The picometre is one thousandth of a nanometre (1/1000 nm), one millionth of a micrometre (also known as a micron)
So, yeah.
If something was that small there would be absolutely no way of filtering out or preventing it from getting in.
But, that’s just an if.
The article doesn’t say what the molecules are they used. So to speculate on the product of it’s decomposition is not really productive. But, the statement that it (impossibly) leaves no trace is absolutely false.
