3M 8210 review

What the 3M 8210 is

The 8210 is a disposable, cup-shaped N95 particulate respirator from 3M's 8000 series. 3M's listing text says it is NIOSH approved for at least 95 percent filtration efficiency against certain non-oil based particles, and describes a two-strap design with welded attachment points, cushioning nose foam, and advanced electrostatic media that is designed for ease of breathing. It is a standard, one-size model without an exhalation valve.

These details come from a distributor page that reproduces 3M's description and specification list, since 3M's own catalog page could not be read for this review. Check the pack in your hands for the NIOSH markings.

How to confirm it is a genuine NIOSH-approved N95

NIOSH says all approved respirators carry a testing and certification number, such as TC 84A-XXXX, printed on the respirator, and that the easiest way to confirm a product is to search the NIOSH Certified Equipment List by that number. NIOSH adds that a respirator labeled N95 without the required markings is not NIOSH approved and cannot be relied on for the same protection. Buy from a trusted seller and check the markings on arrival.

Using it in wildfire smoke, per EPA

EPA says the most effective step in smoke is to limit time outdoors, with portable air cleaners indoors as another help. When you must go out, it says studies show N95 respirators worn according to the manufacturer's instructions, including minimizing gaps between face and respirator, will significantly reduce exposure to smoke particles. EPA advises a respirator with two straps, a size that fits over the nose and under the chin, a tight-seal check using the package instructions, and a clean-shaven face where it touches the skin.

EPA also says to throw the respirator away when it gets harder to breathe through or gets dirty, and to ask a doctor first if you have heart or lung problems or are pregnant, since wearing one can make breathing harder. See our wildfire smoke guide for more on staying indoors.

Strengths and limits

The 8210 is a simple, widely used design that works well as a household stock item. A 20-pack lets you swap masks through several smoke days. 3M also says it is not cleared by the FDA as a surgical mask and is not fluid resistant.

The limits are shape and fit. A cup does not fold flat, so it takes more room than a flat-fold, and one size cannot suit every face. EPA says NIOSH approved respirators do not come in sizes suitable for young children, so this is an adult mask. If you cannot get a seal, try another size or model.

How it compares, and the verdict

On our N95 comparison, the 3M Aura 9205+ is a three-panel, flat-fold design that is individually packaged with an adjustable noseclip, which many people find easier to seal. Flat-fold boxes and valved masks such as the Honeywell DF300 and 3M 8511 sit alongside it. Compare prices on the day.

Verdict: a dependable, no-frills N95 for a smoke kit if you pass the seal check. Skip it if you have a beard, small or unusual face shape, need a child size, or want individually wrapped masks that fold flat in a go-bag.

Is the 3M 8210 NIOSH approved?

3M's listing text says it is NIOSH approved for at least 95 percent filtration against certain non-oil based particles. NIOSH says to confirm by checking the TC number on the respirator.

Can children wear the 3M 8210?

EPA says NIOSH approved respirators do not come in sizes suitable for young children. Children 2 and older can wear respirators, but fit and comfort must be checked, and an adult N95 may not seal.

How long can I wear one N95?

EPA says to throw your respirator away when it gets harder to breathe through or if it gets dirty. Follow the package instructions and do a seal check each time you put it on.

Does the 8210 have an exhalation valve?

No. 3M's specifications list the Exhalation Valve as No. EPA notes a valve can help if masks feel hot, which is the job of valved models such as the 8511.
