Comfortable and effective
Very happy with this purchase. The cotton material feels softer against the face compared to synthetic alternatives I've tried. Breathing resistance is low, which is great for long shifts.

Essential for renovation projects
Bought these for a home renovation involving drywall sanding. They handled the fine powder incredibly well. My lungs felt clear even after a full day of work. Highly recommend stocking up.

Great value for workshop use
I use these filters daily in my woodworking shop. They fit perfectly into my 3701 mask and last a good amount of time before needing replacement. The thickened material really seems to catch fine dust effectively.

Perfect fit for my old mask
I was worried these wouldn't fit my older model mask, but they snapped right in. No gaps around the edges. I feel much safer knowing I have thick padding against concrete dust.

Solid industrial grade filters
Using these in a welding environment for light sparks and smoke particulates. They hold up well and don't clog immediately like cheaper brands. Only downside is the packaging could be more robust.

Good filtration, slightly stiff at first
These filters work well for grinding metal. They were a bit stiff out of the box, making breathing slightly harder initially, but they softened up after about an hour of use. Good protection for the price.
Q: How many filters come in one package?
A: Each package contains 50 individual thickened filter pads, providing a substantial supply for regular industrial or hobbyist use.
Q: Are these filters reusable or disposable?
A: These are disposable filter pads. Once they become clogged with dust or make breathing difficult, they should be discarded and replaced with a new one.
Q: What is the shelf life of these filters if unopened?
A: If stored in a cool, dry place away from direct sunlight and extreme temperatures, unopened filters typically maintain their efficacy for up to 3 years from the date of manufacture.
Q: Do these fit the 3700 series masks from other brands?
A: These are designed specifically for the 3701cn model. While they may fit similar 3700-series half-face masks, we cannot guarantee a proper seal with incompatible brands.
Q: Can these filters be used for painting or spraying chemicals?
A: No, these are particulate filters designed specifically for non-oily dust like wood, metal, and concrete. They are not suitable for organic vapors, paints, or chemical sprays.
