PPE filters are mainly divided into three categories: particle filters (P1, P2, P3), gas and vapour filters (classified by letters such as A, B, E, K) and combined filters (which protect against particles and gases simultaneously). Particle filters are ideal for environments with fine dust, smoke or aerosols. Gas and vapour filters should be chosen according to the type of harmful agent present, such as organic vapours or acid gases. Finally, combined filters offer complete protection in more demanding situations. Choosing the right type is essential to ensure maximum effectiveness. RAG Tailors offers a wide range of certified protective filters, adapted to the most varied professional needs.
