Room Air Cleaners Key Product Criteria

UL Safety Requirements for Ozone Emitting Models: To certify for ENERGY STAR, measured ozone, per UL 867 Ed. 5.0, shall not exceed 50 parts per billion (ppb).

CADR/Watt Requirement: To certify for ENERGY STAR, the Rated Smoke CADR divided by the operating power consumption measured during the smoke particle removal test (equal to Smoke CADR / Watt) shall be greater than or equal to the Minimum Smoke CADR/Watt Requirement shown in Table 1.

table 1 minimum smoke cadr

*Clean Air Delivery Rate (CADR) must be measured according to the latest ANSI/AHAM AC-1 (AC-1) Standard (Go to www.aham.org for information regarding the latest edition of the AC-1 Standard).

Measured Partial On Mode Power: shall be less than or equal to the Maximum Partial On Mode Requirement as calculated per Equation 1, subject to the following requirements:

i. For a model that has Wi-Fi network connection capability, the model shall have Wi-Fi network connection enabled during testing and a Partial On Mode Network Connected power allowance (PNetwork_Connected)defined in Table 2 shall be applied in Equation 1. These models shall be tested with a properly configured wireless network available and connected to the product when testing. These models will not need to be tested again with Wi-Fi capability disabled.

Partial On Mode Power Allowance

Additional Reporting Requirements:

  1. Report the filter type shipped with the product and the replacement filter model number.
  2. Report the rated and measured CADR for pollen and dust and the measured CADR for smoke per the ANSI/AHAM AC-1-2015 Method of Measuring the Performance of Portable Household Electric Room Air Cleaners.
  3. Report the measured operating power in watts for pollen and dust per the ANSI/AHAM AC-1- 2015 Method of Measuring the Performance of Portable Household Electric Room Air Cleaners.
  4. Report the ozone emissions in parts per billion (ppb) per the UL 867 Ed. 5.0 Electrostatic Air Cleaners.

Optional Connected Criteria:

To be recognized as connected, a room air cleaner shall include the base room air cleaner plus all elements (hardware, software) required to enable communication in response to consumer-authorized energy related commands (not including third-party remote management which may be made available solely at the discretion of the manufacturer).

The specific design and implementation of the connected room air cleaner is at the manufacturer’s discretion provided it is interoperable with other devices via open communications protocol and enables economical, consumer-authorized third-party access to the functionalities provided for in Section 4.4. The capabilities shall be supported through one or more means, as identified in Section 4.2.2. A product that enables economical and direct, on-premises, open standards based interconnection is the preferred option for meeting this requirement, but alternative approaches are also acceptable.

The product must continue to comply with the applicable product safety standards – the addition of the functionality described below shall not override existing safety protections and functions. The appliance must meet manufacturer’s internal minimum performance guidelines, e.g., air cleaning.

Communications

Open Standards – Communication with entities outside the connected room air cleaner that enables connected functionality (Section 4.4) must use, for all communication layers, standards that are:

A. Included in the Smart Electric Power Alliance Catalog of Standards, and/or

B. Included in the NIST Smart Grid framework Tables 4.1 and 4.2, and/or

C. Adopted by the American National Standards Institute (ANSI) or another well-established international standards organization such as the International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), International Telecommunication Union (ITU), Institute of Electrical and Electronics Engineers (IEEE), or Internet Engineering Task Force (IETF).

Communications Hardware Architecture – Communication with entities outside the connected room air cleaner that enables connected functionality (Section 4.4) shall be enabled by any of the following means, according to the manufacturer’s preference:

A. Built-in communication technology

B. Manufacturer-specific external communication module(s) and/or device(s)

C. Open standards-based communication port on the appliance combined with open standards based communications module

D. Open standards-based communication port(s) on the appliance in addition to A, B or C, above

If option B or C is used, the communication module/device(s) must be easy for a consumer to install and shipped with the appliance, provided to the consumer at the time of sale, or provided to the consumer in a reasonable amount of time after the sale.

Open Access

To enable interconnection with the product, in addition to Section 4.2.1 that requires open standards, an interface specification, API or similar documentation shall be made available to interested parties that at a minimum, allows transmission, reception, and interpretation of the following information:

A. Energy Consumption Reporting specified in Section 4.4 (must include accuracy, units, and measurement interval).

Energy Consumption Reporting

In order to enable simple, actionable energy use feedback to consumers and consumer authorized energy use reporting to third-parties, the product shall be capable of transmitting energy consumption data via a communication link to energy management systems and other consumer authorized devices, services, or applications. This data shall be representative of the product’s interval energy consumption. It is recommended that data be reported in watt-hours for intervals of 15 minutes or less, however, representative data may also be reported in alternate units and intervals as specified in the product manufacturer’s interface specification or API detailed in Section 4.3.

The product may also provide energy use feedback to the consumer on the product itself. On-product feedback, if provided, may be in units and format chosen by the manufacturer (e.g., $/month).

Information to Consumers

If additional modules, devices, services, and/or infrastructure are part of the configuration required to activate the product’s communications capabilities, prominent labels, or other forms of consumer notifications with instructions shall be displayed at the point of purchase and in the product literature. These shall provide specific information on what consumers must do to activate these capabilities (e.g. “This product has Wi-Fi capability and requires Internet connectivity and a wireless router to enable interconnection with an Energy Management System, and/or with other external devices, systems or applications.”).

Product Packaging Requirements

In addition to the ENERGY STAR mark, or instead of the ENERGY STAR mark, the ENERGY STAR disclaimer label shall be placed on the product packaging of ENERGY STAR certified air cleaners. The disclaimer logo includes the following statement:

“This product earned the ENERGY STAR label by meeting strict energy efficiency guidelines set by the U.S. EPA. Room air cleaners have demonstrated the potential for improving air quality and providing health benefits. EPA does not endorse manufacturer claims regarding the degree to which a specific product will produce healthier indoor air.”
