- A disposable prefilter designed to capture larger, coarse particles before they reach the main HE particulate filter
Uses
- Heavy Particulate Environments:
- Ideal for industries where workers encounter high amounts of coarse dust, sawdust, or debris (e.g., woodworking, grinding, or general industrial applications)
- Filter Protection:
- Used exclusively in the 3M TR-300+ Series PAPR Systems to intercept large debris upstream
Features
- Genuine Accessory:
- It is a NIOSH-approved component of the TR-300 PAPR ecosystem
- Slim Design:
- Fits neatly inside the filter cover without adding bulk to the belt-mounted blower unit
- Maintenance-Free:
- The prefilter requires no cleaning; it is designed to be discarded as soon as it becomes clogged or damaged
Benefits
- Extends Main Filter Life:
- By intercepting large-to-coarse particulates, it prevents the primary HE filter from clogging prematurely
- Cost-Effective:
- Because prefilters are significantly cheaper to replace than the primary High Efficiency (HE) filters, swapping them frequently protects your investment and drives down overall operating costs
- Consistent Airflow:
- Prevents the main filter from reaching maximum airflow resistance too quickly, which maintains consistent battery life and comfort for the wearer
