I tried filters that are inserted into the nose, but first I couldn't find the correct size. All of them were at least as unsightly as the surgical masks (one was worse). Another one worked temporarily, but didn't last long at all and had to be frequently replaced in order to continue working. One, which worked temporarily, was heavy and uncomfortable, and caused me to have an upper respiratory allergy when I left it on a long time. I tried several different kinds of carbon filter masks. Masks do next to nothing to reduce smoke for me.

Surgical masks can be hot and uncomfortable, and are definitely unsightly. I have tried all kinds of things to filter my breathing and lessen my exposure to allergens. I suspect that there was some other reason this person couldn't use them. Well, according to the government, I'm a senior citizen-that is if the receipt of Medicare counts. I read the reviews, and one person who is a senior citizen said they didn't work for her.

I really haven't used these for a rapid walk yet, so I don't know if I'll still be able to get my breath then. In this kind of situation, I don't even smell the smoke when I have these on! And now I have them in a smaller size which fits me better. In the past that has been an immediate headache, or worse, for me. I needed something that would help if I was suddenly was exposed to unexpected cigarette smoke-for example, in a drive thru and someone lights up in the car ahead off me while I have my window down. All kinds of smoke, particularly cigarette smoke causes me problems. But they work better than anything I've ever tried for what I want then for.
