30 pcs Activated Carbon Filters | 5 Layers Protective Filter Replacement Anti Haze Filter Paper Protective Mouth Filter for Outdoor - 30pcs - pm 2.5 Filter

The filters arrived with minimal packaging - always a good thing - in perfect condition. They are strong and quite thick yet flexible and breathable. I have washable / reusable cloth masks without filter pockets and find just placing a filter inside feels and comfortable works fine as long as you aren't a mask on a chin wearer - which I am not. I fold the mask plus filter in half and put it in a zip up make up bag between uses, airing it when I get home. The two I have used have lasted weeks so far but that’s for occasional shopping, going to the park etc. so not all day, everyday. I feel better protected by adding a good filter and may even venture onto a London bus with one at some point (so many people are chin wearers on busses, so not a COVID safe environment.) The addition of charcoal filters in these is great because they are good for filtering out finer airborne particles which could otherwise penetrate thin masks. The odd lipstick stain gets onto the filters rather than the cloth mask so another plus since they can be discarded and replaced. Pack of 30 (3X10) good value and handy.

Arrived promptly and fit the pockets in masks/face coverings for added protection. Helps to give a bit more structure to some of the stretchy coverings.

Perfect filter replacements for my masks

Time will tell if we contract Covid ..They seem well made and fits snuggly in the reusable mask we have .If you suffer with claustrophobia it maybe a problem. Breathing is difficult. Because of the layers.. this is why they are 3ply + ..We don't want anything passing through. Would highly recommend quick delivery well packaged.

Arrived quickly.Filters fit most facemasks with a pocket. Honestly, not sure whether they are what they purport to be or how to check that, or how effective a protection they provide anyway. However, my wife and I have used them because it’s something we can do, and so far so good.

Despite not being particularly well-packaged these carrbon filters arrived promptly and are perfect replacements for the filters supplied with my face-masks. I may order another batch if the need arises.

Package arrived on time, product was as described, fits my mask well. Not much else you can say really.

Purchased for use with a false mask that can take filters. I received the 30 pack which was better value and this was checked out by the seller to make sure I’d received the correct sized pack. Thank you!
