Nose clips are all very similar, however, there are some minor differences between most nose clips.
The first big area to notice a difference in is the material they’re made out of. Some nose clips are made with a pliable metal that lets you adjust the size to better fit your nose. Others are made out of silicone, or even a memory plastic, to mold around your nose.
There’s also different kinds of clips and pads where your nose will actually be closed. There’s a growing difference between these, and some people just like other designs more than others. There are soft pads, and there are pads that are textured to help avoid the nose clip slipping off.
While a nose plug is slightly different than a nose clip, their functions are the same. A nose plug inserts into your nostrils while a nose clip clips your nostrils shut.
Nose plugs vary about as much as nose clips do, so it’s important to do your research (for example, reading this guide) before buying anything.
