Good value for bulk buying
Bought these for our construction crew. They work well for general dust protection. One star off because the packaging was slightly crushed upon arrival, but the filters inside were fine.

Solid performance
Do exactly what they are supposed to do. Breathing resistance is minimal even after a few hours of use. Will purchase again when these run out.

Essential for renovation work
Using these during a home renovation. No more coughing after a day of drywall work. Highly recommend pairing them with the 3200 series mask for maximum comfort.

Thick and durable
These feel much thicker than the generic ones I bought at a local hardware store. They last longer before needing replacement, which saves money in the long run.

Fast shipping and great product
Arrived earlier than expected. The free shipping was a nice bonus. Filters are high quality and provide peace of mind when working in dusty environments.

Perfect fit for my old mask
I have a pair of 3200 masks that are years old, and these filters fit perfectly. The airflow is good, and they seem to trap dust effectively while sanding wood in my shop.
Q: Are these filters reusable or disposable?
A: These 3701CN filters are disposable. They should be replaced when breathing becomes difficult, if they are damaged, or if they become contaminated with oil or other substances not covered by their rating.
Q: How many pairs come in one package?
A: This specific listing includes 10 pairs (20 individual filters) in one box, which is sufficient for extended projects or multiple users.
Q: Can these protect against paint fumes?
A: No, these are particulate filters designed specifically for non-oil based dusts like sanding debris or concrete dust. For paint fumes or organic vapors, you would need a cartridge rated for organic vapors (such as the 6001 series).
Q: What is the expiration date on these filters?
A: Our stock typically has a shelf life of 3 years from the manufacturing date. Please check the stamp on the side of the box upon receipt for the specific batch expiration date.
Q: Will these fit the 3M 6200 series masks?
A: Yes, the 3701CN filters are designed to be compatible with the 3200, 6200, 6500, and 7500 series half-facepiece respirators that use the bayonet-style connection.
