Review on Berkey Sport Filtered Bottle Portable by James Cross

I bought this to do some filter experiments in my preschool class for our International Space Station Center. but if it really worked out, I'd love to have one for myself! I hate drinking tap water. Now, as for the filtering. the picture says it all. The science teacher washed the containers with the soil samples and I took her gross dirty water (obviously on the left). then I squeezed the bottle and look what happened! I thought it would be a bit cloudy. but now. it was crystal clear!
