The 70% and 99.95% difference is because of the 10x filtration efficiency difference, combined with the CADR difference.
This is very straight-forward.

The "10x" you've been referring to is about the difference in how many particles make it through filters of 99.5% vs 99.95% efficacy [1], not 70% vs 99.95%, which would be 600x [2].
[1] (1−.995)÷(1−.9995)
[2] (1−.7)÷(1−.9995)
"CADR" is a word I included for a reason.
