Common questions

Can I boil PFAS out of water?

No. Boiling does not remove PFAS and can concentrate contaminants as water evaporates.

Does bottled water avoid PFAS?

Not always. Bottled water quality depends on the source and treatment, so check the brand's testing information if PFAS is the reason for switching.
