Tests carried out by an independent laboratory have shown, after only ten minutes of operation, that the EOLIS Manager air purifier eliminates 99.6% of the coronaviruses present in the air.

Both pioneer and expert on indoor air quality issues, NatéoSanté has been involved in the fight against Covid-19 since the beginning of 2020. Moreover, the company was very quickly referenced by the French Healthcare Association as one of the players participating in the national effort to fight the pandemic. It has equipped many hospitals with professional air purifiers in France and abroad, including China.

If the effectiveness of its EOLIS Air Manager models, primarily by health professionals’ choice, was no longer to be demonstrated in the field, conclusive measurements by a French reference level microbiology laboratory, carried out in October 2020 provide additional confirmation of their performance.

Tests carried out with an EOLIS Air Manager 600S as standard

After a series of tests, carried out on a strain of human coronavirus (HCoV-229E) very similar to the SARS-CoV-2 strain, the results show that the EOLIS Air Manager professional air purifier eliminated 99.6% of the coronaviruses present in the test chamber after only 10 minutes of operation.

This 99.6% efficiency was achieved via a standard EOLIS Air Manager 600S equipped with a Perform+ filter unit including a HEPA 13 filter certified according to NF EN ISO 29463-4 (formerly NF EN 1822-4). An aerosol of droplets contaminated with a known concentration of coronavirus was nebulised for five minutes in a hermetically sealed enclosure. The 99.6% abatement rate was then measured after only ten minutes of air treatment at the low speed 2 setting.

The EOLIS Air Manager is effective against the SARS-CoV-2 coronavirus which is responsible for Covid-19

“The results demonstrated by these tests allow us to affirm that our EOLIS Air Manager air purifier is effective in eliminating the SARS-CoV-2 coronavirus, responsible for the Covid-19 pandemic, from the ambient air” adds Anaïs Guyomarc’h, Director of Operations and Research & Development at NatéoSanté.

In fact, “these two strains belong to the same coronavirus family and therefore have very similar structures and dimensions and have comparable airborne transmission mechanisms”.  

” These tests confirm the validity of our technological choices “

Thierry Ricci, director of NatéoSanté

For Thierry Ricci, founder and director of NatéoSanté, “Our policy is to communicate only what we can scientifically prove. NateoSanté attaches great importance to having the performance and safety of its technology evaluated.” He continues: “These successful tests confirm the performance of our professional air purifiers: we have deep experience: we have been experts in indoor air quality for more than ten years. It is the excellence of our work, our technological choices and French-style innovation that are being recognised”.

The professional air purifier to secure enclosed and shared spaces

At a time when the risk of viral transmission by aerosols, in addition to droplets and fomites, is acknowledged, barrier measures, physical distancing, wearing a mask and regular ventilation of enclosed spaces all remain the essential responses to protect oneself individually and collectively. The installation of a professional air purifier completes this health safety system.

In the particular context of a second confinement, which sometimes permits partial or total activity continuation (in companies, in administrations accessible to the public, in schools, colleges or high schools), air purifiers are an additional reassurance of good health.

Germany has addressed the issue for its schools in particular. In France, the Auvergne-Rhône-Alpes Region is considering a plan to equip the private, as well as the public high schools for which it is responsible. In this context, NatéoSanté air purifiers have been selected for a series of tests in high schools.

The EOLIS Air Manager: performance guarantees

The efficacy tests on coronaviruses conducted by NatéoSanté complement all existing performance reports to guarantee the overall effectiveness of the EOLIS Air Manager air purifier:

The Perform+filter units, which are standard equipment on the EOLIS Air Manager, consist of three main components:

  • Bactericidal, virucidal and acaricidal coarse filter – certified to EN 1276 and EN 14675
  • Very high density activated carbon filter (THD)
  • Medical grade HEPA H13 filter – certified EN 1822-4

The combination of these filters with other innovative technologies, such as germicidal UV-C lamps and the exclusive Active Oxygen function, contributes to the performance of EOLIS Air Manager air purifiers on all indoor air pollutants.

The quality of the HEPA filters used, certified and tested individually to guarantee their filtration performance, is moreover in line with the INRS recommendations issued in October 2020 regarding the precautions to be taken against Covid-19.

In its memorandum, the National Institute for Research and Safety for the Prevention of Accidents at Work and Occupational Diseases (under the aegis of Sécurité Sociale) writes of air purifiers: “Only devices equipped with universal class H13 HEPA filters according to standard 1822-1 can effectively stop aerosols.”

Totally harmless operation as an additional guarantee of safety  

In a study published in 2017, the ANSES (Agence Nationale de Sécurité Sanitaire) also drew attention to the need both to demonstrate the performance of certain air purifiers, but also to ensure that they did not degrade indoor air quality by generating new pollutants.

The EOLIS Air Manager provides an unequivocal answer on this point by incorporating safety. This means that the device purifies the air and, thanks to its eco-design, does not generate or emit any pollutants during operation. This level of safety has been confirmed, with the support of ADEME, within the European Commission run framework of the ETV (Environmental Technology Verification) programme.

Thierry Ricci: from corporate mission to societal commitment

In the spring of 2020, whilst reflecting on the first wave and the efforts made to meet the demand, Thierry Ricci praised his team’s commitment: “This is an illustration of the strength of NatéoSanté’s fundamentals, its history, and its values since its creation: people have always been at the project’s heart! We do things with empathy and integrity. The team takes great pride in fulfilling this mission. Our work takes on ever more meaning!”

At the heart of Covid-19’s second wave, which is overwhelming France, Europe and a huge part of the planet, the 99.6% efficacy now demonstrated against coronaviruses is a recognition and a response to the trust placed in the brand by our customers: the users of our air purifiers.

The results of these tests are a continuation of our daily demand for efficiency and our commitment to our customers”, says Thierry Ricci. Health is a societal imperative. Our response… the drive for better performance”
