First Defense 鼻用スクリーン - サイズ選びと数量パック(1パック、S)

I was skeptical to use these, I saw them on an old shark tank episode, & i do suffer allergies, & have animals. So when I wake up in the morning in stuffy,then running nose,watery eyes etc,,, I tried these nasal screens & they made a huge difference in my sleep & when I woke up. No stuffy,running nose. They stay on securely & easy to use. I would definitely recommend them .

These nasal filters are great! As someone who suffers from allergies, I keep these in my purse ready for cleaning, yard work, or any project that puts me into contact with an allergen.. They are easy to put on, discreet and convenient to carry around! They also stay in place perfectly until I remove them. They claim that these help 'alleviate respiratory suffering by comfortably filtering inhaled air and removing airborne germs, allergens and/or noxious particles'- knowing that makes me feel better to use these when viruses are going around and during flu season.. the only issue I ever had with these was when i accidentally ordered the small size. I think they are for a child and it restricted my air flow.. but the medium & large seem to fit great and work perfectly. A wonderful article I read (g16, No.6) gave some great precautions to take to prevent spread of diseases. It mentioned these suggestions below... 'Do not share personal items, such as razors, toothbrushes, or towels.... And do not underestimate the benefits of washing your hands thoroughly and frequently. It is perhaps the most effective way you can stop the spread of infection. If possible, stay home when you are sick... cough or sneeze into a tissue or your sleeve, but not into your hands. An ancient proverb states: “The shrewd one sees the danger and conceals himself.” (Proverbs 22:3) How true are those words today in a world plagued with potentially dangerous diseases! So inform yourself by consulting local health services, and conceal yourself from danger by practicing good hygiene. Bolster your defenses, and reduce the risk of disease!' UPDATE: Even though the smaller size fits my nostrils I've found that only the large size allows for me to breathe better.. so I ordered the larger size

Bought to use for yard work and construction work. Went on easy, no skin irritation. However, it did restrict airflow through the nose and I had to fight the urge to mouth-breathe. Only lasted until I had to blow my nose, so I might try next the clip on ones that are reusable with pop-in filter.

size fits good, good air flow and stays stuck for long time

I found that wearing the screen made breathing strained and I took them off. Also, they were very visible which was unacceptable.
