指标差异较大,一次性口罩样品一般好于可换滤片式布口罩样品。在口罩与面部贴合性方面,呼吸阻力小的样品(带有呼气阀的样品除外),可能存在过滤效率偏低或泄漏率偏高的情况。抽检比较试验发现,样品口罩标识混乱。样品规格型号标注各式各样,有标注口罩尺寸的,有生产企业自编型号的;有24款样品标注生产日期;24款样品标注了口罩的有效期,一般标称为三年或五年。其中有12款样品生产日期和有效期都没有找到标注。

  比较试验通过测试“过滤效率”来检验不同口罩对颗粒物的过滤效果。但结果显示,口罩的过滤颗粒物效果差别大,不少口罩的价格与过滤效果不符合。如售价29.8元的汤默臣口罩、售价27元的华绣科技口罩与售价24.9元哈雷口罩的过滤效果远不如多款10元以内的产品。而售价为199元一个的“totobobo”可换滤棉式 橡胶 口罩,其过滤功能与售价1元的“保为康”POWE鄄COM新国际防尘口罩的过滤效果相同,比售价1.9元的“爱丽思”一次性立体防尘三层防护pm2.5口罩的过滤功能还要差。

  此外,本次比较试验样品中,2款无中文标签样品都是通过互联网购买得到的。大型超市、商场、药店销售的口罩样品质量相对比较可靠。
