* Important information form Sundstrom regarding filter use: 

  • Change the pre-filter SR 221 at least every 7 days.
  • Change particle filter SR 510 (P100) after 18 months or sooner if there is any concern regarding physical damage, hygiene (dirt, soil) or increased breathing resistance.  

The SR 221 pre-filter is a non-classified filter media designed to capture coarse and larger particles while extending the life of the particulate filter SR 510 and SR 710. The pre-filter is placed in the prefilter holder which attaches to the particulate filter.
