Adult PM2.5 Activated Carbon Filter 5 Layers Replaceable Anti Haze Filter Paper (200PCS)

I like these filters - I would have given them 5 stars all across the board if they were not so expensive. I buy them because I feel they add extra protection to my regular cloth mask. The filter fits right in the pocket.

We received what appeared to be dirty and used filters. Some even had nasty black finger prints on them and brown spots. I dont recommend this product. With a pandemic going on in the world I dont feel comfortable using them.

very good

Good quality

Love these filters, feel very secure with them in mask

Great product and good quality

Fits well in my mask

No package labeling at all. No idea where or who this came from. I am not comfortable with that. This is a health product and there is no business or product name or company. I want to return this

comfortable and my glasses dont fogged up.

Refill difficult to insert to the mid point
