1 Requirements on Minimum Energy Performance Standard  and Energy 
Efficiency Rating  Label ling and Inspection  for Air Cleaners  (Draft)  
Subject：Announcement for the Requirements on Minimum Energy Performance 
Standard and Energy Efficiency Rating Labe lling and Inspection of Air 
Cleaners  (Draft)  
Basis： Paragraph 4, Article 14 of the Energy Administration  Act 
Announcement ： 
1. Application Scope ：The Air Cleaners stated in this Announcement refer to  those 
meeting the definition of air cleaners in CNS 16098, and promulgated by the Bureau 
of Standards, Metrology and Inspection (BSMI) of the Ministry of Economic Affairs 
(MOEA) as the products requiring inspection s. However, this Announcement and the 
Requirement s do not apply to air cleaners of the following conditions : 
(1) Both t he rated value and the measured value of cleaning air supply rate (CASR, 
cmm) are either below 0.26 or above 12.80.  
(2) The principle of air purification is merely either  pure ozone, ultraviolet light or 
photocatalyst.  
(3) The product is equipped with USB ports, t he input voltage of t he main body is 
DC 5V , and there is no  power adapter attached ; or the product  accepts only car 
power supply and  is equipped with power supply products for automotive cigar 
lighter ; or the product accepts only three -phase voltage or merely dry cell as the 
power supply.  
2. Test Method ：In accordance  with CNS 16098  
3. The t esting and calculation of Air Cleaners shall comply with the following 
requirements:  
(1) CASR shall be tested in accordance with CNS 16098. The  measured value of 
CASR rounded off to the second decimal place shall be greater than or equal to  
95% of the declared value of products.   
(2) The o perating power  (W) shall be tested in accordance with CNS 16098.  The 
measured value of operating power shall be rounded off to the first decimal place.  
(3) The energy efficiency of Air Cleaners shall be tested and calculated in accordance 
with CNS 16098. The measured value of energy efficiency rounded off to the 
third decimal place shall not be lower than the Minimal Energy Performance 
Standard (MEPS)  of Air Cleaners (see Table 1) , and shall be greater than or equal 
to 95% of the declared value of products.   2 (4) The Standby Power of Air Cleaners shall be tested and calculated in accordance 
with CNS 16098. The measured value of Standby Power rounded off t o the 
second decimal place , and the declared value and the measured value shall not be 
higher than the MEPS  of Air Cleaners (see Table 1) , and the measured value  shall 
not be higher than the declared value of products.   
4. Labe lling Scheme for Energy  Performance and Energy  Efficiency Rating  
(1) The m inimum size of d isplayed label shall be:  140mm (height )100mm(width) .The 
sample s and specification s are provided  as follow : 
       
   
(2) The Energy Efficiency Rating Label shall include  the information  listed as  below : 
(i) Name of the product  (Air Cleaner ); 
(ii) Model number of the product ; 
(iii) CAS R(Dust)  (cmm) ; 
(iv) Energy Efficiency CAS R/W (Dust) (cmm/W);  
(v) Standby Power (W);  
 3 (vi) Energy Efficiency Rating  classified in accordance with  the “Energy Efficiency 
Rating Standard s for Air Cleaners  ” of Table 2 ; 
(vii) The year and  the number  of an nouncement  of the applied  Energy Efficiency 
Rating Standard s for Air Cleaners ; 
(viii) Registration number of the product ; and 
(ix) Other text s designated by the Central Competent Authority.  
(3) The d isplay or post  of the label  
While manufacturing or importing Air Cleaners , the firms  shall display or attach the 
Energy Efficiency Rating Label in /on the product instruction/manual, or place the 
label in a prominent area on the  front of the products.  While displaying or marketing 
the products, the firms shall display , post or disclose  the Energy Efficiency Rating 
Label on the  front of the products.  
(4) Energy Efficiency Rating  
The products shall be classified for Energy Efficiency Rating based on the labeled  
Energy Efficiency CAS R/W (Dust) (cmm/W) and Standby Power , and shall be label ed 
on the Energy Efficiency Rating Label. 
(5) Market Inspection  
The Central Competent Authority may have random inspection per annum while 
applying the inspection of the Energy Efficiency Rating Labeling. The samples for 
random inspection shall be designated by the Central Competent Authority, and shall 
be delivered by  the firms  to the designated inspection laboratories  for testing  within 
the required term. The amount of samples for random inspection  shall be decided 
based on the total amount of products marketed by the manufacturers or the importers 
of the previous yea r. In principle, o ne unit shall be sampled for inspection  for 3,000 
units. If the total amount is less than 3,000 units, one unit shall still be sampled for 
inspection . Nonetheless, the Central Competent Authority  may adjust  the sampling 
ratio for random i nspection  according to  actual needs.
