Have you ever felt the strange smell of ammonia vapors or the stinging sensation of HCl fumes? Bad news—not only is the smell disgusting, but the vapors can also harm the lining of your nose and damage your lungs and respiratory system.

Since then, it has been the gold standard in laboratories that work with chemical substances releasing toxic fumes, vapors, or particles that can harm the user.
Who needs the laboratory hood?
