ENERGY STAR® Program Requirements
for Room Air Cleaners
Partner Commitments
Commitment
The following are the terms of the ENERGY STAR Partnership Agreement as it pertains to the
manufacturing of ENERGY STAR qualified room air cleaners. The ENERGY STAR Partner must adhere
to the following program requirements:
comply with current ENERGY STAR Eligibility Criteria, defining the performance criteria that must
be met for use of the ENERGY STAR certification mark on room air cleaners and specifying the
testing criteria for room air cleaners. EPA may, at its discretion, conduct tests on products that
are referred to as ENERGY STAR qualified. These products may be obtained on the open
market, or voluntarily supplied by Partner at EPA's request;
comply with current ENERGY STAR Identity Guidelines, describing how the ENERGY STAR
labels and name may be used. Partner is responsible for adhering to these guidelines and for
ensuring that its authorized representatives, such as advertising agencies, dealers, and
distributors, are also in compliance;
qualify at least one room air cleaner model as ENERGY STAR within one year of activating the
room air cleaner portion of the agreement. When Partner qualifies the product, it must meet the
specification (e.g., Tier 1 or 2) in effect at that time;
provide clear and consistent labeling of ENERGY STAR qualified room air cleaners. The
ENERGY STAR must be clearly displayed on the top/front of the product, on product packaging, in
product literature (i.e., user manuals, spec sheets, etc.), and on the manufacturer's Internet site
where information about ENERGY STAR qualified models is displayed;
Note: EPA requires the labeling of all ENERGY STAR qualified products according to one or
more of the following options, depending on product design and visibility at both the time of sale
and over the use of the product: on the product; on product packaging; in product literature; and
on the manufacturer's Internet site. The ENERGY STAR has become the national symbol for
energy efficiency, recognized by more than 40% of the American public. As such, the ENERGY
STAR logo should be placed in an area of high visibility, preferably on top/front of the air cleaner
unit, so that the consumer can see that by purchasing and using an ENERGY STAR qualified
room air cleaner, they are helping to reduce air pollution.
provide to EPA, on an annual basis, an updated list of ENERGY STAR qualifying room air
cleaners. Once the Partner submits its first list of ENERGY STAR qualified room air cleaner
models, the Partner will be listed as an ENERGY STAR Partner. Partner must provide annual
updates in order to remain on the list of participating product manufacturers;
provide to EPA, on an annual basis, unit shipment data or other market indicators to assist in
determining the market penetration of ENERGY STAR. Specifically, Partner must submit the total
number of ENERGY STAR qualified room air cleaners shipped (in units by model) or an
equivalent measurement as agreed to in advance by EPA and Partner. Partner is also
encouraged to provide ENERGY STAR qualified unit shipment data segmented by meaningful
ENERGY STAR Program Requirements for Room Air Cleaners -Draft 1

-------
product characteristics (e.g., capacity, size, speed, or other as relevant), total unit shipments for
each model in its product line, and percent of total unit shipments that qualify as ENERGY STAR.
The data for each calendar year should be submitted to EPA, preferably in electronic format, no
later than the following March and may be provided directly from the Partner or through a third
party. The data will be used by EPA only for program evaluation purposes and will be closely
controlled. If requested under the Freedom of Information Act (FOIA), EPA will argue that the
data is exempt. Any information used will be masked by EPA so as to protect the confidentiality of
the Partner;
Note: As noted above, EPA is willing to work through a third party, such as the Association of
Home Appliance Manufacturers (AHAM), to obtain room air cleaner shipment data. This data
may be masked and provided in an aggregate form so as not to be able to identify specific
manufacturer data. This data will not be shared outside of EPA; it is being collected as a tool
to gauge the penetration of ENERGY STAR qualified products in the marketplace.
notify EPA of a change in the designated responsible party or contacts for room air cleaners within
30 days.
Performance for Special Distinction
In order to receive additional recognition and/or support from EPA for its efforts within the
Partnership, the ENERGY STAR Partner may consider the following voluntary measures and should keep
EPA informed on the progress of these efforts:
consider energy efficiency improvements in company facilities and pursue the ENERGY STAR for
buildings;
purchase ENERGY STAR qualified products. Revise the company purchasing or procurement
specifications to include ENERGY STAR. Provide procurement officials' contact information to
EPA for periodic updates and coordination. Circulate general ENERGY STAR qualified product
information to employees for use when purchasing products for their homes;
ensure the power management feature is enabled on all ENERGY STAR qualified monitors in use
in company facilities, particularly upon installation and after service is performed;
provide general information about the ENERGY STAR program to employees whose jobs are
relevant to the development, marketing, sales, and service of current ENERGY STAR qualified
product models;
feature the ENERGY STAR on Partner Web site and in other promotional materials. If
information concerning ENERGY STAR is provided on the Partner Web site as specified by the
ENERGY STAR Web Linking Policy (this document can be found in the Partner Resources
section on the ENERGY STAR Web site at www.enerqvstar.gov). EPA may provide links where
appropriate to the Partner Web site;
provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond the
program requirements listed above. By doing so, EPA may be able to coordinate, communicate,
and/or promote Partner's activities, provide an EPA representative, or include news about the
event in the ENERGY STAR newsletter, on the ENERGY STAR Web pages, etc. The plan may
be as simple as providing a list of planned activities or planned milestones that Partner would like
EPA to be aware of. For example, activities may include: (1) increase the availability of ENERGY
STAR qualified products by converting the entire product line within two years to meet ENERGY
STAR guidelines; (2) demonstrate the economic and environmental benefits of energy efficiency
through special in-store displays twice a year; (3) provide information to users (via the Web site
and user's manual) about energy-saving features and operating characteristics of ENERGY STAR
qualified products, and (4) build awareness of the ENERGY STAR Partnership and brand identity

by collaborating with EPA on one print advertorial and one live press event;
provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase
availability of ENERGY STAR qualified products, and to promote awareness of ENERGY STAR
and its message.

ENERGY STAR Program Requirements
for Room Air Cleaners
Eligibility Criteria
DRAFT 1
Below is the Draft 1 product specification (Version 1.0) for ENERGY STAR qualified room air cleaners. A
product must meet all of the identified criteria if it is to earn the ENERGY STAR.
1) Definitions: Below is a brief description of a room air cleaner and other terms as relevant to ENERGY
STAR.
A.	Room Air Cleaner: An electric cord-connected, portable appliance with the primary function of
removing particulate matter from indoor air. These devices can be further categorized by the
following types of room air cleaner technologies:
1.	Mechanical Air Cleaner: An electrical product consisting of a fan-motor assembly, a filter
media to collect particles, and a housing. Other mechanical air cleaners may include:
I	Electrostatic Air Cleaner: A mechanical air cleaner having a media filter using static
electricity to allow airborne particles to "stick" to the filter.
II	Ionizer: A mechanical air cleaner whose performance is augmented by the inclusion of an
ionizing system that generates a stream of electrons into the air to contact particles. The
electrons generated typically form a cloud or corona and ground airborne particles that
come into contact with it. Ionizing systems, although rare, can also be found supplementing
the performance of precipitators or HEPA air cleaners.
III	High Efficiency Particulate Air (HEPA') Air Cleaner: An air cleaner with a dense media filter
designed to remove 99.97 percent of all airborne particles 0.3|u and larger that come into
contact with the filter. Typically, HEPA filters are added to mechanical or electrostatic air
cleaners, and can be added to an ionizer in special cases.
IV	Ultra Low Penetration Air (ULPA) Air Cleaner: Similar to the HEPA air cleaner, however, the
ULPA filter has a higher density. ULPA air cleaners are designed to trap 99.999 per cent of
all airborne particles 0.12 jli and larger.
2.	Precipitators or Electrostatic or Electronic Precipitator: An air cleaner that typically performs
as both a mechanical air cleaner and ionizer. Typically, within a housing, this product type
employs a fan to draw particles into the unit. The particles are often given a negative charge
as they pass into the unit and are collected onto a positively charged collection plate within
the unit.
3.	Hybrid: An air cleaner embodying one or more of the technologies described above.
4.	Combination Product: An air cleaner that includes a secondary function, other than air
cleaning technology, within the same housing such as a humidifier or dehumidifier.
B.	Airflow: The amount of air volume moved by the air cleaner unit measured in cubic feet per minute
(CFM). Under this Version 1.0 specification, the CFM value must be tied directly to a Clean Air
Delivery Rate (CADR) and measured in accordance with ANSI/AHAM AC-1.
C.	AHAM: Association of Home Appliance Manufacturers.
D.	ANSI Standard C12.10 (multi-part): A series of test protocols recognized by the American National
ENERGY STAR Program Requirements for Room Air Cleaners -Draft 1	4

-------
Standards Institute (ANSI) for measuring the efficiency of a variety of instruments such as watt
meters, watt transducers, power meters, and power analyzers intended to measure the electrical
power consumption of various products.
E.	ANSI/AHAM AC-1-2002: A test protocol for measuring the performance of portable household
electric cord-connected room air cleaners. AC-1 measures the delivery of contaminant free air by
a room air cleaner in cubic feet per minute (CFM). This public standard was developed under the
auspices of AHAM and is recognized by ANSI.
F.	Clean Air Delivery Rate (CADR): Within the scope of ANSI/AHAM AC-1-2002, CADR is defined as
the measure of the delivery of contaminant free air by a household electric, cord-connected room
air cleaner. More technically, CADR represents the rate of contaminant reduction in the test
chamber when the unit is turned on, minus the rate of natural decay when the unit is not running,
times the volume of the test chamber as measured in cubic feet [(RCR - RND) * V], Each type of
contaminant receives a test value which includes: CADR for Dust; CADR for Tobacco Smoke; and
CADR for Pollen. Note: CADR always measures a unit's performance as a complete system and
has no linear relationship to the air movement within the room, or to the characteristics of any
particular filter medium.
G.	Filter Media: Various porous materials used to separate and remove contaminants from the air.
Common filter media range in density from fairly open such as various foams, papers, and felts to
very tight such as HEPA (certified to capture 99.97 percent of particles 0.3|j and larger) and ULPA
(certified to remove 99.999 percent of particles 0.12|j and larger). Occasionally, less tight media
are impregnated with activated carbon to aid in the removal of gases and odors.
H.	Pre-filter: A medium intended to protect finer filters or sensitive air-collection systems from large
airborne contaminants. Pre-filters tend to extend the useful life of the denser media with which
they are often used.
2) Qualifying Products: In order to qualify as ENERGY STAR, a room air cleaner must be covered by one
of the definitions in Section 1A and meet the specification requirements provided in Section 3, below.
For the purposes of this specification, room air cleaners include mechanical air cleaners (e.g.
electrostatic, HEPA, ULPA, ionizers) and precipitators. Combination products and models that do not
rely on a fan to draw contaminants to the unit cannot qualify under this Version 1.0 specification at this
time. EPA may, however, consider including additional product categories in future versions of the
specification based on stakeholder interest.
Note: This Draft 1 specification is based on the ratio of the amount of clean air produced (CADR)
to the amount of electricity consumed by a room air cleaner. EPA is advocating the use of the
ANSI/AHAM AC-1 test procedure to determine the CADR of an air cleaner model. The AC-1 test
is widely accepted by the air cleaner industry as the most effective way to measure the cleaning
ability of the product. A product that cannot provide a CADR reading will not be able to meet this
specification. EPA is interested in learning more about these non-eligible products to determine
how to best measure their cleaning effectiveness.
It is EPA's understanding that while combination products (i.e., an air cleaner with a humidifier or
dehumidifier) are tested by AC-1, their performance is measured without the secondary function
activated. It is important that when purchasing a product that has earned the ENERGY STAR,
the consumer is assured of both the quality and energy efficiency when both functions are
activated. Therefore, at this time, these products will not be eligible for ENERGY STAR under
this specification given the limited data on their energy performance. EPA would like to gauge
manufacturer interest and preliminary thoughts as to how to incorporate these, and other
product types not covered by this Draft in future specification versions.
3) Energy-Efficiency Specifications for Qualifying Products: Only those products covered by Section 2
that meet the criteria provided below may qualify as ENERGY STAR. To determine if a product
ENERGY STAR Program Requirements for Room Air Cleaners -Draft 1	5

-------
qualifies, its CADR must be measured according to the ANSI/AHAM AC-1-2002 test procedure. The
CADR is then divided by the electrical energy consumed in watts; measured according to the protocol
included in Section 4, below. For purposes of this specification, CADR for Tobacco Smoke should be
used when determining the energy efficiency (CADR/watt) of the room air cleaner. Note: An air
cleaner model's tested and measured performance may vary by 1 percent of the minimum CADR/watt
requirement provided below and still be deemed compliant with this specification.
Room air cleaner minimum performance requirement: > 2.0 CADR/watt
Note: The primary objective of ENERGY STAR is to recognize the most energy-efficient products
in the marketplace through the use of the ENERGY STAR label. In developing a specification,
EPA considers the following criteria:
•	Significant energy savings can be realized on a national basis
•	Product performance is maintained or enhanced with increased efficiency
•	Energy-efficient purchase will be cost-effective
•	Energy efficiency can be achieved through several technology options; at least one of
which is non-proprietary
•	Product energy consumption and performance can be measured and verified with testing
•	Labeling would effectively differentiate products and be visible for purchasers
It is not EPA's intention to design a specification that will allow every model to qualify. The
performance level provided in this Draft 1 specification is based on CADR and energy usage data
submitted to EPA by air cleaner manufacturers during the specification development process and
represents approximately the top 25% of this data set. EPA hopes that overtime, the percentage
of qualified products will increase as ENERGY STAR penetrates the market.
EPA has included a 1% tolerance level to account for the natural variations in test instrumentation
and conditions at the time of test measurement. This tolerance would allow products to qualify as
ENERGY STAR as long as the measured performance is at least 1.98 CADR/watt.
EPA's decision to use CADR for Tobacco Smoke in order to calculate the CADR/watt performance
ratio is based on the following items:
1.	CADR pollen readings can be inconsistent. ANSI/AHAM AC-1 recognizes this by allowing
a ±25 margin of error, compared to ±10 for dust and smoke.
2.	After reviewing available product CADR performance data, EPA found similar CADR
values for smoke and dust. It is EPA's understanding that one CADR value would be
closely representative of the other.
3.	The CADR for Tobacco Smoke is recognized by the U.S. Federal Trade Commission as
having a reasonable scientific basis for making high-level performance claims.
Standby Power: EPA is interested in learning more about air cleaner models that continue to
consume energy while in standby mode to support secondary consumer features such as clocks,
remote controls, and other programmable functions. If applicable, EPA will address standby power
associated with room air cleaners in this Version 1.0 specification. At this time, EPA encourages
stakeholders to share their expertise on this subject.
EPA is interested in collecting additional energy consumption data to determine if this
specification level is feasible and justified based on the above criteria. Interested parties
that disagree with the performance level set forth in this Draft 1 specification are
encouraged to provide recommended levels of performance.
4) Test Procedure: Manufacturers are required to perform tests, according to the requirements included
ENERGY STAR Program Requirements for Room Air Cleaners -Draft 1	6

-------
in this Version 1.0 specification, then submit qualifying model information to EPA for approval.
A.	In performing these tests, partner agrees to measure CADR according to the ANSI/AHAM AC-1
Standard. During the ANSI/AHAM AC-1 test, a watt meter or equivalent measuring instrument
shall be used to quantify the energy consumption of the model. The test protocol for measuring
energy consumption of the air cleaner is provided below.
B.	Test results must be reported to EPA using the Room Air Cleaner Qualifying Product Information
(QPI) Form.
Energy Consumption Test Protocol
Purpose: This protocol formalizes the process of testing the electrical energy consumption of room air
cleaners.
Conditions of Test: The test described in this protocol should be conducted under the following
conditions:
Ambient room-temperature: 70° F ± 5°F [21 °C ± 1,5°C]
Relative humidity:	0.4 RH ± 0.05 RH
Electrical frequency:	60 Hertz ± 1 Hertz
Voltage:	120 volts ± 1 volt
Conditioning of Room Air Cleaner Unit Before Test: Testers should assure that the subject unit's motor
is properly broken in by running the unit, without filters, for 48 hours or according to the motor
manufacturer's written instructions.
Testing Instrumentation: Under this Version 1.0 specification, a watt meter, or equivalent measuring
instrument, should be used to measure the total watts consumed. The device must conform to ANSI
Standard C12.10 or the equivalent.
Test Procedure: In accordance with equipment manufacturer's instructions, connect the test
instrument between the power supply and the air cleaner unit under test.
¦	Turn the air cleaner ON with all settings/options (i.e., filter check indicator, fan control, etc.) set on
HIGH. At the same time, be sure that the power-measuring instrument is reset. This step will
ensure capture of the full cycle power consumption.
¦	Adjust the power supply indicator to 120V - 60 Hz.
¦	Let the unit operate for 20 minutes. Record a reading every two minutes. The average of the 10
readings constitutes the electrical energy consumption by the unit. If necessary, convert the
energy measurement into watts, and record wattage consumed.
Note: The current AC-1 test procedure does not include measurement of energy consumption,
although total input watts is measured during the CADR test to ensure the air cleaner is working
properly. With the assistance of Intertek Testing Services (ITS), AHAM's testing laboratory, EPA has
developed a test protocol for measuring energy consumption of a room air cleaner. EPA's intention in
drafting a test protocol is to ensure that this measurement is taken in a consistent manner across all
laboratories and manufacturers. All stakeholders are encouraged to review this test protocol and
provide comments to EPA.
5) Effective Date: The date that manufacturers may begin to qualify products as ENERGY STAR will be
defined as the effective date of the agreement. The ENERGY STAR Room Air Cleaner specification
is effective January 1, 2004.
ENERGY STAR Program Requirements for Room Air Cleaners -Draft 1	7

-------
Note: EPA is interested in obtaining industry feedback on whether or not the effective date provided
above is appropriate. This effective date was chosen to allow manufacturers time to test and qualify
products as ENERGY STAR for a possible product launch at the March 2004 International
Housewares Show. The effective date represents the date in which manufacturers may qualify, label,
and promote air cleaners as ENERGY STAR.
6) Future Specification Revisions: EPA reserves the right to change the specification should
technological and/or market changes affect its usefulness to consumers, industry, or the environment.
In keeping with current policy, revisions to the specification are arrived at through stakeholder
discussions. In the event of a specification revision, please note that ENERGY STAR
qualification is not automatically granted for the life of a product model. To carry the ENERGY
STAR, a product model must meet the ENERGY STAR specification in effect on the model's date of
manufacture. The date of manufacture is specific to each unit and is the date on which a unit is
considered to be completely assembled.
