Solid choice for DIY
Using this for home renovation projects. Works well for drywall dust and insulation. Just make sure your mask model is compatible before buying.

Comfortable and effective
I was worried about breathing resistance, but these are surprisingly easy to breathe through. No dust gets through even in very dusty construction environments.

Great value and protection
Bought these for sanding wood in my workshop. The KN100 rating gives me peace of mind. They fit snugly on the mask and don't leak air around the edges.

Good but replace often
Excellent filtration, but if you are doing heavy grinding, you need to change them every few days. Still, for the price, they are the best option available.

Perfect for welding jobs
These filters work great with my 3M 6200 mask. I use them daily for welding and they handle the fumes without making it hard to breathe. Highly recommend for any metalworker.
Q: Are these filters compatible with the 3M 7502 half-face mask?
A: Yes, the 2091/2097CN filters are fully compatible with the 3M 7502 series, as well as the 6000 and 6500 series.
Q: Do these filters protect against organic vapors or paint smells?
A: No, these are particulate filters only (KN100). For organic vapors or paint smells, you must use them in combination with an organic vapor cartridge like the 3M 6001.
Q: Can these be cleaned and reused?
A: No, these are disposable filters. They cannot be washed or cleaned. Once they are clogged or damaged, they must be discarded and replaced with a new pair.
Q: How long does one pair of filters typically last?
A: Lifespan depends on the concentration of dust and your breathing rate. Replace them when breathing becomes difficult, they are damaged, or according to your workplace safety schedule.
Q: Is this product certified for use in China?
A: Yes, the 2097CN model specifically meets the GB2626-2019 KN100 standard required for certification in China.
