Reading will show what I said is correct. It doesn't magically become 20, never was said it did, but it doesn't say ONLY > 50 either. You don't know it isn't also at 20, or what the test was. Another new myth starts based on poor assumptions.
If it was 99% >20u it would have said so. Instead it said 99% >50u.
If it's 99% >50u, then it has to be much less than 99% at >20u.
So please explain how the efficiency vs particle size curve/plot could show otherwise.
Show the graph they made at the 20 mark. You make the claim it's less based on guessing, I make no claim except it isn't known. Show a link to the type of test they used. Already it is assumed to be the USA multi pass test. Context is important, who knows who or what for they put 50 in the video. The efficiency could be 99 >20, flat line at 99, and they chose 50 because the fake filter is so poor it catches zero at 20. Many reasons people do things.
