3M Square Filters (PR) FFP3
Single 3M FFP3 particulate square filter cartridges.
FFP3 Filters protect against high dust levels as well as solid & liquid aerosols. FFP3 masks offer the best breathing protection from stone dust so are the perfect choice for workers who are cutting & polishing in busy workplaces with a high throughput as they protect against materials in concentrations up to 50x OEL or 20x APF. These filters are ideal for stone workers as their largest application is for those in the chemical and pharmaceutical industry for handling hazardous powders.
