Nobody likes having pollen or dust allergies, nor do they enjoy suffering through airborne viruses such as colds or the flu. One approach to lessening the likelihood of being bothered by either of these conditions is to wear a mouth and nose mask, but that could get rather awkward and uncomfortable, plus it would make you look kind of funny in some situations. If you're OK with still looking a little funny, however, you might be interested in slapping on a pair of First Defense Nasal Screens – that's right, we're talking nostril filters.

The screens are made from a "100 percent breathable non-latex, skin safe material," and attach around the rim of each nostril via an adhesive that is exposed by peeling off their paper backing. In lab tests, they have reportedly been shown to be over 99 percent effective against airborne allergens, and over 90 percent effective against airborne droplets (such as those that could contain viruses). They are also said to be relatively easy to breathe through.

Needless to say, of course, they still won't do anything to protect against getting viruses through one's mouth or eyes.

The company describes the screens as "virtually invisible," and they pretty much are ... from a certain distance. Up close it's a different story, so you might not want to wear them on job interviews, or when you're asking that special someone if they'd like to accompany you to the movies.

First Defense Nasal Screens are available online, with prices starting at US$9.98 for a pack of seven sets.
