New Technology Reduces Filter
Change-Outs, Lowers Energy Costs,
Improves IAQ

Background:

Poor Indoor Air Quality increases guest complaints about stuffiness,
and odors from cleaning products and other sources.  A survey of
frequent travelers conducted by Opinion Research Corp. and published
in Filtration + Separation (Vol. 42) , indicated that more than 2/3 were
concerned about air quality in US hotel rooms and 42% had
complained to hotel management about air quality conditions.

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 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. The 30/30 is guaranteed to 2.0” w.g.
without media pack failure.

The MERV 8 30/30 is a UL Class 2 or 1 filter, and is available in
configurations suitable to virtually any room air processing unit,
as well as the filter banks used in banquet rooms and casinos.   
Its unique combination of performance, energy savings and
applications flexibility makes it ideal for hospitality environments.

* MERV, Minimum Efficiency Reporting Value, 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 particles.
