Air filters are essential for safeguarding people from hazardous particles in the air. The Underwriters Laboratories (UL) classifies air filters into two categories: UL Class 1 and UL Class 2. Knowing the distinctions between these two classes of air filters is essential for selecting the right type of respiratory protection. UL Class 1 air filters are designed to provide flame resistance and emit only negligible amounts of smoke. On the other hand, UL Class 2 air filters are designed to burn moderately when exposed to flames or emit moderate amounts of smoke, or both. Particle filters are used to protect against dust, fumes, microorganisms, and viruses.
The lifespan of particulate filters depends on the environment and they become clogged over time, allowing less and less air to pass through. When it becomes difficult to breathe, it is a sign that the filter needs to be replaced. When selecting the right type of respiratory protection, it is important to consider the environment and the type of particles present in the air.
