Do carbon/charcoal filter masks help your MCS?

For the unfortunate people out there who have recently developed MCS and are struggling to cope with the onslaught of chemicals and feel overwhelemed, I just wanted to report that when my MCS was at its worst I found carbon filter masks to be a real lifeline.
Despite being acutely sensitive to everything from household cleaning products, personal care products, gas stoves, vehicle exhaust, newspapers/magazines and practically anything recently manufactured...when wearing a carbon filter mask I could be around people wearing their deodourants and perfumes, I could walk outside among the vehicle exhaust and fumes from neighbours' dryers and central heating boilers, and I could even visit public places. You get a lot of stares sat in a cinema wearing a face mask...but at least you can enjoy a movie!
The mask I used was from www.icanbreathe.com (no financial interest) and I found the fit to be perfect. The only downside was it got very sweaty in there.
How have other MCS survivors out there found carbon face masks? Have they been as much help for you as I found them to be? Which brand did you use?
It would be good to get some more experiences out there for the newbies or those who are still struggling for any kind of relief...
This one failed me when needing to take a cab filled with febreze... the driver showed me the can he opened all the windows and I put my head out but it was too late I am still trying to recover.
I have bought two 3m respirators filters easy to get... P100 NIOSH filter... bit leary now of how well it will actually work....
What can stop febreze? Anything?
Another thing I've tried is swimmer's nose plugs. These completely block the smell and allow me to keep that nose muscle relaxed, but they tend to give me a headache and ear aches from the pressure each time I swallow. Plus, they kinda hurt.
I'm looking for a better mask with a different filter but so far nothing is out there.
I'm going to order the icanbreathe mask, thanks mcscanary. I'm so so looking forward to getting back to play bridge especially.
The icanbreathemask have been a God send for me, without them I would not be able to endure grocery stores, target stores (super yuck as target is so toxic) and the most important is that I am allowed to wear these at my work place and am on the phone all day with my mask on and it does not impair the quality of my voice at all. Love the product. I have the one that is beige lace with the beautiful rose on the side of it, I get compliments on it every time I go out and people want to know about why I wear it and where they can get one too. I carry brochures and business cards with me that I hand out. I am in no way affiliated with that business just love the product so much that I want to share with others the benefits that I have gained from using it daily : )
