The plastic is very sturdy. It's light. I used it on tap water at home and at work and the outcome was the same, delicious. One of the nice things about this product is you don't have to soak the filter. You just fill the bottle up and squeeze it out, twice, and voila! it's ready to drink from. The users' guide says one filter is good for 60 refills. It's really easy to drink from, works just like a regular sports bottle.
