I have two Cambridge masks, one about three years old and one about 6 months. I have an increasing problem with indoor air pollution, from cooking fumes, wood burners, candles, air fresheners etc. I have found that my first one can really be a boon when I encounter these things and I can feel the warning signs from whatever PMs or VOCs are about. I don't use them for Covid, just for indoor air pollution issues.
My second one, however, which I used for the first time a few days ago seemed to cause me a mildish asthma attack (two lots of Ventolin and a lot of exhaustion) . There seemed at first to be some fleeting sweet smell from it as I opened the little blue box, like air freshener or fabric softener or some such, but as it was fleeting I forgot about it. However eventually it seemed at first to cause irritation that caused a cough, and later breathlessness and that familiar exhausted feeling. I am by now quite used to wearing masks so I don't think that was the issue.
Has anyone had similar issues with the Cambridge Mask specifically? Also, if I have to change brand, what other masks to manage pollution have any of you found? After that little episode I am a bit wary of spending money on something I don't have a recommendation for.
