CONSUMERS purchasing air purifier machines should be wary about how much ozone such machines produce, the city's quality watchdog said yesterday.
Ozone, which some manufacturers say reduces allergens, is a gas that can cause health problems, including respiratory tract irritation and breathing difficulties.
The Shanghai Quality and Technical Supervision Bureau checked a warehouse of Suning Appliances in Qingpu District yesterday after receiving complaints from some consumers over the strong smell of ozone from home air purifiers they had purchased.
Consumers should make sure their machines meet China's standard of producing no more than 50 parts per billion of ozone. Machines that produce a strong metallic, chemical or fishy smell may not meet the standards.
Many air purifier makers claim their products absorb particles by producing a high amount of ozone to mislead consumers, said Cui Hong, an official of the bureau's patrol team.
He said excessive levels of ozone can lead to a sore throat and skin allergies.
All four air purifiers given quick tests on ozone levels at the Suning store passed. Bureau officials expressed concern that no purifiers made by small producers were available to test. Store officials told the bureau they were sold out.
