NOSA nasal menthol plugs are a unique patented design that allows air to pass through a spiral, which significantly reduces odours and masks them with a refreshing menthol scent. Easy to breathe through, NOSA menthol plugs can be used continuously for up to 8 hours, providing effective and long-lasting odour control.
Developed by Susanna Bergstrand a Swedish Nurse in 2016, it is still manufactured in Sweden today.
