I love this plugs. I think they are fantastic. Buy the set's that have a variety of sizes to try them out with will be worth it. These work so well that I may not need to take my allergy medicines...I may try that. I have two sets that I switch out each day. I wash them at the end of the day, let it dry all night and wear the other pair for the next day. I like the ones that have the screen AND the filter (don't really need the charcoal filter). They do flare out your nose a little if you get the right size and the "pull out handle" does show a little...however, they are absolutely worth the little discomfort. You have to buy the right size...so buy the variety pack first. I had bought the rounder one and then the variety pack and found that I like the narrow ones better for my nose. Both worked well though.

I always think it is weird to see reviews that say something changed their lives. I figure that the review is from someone connected to the product. I have no connection with this product. It has changed my life. I stay at home most of the time because chemicals actually make me faint. I have been to allergists. They have said it is impossible to diagnose because it is something in the air that does not stay in the body. So, I always have a cane to help steady myself. I mask and double mask. I avoid anything that looks like there might be chemicals. But since I have used these, it is like I can breathe for the first time in my life. I am much more mobile. I still get sick from the chemicals, but where it would have been an instant splitting migraine with fainting, now it is a dull headache. I have tried every medicine. I have used all kinds of masks. This is the only thing that has really made a huge difference. I just wish I could get the replacement filters faster. But I have been using the trial pair for two weeks now and it is still working. I rinse it and then let it air dry. Then I used them again, filter and all. It works so far even though supposedly the filters only last a few days.

I got these to filter allergens and they do a good job of it. With the current hazardous air in the PNW in Sep 2020 due to all the west coast fires, I can attest to the fact that they filter most of the smoke smell out. Miraculous! The but comes into play when I talk about how easy it is to actually breath with them in. Which is just barely...Maybe my sinus passages are too inflamed already...but when I put these in, while I smell cleaner air, I can't get enough! I end up finding I've opened my mouth to catch a breath...which sort of defeats the purpose. Not the worst $13 experiment I've ever tried, but sadly I can't really recommend them even tho I gave them 4 stars. I REALLY wanted to like them!

I was recently exposed to black mold and almost died. We had to move and everything had to be sanitized before it could be brought into the new place. I was having trouble breathing so a mask was out of the question. These little suckers fit into the nostrils and stay put. I was able to handle the unpleasant smell of cardboard boxes and I could breathe thru the nose with no problem. I was amazed.

Not at all comfortable, needs a more flexible material. Also not enough air flow to maintain normal breathing.
