Muy buenos aunque un poco dificiles de poner, si fueran menos planos seria mas facil pero ya con practica no batallas tanto

Great 👍stuff

5 stars across the board. Not a fake review. I was looking at all the different sellers and kinds for awhile and decided to get these because they made of soft plastic with a 3M filter inside and because you get 10 of them. These are created made in the USA. I got them for allergies cause it's super bad here in Oregon right now. I got the Large size because I want them to not fall out like some people complained about in the comments. My nostrils are a medium but don't get what you think you need, get the next size up like I did. They fit snug inside my nose and stay in place. You do have to remove them from time to time to blow your nose but because of allergies and that's expected. I can totally breathe super easy like as if they weren't there. These are comfortable and don't hinder anything. Thank you for making a great product I can wear that doesn't fall out and I can use for these absolute horrible allergy times as this year pollen is super bad. I no longer have to wear a mask.

Not sure if this works, people unfortunately see it and ask about it and it doesnt stay all day so you would touch it with your hand and that is not good

I am now satisfied with these but you should basically ignore the fitting guide. These are meant (apparently) to be fully inserted in the nostrils with the plastic half-ring tight against your septum. For me - as soon as i tried fitting them this way it wasn't long before at least one of the filters would turn side-ways in one of my nostrils resulting in ineffective filtration. There doesn't seem to be anything to grip them and keep them in place when fully inserted. However - what i noticed was is that there is a groove in the design of the filters. I found that by inserting them at the very edge of my nostrils i could get this groove to slot in-between and grip the cartilage at the entrance of the nostrils. I have demonstrated this with some pictures that i have added. Once slotted in place at the entrance of the nostrils they stay put (at least for me) but ONLY if you purchase a size one size larger than actually fits you. I initally bought the medium size - which was about the right size for me and although these slotted in ok and were comfortable there was still enough 'play' in them to eventually work themselves loose, (but not always). I then bought the large size - at first i found them uncomfortable as they really did stretch my nostrils but i soon got used to this. I also found them MUCH easier to breath through than the medium set as my nostrils were being forced wider. The extra size kept them firmly in place and they have not come loose since. The only difficulty is in the initial fitting as the larger size takes some practice to slot into place. Although they are more noticeable when inserted at the entrance of the nostrils they are still far less noticeable than walking around with a face mask on all the time. Once used i then remove them and clean them with an alcohol wipe and store them in the provided carrying case. I keep using the same set until they begin to darken and then i switch to a new set. I have also noticed that if i breath in through my nose and out through my mouth i get less 'runniness' in my nose. It is a real pain having to remove them to blow your nose. All in all i am now happy with them and i will continue to use them - i hope this review has been helpful.
