PRESSURE DROP BASICS — TAFF-GUARD FILTRATION
WEB Mar 10, 2020 For filtration purposes, Pressure Drop is the reduction in air pressure caused using a filter. It is a trade-off inherent in filtration: less efficient filters tend to have a lower Pressure Drop; more efficient filters tend to have a higher Pressure Drop.

HOW TO ENSURE A LOW PRESSURE DROP ACROSS A HIGH-MERV FILTER
WEB Apr 24, 2019 A simple rule of thumb for low pressure drop across a high-MERV filter. I’ve shown you data from two MERV-13 filters now. Both are much lower than you’d measure across many of the MERV-13 filters installed in the wild, and I’ve given you the key to achieving similarly low pressure drops.
