100Pcs PM2.5 Filters 5 Layers Activated Carbon Filters,Adult for Outdoor Activities Replaceable Anti Haze Filters Breathing Insert

While I was visiting my dad, he decided to order some cloth masks, and these are the PM 2.5 with a filter insert. He has a lot of health issues and was tired of wearing disposable masks that do not block smells. He was very pleased with these filters actually blocking perfume, fragrances and smells from the store and they are not to hard to breathe through. He didn't realize how much they blocked until he took his mask off. As with any thin carbon paper filter they don't block 100% of smells, but I would say they block 85-90% of fragrance and chemical odors, they worked very well for the smoke we recently had from Canada. I use them myself and I would highly recommend them.

Nicely made. I like that you get 100 for a decent price.

We have purchased several packs of these charcoal filters for cloth facemasks since covid began. They hold up well, filter out virus and pollen sized particles, are easy to change in the masks, and are a great value for the money. Since using these filters and wearing masks, we have had far fewer allergy issues, as well as cold and flu seasonal illnesses.

They are good filters.Although they are somewhat difficult to put into the mask. They say that the filters need to be changed after each use. That is not what the authorities say. They can be used up to one or two weeks.It depends on why you are using them and the environment you are using them. Perhaps they want you to use them up faster so you can buy more.

Works for me!

Not really much to say. It's a lot of mask filters for a little bit of money and cheaper than in store where they hardly sell them anymore.

Love these
