My step mom said she tried a lot of ways until she started changing out all the bedsheet and towel’s material together with air purifier then my siblings nose got better. They have super sensitive nose and even abit of dust also cannot, they also cannot be near stuffed toys or furry material stuffs. They change bedsheets every 3-4 days, towels and clothings daily.
For blocked nose can try HappyNoz, works pretty well for my LO when she had blocked nose.
