hey I learned from your blog that filters can help purify your water and that normal drinking water has a lot of stuff i did not know about, there is also a problem for animal life which i didn't know. i found interesting all the things that are in the water we drink. And how Filters can help is pretty cool too. I want to know more about the filters work.
