The characters in this book are so incredibly dumb. They say idiotic things, like when the girl is trying to get into the library she's on her phone and someone comes out of their room knocking at the house who they think it is, then proceeds to tell her not to. Just dumb stuff. I couldn't finish reading this...

I've had these filters for about a month. I can notice an improvement in air quality, but no changes regarding our overall health. However, we use the filter everyday, so it's not like we're breathing cleaner air. This isn't to say that there aren't other better ways of providing clean air, though. Still, it seems worth it and we love being able to feel good knowing that we're doing something healthy with our money when using this..

I have tried these before and this batch has a taste of plastic no matter how much you try to cut back. You cannot take them apart to see what is left after each sip. This was the first time ever that i had this problem with an Amazon purchase so it must be some issue. Will not buy these again. Too bad. They were great for about 1 or 2 weeks. Not at all like before. Maybe we are used to. Good Luck!
