O2 Nose Filters with 3M Filtration - Allergy Nose Filter - Nasal Dilators for Sleep, Dust, Pollution & Travel - Anti Snoring Devices - Dust Mask (Size Large, Pack of 20)

Q: How do you know what size to buy?

Image 2 has a sizing chart but the preferred method is definitely buying the trial sizing pack initially to determine fit.

Q: Do these help with perfume?

I never tried the nose filters with perfume but I would be skeptical. They are hard to put in your nose and they block your nose from getting air. I bought them to reduce pollen when I was cutting my lawn. I found myself breathing through my month instead of my nose. They also have a tendency to fall out. Hope this helps

Q: Does it filter the flu virus?

i believe that it might minimize the virus from entering your body. It will definitely help rather than not.

Q: Could these reduce the inhalation of chlorine in swimming pools?

These answers Lolol. I believe the asker is questioning if they will filter chlorine vapors from the air NOT the water. The answer is, it is unlikely. It takes a filter with a smaller micron filtering capability to filter things like vapors in my experience. It might help, but doubtful it would completely eliminate.
