The U.S. Environmental Protection Agency (EPA) has created the Environmental Technology
Verification (ETV) Program to facilitate the deployment of innovative or improved
environmental technologies through performance verification and dissemination of information.
The goal of the ETV Program is to further environmental protection by accelerating the
acceptance and use of improved and cost-effective technologies. ETV seeks to achieve this goal
by providing high quality, peer-reviewed data on technology performance to those involved in
the design, distribution, financing, permitting, purchase, and use of environmental technologies.
ETV works with recognized standards and testing organizations; stakeholder groups which
consist of buyers, vendor organizations, permitters, and other interested parties; and with the full
participation of individual technology developers. The program evaluates the performance of
innovative and improved technologies by developing test plans that are responsive to the needs
of stakeholders, conducting field or laboratory tests (as appropriate), collecting and analyzing
data, and preparing peer-reviewed reports. All evaluations are conducted in accordance with
rigorous quality assurance protocols to ensure that data of known and adequate quality are
generated and that the results are defensible.
EPA's National Risk Management Research Laboratory contracted with the Research Triangle
Institute (RTI) to establish a homeland-security-related ETV Program for products that clean
ventilation air. RTI evaluated the performance of ventilation air filters used in building heating,
ventilation, and air-conditioning (HVAC) systems. This verification statement provides a
summary of the test results for the Aeolus Corporation Synthetic Minipleat Panel, SMP-M12-
24244 media air filter.	„ „

VERIFICATION TEST DESCRIPTION
All tests were performed in accordance with RTFs "Test/Quality Assurance Project Plan:
Biological Testing of General Ventilation Filters," which was approved by EPA. Fhe following
tests were performed:
• Bioaerosol filtration efficiency tests of the clean and dust-loaded filter. Fhree bioaerosols
were used in the testing:
o Fhe spore form of the bacteria Bacillus atrophaeus (BG), a gram-positive spore-
forming bacteria elliptically shaped with dimensions of 0.7 to 0.8 by 1 to 1.5 /;m,
o Serralia mcircescens, a rod-shaped gram-negative bacteria with a size of 0.5 to
0.8 by 0.9 to 2.0 /im, and
o Fhe bacterial virus (bacteriophage) MS2 dispersed as a micrometer-sized
poly disperse aerosol.
• Inert aerosol filtration efficiency tests consisting of an American National Standards
Institute (ANSI)/American Society of Heating, Refrigerating and Air-Conditioning
Engineers (ASHRAE) Standard 52.2-1999 (ASHRAE 52.2) type test (0.3 to 10 fimjj and
extended fractional efficiency measurements down to 0.02 |im particle diameter on both
clean and dust-loaded filter.
• ASHRAE 52.2 test providing filtration efficiency results (average of the minimum
composite efficiency) for three size ranges of particles: El, 0.3 to 1.0 /im; E2, 1.0 to 3 .0
/im; and E3, 3.0 /im to 10 /im.
VERIFIED TECHNOLOGY DESCRIPTION
As shown in Figure 1, the Aeolus Corporation
Synthetic Minipleat Panel, SMP-M12-24244
media air filter is a panel filter with nominal
dimensions of 0.61 by 0.61 by 0.10 m (24 by 24 by
4 in.). Fhe filter has a plastic frame, and the filter
media color is white with green stripes. Fhe media
is polypropylene. Fhere are four pleats to the inch
for the media. Fhe Aeolus Corporation part
number is SMP-M12-24244.
VERIFICATION OF PERFORMANCE
Verification testing of the Aeolus Corporation Figure 1. Photograph of the Aeolus Corporati on
Synthetic Minipleat Panel, SMP-M12-24244 media "" Synthetic Minipleat Panel
air filter began on September 9, 2003 at the test SMP-M12-24244 media filter,
facilities of RFI and was completed on October 8,
2003. Fhe results for the bioaerosol filtration efficiency tests are presented in Fable 1 for the
clean and dust-loaded filter. Fable 2 presents the results of the ASHRAE 52.2 test. All tests were
conducted at an air flow of 0.93 m Vsec (1970 cfm).

The quality assurance officer reviewed the test results and the quality control data and concluded
that the data quality objectives given in the approved test/QA plan were attained.
This verification statement addresses two performance measures of media air filters: filtration
efficiency and pressure drop. Users of this technology may wish to consider other performance
parameters such as service life and cost when selecting a media air filter for bioaerosol control.
In accordance with the test/QA plan1, this verification is valid for 3 years following the last
signature added on the verification statement.
