Information Briefing on:
Sub-micron Filtration for Commercial HVAC Systems
Indoor Air Quality is a Public Health Issue
MERV. Rated Filters
 They are effective on 1 micron and above size particles only.
 MERV. rated filters are not effective on sub-micron size particles.
 Standard HVAC systems allow for 0” to 1” static pressure wc.
 Sub-micron filtration can be achieved through HEPA filtration.
 HEPA ‘s can not be used for standard HVAC equipment due to their very high
static pressure.. 1” to 3” wc.
 MERV. rated filters under the ASHRAE 52.2 standard were designed as a
maintenance item, to keep the heating coil clean.
Hospital Acquired Infections are now the
Sixth Cause of Death in the U.S.
 The Society of Heating, Refrigeration, and Air Conditioning Engineers, ASHRAE,
published their Position Paper, “Airborne Infectious Disease”.
 This groundbreaking document verifies that sub-micron pathogens travel
airborne over very long distances including through HVAC systems, which act
as a mixer.
 They document that, Droplet Nuclei, sub-micron size pathogens including;
Influenza, Measles, Mumps and TB are transmitted airborne. ASHRAE even
provides the mathematical model by which this occurs.
 All inhabited buildings contain 200,000 to 800,000 permanently suspended
sub-micron particles, per liter of air, easily verified with a laser particle counter.
 Every cough or sneeze produces upward of 1 million particles, 200,000 of
these are sub-micron in size, continually re-infecting air space.
An ounce of prevention is
worth a pound of cure
 Public Health must consider the new information we have regarding drug resistant
diseases, pandemics, zoonosis and mutating virus.
 Schools, churches, business’s, shopping centers, truly any building where people
congregate, can contribute to the spread of pathogens from one individual to
another through their HVAC systems.
 Once one family member is infected, the transmission moves from that individual
to others, then to different locations infecting other families, and so on.
 Prevention must be the focal point in Public Health.
Schools: epicenter for the spread of disease
Walter Bischoff of Wake Forest University
discovered that an 8 year-old emitted 20,000 RNA
copies infecting 60+ classmates.
Low MERV Filter Ratings: Many schools have low
MERV rated filters like MERV 4-6. You need a MERV
16 or higher to have any real affect on airborne
viral capture.
No ultraviolet lights: Few schools in the US use
ultraviolet lights. Schools with UV lights have
enjoyed lower airborne viral transmission rates and
higher indoor air quality.
Dry environments: Many schools have 15-25%
relative humidity levels indoors! This is the
PERFECT environment for airborne viral
transmissions and contagions.
Bathrooms with ceiling exhaust fans: Most
bathroom designs do not incorporate floor level
exhaust vents which is the level where most events
occur.
Flu infected children easily infect their
classmates as they all intermingle. Spread is
rampant since child have immature immune
systems.
Schools now have many good reasons to take
a vested interest in advocating for clean and
properly humidified air in the school especially
in the dry wintertime.
Leading virologists Peter Wright1, Gabrielle Neumann2 and
Yoshihiro Kawaoka3 state that flu epidemics start in schools

Air Quality is a Public Health Issue
Adverse affects of dirty air costs $636
per employee per year *
Air affects everybody in your facility
90% of the average person’s time is
spent indoors
 Disease moves through the air
Particulates damage electronics and
machines
Asthma is particulate induced.

Data from Carnegie Mellon School of Architecture
New Technology for Indoor Air Quality
Technology is available for improved air quality
Technology is available to monitor the air
quality
Acting to clean up the indoor air pollution will:
Dramatically improve IAQ
Curb community acquired
infections and hospital acquired
infections
Lower cleaning costs
Limit the destructive power of
dust on indoor equipment
Save money while improving
quality of life
 Establish you as a trend setter in
the IAQ business
Current Status / Trends
 Facilities managers attempting to address this issue are left with choosing UV,
with the high installation and maintenance costs or stand alone HEPA ceiling or
room units that are even more expensive to purchase and maintain.
 HVAC manufacturing companies are attempting to develop new solutions to
address the necessity for preventing the spread of airborne sub-micron size
pathogens through their equipment.
 The Trane Company just introduced a rooftop catalytic oxidization unit to
eradicate airborne pathogens.
Air Filtration, the Logical Solution
 Most professionals suggest air filtration as a logical solution to the issue of
airborne sub-micron pathogens.
 Air filtration uses existing equipment and thereby is relatively inexpensive.
 Air filtration does not add any chemicals or substance that inhabitants
might be allergic or react to.
 Filters have a very low maintenance cost
 The problem has been that MERV. rated filters do not effectively filter submicron particles the size of known pathogens and HEPA cannot be used due
to the high static….. until now.
Containment Filters
 Containment Filters use a very high
voltage static charge to draw submicron particles to the fiber in the
media, allowing fibers to be far apart
creating very low static pressure.
 This feature allows for high initial
sub-micron filtration on every HVAC
system, even low flow P-Tac units.
Containment Filter - Complete System
Containment Filters are manufactured in a variety of
configurations to meet most HVAC requirements. All have low
resistance
 A flat pad, lowest cost, for use at return registers, or in low flow unit
ventilator, P-Tac systems.
 A tapered cube for increased surface area, for roof top units designed for
standard HVAC holding frames.
 Bonnet design for floor dryers or fans.
Custom Configuration includes
 MERV. rated Pre-filter for high dust conditions.
Simple, Cost Effective, Solution
 The issue of airborne particles and pathogens
within facilities is complicated, but can be
addressed.
 The numbers from HAI’s / CAI’s are staggering.
These are unnecessary loss of life and cost to
our medical system.
 Simple, cost effective solutions must be
included by building managers to address these
issues.
 This is a fight we can and must win to address
the spread of airborne transmission of disease.
