This thing does exactly as advertised and works like a champ sucking snot out of my germ infested kids noses'. Ive been using it for 4 years on 3 different kids. Today is the last. It seems physically impossible for it not to atomize mucus and drive it down to the bottom of your lungs. I get sick every time i have to use it on my sick kids. You can say "oh its just cause you were around your sick kid." BS my friends. I catch it....my wife doesnt. She doesnt suck the boogies. I do. She did it once and got sick. Never again for her but I take it in the lips because I would rather my child be able to breathe and it gets those boogies! But IM DONE Nosefrida! Come up with a legit filter!!!! Anyway....take my advice. If you buy this find a way to filter better than what is included or pay! Good luck.
