The Department of Consumer Protection of the Executive Yuan (hereinafter referred to as the DCP) has randomly tested 10 commercially available air purifiers. For quality and safety, all the air purifiers met the requirements during ozone testing. Regarding the labeling check, 4 failed to meet the requirements, and 1 failed to meet the performance claimed on the advertisement used on sales channels. The failed cases have been transferred to the Fair Trade Commission for investigation and punishment. In terms of performance, these air purifiers were tested for their Clean Air Supply Rate (CASR), energy efficiency, and standby power.
Recently, due to heavy air pollution and the COVID-19 pandemic, air purifiers have become very popular products for consumers to fight the pandemic. In order to ensure that suppliers' labeling matches their performance claims and maintain the quality and safety of products purchased by consumers, in May 2020 the DCP randomly tested 10 air purifiers sold at the physical and online stores (7 from physical stores and 3 from online stores). The bases and results of the quality and safety testing, labeling check, and performance testing are as follows:
- Quality and safety testing
- Basis: The testing of the levels of ozone concentrations emitted was conducted in accordance with the National Standard CNS 60335-2-65.
- Results: All 10 air purifiers met the requirements for ozone concentrations.
- Labeling check
- Basis: Commodity Labeling Act and Commodity Inspection Act.
- Results: A total of 4 air purifiers did not meet the requirements. For the violation of the Commodity Inspection Act, suppliers have been asked to correct the defects within a given time limit. In terms of the violation of the Commodity Labeling Act, all defects have been corrected.
- One air purifier failed to mark its commodity specifications in accordance with the Commodity Labeling Act.
- One air purifier failed to mark the name of the manufacturer or the commissioned manufacturer in accordance with the Commodity Labeling Act.
- One air purifier failed to mark the Declaration of the Presence Condition of the Restricted Substances Marking on the commodity's body, box, or instructions in accordance with the Commodity Labeling Act.
- One air purifier failed to meet the Commodity Labeling Act due to the inconsistency between marked and registered voltages.
- Performance testing
- Basis: The testing of CASR, energy efficiency, and standby power was conducted in accordance with the National Standard CNS 16098.
- CASR: The test was carried out in a lab with a height of approximately 2.45m, an internal volume of approximately 28-30m3, at a temperature of 23°C ±3°C, and with a relative humidity of 45% ±5%. The performances from high to low were 7.37cmm, 6.09cmm, 4.68cmm, 4.37cmm, 4.21cmm, 3.65cmm, 3.55cmm, 3.24cmm, and 2.28cmm.
- Energy efficiency: A total of 7 air purifiers met the requirements for the reference value (no less than 0.106cmm/w) of energy efficiency required by the Energy Efficiency Label.
- Standby power: A total of 8 air purifiers met the requirements for the reference values (no more than 1W for those without network function while no more than 2W for those with network function) of standby power required by the Energy Efficiency Label.
