Am I interpreting this correctly that Brita actually works as a limiter for plasticizers in tap water? Specially since tap water plasticizer content can vary by a lot?
If you are interested in water filters that filter out microplastics, look in to filters that have NSF ratings for it. Afaik only the berkefeld filters (NOT berkey) do. Also a lot of water filter companies are sketchy, and market their filters with terms like made from NSF rated components but do not have the actual full filter assemblies tested (red red red flag).
