AirWeave ชุดกรองทองแดง

The filters themselves work fine and fit the masks, but my main gripe is some of the packages arrived with it split open at the sealed side seams. The paper packaging says a filter will remain good as long as it remains sealed, but it kind of sucks that the adhesive holding them shut will come undone before I'm even ready to use them. Not sure how effective these filters will be when I go to use them since these things are only reported to be effective for a max of 20 days after opening and it's been longer than 20 days since this arrived opened already. Not sure if it's just the dry + cold climate I live in that's making the adhesive not hold well but it's a shame if I'm not getting the best protection because of this.

Extra filters can be used when needed

Nicely packaged, not actually good for 20 days if you are using them for many hours a day

Supposed to last 20 days but I get them very dirty in 4-5 days. Tried washing them but it made them very fuzzy and uncomfortable

These filters seemed to do the job. I used the mask for the first time recently. The head strap needs to be changed. Very bulky and didn’t sit like the video showed. I used it return to Denmark so 20hrs each way and it was frustrating. I can’t wear the ear loops. Please look at the design again. A dedicated head one would be much better than this clip on one. Didn’t get sick so it must have worked. Fit was smooth but mask looked big at the top and hard to read with. There were no gaps but it looked bulkier than the fitting pictures.
