1 Requirements of Minimum Energy Performance Standard  and Energy 
Efficiency Rating  Labelling and Inspection for Air cleaners  
Subject：Announcement for the Requirements on Minimum Energy Performance 
Standard and Energy Efficiency Rating Labelling and Inspection of Air 
cleaners  
Basis： Paragraph 4, Article 14 of the Energy Management Act  
Announcement ： 
1. Application Scope：The Air cleaner s refer to in this Announcement are those 
complying with specification as defin ed in CNS 7619 , and as identified by the 
Bureau of Standards, Metrology and Inspection (BSMI) of the Ministry of Economic 
Affairs (MOEA) as products requiring inspection before marketing. 
2. Test Method ：Complying with  CNS 7619 
3. Minimum Energy Performance Standard (MEPS)： 
(1) The measured value of energy  efficiency  CADR/W (Dust) (cmm/W) rounded 
off to the third decimal place shall not be lower than the MEPS for a ir cleaner s 
set forth in Table 1  and shall be greater than 95% of the declared  value on 
products.  Both criteria must be met.  
(2) The measured  value of standby power (W) rounded off to the second decimal 
place shall not be greater than the MEPS for a ir cleaner s set forth in Table 1 
and the declared value on products.  Both criteria must be met.  
4. Labe lling S cheme for Energy Efficiency Rating 
(1) Minimum size of displayed l abel：140mm (height)× 100mm(width), sample and 
specification are as followed ： 
       
 2  
      
 
(3) The energy efficiency rating label shal l contain the information  below: 
(i) Name of the product  (Air cleaners ); 
(ii) Model number of the product ; 
(iii) CADR value(cmm);  
(iv) Energy efficiency CADR/W (Dust) (cmm/W); 
(v) Standby power (W); 
(vi) Energy efficiency rating;  
The products shall be classified for energy efficiency rating based on the Energy 
efficiency CADR/W (Dust) (cmm/W) and Standby power (W) as  shown in the 
following Table 2  and shall be marked with the energy efficiency l abel. 
(vii) The year and announcement number of the Announcement containing the criteria 
for energy efficiency r ating of a ir cleaners  used for this rating determination; 
(viii) Registration number for the product; 
(ix) Other text as designated by the Central Competent Author ity. 
(3) Display or post the label 
While manufacturing or importing  air cleaner s, the dealer shall display or attach the 
energy efficiency rating label in /on the product instruction/manual, or place the label in 
a prominent area in  front of the products. While displaying or marketing the products, 
the dealer shall display or post the energ y efficiency rating label in front of the products, 
and shall not hide, destroy or adopt other means to  the label not recognizable by the 
consumers.  
(4) Energy efficiency rating  
The products shall be classified for energy efficiency rating based on the Energy 
efficiency CADR/W (Dust) (cmm/W) and Standby power (W) as shown in the 
following Table 2  and shall be marked on  the energy efficiency rating label.  
 3 After the afo rementioned application is  approved by the Central Competent 
Authority, the dealer can  download the energy efficiency rating label from the 
management system and start using the label.  
(5) Market surveillance  
The number of the sampling and testing products shall be decided based on the total 
selling number of the manufactured or imported air cleaners during the previous year. 
One sample shall be tested out of 3,000 units of such product manufactured or imported. 
If less than 3,000 units were manufactured or imported in the prior year, one sample 
shall still be tested. Nonetheless, the relevant Central Authority may change the 
sampling model or number based on actual needs.

place.  
3. The operating power (W) shall be rounded off to the fourth decimal place.  
4. The standby power (W) shall be rounded off to the second decimal place.  
5. The measured  value of energy efficiency CADR/W (Dust) (cmm/W)  rounded off to the 
third decimal place shall not be lower  than the MEPS for a ir cleaner s set forth  in Table 
1 and shall  be greater  than 95% of the declared value on products. Both criteria must be 
met. 
6. The measured  value of standby power  (W) rounded off to the second decimal place 
shall not be greater  than the MEPS for a ir cleaner s set forth  in Table 1 and the declared 
value on products. Both criteria must be met.
