Replace The Filter, The Nose Filter Device Health and Safety Effective Filter Device Filter Out Pollution 30pcs

These disposable filters are a great option if you want to add an extra layer of protection to any mask. They have stickers in the back so they stay securely in place. They are thin and not as soft as other brands, but they have a very good price and fast Prime delivery fulfilled by Amazon! Happy with my purchase.

These are very thin, and in hindsight there aren’t really any specifications given in the description. None came with the product. I won’t trust them for added COVID protection. They are just in a plain bag with no writing. I’ll use them only in very low risk situations unless the seller adds more info.

No instructions on how to put in mask. I used scotch tape.

Fits very comfortably

No

I purchased the Replace The Filter, The Nose Filter Device Health and Safety Effective Filter Device Filter Out Pollution 30pcs because I am required to wear a mask daily and I wanted to have just a bit more protection. This slips easily inside the mask I am wearing and provides extra filtration. I am using 1 per day on the days I wear a mask. It is lightweight and easy to use and makes me feel a lot better with the extra layer.

These are not what they seem to be. It is. I am very disappointed in this product. I thought they would be more like the 925 filters

These are good filter replacement, works good to protect from dust and pollution.The quality is good and effective.
