SUNDSTROM SR 221 Pre-Filter Selection Notes
Use this item as part of a hazard-based respiratory protection programme. For Malaysia and Singapore workplaces, start with the exposure assessment: contaminant type, oxygen level, concentration, work duration, wearer suitability and emergency scenario.
Where It Fits
| Product range | respirator cartridges and filters |
| Typical use | Respirator cartridges and filters must match the airborne hazard. |
| Selection note | Choose filters from the SDS and exposure assessment. Filter colour, class and product name are helpful clues, but compatibility, service life, breakthrough risk and changeout schedule matter just as much. |
Standards and Procurement Notes
DOSH lists respiratory protective filters under standards such as EN 143, EN 14387 and BS EN 149 depending on product type. Verify approval, shelf life, compatibility and changeout requirements before use.
