North Safety 
CFR-1 particulate respirator
The CFR-1 particulate respirator is designed to provide workers in dusty construction and industrial environments added comfort and protection at better value than traditional disposable dust masks. The CFR-1 combines a reusable half mask with formed, easy-to-remove filters. The half mask comes in three sizes and is available with low-cost N95 disposable filters to fit a wide range of applications, including use in grinding, sweeping and cleanroom environments. A welding version of the North Safety CFR-1 is also available.
