Myths about Dioxins and Freezing Plastic Water bottles
I have heard that
THESE were good....I heard that Target carried them, as well.
And a friend only uses
Kleen Kanteen stainless steel water bottles - I believe she bought them at our natural (whole foods) store.
"According to the news
the water bottles that you 'are not supposed to
reuse' are numbered 3, 6, or 7 in the recycle triangle. We went through all
of ours & we had none with those numbers.The did have shampoo bottles with
those numbers. I have found the water bottles that the Special K Protein
water comes in to be wonderful! I purchased a bunch of the water at a
scratch & dent grocery store for almost nothing (yeah!). They are heavy
duty & wash well in the dishwasher. They are similar to the Lifewater
bottles, only a little slimmer. "
