Tanness 20x Mask Filter Replacement, Protective Filter, PM2.5 Protective Filter 5 Layers Replaceable Anti Haze Filters for Mouth Masks

Excellent product bought for my face mask as I am a high risk person so I feel safe going out with this product .🌈🌈

These masks are terrific. Great fit especially over bridge of nose - no slipping. I sent 2 to my sister as she was not happy with ones tried. Well worth the money and wash well for reuse..

Prompt delivery Original packaging Good quality filters I received 20 (10 + 10 in 2 separate plastic bags) in a pack Happy with this purchase

Great job of filtering out the carbon

Ordered for public transport as returning to work.It's a little on the small side but I've gotten used to it. It absolutely will steam you glasses up though. That quest continues

I have no idea what the criteria are for judging the operation of a mask filter without access to scientific tests and equipment. So all I can really say here is that these arrived quickly, were very sensibly packed, fit into my mask well and appear to do the trick.

Arrived on time and filters as described - fitted easily into the masks I have. Good price

Fits perfectly into my new homemade mask, value for money, and I have a nice stock now just in case we have to use them more extensively in the future.
