فلاتر استبدال القناع Werx

Switching out the old filter for one of these was quick, and I can really tell the difference in air quality during my commute—the carbon layer seems to be doing its job. Fits perfectly into the mask without any gaps.

The activated carbon layer actually makes a difference in how fresh the air feels compared to cheaper single-layer filters. I've been using one for a week and it's holding up well through my daily commute.

I was worried about air quality on my commute, but these five-layer filters fit perfectly and the activated carbon layer really cuts down on that stale subway smell. They’re easy to swap out and I notice a real difference in how clean the air feels.
