Microplastics are present in all beverages, but those packaged in glass bottles contain more microplastic particles than those in plastic bottles, cartons or cans. This was the surprising finding of a study conducted by the Boulogne-sur-Mer unit of the ANSES Laboratory for Food Safety. The scientists hypothesised that these plastic particles could come from the paint used on bottle caps. Water and wine are less affected than other beverages. These findings have highlighted a source of microplastics in drinks that manufacturers can easily take measures to address.
Does the filtration even catch microplastics?
Presumably some, but the main issue is that tap water does not spend days and weeks in extremely close proximity to plastic immediately prior to consumption.
no it just flows at significant pressure through PVC pipe.
Without data you’re talking out of your hat, and so am I. My recollection is that the data shows that tap water generally has significantly less microplastic content than bottled water. If you care enough one way or another, then look it up and report back.
PVC is for the drains, the sit in PEX (polyethylene) pipes in newer construction/ renovated homes.
I don’t know if PE is ultimately ok, and wouldn’t install it in my house (seems like a burst hazard in 15-20 years), but it’s way safer than PVC.
