* 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 Generates Immediate,
Substantial Energy Savings for Pharma,
According to independent research firm McInvaine Company, “bioclean,” a sector that includes
pharmaceutical manufacturing and biotechnology labs, is the 2nd largest user of high-efficiency air
filtration. Air filters are critical for this industry, both because they are necessary to maintaining standards,
and because they directly impact the largest variable cost item on the balance sheet: ENERGY.
Camfil Farr, a world leader in pre and final filtration products for pharmaceutical manufacturing,
genetic research and biotech, has introduced the first true MERV 8*(ASHRAE 52.2-2007)
“30/30” air filter.
The 30/30® is a high-efficiency radial pleat panel filter engineered specifically to deliver substantial
energy savings in facility air handling units. It has very low initial resistance, and low maintained
resistance, to airflow, and the lowest average pressure drop of any MERV 8 filter. This translates
immediately into energy savings that are both measurable, and significant – typically 15% and higher.
The MERV 8 30/30 filter is distinctive in having earned five stars on the ECI (Energy Cost Index+) –
the best-possible performance ranking. It was designed to deliver the greatest overall value in
medium efficiency filtration.
The Camfil Farr MERV 8 30/30 has a distinctive design that provides full use of the media for
maximum dust holding capacity. Tests show the 30/30 has 30% higher dust holding capacity
than conventional MERV 8 filters. This means a longer service life, and less-frequent change-outs.
The 30/30 has proved highly effective as a system’s filter for a broad range of areas served by
make-up air handling units in pharmaceutical production operations and support spaces.
The media for the 30/30 filter is all-mechanical, rather than electrostatic, and maintains consistent,
high removal efficiency throughout the filter’s life. In contrast, other MERV 8s are made with
electrostatically charged media, whose efficiency plummets as dust loads. (Buyers of electrostatic
media filters are advised to obtain the “discharged MERV” rating, in order to determine the
actual, in-service performance level of the product, to make valid comparisons.)
The Camfil Farr Performance Guarantee Program assures that the 30/30 will maintain its efficiency
over time, and will last longer than any pleated panel filter. It also has very high structural integrity.
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
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.
The MERV 8 30/30 is guaranteed to 2.0” w.g. without media pack failure. It is well-suited to
the higher filter face velocities common in bio-pharma.
The MERV 8 30/30 is a UL Class 2 or 1 filter, and is available in 2” and 4” configurations.
Camfil Farr was awarded “Supplier of the Year” by the ISPE and the 30/30 may be used to meet
Its unique combination of performance, energy savings and applications flexibility makes it ideal
for environments with frequent air changes.
requirements of the U.S. Green Building Council (“LEED”) in terms of efficiency, energy savings
and reduced disposal impact. Detailed data from beta tests of the MERV 8 30/30 at two US
pharmaceutical facilities can be made available to qualified inquirers.
