Sundstrom SR221 Pre-Filter

The Sundström SR221 Pre Filter is designed to capture larger dust particles and contaminants before they reach the main particle filter, helping extend filter life and maintain effective respiratory protection.

Easy to install and replace, the SR221 fits into the pre-filter holder, which then snaps securely onto a compatible Sundström particle filter or combined filter. This pre-filter helps reduce premature clogging of the main filter, making it a practical and cost-effective addition to your respiratory protection equipment.
