Evenflo Baby Bottles How Long Have Evenflo Baby Bottles Been BPA Free?

How long have Evenflo Baby Bottles been BPA free? - evenflo baby bottles

I noticed that all Evenflo bottles in the store are marked as being free of BPA. I have a few bottles of about 8-9 years ago when my son was a baby who has never been used. I would like to take this time, but I do not know whether they contain BPA. I find no information about this .... Does anyone know?
Thank you.
