>Pressure drop is a measure of the resistance that the air meets as it flows through the respirator filter and into the mask. This is important because the pressure drop affects the comfort and breathability of the mask- specifically a lower pressure drop is desirable as it translates to increased breathability and thus comfort.
> On average, those that have high filtration efficiency are also the ones with the largest pressure drop, which make it difficult to breath.
I'm aware not everyone is wearing a N95 or better respirator, but the metric applies to all masks.
