FAQ
Choose a mask based on the hazard – dust, gas, vapor, or particles. Consider whether it’s a half mask, full-face mask, or disposable. Make sure the filter is certified to the correct class (e.g., P3, A2).
When working with sanding, painting, chemicals, insulation, or in dusty environments. Respirators are essential when particles or harmful substances may be inhaled.
Particle filters (P1–P3) protect against dust and fibers. Gas and vapor filters (A, B, E, K) protect against specific substances. Combination filters offer protection against multiple hazards at once.
Clean the mask body after use, store it dry and dust-free. Replace filters according to the manufacturer’s guidelines or when breathing resistance increases. Regularly check the seal.
Yes, if you use a respirator frequently or for extended periods. Reusable masks with replaceable filters offer better protection, more comfort, and lower cost over time.
