Reviews
“After wearing the O2 Nose Filters for eight hours in the city they are a dark grey. I can see they work and feel my breathing in the evening is considerably lighter than before I started to use them a few months ago.”
“I have my kids wearing the filters as I take them for long strolls in the city and city parks. My son has stopped wheezing now most evenings. For my little girl I feel good knowing it’s precautionary. Thank you!”
“Wearing nose filters has changed the way I live! I have always suffered from Hayfever but have been unable to take any medication due to my profession. I now feel so much more comfortable in nature during the Spring and Summer months and feel much freer and confident to coach.”
“My husband no longer snores at night while wearing the O2 Nose Filters. Not only does he sleep better, but so do I!”
