* 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.
New Technology Reduces Filter Change-Outs,
Lowers Energy Costs, Improves IAQ
Poor Indoor Air Quality increases guest complaints about stuffiness, and odors from cleaning products
Poor IAQ also reduces productivity and increases absenteeism. Now, new air filter technology

addresses these issues. Equally important: this new filter substantially reduces energy costs,
and extends the time between changeouts. One location of a 445-property hotel corporation
converted to Camfil Farr’s filter, and the location’s number of air filters needed per year went
from 8400 to 1680.
Camfil Farr, a world leader in filtration products for the hospitality industry, 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 to produce substantial energy
savings for hotels, restaurants, casinos and other facilities. In the example referenced above,
the hotel reduced its energy costs per room by 17% – a huge savings by any standard.
The 30/30 has very low initial resistance, low maintained resistance to airflow, and the lowest
average pressure drop of any MERV 8 filter. The MERV 8 30/30 filter has earned five stars on the
ECI (Energy Cost Index+) – the best-possible performance ranking. The 30/30 technology earned
the 700-room hotel the chain’s energy award for their proactive efforts in significantly reducing
energy consumption and costs.
The MERV 8 30/30 was designed to deliver the greatest overall value in medium efficiency filtration.
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 conventional MERV 8 filters. This means a
longer service life, less-frequent change-outs and a reduction in waste management burdens and
inventory expense. It also reduces the labor required for filter replacement.
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 should obtain the “discharged MERV” rating, in order to determine the actual
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 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 30/30
is guaranteed to 2.0” w.g. without media pack failure.
