“Quantification suggests more than 10^5 particles in each liter of bottled water, the majority of which are nanoplastics”

“nanoplastics are believed to be more toxic since their smaller size renders them much more amenable, compared to microplastics, to enter the human body”

It’s a very low number. Extremely small amount of mass. Probably a complete nothing-burger.

I think humans are pretty ignorant when it comes to how things affect our health, especially when these things are happening at such small scales. 100k every litre ? A litre a day would be 36,500,000 particles a year. What if it accumulates? Not going to discount it 🤔

They got shut down…

Do you know this for sure - their distributor says otherwise.

I received an email saying the filters moved to boroux.com brand.

I thought they did. I hope not. The frivolous complaints about them being pesticides are probably backed by bottled water company lobbyists inside the EPA. We love our berkey.

36M sounds like a big number, but the nanoscale is extremely small so the total mass will be mind-numbingly low. You can easily do the calculation assuming 500 nm particle diameter. V=(4/3)pi r^3 and m = dv are the only equations you’ll need. The density of plastics is about 0.9

How do the nano plastic particles get into water? Is it during manufacture of plastic bottles or just the wall of plastic bottles start to decay and get into the water?
