15 x 7% = 105% Obviously that's not how those numbers work, but you get the idea: it's not necessary to filter all the air at once.

- ortusdux 6y agoI rounded up to be generous.
- renerthr 6y ago1. I concluded that's what you did, but found it a bit annoying. 100x15/16=93.75 . I find it unnecessarily confusing (as the parent commenter probably did) to round it to 93, when the correct rounding is 94. 2. The article says "15x more", so the right math would be 100x16/17=94.12 .
- ortusdux 6y agoThis is exactly the kind of pedantry I was trying to avoid by rounding. Fan X moves "15x more" air than fan Y. For every 1 unit of air fan X moves, Y will move 1x15 = 15 units. In the time it takes fan Y to move 100 units of air, fan X will move 100*(1/15) units, or 6 2/3rds units. 6.666... rounds to 7.
