Miller PAPR II HEPA Filters and Pre-Filters Overview
The Miller PAPR II HEPA filters and pre-filters are the replacement filter media for the Miller PAPR II welding helmet powered air-purifying respirator. The HEPA particulate filter captures 99.97% of airborne particles as small as 0.3 microns, including weld fume, mist, and dust, and the nuisance organic vapor pre-filter reduces odor and helps extend the HEPA filter's life.
As the Miller PAPR II HEPA filter set, this Miller 287170 filter is the Miller PAPR filter and PAPR II pre-filter for the system. As a Miller PAPR HEPA replacement, the HEPA is a particulate filter only, so the pre-filter's organic-vapor treatment is odor relief, not protection.
These filters are consumables for the Miller PAPR II welding helmet. Browse the range in PAPR respirator filters, powered air-purifying respirators, and welding respirators.
What These Filters Are For
| Need | Fit | Buyer guidance |
|---|---|---|
| Weld fume, mist, and dust | Purpose-built | HEPA captures 99.97% down to 0.3 microns. |
| Extend HEPA filter life | Strong | Pre-filter catches larger particles first. |
| Nuisance odor comfort | Strong | Pre-filter adds nuisance organic-vapor odor relief. |
| Organic vapor at or above the limit | Not suitable | Odor relief only; use a rated respirator. |
| Original PAPR or PAPR II blower | Both fit | The 287170 HEPA fits both blower generations. |
A filter only works within a complete, matched, compliant system. The Miller HEPA filter is a particulate filter, so it captures weld fume, mist, and dust but does nothing for gases or vapors; the pre-filter's organic-vapor treatment is nuisance-level odor relief only, not respiratory protection, so organic vapor at or above the exposure limit needs a respirator rated for it. No filter makes a PAPR usable in an IDLH or oxygen-deficient atmosphere, which requires a supplied-air respirator or an SCBA. These filters are disposable; never wash them or clean them with compressed air, which damages the media. Verify airflow after changing a filter, replace filters on schedule and when airflow drops or odor breaks through, and use the system within a written program under OSHA 29 CFR 1910.134.

Pros & Cons
Pros
- HEPA captures 99.97% of particles to 0.3 microns
- Pre-filter extends HEPA life and adds odor relief
- Fits original Miller PAPR and PAPR II blowers
- Multi-packs for high-use welding programs
- Simple, tool-free replacement
Cons
- Particulate only; no gas or vapor protection
- Pre-filter odor relief is not OV protection
- Disposable; cannot be washed or reused
- Consumable; replace as airflow drops
How It Compares
These are the particulate filters for the Miller welding PAPR. Weigh the parts of the set:
| Component | Function | Protection | Best for |
|---|---|---|---|
| HEPA particulate filter | Main filter | Particulate 99.97% | Weld fume, mist, dust |
| Nuisance OV pre-filter | Pre-filter | Odor relief only | Extending HEPA life, odor comfort |
| Rated gas cartridge (separate) | Gas media | Rated OV/gas | Actual organic-vapor exposure |
Use the HEPA filter and pre-filter together on the Miller PAPR II, and add a rated respirator for real gas or vapor exposure. See our best PAPR welding helmet guide, the best PAPR respirator systems guide, and the respirator filter types explained guide.

Frequently Asked Questions
What are the Miller PAPR II HEPA filters and pre-filters?
They are the replacement filter media for the Miller PAPR II welding helmet PAPR: a HEPA particulate filter that captures fine particles, and a nuisance organic vapor pre-filter that reduces odor and helps extend the HEPA filter's life.
What does the HEPA filter capture?
The HEPA particulate filter captures 99.97% of airborne particles as small as 0.3 microns, including weld fume, mist, and dust. It is a particulate filter only and does not protect against organic vapors or acid gases.
Does the pre-filter protect against organic vapors?
No. The nuisance organic vapor pre-filter reduces nuisance-level organic-vapor odor for comfort and extends the HEPA filter's life; it is odor relief only, not protection. Real organic-vapor exposure needs a respirator and cartridge rated for it.
Which blowers do they fit?
The 287170 HEPA filters fit both the original Miller PAPR blower motors and the newer PAPR II blower motors. Confirm your blower generation, and match the pre-filter to the same system before ordering.
Why use a pre-filter?
A pre-filter catches larger particles first, which extends the life of the main HEPA filter and adds nuisance-odor relief. It is a low-cost way to reduce how often you replace the more expensive HEPA filter in dusty welding work.
Can I wash or reuse the filters?
No. These are disposable filters. Washing them or cleaning them with compressed air damages the filter media and compromises protection. Always replace with a new filter rather than trying to clean an old one.
What pack sizes are available?
The HEPA filters come in multi-packs such as 6-packs and 36-packs, and the nuisance OV pre-filter comes in its own pack. Choose the pack size that fits your replacement schedule and how many PAPR units you run.
Does the filter change what the PAPR protects against?
The PAPR is a particulate respirator with these HEPA filters. They do not add gas or vapor protection beyond nuisance-level odor relief, so for gases or vapors you need a respirator rated for that hazard, matched to your exposure.
Can I use them in an oxygen-poor or emergency atmosphere?
No. A filter never makes a respirator usable in an oxygen-poor or immediately dangerous atmosphere. Those conditions require a supplied-air respirator or a self-contained air-tank apparatus, and you must confirm the environment first.
When should I replace them?
Replace the HEPA filter when breathing becomes harder, when it is damaged or wet, or per your program and the Miller schedule, and change the pre-filter more often as it loads. Odor breakthrough means the nuisance media is spent.
Do I need a written respiratory program?
Yes. Filters and the respirators that use them are used within a written respiratory protection program under OSHA 29 CFR 1910.134, including training, medical evaluation, and maintenance. Follow the Miller manual for use and replacement.
How should I store the filters?
Store sealed filters in a clean, dry place away from contaminants until use, and follow any shelf-life guidance on the packaging. Inspect a filter before fitting it and discard any that are damaged or wet.
