Coway announced on the 9th that all Virex mattress products have passed safety tests for radioactive substances such as radon and uranium.


The radioactive substance safety test was conducted by KOTITI Testing & Research Institute, a KOLAS-accredited testing organization under the Korea Accreditation Board of the National Institute of Technology and Standards. It confirmed compliance with the legal standards of the Ministry of Environment, the Nuclear Safety and Security Commission, and the Ministry of Food and Drug Safety. KOTITI Testing & Research Institute measures and analyzes radioactive substances that may be contained in manufacturing processes for everyday products.

As a result of this test, all 18 currently sold models, including the ‘Virex Smart Mattress S8+’ and ‘Virex Signature Mattress,’ passed below the radioactive substance standard levels. The products underwent precise testing using a gamma spectrometer (HPGe), verifying safety not only for radon but also for uranium-238 (U-238) series, thorium-238 (Th-238) series, potassium-40 (K-40), iodine, cesium, and other substances.


Coway also operates its own strict safety evaluation tests. Using professional measuring devices approved by the Ministry of Environment, it analyzes radon and thoron emissions from mattress products, materials, and components in sealed chambers, managing them below the standard levels. Additionally, safety regarding gamma ray emissions is secured through portable radiation measuring devices, covering radon and other emissions.


Coway plans to conduct radioactive substance testing and evaluation through external analysis institutions for the entire frame models as well, so consumers can use Virex mattresses with confidence.



A Coway representative stated, “We are strengthening reliability through not only our own tests but also precise verification by nationally accredited testing institutions to ensure consumers can use Virex mattresses without concerns about radon and other radioactive substances. We will do our best to maximize quality competitiveness and customer satisfaction by advancing the safety management system from mattresses to the entire frame products.”
