What type of air filter has minimal gas release when exposed to fire?

Class 1 air filters are designed to have minimal gas release when exposed to fire, making them a crucial component in reducing the risk of toxic fumes and smoke. These filters typically consist of non-combustible materials that do not ignite or release harmful gases at elevated temperatures. This characteristic is essential in maintaining air quality and safety in environments where fire conditions could occur, such as in commercial buildings and industrial settings.

In contrast, filters of other classes may contain materials that could release more harmful gases when subjected to fire. The significance of Class 1 filters lies in their ability to contribute to life safety by minimizing the potential for toxic exposure during fire incidents, enhancing overall fire protection strategies.
