Amazon now allows the sale of N95 and 3M masks on its marketplace platform. It previously banned the sale of these items due to low stock for hospital workers. However, supplies are still limited — and buying from third-party sellers can be risky.

How to choose the right 3M face mask

The CDC recommends not wearing surgical N95 masks if you are part of the general public to allow more supply for those on the front lines. However, nonsurgical N95 masks can offer some of the best protection against COVID-19 when worn properly.

3M has several types of masks available.

Mask typeWho’s it best for?DescriptionHow long does it last?
N95 nonsurgical masks Picture not describedPeople who are sick and caretakers. General public against Delta and Omicron variants.Blocks at least 95% of airborne particles when worn properly. Adheres to government testing regulations.Can be reused in certain situations, but must be discarded after coming into contact with bodily fluids, infected patients and in other circumstances. Read the CDC’s full reuse guidelines.
Respirator masks 3M respirator N95Construction workers. Not recommended for use against COVID-19.Blocks at least 95% of airborne particles when worn properly. However, the respirator potentially exposes others to infection.Can be reused in certain situations, but must be discarded after coming into contact with bodily fluids, infected patients and in other circumstances. Read the CDC’s full reuse guidelines.
Cloth face masks 3M cloth maskThe general population when in a public space, over a surgical mask when an N95 is not available.Typically made from cotton fabric with elastic or tie straps. Some designs have a bendable nose piece to create a tighter fit to the face.Can be washed and reused for weeks or even months, as long as the material maintains its integrity.

3M and the Defense Production Act

In April 2020, the Defense Production Act required 3M to prioritize orders from the Federal Emergency Management Agency (FEMA) for N95 respirators. FEMA then organized sending these N95s to those who needed them most as protection against COVID-19 — primarily healthcare workers, first responders and frontline personnel.

As 3M and other manufacturers worked to scale their manufacturing capabilities and meet the demand for supplies in essential fields, this left some lines of 3M masks hard to find for consumers. But now, manufacturing capabilities in many facilities have scaled to meet demand in many areas, and you can again find nonsurgical N95 masks on store shelves.

Can you buy N95 masks at these stores?

Home hardware stores like Lowe’s, Ace and Home Depot regularly stock nonsurgical N95 masks, mostly for construction purposes. You can also order N95 masks from online providers like Amazon. If you’re looking to buy N95 or KN95 masks specifically, check our page on in-stock sellers.

3M vs. Makrite masks: What’s the difference?

3M and Makrite are different brands that manufacture similar personal protective equipment (PPE), including several types of face masks. These masks are often used in construction, painting and other professions where small particles can be easily inhaled without protection.

Are all 3M masks N95 masks?

Some types of 3M masks use an N95 respirator to filter out 95% of airborne particles. However, not all masks made by 3M necessarily have this filter. Check the mask’s product specifications to determine whether it contains a filtration device.

What does “3M” mean on a face mask?

3M is the brand name of the manufacturer that makes the face mask. “3M” is not a regulated designation like the term “N95” is.
