WHEN YOUR HOME BREATHES, YOU BREATHE EASIER TOO.

WHY INDOOR AIR QUALITY IS IMPORTANT TO YOU.

Consider this, according to the EPA (epa.gov), indoor air quality is five times worse than outdoor
air quality. Most homeowners know that indoor air quality is important, but not all recognize what
contributes to poor indoor air quality, the potential effects and harm, and how to address these
problems. Broan is here to help. For more than 80 years, Broan has led the industry with residential
ventilation solutions that improve indoor air quality and provide healthier home environments.

Moisture that is not

properly ventilated can cause
mildew and mold formation,
which can potentially lead to
structural problems and health
problems. Exhaust ventilation
solutions from Broan remove
humidity at the source to help
maintain the optimal humidity
balance of 40 to 60 percent.

Off-gassing from

construction materials,
carpeting, adhesives and
synthetic materials—as well
as solvents from common
household cleaners—can
accumulate in tightly built
homes. Look to Broan
for continuous ventilation
solutions that meet
ASHRAE 62.2.

Particulates from

dust, allergens, pet dander,
and more can contribute to
poor indoor air quality up to
100 times dirtier than outside
air. With a properly ventilated
home, you create a more
enjoyable, comfortable and
healthier environment.

Cooking effluents

from food preparation can
infiltrate the whole house
in minutes. Grease, oils and
aromas settle permanently
into carpets, furniture, clothing
and other surfaces. Kitchen
ventilation solutions help
eliminate cooking effluents
for a cleaner, more comfortable
and healthier environment.

The original
1932 Motordor

THE UNDISPUTED LEADER IN
INDOOR AIR QUALITY SINCE 1932.

INDUSTRY LEADERSHIP ISN’T A CLAIM.
IT’S EARNED THROUGH INNOVATION.

In southeastern Wisconsin some eight
decades ago, an engineer named Henry Broan

had a revelation: Wouldn't a built-in mechanical
ventilation solution help to provide better indoor
air quality in the kitchen? And so, Motordor
was conceived—the first kitchen ventilator—
and a company was born. Once Mr. Broan had
invented a new category, other applications
were the natural next step. The bath ventilation
fan soon followed, as the passion for improving
indoor air quality continued.

Leadership is built on standards, all to help
ensure the professionalism of an industry. So
in 1957, Broan was among five companies that
founded the Home Ventilating Institute (HVI).
To this day the HVI mark ensures what's stated
on the package is tested and certified for your
confidence. Because Mr. Broan believed that
if you paid good money for something, you
deserved to get what was promised.

Throughout the years, countless innovations
followed, including some of the first certified
ventilation fans and range hoods with efficient
motors and lighting that reduced energy
consumption by as much as 70%. And as homes
were built tighter, Broan was on the leading
edge of whole-house ventilation solutions with
HEPA filtration and energy recovery capabilities.
Today, Broan continues to lead the industry with
efficient and quiet ventilation solutions that are
easier than ever to install.

You see, leadership isn’t about entering a
market, offering a handful of products, and
staking a claim. Leadership is earned and
proven through a passion and commitment
to finding novel solutions to real problems time
and time again. This is exactly why Broan has
taken the job of improving air quality in our
homes very seriously for more than 80 years.

WE INVENTED THE CATEGORY IN 1932. WE HAVE NO INTENTION OF STOPPING.

BROAN KNOWS TODAY’S STRINGENT

VENTILATION CODES AND STANDARDS.

Because today’s homes are built tighter than ever before, what
gets in stays in, unless mechanically ventilated out. Premium
ventilation solutions from Broan dramatically reduce moisture
as well as airborne pollutants from off-gassing building
materials, adhesives and household cleaners. They also help
eliminate allergens, dust, pet dander and cooking effluents—
everything that contributes to poor indoor air quality.

Both spot and whole-house ventilation are important.

Spot ventilation products remove pollutants at the source when
they occur—think bathroom fans and kitchen range hoods—
quickly eliminating humidity, odor and cooking effluents.

Whole-house ventilation, also known as continuous or dwelling
unit ventilation (DUV), continually removes what’s not captured
by spot ventilation for a more healthy and comfortable home.

Understanding today’s ventilation requirements.

The American Society of Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE) set the industry standard
for ventilation and acceptable indoor air quality for low-rise
residential buildings with ASHRAE 62.2. It sets the minimum
standard for spot or local ventilation of individual bathrooms of
50 Cubic Feet per Minute (CFM) delivered airflow at 3.0 sones
or less. It also specifies the requirements for whole-house
ventilation of an entire dwelling at the maximum sound rating
of 1.0 sone for ventilation fans.

Code adoption growing rapidly.

California was a leader in this area with their Title 24 Code.
Other state and city governments are quickly adopting similar
codes such as the International Energy Conservation Code
(IECC) to improve energy efficiency as well as indoor
air quality.

Above-code green building programs such as ENERGY STAR
for Homes, ENERGY STAR
Energy and Environment Design (LEED) Certification Building
Program and the National Association of Home Builders (NAHB)
Green Building Standard are certified green building programs
that promote human health and conserve natural resources.
Let Broan help you meet the goals of these programs.

You’ve come to the right place for product solutions.

With Broan’s extensive product line-up, including exhaust and
balanced ventilation options such as Heat Recovery Ventilators
(HRVs) and Energy Recovery Ventilators (ERVs), you’re sure to
find the ideal solution to meet your needs.

SELECTING THE PROPER WHOLE HOUSE RESIDENTIAL VENTILATION SOLUTION.

Sizing your solution is a factor of square footage and the number of bedrooms in the dwelling to meet
requirements. These charts are based on ASHRAE 62.2. Note that the 2010 and 2013 versions are
different. Most states still operate under 62.2–2010 rates. Before specifying, check local building codes
to ensure it meets requirements.

AN ALTERNATIVE FORMULA APPROACH TO THE TABLES GIVEN ABOVE.

An alternative formula approach to the tables
given above also exists and typically results
in a lower, more precise CFM requirement.
Under the more common 62.2-2010 version,
continuous CFM requirements can be
calculated using a formula as follows.
CFM = .01 x floor area (in square feet) plus

7.5 x (number of bedrooms + 1).

Example: A 3,500 square foot home with
4 bedrooms would require 73 CFM
.01 x 3,500 = 35

7.5 x (4+1) = 38
Add together for a total of 73 CFM
(as compared to the 90 from the above table).

The 62.2-2013 version increases the
multiplier for floor area from .01 to .03. Note
however that infiltration credits can be taken
if blower door testing is conducted.

MOTION & SENSING
TECHNOLOGIES

ULTRA Fans with Sensaire humidity sensing
technology detect the rapid rise in humidity at

to shower humidity much faster than competitive
fans or wall controls. Multi-speed models turn
the fan speed up from the lower continuous
CFM level. Single-speed models turn the fan on
automatically.

ULTRA Fans with motion sensing and multi­speed capabilit y automatically turn the fan up
to maximum speed from the lower continuous
setting when motion is detected which is ideal
for family members who forget to turn the fan on.

QT SERIES QUIET FANS & FAN/LIGHTS

BROAN QT SERIES

SO QUIET, YOU MIGHT EASILY FORGET IT’S ON.

PEACEFUL MOMENTS CAN BE ENJOYED EVEN MORE WITH
VENTILATION FROM A QUIET, QT SERIES FAN. The very quiet Broan QT Series

is the ideal solution for any room that benefits from ventilation. Most QT models operate

at less than one sone—the sound of a quiet running refrigerator. But quiet operation

doesn’t mean less power. Installed properly, the QT Series maintains full-rated airflow in

real-world installations. So choose a QT Series bath fan, fan/light or heater/fan/light for

your application. Broan has the perfect solution for every room.

Broan QT Series™ Bath Fans. A bath fan needn’t call
attention to itself, especially when you don’t want
it to overpower the design of your bath or powder
room. More important, it shouldn’t call attention
to itself when it’s working. So we developed the
QT Series™ to provide very relaxing ventilation.
With an energy efficient option, it simply does its
job quietly, in ever y sense of the word.

A SMART, ECONOMICAL OPTION TO MEET
ASHRAE STANDARD 62.2.

Since most homes have several ventilation fans, Broan SmartSense®
automatically operates your fans to ventilate your home around the clock.
It’s one solution for continuous and spot ventilation requirements.

A SmartSense® system coordinates ventilation fans in various locations to
introduce fresher, healthier air. It may be programmed to ventilate based
on the home’s size, automatically cycling different fans based in the
dwelling based on square footage and the number of bedrooms. LinkLogic
control is at the heart of the system and requires no separate control
wiring. SmartSense® is cost effective as it does require integration with
the home’s air handler, and with only one fan running at a time, it uses
less than 40 watts during ventilation cycles.
