Small home or not, homes are not sealed environments. A 10x difference is a 10x difference.
Using one small number or produce another small number, so the difference looks small, doesn't hide the 10x change.
- jefftk 4y agoHow is there a 10x change? I see a 0.1% change.
- dan-robertson 4y ago0.90005 times 10 is 9.0005, not 0.9005 (I.e. the two fractions presented are 90.005% and 90.05%). Even if you look at the complement you get 9.995% vs 9.95% which is small. One could imagine that these differences could also arise from eg obstructions to airflow or positioning in the room or the direction of the wind outside. The point is that the difference is dominated by air flow in a typical environment rather than filtering differences.
- infinityio 4y agoIs it a 10x difference? If you used the better filter, you would still have 99.95% of the particles you would have had if you used the worse filter
