Question

This air filter standard uses a most penetrating particle size of 0.3 microns. For 10 points each:
[10e] Name this air filter standard whose performance can be approximated with MERV (“merv”) filters in HVAC (“H-vack”) systems that cannot meet its pressure requirements.
ANSWER: HEPA (“HEH-pah”) filter [or high-efficiency particulate air filter; or high-efficiency particulate absorbing filter; or high-efficiency particulate arrestance filter]
[10h] This air filter is built with a box fan, duct tape, cardboard, and MERV filters. It was designed during the COVID-19 pandemic by the CEO of Tex-Air Filters after he was introduced to a UC Davis Dean’s idea.
ANSWER: Corsi–Rosenthal box [or Corsi–Rosenthal cube, Corsi box, Corsi cube, or Comparetto cube; prompt on CRB or CR box]
[10m] Research done by this chemist at the behest of the U.S. Army Chemical Corps determined the most penetrating particle size used in the HEPA standard. This chemist's work on surface chemistry netted him a 1932 Nobel Prize, and he also names the American Chemistry Society’s journal on surfaces and interfaces.
ANSWER: Irving Langmuir
