新华网上海3月21日电 (记者周蕊)中消协联合包括上海市消保委在内的多省市消协组织21日发布的口罩产品比较试验结果显示，37款口罩样品中，仅有四成口罩过滤效果较好，而能够做到防霾效果既好佩戴又舒适的样品只有9款，占比不到四分之一。
比较试验结果显示，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。在过滤效果方面，37款口罩样品中，只有40%的口罩样品过滤效果较好，其中，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，15款一次性杯形口罩和一次性折叠口罩样品中有12款口罩样品与面部的贴合性较好，一次性杯形口罩和一次性折叠口罩的泄漏性能指标明显好于一次性平板口罩和可换滤片式布口罩。
而在佩戴舒适度方面，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。
中国消费者协会提醒广大消费者，在选用口罩时：一是要到厂家官网或正规销售渠道购买，确保使用正品行货。不要购买“三无”产品或标识模糊不全的产品；二是在佩戴口罩时，要保持口罩清洁，当感觉口罩有异味或阻力增加有憋闷感时，应立即替换掉口罩；三是要依据所处不同环境选用不同类型的口罩；四是患有呼吸系统疾病或老人、儿童等体质较弱人群宜佩戴阻力小、头带式的口罩。
根据本次比较试验结果，中国消费者协会建议：一是国家有关部门要进一步规范口罩产品的生产和销售行为，抓紧修订、 善相关标准，促进企业技术创新，不断提高产品质量，为广大消费者提供品质优良的防护用品；二是各有关生产销售企业应从消费者实际使用的角度，严把质量标准关口，不做虚假、夸大宣传，诚实守信、依法经营，努力营造良好的消费环境；三是呼吁全社会一起行动起来，抓紧治理好空气污染，让人们呼吸洁净空气，最终抛弃口罩，共同保护消费者的健康安全。
这一比较试验的发起方包括中消协、上海市消保委、安徽省消协、重庆市消保委、宁波市消保委和哈尔滨市消协。
