I train in the desert and it is always dusty. thanks** A: I have strictly used it on plane rides, and I've found I don't get sick and my allergies don't act up, that's how I know they work. The seal is good and I really don't see anything getting through the fabric type screen, it's worth a try. My apologies if this wasn't the answer you were looking for. **Q: How do I know what size to get?** A: I have a small face and nostrils, so the small works for me. But I've also used the mediums which are a little large, but still do the job. My family and I mainly use them on airline flights and appreciate not coming down with colds and flu from contact with airborne illnesses through the recycled air. **Q: Worth the price? Reusable?** A: Worth the price? Yes. Reusabe? Yes and no. I get away with using them twice because I only used them when I sleep. I just keep the plastic the come one and stick it back on. Anything longer than 2 night they just fall off. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars These Things Really Work! *by S***N on Reviewed in the United States on August 29, 2015* Well, they work within limitations. But they work better than anything I've ever tried for what I want then for. All kinds of smoke, particularly cigarette smoke causes me problems. 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. In the past that has been an immediate headache, or worse, for me. 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. 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. But they work great for every day!I read the reviews, and one person who is a senior citizen said they didn't work for her. Well, according to the government, I'm a senior citizen-that is if the receipt of Medicare counts. I suspect that there was some other reason this person couldn't use them.I have tried all kinds of things to filter my breathing and lessen my exposure to allergens. Surgical masks can be hot and uncomfortable, and are definitely unsightly. Masks do next to nothing to reduce smoke for me. I tried several different kinds of carbon filter masks. 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. Another one worked temporarily, but didn't last long at all and had to be frequently replaced in order to continue working. All of them were at least as unsightly as the surgical masks (one was worse). I tried filters that are inserted into the nose, but first I couldn't find the correct size. After trial and error, I concluded my nostrils are different sizes. If I get them to fit one nostril, they hurt in the other one. Once they even caused bleeding. And they really lowered the amount of air I was getting, and didn't filter the smoke as well.I believe my allergies are pretty bad. I doubt that I will ever be totally free of medication. Right now I'm taking one antihistamine and have two inhalers-one rescue inhaler, and one steroid. I don't mean to be complaining, but I feel a burning sensation in my nose, and sometimes even down into my lungs if I accidentally breathe in smoke. But, with First Defense, I can tell a difference in my breathing, and notice less coughing. And the big thing-I even forget I'm wearing them sometimes unless I go by a mirror.. ### ⭐⭐⭐⭐ 4.0 out of 5 stars ... my trip to China (the pollution there can be pretty awful) as an extra layer of protection if I ... *by V***E on Reviewed in the United States on April 6, 2018* I bought this for my trip to China (the pollution there can be pretty awful) as an extra layer of protection if I forgot to put on my mask. I also used it during work meetings so that it's not as obvious and it worked pretty well. The stickers were easy to put on and I didn't have much trouble fitting it around my nostrils. It will take some time adjusting to the breathing with this blocking most of the air flow but I think in general, it served its purpose. ### ⭐⭐⭐ 3.0 out of 5 stars Not impressed *by R***S on Reviewed in the United States on June 24, 2020* Just not impressed. Didn't fit well and came off too easily. I can't comment on the effectiveness of the filter because I couldn't get comfortable wearing them. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/14371019-nasal-screens-4-pack-medium](https://www.desertcart.kr/products/14371019-nasal-screens-4-pack-medium) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-24*
