50 Pcs 5 Layers Replaceable Filters PM2.5 Activated Carbon Filter, Protective Mouth Filter for Outdoor

I use a Leovard adjustable mask that came with three PM 2.5 filter inserts. The mask has a pouch in which the filters fit. Since the mask only came with three filters, I looked on Amazon to find additional filters. These are the ones I selected based upon their description and price.Now that I have them, I have taken one apart, and also took apart one of the three filters that came with the mask. They use the same five part construction - a quilted exterior, then smooth paper, then the carbon paper, then another smooth paper, and finally another quilted exterior. Although the layers are the same, these filters feel a little thicker than the ones that came with the mask - although both seem to work just fine.

These are by far the best filters in terms of quality that I have ordered. I received some others that were paper thin and poorly packaged to where the product was compromised. Threw them ou. These fit perfectly inside of the pocket on my reusable washable masks and provide an extra barrier for safety. Very well made and good quality. I keep ordering. Would recommend

Easy to change out, bought it because more or less masks are required when in public. Don't know how long this COVID 19 will last..

These are to small for an adult face mask.

These have worked well with the cloth mask I bought. They are thick, and sometimes a little difficult to breath through( there seems to be like a plastic backing on it) but that's just the problems wearing anything over your face creates. These are a real value for the money if you want extra protection for your cloth face mask.

I specifically searched for made in America masks and filters I got these on time the math doesn't have an insert for the filters like it suggested and the filters are made in China like I trust China so much right now is anybody tell the truth about where things are coming from anymore

I like these. I don’t not feel like I can’t breathe with these in my mask and I’m extremely claustrophobic.

The mask has multiple layers. It would filter allot if it fit properly. Instead it fogs up your glasses with every breath. Very hot also. Since with air, it follows the path of least resistance, some type of liner along the top may be helpful. Fabric does feel nice.

Fast shipping and item is as described. The filter is easy to use and fits well in my cloth face mask.
