ratio", "input power of purification", "standby power" and “minimum
allowable values of energy efficiency” (see Chapter 3; see Chapter 3 of the
2018 edition);
d) The terms and definitions of "clean air delivery rate of particle" and
"purification efficiency of gaseous pollutants" are deleted (see Chapter 3 of
the 2018 edition);
e) The classification method of "Category I products" and "Category II products"
is modified (see 4.1; see Chapter 4 of the 2018 edition);
f) The requirements for energy efficiency ratio and standby power are modified
(see 4.1; see Chapter 4 of the 2018 edition);
g) The requirements for measured and nominal values of energy efficiency ratios
and for energy efficiency grades and nominal grades are added (see 4.2);
h) The test method for "particulate matter clean air delivery rate" is modified (see
6.1.1; see 6.1.1.1 of the 2018 edition);
i) The test method for "gaseous pollutant clean air delivery rate" is added (see
6.1.2);
j) The test method for "purification efficiency of gaseous pollutants" is deleted
(see 6.1.2 of the 2018 edition);
k) The test method for "input power of purification" is modified (see 6.1.3; see
6.1.1.2 of the 2018 edition);
l) The calculation method of the "energy efficiency ratio of gaseous pollutants"
is added (see 6.1.4.2);
m) The test method for "standby power" is modified (see 6.2; see 6.1.3 of the 2018
edition);
n) The implementation requirements for the standard are added (see Chapter 7);
o) Appendix A "Test and calculation method for the purification efficiency of
gaseous pollutants" is deleted (see Appendix A of the 2018 edition).

Minimum allowable values of energy efficiency and energy
efficiency grades for air cleaner
1 Scope
This document specifies the energy efficiency grades, technical requirements, and
testing and calculation methods for air cleaners.
This document applies to.
-- air cleaners with a single-phase rated voltage greater than 5 V and not exceeding
250 V, and other rated voltages not exceeding 480 V;
-- air cleaners with the function of removing particulate matter and gaseous
pollutants;
-- Humidifying purifier and purification fan with independent air purification
function modes.
This document does not apply to.
-- components and modules with air purification functions;
-- wearable air cleaners;
-- duct purification devices and other similar air cleaners;
-- air cleaners designed for industrial use, medical use and vehicles;
-- air cleaners used in special environments with corrosive or explosive gases (such
as dust, steam or methane gas).
2 Normative references
The provisions of the following documents constitute the essential clauses of this
document through normative references in this text. Among them, for referenced
documents with dates, only the versions corresponding to the dates are applicable to
this document; for referenced documents without dates, the latest versions (including
all amendments) are applicable to this document.
GB 12021.9 Minimum allowable values of energy efficiency and energy efficiency
grades for electric fans
GB/T 18801-2022 Air cleaner
GB/T 35758-2017 Household electrical appliances-Measurement of standby power
3 Terms and definitions
The terms and definitions defined in GB/T 18801-2022 and the following apply to this
document.
3.1 air purification function mode(s)
A working mode in which the product only provides a certain removal ability for one
or more target pollutants in indoor air.
3.2 rated condition
The working state corresponding to the air cleaner's nominal maximum purification
capacity.
3.3 off mode(s)
A continuous mode other than standby mode, network mode or active mode when the
air cleaner is connected to the mains power. An indicator that only reminds the user that
the air cleaner is in the off position is included in the category of off mode.
3.4 standby mode(s)
A continuous mode in which the air cleaner provides one or more of the following user-
oriented functions or protection functions when connected to the main power supply.
3.5 network mode(s)
A mode in which the air cleaner is connected to the main power supply and at least one
network function has been started (e.g., restarted via a network command or full
network communication), but the main function has not yet been started.
4 Energy efficiency grades
4.1 The energy efficiency grade of air cleaners is divided into 3 grades, as shown in
Table 1, among which Grade 1 is the highest. The energy efficiency ratio and standby
power measured values of each grade of products shall comply with the provisions of
Table 1.
4.2 The actual measured value of the energy efficiency ratio of the air cleaner shall not
be lower than 90% of the nominal value, and the energy efficiency grade shall not be
lower than the nominal grade.
5 Technical requirements
The minimum allowable values of energy efficiency of air cleaners are Grade 3 of the
energy efficiency grades in Table 1.
6 Test and calculation methods
6.1 Energy efficiency ratio
6.1.1 Particulate matter clean air delivery rate test method
The particulate matter clean air delivery rate test is carried out after the following
conditions are met.
6.1.2 Gaseous pollutant clean air delivery rate test method
The gaseous pollutant clean air delivery rate test is carried out after the following
conditions are met.
6.1.3 Input power of purification
The input power of purification is tested under the following test conditions in
accordance with the method specified in 7.6.1 of GB/T 18801-2022, represented by P,
and the result is rounded to one decimal place. The test conditions shall meet the
following requirements.
6.1.4 Calculation method
6.1.4.1 Calculation method of energy efficiency ratio of particulate matter
The PM energy efficiency ratio is calculated according to formula (1), with the result
rounded to two decimal places.
6.1.4.2 Calculation method of energy efficiency ratio of gaseous pollutants
The energy efficiency ratio of gaseous pollutants is calculated according to formula (2),
and the result is rounded to two decimal places.
6.2 Standby power test method
The standby power is tested under the conditions specified in 6.1.3 and in accordance
with the method specified in GB/T 35758-2017, represented by P0, and the result is
rounded to one decimal place.
7 Implementation of the Standard
For products produced or imported before the implementation date of this document,
implementation will begin 24 months after the implementation date of this document.
