Respirator Cartridges for Solvents

Respirator Cartridges for Solvents

• Organic vapor” cartridges are the only type that capture solvent vapors.
• Cartridges for solvents will absorb only so much solvent until breakthrough occurs.
• Cartridges are not suitable for some solvents since they are not trapped inside the cartridge. (Includes methanol and methylene chloride)
• Cartridges should be selected and changed regularly according to manufacturers recommendations.

How Cartridge Respirators Work

The act of breathing creates a negative pressure inside the mask, which is why cartridge and dust masks are sometimes called “negative pressure respirators”. If the mask does not fit properly along the edges, contaminated air can enter. This is why fit-testing is essential when using these kind of respirators.
