An inspection shows that several air purifiers sold in Sweden emit excessive levels of the toxic gas ozone. Elsäkerhetsverket and Kemikalieinspektionen tested 20 models, with four exceeding safety limits. Most of the purifiers had some form of deficiency.
A joint inspection by Elsäkerhetsverket and Kemikalieinspektionen has uncovered serious flaws in air purifiers sold in Sweden. Out of 20 models examined, four emit ozone levels above the permitted limits, accounting for 20 percent. "That 20 percent of the inspected air purifiers emitted excessive levels is serious," says Kerstin Gustafsson, inspector at Kemikalieinspektionen, in a press release.
In addition to ozone emissions, deficiencies were found in electrical safety, chemical content, and documentation. Most of the tested purifiers had some issue, and the review confirms that low-price products imported from non-EU countries are more prone to problems.
Ozone is a toxic gas that can irritate airways and eyes, cause coughing and breathing difficulties, and exacerbate asthma. The authorities emphasize the importance of consumers being aware of these risks when purchasing air purifiers to improve indoor air quality.
