M.H.
This is a big concern. This is why we have always used the Playtex drop-in liners, they are garunteed BPA free. I will attach a few sites about it, but they are safe and I would recommend them. I haven't tried the brand you are asking about, but they sound good. My concern with glass bottles is when they get older and throw the bottles aside when finished, I bet replacing them could get pricey. If you heat the bottle in warm water, you should be fine. However, putting in in the dish washer or any sterilizer system then negates that, and if you don't, they aren't getting cleaned completely. I am also going to attach a site about flouride and what water to use to make the bottles. This is interesting and I used filtered city water last time, but not with the next one!
This is also why I NEVER microwave in plastic and steam my veggies in stainless steal cookware. There is a lot out there you have to watch for!
