For haze dominated by fine particles, a properly fitted, correctly worn NIOSH-approved N95 particulate respirator offers better particle protection than a loose-fitting surgical mask. Surgical masks are not designed to seal to your face or filter smoke particles in the same way. An N95 is not protection from every component of haze or smoke: it filters particles, not harmful gases or vapors, and it does not supply oxygen.
How N95 respirators and surgical masks differ
| What matters | NIOSH-approved N95 | Surgical mask |
|---|---|---|
| Purpose and approval | A particulate respirator tested and approved by NIOSH. EPA says its filter is more than 95% efficient at removing wildfire-smoke particles in the PM2.5 size fraction; that is filter performance, not a promise of the same reduction in personal exposure or health risk. EPA guidance | Not a substitute for a NIOSH-approved particulate respirator for smoke particles. CDC/NIOSH says surgical masks are not designed to seal to the face or use the type of filter material that filters smoke particles. CDC/NIOSH guidance |
| Fit and air leakage | Works as intended only when the model fits closely and is worn correctly; gaps can let unfiltered air in. Fit varies by face and model. | Loose-fitting and not designed to form a tight face seal, so air can pass around the edges. |
| What it does not address | Does not filter harmful gases or vapors and does not provide oxygen. | Does not provide the smoke-particle protection of a well-fitting approved respirator; do not assume it protects against gases or vapors. |
EPA’s figure describes N95 filter efficiency under the stated particle-size context, not a clinical result or an estimate of how much a wearer’s exposure or health risk will fall. Real-world benefit depends on fit, correct use, exposure, and other conditions. WHO says evidence on public use in real-world conditions is limited, including because studies are few and often lack adequate fit information. WHO guidance
Choose a respirator that is approved and seals to your face
- Look for a two-strap particulate respirator with “NIOSH” and “N95” or “P100” printed on it. Check for approval by a recognized authority; labels alone are not proof that a product was properly tested. EPA recommends NIOSH-approved respirators, and WHO cautions that products may claim protection without proper testing. EPA guidance WHO guidance
- Choose a model and size that covers your nose and sits under your chin with a close seal. A model that fits another person may not fit you.
- Facial hair where the respirator touches the skin can interfere with the seal. If air leaks around the edges, try a different size or model.
Put it on and check the seal each time
- Follow the manufacturer’s instructions. Place the respirator over your nose and under your chin.
- Position one strap above and one below your ears. If it has a nosepiece, press it into shape with both hands.
- Check the seal every time you put it on. If you feel air leaking around the edges, adjust it or try another model; do not assume that a respirator that fitted before still seals properly.
- Replace it when it becomes dirty or harder to breathe through.
Reduce haze exposure before relying on a mask
When smoke is present, reducing time outdoors is the most effective wildfire-smoke protection in EPA’s guidance. Reduce strenuous activity and use indoor measures such as a portable air cleaner to lower exposure. If you must be outdoors in unhealthy smoke conditions, a properly fitting NIOSH-approved particulate respirator can reduce exposure to smoke particles; it does not remove every component of smoke. EPA guidance
Account for health, heat, and children
Respirators can make breathing harder and may contribute to heat-related illness in hot conditions or during physical activity. EPA advises people with heart or lung problems, or who are pregnant, to consult a clinician before using one. Take breaks and drink water in hot weather or during activity. If wearing a respirator causes breathing difficulty, dizziness, or other symptoms, move to cleaner air and remove it; seek medical care if symptoms persist or are severe.

CDC says children aged two and older can wear respirators, but fit, comfort, vision, and the child’s ability to wear one correctly matter. EPA notes that NIOSH-approved models are not available in sizes suitable for young children, so do not assume an adult model will fit. CDC/NIOSH guidance EPA guidance
