IAQ, Turn a Cost Item into
Cash Savings with "30/30"
* MERV, Minimum Efficiency Reporting Value,
+ Energy Cost Index, or “ECI,” is a filter rating
is a number from 1 to 16 that is relative to an
air filter’s efficiency, according to a universal
filtration standard. The higher the MERV, the
more efficient the air filter is at removing
system that looks at the filter’s efficiency over
its lifetime and the energy required to move air
through that filter. ECI compares filters of similar
construction, under the same conditions of
operation and provides an indicator of true
performance. Specifically, the formula is dollars
per percent of filter efficiency. The lower the
value, the better the filter. A filter with an ECI
of five stars maintains its efficiency over its
life and uses less energy to move air through
the filter. It is in the top 20% of all filters
evaluated. A four star filter has a lower
ECI value, and the pattern continues down
to one star, the poorest performers.
MERV 8 Filter Proves Important
New Tool for Reducing Absenteeism,
Cutting Energy Use
According to EPA, 53 million children and 6 million adults spend their days in US schools.
Many school buildings have poor IAQ, which contributes to illness, asthma, and absenteeism.
Notably, asthma is the #1 cause of absenteeism, and one in 13 school children has the disease.
14.7 million school days are missed every year due to asthma, and the number is far higher if
all respiratory illnesses are included. This situation can now be improved through sound
IAQ strategies and the management of environmental “triggers.”
Camfil Farr, a world leader in institutional air filtration, has introduced the first true MERV 8*
(ASHRAE 52.2-2007) “30/30” air filter for schools and similar settings where a healthful
indoor environment is critical.
The 30/30® is a medium-efficiency radial pleat panel filter with 15 pleats per linear foot (2” depth.)
Its distinctive design provides full use of the media for maximum dust holding capacity. Tests
show the 30/30 has 30% higher dust holding capacity than any conventional MERV 8 filter.
This means a longer service life, and less-frequent change-outs. More time between changeouts
translates into less waste – an increasing concern for many districts – and measurable labor savings.
The 30/30 has proved highly effective as a system’s only filter throughout most school
environments, including classrooms, cafeterias, locker rooms, and gymnasiums, and photography
labs. It is also a highly effective pre-filter for configurations that use higher efficiency final filters
such as HEPA or ULPA filters. This is key for schools and universities whose campuses include
laboratory or health care facilities.
The filter media for the 30/30 is mechanical, rather than electrostatic, and was developed using a
patented blend of natural and synthetic fibers. The media maintains consistent, high removal
efficiency throughout the filter’s life. In contrast, other MERV 8s are made with electrostatically
charged media, whose efficiency drops as dust loads. (Buyers of electrostatic media filters are
advised to obtain, in addition to the MERV rating, the “discharged MERV” rating, in order to
determine the actual, in-service performance level of the product, in order to make a
The Camfil Farr Performance Guarantee Program (see “Nation’s Fastest Growing School District
Minimizes Filter Usage” and “University Saves $46,000 annually, not including reduced energy
Costs”) guarantees that the 30/30 will maintain its efficiency over time, and will last longer
than any pleated panel filter.
The radial media pleats on the 30/30 are secured by a welded wire grid, spot-welded on one-inch
centers. The grid is treated for extended corrosion protection and is bonded to the media to prevent
oscillation. A high wet strength beverage board frame creates a stable, non-yielding media pack.
The media pack is bonded to the frame, and diagonal support members are bonded to each pleat
to enhance rigidity through bridge-style engineering. Filter bypass is virtually eliminated, along
with the risk of filter blowouts. The 30/30 is guaranteed to 2.0” w.g. without media pack failure.
The 30/30 was engineered for low initial resistance, and low maintained resistance, to airflow.
It was engineered to have the lowest average pressure drop of any MERV 8. These features
translate directly and immediately into lower energy costs, a major factor for institutional buyers
who consider “life cycle costs,” as well as purchase price, when buying consumable products.
The MERV 8 30/30 filter is distinct in having earned five stars on the ECI (Energy Cost Index+) –
the best-possible performance ranking. It was designed to be the best value in the field for
medium efficiency filtration.
The MERV 8 30/30 is a UL Class 2 or Class 1 filter. Its unique combination of performance and
energy savings makes it ideal for settings that demand frequent air changes, and where student
and teacher absenteeism is an issue.
The MERV 30/30 can play an important role in initiatives such as Green Schools, Sustainable
Buildings and others that seek to minimize energy use, reduce absenteeism caused by airborne
illnesses, and create a healthier environment.
The Camfil Farr 30/30 may be used to meet requirements of the U.S. Green Building Council
(“LEED”) in terms of efficiency, energy savings and reduced disposal impact.
