[9]: 50–52, 59 Standardized testing and certification procedures such as ANSI Z9.5 and ASHRAE 110 can be used, as can qualitative indicators of proper installation and functionality such as inspection of gaskets and hoses. [9]: 59–60 [13]: 14–15
The Facility Guidelines Institute recommends using sequential HEPA filters for ORs with a MERV rating of 7 (i.e., captures particle 10 to 3 μm in size) and 14 (i.e., captures particles from 1 to 0.3 μm in size). [5] One mechanism by which HEPA filters capture particles is electrostatic charge.
The ASHRAE Handbook is the four-volume flagship publication of the nonprofit technical organization ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers [a]). This Handbook is considered the most comprehensive and authoritative repository of practical knowledge on the various topics that form the field of heating ...
Building Enclosure Commissioning (BECx) (sometimes 'envelope' is used instead of 'enclosure') is a quality-focused process wherein the energy performance of a facility, system or assembly is evaluated and verified against defined objectives and criteria.
ASHRAE was founded in 1894 at a meeting of engineers in New York City, formerly headquartered at 345 East 47th Street, and has held an annual meeting since 1895. [4] Until 1954 it was known as the American Society of Heating and Ventilating Engineers (ASHVE); in that year it changed its name to the American Society of Heating and Air-Conditioning Engineers (ASHAE).

In heating, ventilation, and air conditioning (HVAC), testing, adjusting and balancing (TAB) are the three major steps used to achieve proper operation of heating, ventilation, and air conditioning systems. TAB usually refers to commercial building construction and the specialized contractors who employ personnel that perform this service.
Minimum Efficiency Reporting Value, commonly known as MERV, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers to report the effectiveness of air filters in more detail than other ratings.
