PURAFIL FIRST IN CLEAN AIR
is dedicated to providing superior clean air solutions through the continuous improvement in
people, products and quality systems. Purafil pioneers air quality standards, invests in research and development
and is focused on the engineering and manufacture of innovative, value-added gas-phase air filtration
media, systems and monitoring instrumentation. Recognized as an industry leader, Purafil is
trusted worldwide to protect people, preserve history and improve the reliability of production processes.
THE CHALLENGE
Urbanization and technological advances create adverse
effects in commercial facilities. Poor indoor air quality (IAQ) stems
from automotive exhaust fumes, tobacco smoke, industrial gases
and other sources of outside air pollution.
Used in most commercial buildings, common particulate filters cannot
solve all problems related to poor IAQ. Gaseous contaminants
— not particulate — are the true sources of odor complaints and
can only be controlled through gas-phase air filtration.
THE PURAFIL SOLUTION
At the heart of Purafil’s gas-phase air filtration systems are
small, air-cleaning “pellets.” These pellets remove contaminants
through a process known as chemisorption. During this instantaneous
process, gases are adsorbed, or captured on the surface of
the media.
Unlike adsorption, during chemisorption the contaminants are
chemically transformed into harmless solids that remain trapped
inside the media. Once the gases are removed from your environment,
they cannot re-enter the air stream.
PURAFIL MEDIA HAVE NUMEROUS BENEFITS INCLUDING:
• UL Classification for non-flammability
• Non-toxic and non-hazardous
• Engineered and manufactured
according to strict ISO 9001:2008
guidelines
Purafil manufactures a wide variety of media to remove gaseous and odorous air pollutants from specific
sources. As a single-source manufacturer of media, filters, systems and air monitoring instrumentation, we can
create custom media blends and equipment to meet the unique challenges in your environment. Using a combination
of Purafil media allows you to target multiple contaminants of concern.
We are so dedicated to complete customer satisfaction that we offer a complimentary Media Life Analysis
(MLA) which projects your engineered dry-chemical media’s remaining service life. By performing a comprehensive
analysis of media samples from your air filtration system, Purafil’s in-house laboratory technicians can
project the life cycle of system media and make suggestions to improve system performance.

All media products are not created equal! In fact, most of the imitators don’t even manufacture
gas-phase air filtration products since it’s such a small percentage of their business. At Purafil,
it’s been 100% of our business for 40 years and our expertise has earned us the trust of NASA,
the Sistine Chapel, National Archives & the U.S. Military.

REDUCE OUTSIDE AIR BY 75%
AND IMPROVE AIR QUALITY
An increasing number of commercial buildings are employing energy
conservation products and practices to cut energy costs. Heating, ventilation, and air-conditioning
(HVAC) represents the largest energy use in commercial buildings. Unfortunately,
cutting HVAC costs is often at the expense of indoor air quality (IAQ). History has proven
that buildings with insufficient ventilation compromise the health of building occupants.
Enersave is the solution.

WHAT IS enerSAVE?
Enersave uses ASHRAE Standard 62’s Indoor Air Quality Procedure to cut energy costs
while improving IAQ. Enersave reduces outside air requirements and HVAC loads. How?
By recirculating air that would previously have been exhausted and using Purafil's chemical filtration
systems to keep air clean. Enersave provides substantial operational savings and minimizes upfront
capital costs.
ENERSAVE USES ASHRAE 62: IAQ PROCEDURE
ASHRAE, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers, was one of the first
professional organizations to develop standards relating to IAQ for the well being of human occupants.
1 VENTILATION RATE PROCEDURE
CONTAMINANTS
ASHRAE 62-1981 established the IAQ Procedure, which allowed buildings to reduce outside air requirements
by recirculating air sufficiently cleaned with an air-cleaning system. The procedure was intended to help
buildings conserve energy, while not ignoring the importance of clean indoor air.
Prior to 1981, the standard specified the minimum and recommended outside airflow rates necessary to
provide acceptable IAQ. Known as the Ventilation Rate Procedure (Diagram 1), this procedure is still applied
today. Buildings using this method rely on ventilation air to dilute pollutant levels.
Unlike the Ventilation Rate Procedure, the IAQ Procedure (Diagram 2) does not prescribe
ventilation rates; instead, it allows designers to use “any amount of outdoor air” if IAQ is acceptable to
human occupants.
Though the IAQ Procedure provides a direct solution for controlling pollutants and energy
savings, engineers often default to the Ventilation Rate Procedure because of the complexities
associated with IAQ.
2 IAQ PROCEDURE
In 2002, ASHRAE approved an interpretation that outlines
how to implement the IAQ Procedure in seven
simplified steps. Purafil's Enersave program is based
on these steps and includes the following:
• IAQ modeling
• Documentation
• Chemical filtration
• Ongoing system verification

enerSAVE: THE PURAFIL SOLUTION TO RISING ENERGY PRICES
Enersave allows an engineer or building manager to reduce outdoor air and improve IAQ. Purafil provides superior air
filtration systems along with documentation and ongoing verification reports necessary to comply with ASHRAE 62’s
IAQ Procedure.
USE enerSAVE IN:
EXISTING BUILDINGS
Implement the IAQ Procedure with no additional capital
expenses! Slide out your existing particulate filter
and slide in the Purafilter for particulate and chemical filtration.
For higher levels of gaseous contamination, insert
a 2” or 4” PuraGRID filter in conjunction with your existing
particulate filter. Cut costs even more by reducing the total
demand on heating and cooling equipment. You’ll save
on operational costs, and the reduced demand will extend
the life of your conditioning equipment.
REWORK APPLICATIONS
For buildings undergoing occupancy changes or chiller
redesign due to refrigerant changes, capital expenditures
are often required to handle the increased outside
air demand to meet ASHRAE 62’s Ventilation Rate
requirements. With Enersave, Purafil will replace the
existing particulate filters with Purafilters or insert Pura-
GRIDs, evaluate the building, and provide the calculations
and support necessary to comply with ASHRAE
62’s IAQ Procedure.
NEW CONSTRUCTION
With Enersave, you can reduce overall equipment sizing
for tremendous cost savings on capital
purchases. Purafil offers a broad range of modular systems
to meet your specific airflows, contaminant levels,
and space requirements. Purafil will work with your
construction engineers to assure the optimum balance
of energy savings and proper ventilation required to
handle the increased outside air demand to meet
ASHRAE 62’s Ventilation Rate requirements. With Enersave,
Purafil will replace the existing particulate filters
with Purafilters or insert PuraGRIDs, evaluate the building,
and provide the calculations and support necessary
to comply with ASHRAE 62’s IAQ Procedure.
PURAFIL FILTRATION
In a typical indoor environment there are as many as 100 different chemical contaminants.
ONLY PURAFIL'S UNIQUE AIR FILTRATION TECHNOLOGY
is capable of eliminating these contaminants and reducing their concentration
levels to those prescribed by ASHRAE 62’s IAQ Procedure.
Purafil's air filtration technology is an integral part of Enersave. All of Purafil's systems - from pleated
chemical filters to modular units - combine the power of our patented media formulations with custom

ENERSAVE CASE STUDY:
CENTURY CENTER
THE PROBLEM
Owned and managed by Highwoods Properties, 1800 Century Center is an 18-story commercial office building in Atlanta,
Georgia that faced possible upgrades in excess of $300,000 when a high-occupancy tenant moved into the entire facility.
Constructed in the late 1970s, 1800 Century Center could not provide adequate outside air for the added number of people.
To comply with current codes, including minimum outside air requirements for increased occupancy, Highwoods potentially
had to make the following extensive renovations:
• Adding a new make-up air unit (MUA)
to the roof
• Renovating the building’s structure to
handle the weight of the MUA
• Installing new duct from the basement to
the roof to accommodate more outside air
Highwoods sought a feasible, cost-effective way to avoid purchasing new equipment and restructuring the facility. Engineers
from McKenney’s Mechanical Contractors and Engineers handled the tenant upgrade and brought in Purafil and local representative
Kathy Nix (AirEnergy, Inc.) to help.
PURAFIL PROVIDES THE SOLUTION
Purafil representatives implemented Enersave, an energy-savings program that reduces the need for outside air and still meets
ASHRAE 62-2004’s indoor air quality (IAQ) requirements. Using ASHRAE 62’s IAQ Procedure, Purafil engineers developed an IAQ
model to verify that Enersave would work in Century Center from an environmental standpoint. They recalculated outside air requirements
and accommodated building conditions that existed before the tenant change.
As part of Enersave, Purafil installed two-inch Purafilters ® as pre-filters on every floor’s air handling unit. Each Purafilter ® had a MERV-8 particulate filter and contained
Purafil ® CPS Blend media, a 50/50 volume blend of premium grade activated carbon (Purakol ® media) and sodium permanganate-impregnated alumina (Purafil ®
Chemisorbant media) to remove a broad spectrum of contaminants.
SUCCESSFUL RESULTS
Highwoods Properties was completely satisfied with Enersave, which allowed them to reduce the amount of outside air brought into the building, control gaseous contaminants,
and recirculate clean air. By using Purafil’s energy-savings program, Highwoods saved over $300,000 in capital equipment purchases, and they have continued
to renew their contract for the past ten years!
