Nasal dilators are devices that are placed in the openings of the nose to widen the air passage and make nasal breathing more comfortable (for people who are using the Knightsbridge without a CPAP machine). Our recommendations are the NasalAid nasal dilator and the light blue Snore Care Set nasal dilators. (NasalAid looks a little intimidating and is a bit more expensive than the others, but it is very comfortable and we feel it is worth the price.)
WARNING: User should be capable of donning and adjusting chin strap themselves.
