FAQ

As part of our environmental protection initiative, which is inherent to NatéoSanté’s strategy, we wanted to design EOLIS Air Manager professional air purifier in harmony with the principles of sustainable development and for it to comply with these throughout its life cycle.

This includes the choice of materials which we wanted to be emission-free and easily recycled with no additives, paint or glue. By selecting high-quality components, we increase the durability of our products and we refuse to practice planned obsolescence.

Our air purifiers are 100% made in France, in the Loire region, which helps to reduce their carbon footprint. Their low energy consumption, and features such as automatic mode and the planner function, also help to reduce the environmental impact of their use.

In addition, the components of EOLIS Air Manager are all separate to encourage reparability. At the end of the product’s life, each component can be processed in the appropriate specialist processing facility, thus ensuring optimal recycling. We are also working in partnership with Clikeco who recover waste and send the used filters to approved centres. Finally, EOLIS Air Manager has been designed based on the principles of safety.

Eco-design consists of designing and developing products in a responsible manner, seeking to limit the negative impact on the environment as much as possible. To do so, each stage of the product’s life cycle is taken into account: choice of raw materials, national manufacturing, packaging, use, end of life and recovery.

At NatéoSanté, eco-design is one of our core values. We are also the first company to have developed a professional air purifier in this sense. This virtuous way of designing is applied to all our product ranges. As sustainability is at the heart of our corporate culture, we also work daily internally to find solutions to further reduce our environmental footprint.

Safety at NatéoSanté means providing you with effective professional air purifiers that meet your requirements while ensuring that their design and use does not have any negative impact on health or the environment.

There are numerous air purifiers on the market that have not proven their safety. On the contrary, during usage, some can have a negative impact on the indoor air quality, following a sometimes incomplete reduction of the pollutants, resulting in the formation of compounds that are potentially hazardous to health or a release of pollutants associated with improper sealing of the filters.

As an integral part of its social responsibility, NatéoSanté has ensured the complete safety of its devices and has designed them so that they purify the air without emitting any pollutants into the surrounding air (fine particles, VOCs, NOx or ozone).

With this in mind, and supported by the French Environment and Energy Management Agency (ADEME), NateoSanté has had the filtration performance and safety of its EOLIS Air Manager professional air purifiers checked by independent French laboratories. These are currently the only purifiers whose performance and safety has been certified as part of the European Commission’s “ETV” (Environmental Technology Verification) programme for innovative environmental technologies.

An air ioniser generates a large quantity of negative ions within the air in a room which chemically attracts positively charged pollution particles. These particle/ion clusters become heavier and gravity causes them to fall to the ground or cling to nearby surfaces (walls, furniture, etc.). They are sometimes visible to the naked eye as they can darken areas where they are concentrated.

The ioniser helps to reduce the quantity of particles suspended in the air in a room. Their job is not to capture or destroy these particles. They will still be present in the room.

As part of the effort to combat COVID-19, air ionisers will concentrate the droplets or contaminated particles within a limited area of your room which would then become a vehicle of contamination.

NatéoSanté decided to use filtration (in particular HEPA) technologies to collect the particles within its air purifier in a zone away from any potential human contact.

In addition to collecting 99.97% of any particles smaller than 3 µm, our professional air purifiers destroy the organic agents (bacteria, viruses, etc.) by using active oxygen and photocatalysis. Unlike air ionisers, which are ineffective against chemical pollutants such as Volatile Organic Compounds (VOCs), our purifiers capture and destroy them through the high-density activated carbon filter and its active oxygen and photocatalysis technologies.

A HEPA (High-Efficiency Particulate Air) filtration system is used to filter out fine particles. Our medical-grade HEPA air purifier filters are EN 1822 certified and are individually tested to ensure optimum efficiency.

Its cleansing action allows it to work on dust, bacteria, diesel particles, pollen, mould, hair, etc.

HEPA filters are made up of a set of interwoven layers of glass or PTFE fibres, very close together, forming a very fine mesh. The captured particles remain trapped in these fibres and are therefore removed from the indoor air.

The HEPA filter (as well as the ULPA) stops the particles in different ways, depending on their size and behaviour:

• Sieving: This is a firts level filtration, which mechanically blocks the largest particles (>1 micron) on the surface of the filter.
• Interception: This mechanism occurs when a particle (>0.5 micron) follows the airflow of purifier and cannot change direction. It then gets caught in one of the HEPA filter fibres and remains trapped.
• Inertial impaction: Thos occurs for “heavy” particles which, because of their inertia, move in a straight line until they collide with the filter fibres.
• Brownian diffusion: This concerns the finest particles (<0.3 micron), which move rapidly, not in a linear fashion but rather in a zigzag pattern. When these submicron particles pass close to a fibre, they are attracted and then retained by electrostatic forces.

HEPA (High Efficiency Particulate Air) and ULPA (Ultra Low Penetration Air) filters are certified according to the EN 1822-1 April 2019 standard, which defines the classification of absolute air filters into three groups: E (EPA – high efficiency), H (HEPA – very high efficiency) and U (ULPA – very low penetration). These filters are categorised according to their efficiency in retaining the finest and most difficult to capture particles (Most Penetrating Particle Size, MMPS).

The HEPA and ULPA categories are both very effective in capturing pollutants, and in particular fine particles (dust, pollen), from indoor air. Their main difference lies in the size of the particles that these filters will effectively trap between their fibres:

• The HEPA 13 (or H13) filter is effective against 99.95% of fine particles larger than or equal to 0.3 microns,
• For the HEPA 14 (or H14) filter, this efficiency rises to 99.995% for the same size of fine particles,
• Finally, the ULPA 15 (or U15) filter retains at least 99.9995% of particles in the ambient air with a diameter larger than or equal to 0.3 microns.

Our range of air purifiers has been developed in accordance with eco-design values to reduce their environmental impact throughout their life cycle: to purify the air without polluting, that is NatéoSanté’s mission.

The French manufacturing of our solutions is part of this commitment: it also reflects our standards in terms of the quality of our products.

The EOLIS Air Manager indoor air purifier tackles health issues by means of a dual preventive and/or curative action unlike consumer models. The latter are comfort devices that only deal with some of the pollutants, such as larger pollen-type particles.

EOLIS Air Manager is the result of numerous years of Research & Development and multiple patents. It is the most comprehensive device on the market which combines the action of a medical-grade multi-layer filter unit (made in France and each unit inspected) – including a HEPA filter – with the latest UV-C germicidal lamp technologies and a controlled active oxygen distribution function.

NatéoSanté displays complete transparency to its users. The performance is guaranteed through the measurements and data transparency via the interface. The actual wear of the filter is continually checked in accordance with a patented process, as opposed to a simple timer system.

When the filter gets worn, EOLIS Air Manager stops while awaiting a new consumable: that way, it guarantees its ability to effectively purify the indoor air.

A carbon works effectively on VOCs (Volatile Organic Compounds), on gases and on stubborn odours that can be found in our indoor spaces.

Activated carbon beads present in high densities in such filters make it possible to filter out and eliminate:

• bad smells,
• toxic gases,
• formaldehyde,
• benzene,
• hydrogen sulphide,
• ammonia vapours, etc.

UV rays are ultraviolet rays that cannot be detected by the human eye. They are emitted by the sun but only 5% of the rays manage to cross the ozone layer. UV-C rays are a component of ultraviolet rays and are fully absorbed by our atmosphere so they are not naturally present on earth.

UV-C rays are extremely high energy rays, a property that gives them the power to alter biological molecules such as DNA. When bacteria or viruses are exposed to UV-C rays, the structure of their DNA is modified. This modification stops their growth and spread. This is then known as sterilisation.

The sterilisation of a surface depends on the exposure time and the power of the lamps (or LED). If the power of the lamps is sufficient, it takes around 10 seconds to destroy the virus responsible for COVID-19, SARS-CoV-2. The UV-C lamps are used to treat surfaces (operating theatre, public transport, etc.), liquids (stagnant water, etc.) and, of course, air!

In its EOLIS Air Manager air purifiers, NatéoSanté uses lamps with a dominant wavelength of 254 nanometres, thereby ensuring the germicidal/virucidal character. This is not always the case with lamps which have a dominant wavelength of 270 to 280 nanometres.

Photocatalysis occurs through the combined action of the ultraviolet lamp and the oxydation filter.

It eliminates the VOCs (Volatile Organic Compounds) present in glues, varnishes, wall paints, furniture and household cleaning products.

It also eliminates micro-organisms (bacteria, viruses, fungi, spores, mites, etc.) and destroys persistent bad smells (cigarettes, pipes, etc.).

NatéoSanté offers two professional air purifier ranges designed to meet specific requirements:

• EOLIS Air Manager, which responds to health issues,
• Hygeolis, which is aimed at those with odour problems and seeking comfort.

EOLIS Air Manager is the most comprehensive air purifier on the market and boasts numerous features. Equipped with an intelligent air filtration system with its filter unit comprising 4 filters (biocidal pre-filter, HEPA 13 filter, ULPA 15 filter and an extremely high-density activated carbon filter), it effectively combats all sources of air pollution:

• macro-scale particles,
• fine particles and nano-particles,
• bacteria and viruses (99.6% proven effectiveness against coronaviruses),
• bad odours,
• gases, VOCs,
• fine dust,
• micro-organisms, etc.

Hygeolis is the compact professional air purifier which acts in a targeted manner against odour issues in small spaces. A great alternative to synthetic perfume diffusers, the Hygeolis air purifier does not mask odours, instead destroying them by purifying the air naturally, with no risks to people’s health and no environmental impact.

Our EOLIS Air Manager 600 S and 1200 S air purifiers have the Deep Clean 60 min function. This function, which can be turned on and off at will, thoroughly disinfects air in the room, eliminating stubborn odours and micro-organisms in just 60 minutes. This particularly effective method of air treatment must be carried out in an empty room: no humans or animals can be in the room during treatment; only plants and fish may remain.

More about EOLIS Air Manager air purifiers

Several factors affect the air purification time within a room:

• Volume of the room,
• Usage speed of a professional air purifier such as EOLIS Air Manager,
• Positioning of the device in the room. Ideally, the purifier should be installed at the centre of the room. Do not place it near windows, doors or air vents,
• Maintenance of the unit. Filters are replaced according to the manufacturer’s recommendations.

In ideal usage conditions, a purifier such as the EOLIS Air Manager filters approximately 4 times the total air in a 50 m² room in one hour on speed 5. The room’s concentration of particles drops significantly.

As for the concentration of chemical pollutants, the room’s furniture and walls can retain pollutants which they continually release over long periods. Eliminating these pollutants fully therefore takes time.

For the EOLIS Air Manager range of air purifiers, a filter wear indicator shows the level of clogging of your filter unit in real time. When it gets to a 80% level of saturation, a warning message alerts you that you will soon need to replace the filters. When 100% clogged, EOLIS Air Manager stops operating for safety reasons so as to avoid damaging the motor turbine, which would struggle to suck air through totally saturated filters.

As for the Hygeolis air purifier range, a red LED on the front panel flashes when the filter unit needs to be replaced.

To maintain the prefilter, you can carefully remove it from the filter unit using gloves, then gently shake it outside, taking care not to breathe in the pollutants captured by the prefilter. This action will help prolong the life of the pre-filter slightly before it needs replacing.

To replace the filter block, you must follow the following steps:

1 – Turn off your unit,

2 – Open the front cover and remove the filters using the 2 tabs designed for this purpose,

3 – Remove the used prefilter from the filters to replace it with a new one,

4 – Put the filters back in, with tabs facing out,

5 – Close the front cover. Make sure the front cover is positioned correctly, to ensure that your unit will operate correctly,

6 – Turn on the unit. The new filter is tested by the “filter test” system. “New filter?”: You can say NO (only for changing built-in filters).

To replace the filter block, you must follow the following steps:

1. Do not turn off your unit,
2. Open the front cover and remove the filters using the 2 tabs designed for this purpose,
3. Remove the new filters from their packaging, making sure not to damage them,
4. Put the filters back in, with tabs facing out,
5. The message “New filter?” appears: you can press YES. If the front cover is open but you have not changed the filters, you can press NO or ignore the message,

Close the front cover. Make sure the front cover is put in place correctly, to ensure that your unit will operate properly. The new filters are tested by the “filter test” system.

The filter blocks for our air purifier ranges can be purchased on our website, or from your local dealer.

NatéoSanté is committed to a responsible eco-design initiatives in its day-to-day operations: this includes recycling its air purifiers and their consumables.

By surrounding itself with specialist service providers such as Clikeco, NatéoSanté offers you the ability to recycle your filter unit by also implementing a wider collection system for your specific waste (paint, aerosols, batteries, phytosanitary waste, etc.).

The UV-C lamps will wear differently depending on how often you activate the UV-C LAMP (or oxydation) feature. The lifespan for a UV-C lamp is generally 1 to 2 years.

To replace the UV-C lamps, you must follow the following steps:

1. Turn off your unit,
2. Open the front cover and remove the filters to reach the UV-C lamps,
3. To remove or replace a lamp, pull it gently and vertically upwards,
4. Remove the new lamps from their packaging taking care not to damage them and place them in the unit where the old lamps were,
5. Then put the filters back in, with tabs facing out,
6. Close the front cover. Make sure the front cover is positioned correctly, to ensure that your unit will operate correctly. Your EOLIS Air Manager is ready to operate again.

The sensors are located behind the EOLIS Air Manager door. On opening the door, there is a small flap above the filter unit. The VOC and PM2.5 sensors are located behind this flap.

If your unit does not turn off, try to unplug your unit and wait a few minutes before turning it back on. Make sure that Demo Mode is not active (Check in Settings – Demo Mode ON/OFF).

During the pandemic, hydroalcoholic gel and disinfectant products are used more frequently and contribute to increased concentrations of VOCs in the indoor air.

In addition, in certain challenging professional environments (dental practices, podiatry practices, hairdressing salons, etc.), the concentrations are such that the air needs to be treated for several weeks before any real improvement is seen in the air quality. In practice, the floors, furniture and walls can retain pollutants which they then continually release over long periods. During this time, your EOLIS Air Manager air purifier is effective and continues to capture the pollutants to purify your indoor air.

To reduce the time required to decontaminate your environment, make sure the “UV-C lamps” and “active oxygen” features (available on “S” models) are activated and correctly configured. The planner is also extremely useful for maximising decontamination when you are out of the room.

To ensure optimal indoor air purification, we recommend you leave your professional air purifier running at all times. Our models are designed to work 24/7. They are extremely energy efficient.

That said, if you wish to program the operation of your air purifier, EOLIS Air Manager provides you with a planner function for programming the time and operating mode of the device hour by hour and for each day of the week.

Cool air from the ground level is drawn up, filtered, and then propelled out. This can make the air feel cool.

You need to ensure your EOLIS Air Manager model well has the features. UV-C lamps come in models 600, 600 S, 1200, 1200 S. Active oxygen comes in models 600 S and 1200 S.

If the purifier changes fan speed, that means Active Mode is probably on (smart mode), or the planner is programmed with different fan speeds according to days and hours.

If you changed the filer block but EOLIS Air Manager does not detect it, open the front cover to run an immediate filter test. Wait then for the message “Door open. New filter?” and confirm. You can close the front cover. Make sure that the new filters are NatéoSanté certified.

In Active mode, EOLIS Air Manager adapts its operating speed to the level of pollution. If the level of pollution is high, EOLIS Air Manager will go up to maximum speed. However, if the level persists, it will systematically reduce its speed regularly for your acoustic comfort.

If your unit seems to be no longer operating, these are the elements you must check before contacting the maintenance service:

• Check the power plug,
• Make sure the front cover has been closed correctly,
• Your filters may be saturated: make sure the “Pending filter change” message does not appear in “Errors”,
• Make sure the Planner is not set to OFF for a certain amount of time (Settings – Planner ON/OFF).

If none of these actions make your air purifier start again, please contact your distributor/local dealer.

The EOLIS Air Manager air purifier should be positioned in your room so it can optimally purify the surrounding air. It is therefore recommended that you follow these guidelines to ensure effective air filtration:

• Ideally, mount the air purifier on the wall using its wall bracket,
• Do not place the air purifier in sunlight, near a gas-powered appliance or near a heat source (heating, fireplace or stove, etc.),
• Position the air purifier at least 1 metre away from any major sources of pollution (e.g.: fireplaces, aerosols/chemical products, glued floor coverings, etc.) to obtain a representative analysis of the ambient air quality,
• Do not use EOLIS Air Manager in extremely humid or hot environments such as the bathroom, or areas prone to grease, such as the kitchen,
• Place the unit vertically in a stable position on a flat surface. Otherwise, the unit may work poorly or become damaged,
• Place the unit on a dry surface, avoid flammable surfaces or nylon, and radiators or other heat sources,
• Ensure a clear space of at least 50 cm around the air purifier so that the air inlet and outlet are not obstructed or covered,
• Place the air purifier at a height of approximately 1.20 m from the ground to enable the best possible air filtration,
• Ideally, position the air purifier opposite the air vent.

The lifespan of the filters depends on how the unit is used and the concentration of pollutants in the air. For a general use, it will last 8 to 12 months, if the unit operates 24/7. For an instant status of your filters’ conditions, see the real filter wear indicator.

It is sometimes necessary to replace the filter after it has been used for de-pollution after works or prolonged use in an extremely polluted environment (thick smoke, strong persistent odours, etc.). Besides, more frequent replacement may be necessary in professional environments where pollution levels are relatively high (like for hairdressers, chiropodists, dental technicians, etc.).

Do not clean the filter, place it in water or vacuum it: this could cause changes in the fibres or cartridges, leading to poor operation or reduced efficiency of your EOLIS Air Manager. If the alert icon appears on the control screen, a message indicating the advanced use status will appear.

You will receive an alert when your filters are 80% clogged. Depending on the use level of your filters, your unit will alert you as follows:

• 80% used filter: “Plan to change filters”

• 100% used filter: “Purifier OFF – Pending filter change”. If the filter reaches 100% saturation, the unit will stop working.

If the symbol appears, it means an irregularity has been detected by EOLIS Air Manager. Clicking on the symbol will display more details.

Our professional air purifiers are guaranteed for 3 years. You also have the option of paying to extend this warranty for a total period of 4 or 5 years. The warranty will not apply in the event of fire, accidents, theft or bad weather hazards, etc. however. Please see the general terms and conditions of sale for more information about the warranty terms and conditions.

This message appears when you have pressed on the following icons: Night mode, Childproof, On/Off. To activate these features, hold down the icon for 3 seconds.

If this message appears, it means that you previously selected a pin code in the Security setting. Just enter your selected pin code. The list of codes can be found in your device operating manual.

A filter test is carried out every 72 hours of operation (around 3:00 p.m.). When you open the front cover, EOLIS Air Manager conducts a quick filter test to analyse their status of wear.

Your filters are reaching saturation (80%) and must be changed soon (think about ordering filters in advance from your dealer).

Your filters are 100% saturated, and the unit will resume operation once you change the filters.

If the front cover/door of the device is not shut properly, the unit will not operate correctly. Make sure to well close the cover.

When you open the front cover, your air purifier may ask you if you have changed the filter. If so, you can confirm, and if not, press on the cross.

When you open the front cover, EOLIS Air Manager may ask you if you have cleaned the sensors (only if sensor cleaning was required). If so, you can confirm, and if not, press on the cross.

If VOC levels are abnormally high, EOLIS Air Manager will tell you to activate photocatalysis to reduce VOC levels present in the air.

If this message appears in Errors, your air purifier might be too small for your room’s surface area. Also make sure that no exterior doors or windows are open.

When you activate OZONE Mode 2, you must leave the room for 1 hour. Once mode 2 is activated, you have 30 seconds to leave the room.

When you activate OZONE Mode 2, you must leave the room for 1 hour.

If the VOC level is abnormally high, EOLIS Air Manager may be too small for the area of your room. Also check that no exterior doors or windows are open.

If this message appears in the Error category, make sure your unit is plugged in or contact your dealer.

EOLIS Air Manager has detected a high level of pollution. If after 30 minutes, the level of pollution remains, your air purifier will go down to a lower speed to not be too loud, and then will operate at a higher speed again when required by the air quality. Make sure that the doors and windows of your home are closed correctly. Make sure that your device is not too small (placed in a room larger than one it can purify).

This message appears when one or both UV lamps are no longer working. Simply replace the defective lamp(s).

If the filter is missing, put it back in the unit. If the filter is in the unit, please contact your dealer.

The EOLIS Air Manager professional air purifier is the most comprehensive device on the market for indoor air purification. EOLIS Air Manager brings together the most reliable and effective technologies to combat indoor pollution in all its forms. It is the French professional air sanitiser that adapts perfectly to all health situations, even the most complex. It can effectively reduce the airborne spread of viruses, including coronaviruses such as Covid-19, thanks to its unique combination of technologies. This has enabled many professionals to resume working with complete peace of mind while guaranteeing their customers/patients and their team optimum air quality to protect the health of everyone.

The EOLIS Air Manager air purifier from NatéoSanté is 99.6% effective against coronaviruses. This is the result of tests conducted by an independent laboratory specialising in microbiology obtained on a human strain (229E) similar to the SARS-CoV-2 strain responsible for Covid-19.

In ten minutes, the EOLIS Air Manager eliminated 99.6% of the contaminated droplets and destroyed them in a sealed chamber. By extension, these measures can guarantee the effectiveness of the EOLIS Air Manager air purifier against the virus responsible for Covid-19.

Purifying is one of the three pillars of the Aerate – Ventilate – Purify triangle for enjoying the benefits of clean indoor air. Aerating and ventilation are actions that enable you to refresh the air in an enclosed space by reducing CO2 levels.

In turn, EOLIS Air Manager works to purify the air in a room to eliminate all types of pollutants: fine particles, VOCs, micro-organisms and bacteria, etc. It also allows you to guard against the risk of the airborne transmission of viruses.

EOLIS Air Manager is an indispensable addition to the health safety regime. It enables you to guard yourself against the risk of the virus being transmitted via droplets in an open space type enclosed area. That said, droplet transmission is still possible if you are not wearing a mask. That is why NatéoSanté recommends installing EOLIS Air Manager in addition to, and not instead of, barrier measures.

How to protect yourself against transmission of the COVID-19 virus in the air?

In 2016, the NASA published a study demonstrating that air purifiers equipped with HEPA filters could catch nanoparticles with a <0.1 μm diameter. As coronaviruses have a diameter varying between 0.08 and 0.2 μm, HEPA filters are thus efficient against them.

A report published by ANSES (The French Agency for Food, Environmental and Occupational Health & Safety) also proved that HEPA filters could retain most of the droplets masks could not. The EOLIS Air Manager professional air purifier, equipped with a HEPA H13 filter, certified according to the NF EN 1822 standard, is 99.6% effective against coronaviruses.

Viruses and fine particles are captured within the fibres of EOLIS Air Manager HEPA filter. They are then destroyed by the UV-C lamps.

The virus survival time depends on the surface on which it stands. According to a study published by the New England Journal of Medicine in April 2020, on average, the virus would not survive over 3 years. In any case, in the regular using conditions of your NatéoSanté professional air purifier, no pollutant is released into the atmosphere. This criterion has specifically been proven within the European Commission’s “ETV” (Environmental Technology Verification) programme.

EOLIS Air Manager has been developed to avoid any risk of release: the device indicates the filter wear in real time conditions, thanks to its smart interface. This way, when your filters reach the maximum clogging level, the device stops, waiting for a change of filters.
