What will Class 1 air filters do when clean in relation to fire risk?

Class 1 air filters are referred to as having low flammability. When these filters are clean, they are designed to not contribute to fire risk. This means they do not easily ignite or support combustion, which is critical in maintaining safety in environments where fire hazards are a concern.

In applications like commercial buildings or residential environments, using low-flammability materials is essential to minimize fire risks. Clean Class 1 air filters help ensure that the air circulating through HVAC systems remains safe and that any potential fire hazards are significantly reduced. Since the main purpose of these filters is to aid in fire safety by preventing the spread of smoke or flames, they play an important role in creating a safer indoor environment when maintained properly.
