Essential for construction work

I use these daily on construction sites. They last a good amount of time before needing replacement and keep the dust out effectively. Highly recommend for professionals.

Good value for bulk purchase

Buying the 10-pack is much more economical than single units. They work well for painting projects. I deducted one star only because the packaging was slightly crushed upon arrival, though the filters inside were fine.

Perfect fit for my 3M mask

These filters snap on easily to my 3M 6000 series respirator. They provide excellent breathing resistance balance and seem very effective against wood dust in my workshop.

Great for home renovation

Used these while sanding drywall and removing old insulation. My lungs felt protected and I didn't experience any irritation. Will definitely buy again for future projects.

Genuine 3M product

Verified the authenticity code on the box and it checked out. It's hard to find real 3M filters sometimes, so I'm glad this seller stocks genuine items. Breathing is easy even after hours of wear.

Works as expected

Standard replacement filters that do exactly what they are supposed to. No complaints about performance. Just wish they came in a resealable bag to keep unused ones cleaner.

5 FAQ

Q: Do these filters protect against paint fumes or just particles?

A: The 5N11 filters are specifically for particulates like dust, mist, and fumes. They do not filter organic vapors or gases. For paint fumes, you must use these in combination with an appropriate organic vapor cartridge (like the 6001).

Q: Is there an expiration date on these filters?

A: Yes, unopened filters typically have a shelf life of 5 years from the manufacture date printed on the box. Once opened and used, their lifespan depends on usage conditions rather than a fixed date.

Q: Can these be cleaned and reused?

A: No, the 5N11 particulate filters are disposable and cannot be cleaned or washed. Attempting to clean them will damage the electrostatic charge that captures particles, rendering them ineffective. They must be replaced when dirty.

Q: Are these filters compatible with the 3M 7500 series half-face respirator?

A: Yes, the 5N11 particulate filters are designed to be compatible with all 3M Half and Full Facepiece Reusable Respirators, including the 6000, 6500, 7500, and FF-400 series.

Q: How often should I replace these filters?

A: Replacement frequency depends on the concentration of contaminants and your breathing rate. Generally, replace them when breathing becomes difficult, or if they become damaged, dirty, or wet. For heavy dust environments, this might be daily or weekly.
