Institut Pasteur de Lille evaluated the effectiveness of Daikin’s air purifiers against respiratory viruses

Smart buildings can yield considerable value when it comes to supporting a safe and healthy environment, but they must not infringe on building occupants’ rights says Databuild CEO Morag Evans.

According to tests performed in the laboratories of the Institut Pasteur de Lille, Daikin’s air purifiers eliminate more than 99.98% of the human coronavirus HCoV-229E in 2.5 minutes. This virus is of the same family as SARS-CoV-2, the coronavirus causing the COVID-19 pandemic.

As a specialist in air quality management, Daikin sees it as its mission to provide innovative solutions and has been selling air purifiers for over 45 years. Its air purifiers and patented air purifying technology, which is applied in other Daikin equipment, have long since proven their effectiveness against air pollution, as well as seasonal pollen and viruses.

To reinforce the claim of the effectiveness of its technology, Daikin Europe N.V. entrusted the French laboratory Institut Pasteur de Lille with the testing of its range of air purifiers. It has now been formally proven that the Daikin models eliminate more than 99.98% of the human coronavirus HCoV-229E in 2.5 minutes. This is an important achievement.

Institut Pasteur de Lille performed the test with the virus HCoV-229E, which is a coronavirus closely related to SARS-CoV-2. For safety reasons, the SARS-CoV-2 virus itself was not used. The fact that the two viruses are of the same family, is a strong indication that Daikin air purifiers are important weapons to reduce virus transmission risk and help combat the COVID-19 pandemic.

The effectiveness of the Daikin air purifiers is achieved through a combination of the high performance electrostatic HEPA filter, which traps the virus, followed by an intense exposure to Daikin’s patented Flash Streamer technology, which eliminates the virus.

The institute has also tested the air purifiers for effectiveness against H1N1, the virus causing seasonal flu. Under the same test conditions, Institut Pasteur de Lille concludes from its study that the Daikin air purifiers eliminate more than 99.93% of this H1N1 virus in 2.5 minutes. This demonstrates that these units are also very performant in combatting flu.

Air purification and ventilation are key to healthy indoor environments

Daikin air purifiers purify indoor air by circulating it through the unit and letting the air pass a multitude of filters and purifying technologies. Typically the units are used in residential settings, small offices, retail shops, classrooms, medical waiting rooms and doctor cabinets. The airflow of a Daikin air purifier is around 330 m³/hour. This means that the air volume of an average room flows through the unit multiple times per hour.

  1. Olivier Luminati, Project Manager Ventilation and Air Purification, who has worked closely with the Institut Pasteur de Lille on Daikin’s testing project, says: “The test results are great news for society. Just when everybody is preparing for a return to office and normal life, we can create the conditions to do so in a safer way. Daikin’s commitment to healthy indoor environments has resulted in a wide portfolio of air filtration and purification products. We use these technologies in our air conditioning, heating and ventilation solutions, for both small and large building applications. We can basically help anyone with a need for clean and fresh indoor air to find the right solution”.

Indoor air quality has a big influence on people’s performance and well-being. There are many factors that influence air quality, such as PM2.5 particles, allergens, air humidity and so on. Daikin recognized this challenge a long time ago and launched its first air purifier in Japan in 1975. M. Anthony Dimou, General Manager of Daikin’s air purifying business in EMEA: “The obtained results by Institut Pasteur de Lille are a breakthrough for us and society. I am confident that Daikin can become the reference company for indoor air quality management in the EMEA region”.
