PM2.5 Replaceable Filters for Adult (50 PCS)

The product is comfortable to use and fits snuggly into the mask's slot. I find the disposable blue masks a little more easier to breath with. Opting for pm2.5 filters for better protection and to reduce the environmental impact of the one-time-use masks. But I'm not sure how much of protection I'm getting, considering the tiny holes on it, as shown in the picture.

Though it was a little smaller than I anticipated, it has held up well. I've been using them for the last 5-6 months and am yet to catch anything. They feel of good quality and the stitching is really good too. They've lasted quite a while. I would definitely recommend these.

Fits well into face mask. No issues.
