Air conditioning systems, fans? No! Air cleaners!
Which devices really provide protection from virulent accumulations of aerosol in the room air?
Do fans or air conditioners enhance the distribution of droplets and aerosols in the room?
Not only in times of Corona, dangerous superficial knowledge, untruths and recommendations about air conditioners and air cleaners spread like a wildfire in social media. Air conditioners are blamed to be virus spreaders. And simple fans are hyped to provide protection from infectious aerosols in the air. No matter whether the window is open or closed. What is right? What do you need to know about air conditioners and fans with regard to Corona virus?
How are room air and the Corona virus linked with each other?
Virologists agree with each other: The Corona virus mainly spreads by breathing, only a small amount is distributed by smear and droplet infections. When breathing through the mouth and when talking, thousands of aerosols – tiniest particles of saliva – are emitted into the room.
These particles are invisible to the naked eye. They spread further than the recommended minimum distance of 1.5 - 2.0 m, remaining in the room air for several hours. If a person is infected, these floating particles are contaminated with viruses or bacteria. If infectious aerosols are inhaled, viruses deeply penetrate the pulmonary alveoli via the respiratory tract.
Respiratory masks with particle filter offer protection from aerosols in closed rooms, as well as high-frequency air cleaners as the TAC V+ from Trotec. However, protective masks do not protect from inhaling infectious aerosols. They only keep away large droplets.
Are inside and outside air equally dangerous?
Outdoors, aerosols emitted when talking are distributed and diluted by natural air movements. For this reason, the risk of inhaling other people’s aerosols when they talk is relatively small. However, in closed rooms with no air exchange, the concentration of aerosols increases with every additional person. Undiluted accumulations of aerosols float throughout the room, and the danger of inhaling infectious viruses from the air is comparatively high.
How does an air conditioning system affect the danger of infection?
Air recirculation devices only cool down the room air, but there is no fresh air supply from outside. Besides, commercially available air conditioning systems are not equipped with a special HEPA filter – which is part of the air cleaner TAC V+ or TES 200 with H14 HEPA filter that allows to filter airborne viruses or bacteria. Present viruses in the room air are extensively distributed in the room air with the air flow. This is why “virus spreader” is a word.
- Air conditioning systems with air recirculation do not offer protection against viruses such as the Corona or influenza virus. Accumulations of aerosol are not diluted or filtered out.
- Aerosols carrying viruses are distributed through the blown-out air of the air conditioning system into the farthest corner of the house. Even if you stick to the distancing regulations, you'll inhale the aerosols.
Does a fan protect from an infection if the window is open?
Some virologists recommend placing a fan in front of the open window to transport the germ-laden room air to the outside.
In theory, this is right. The air current produced by the fan sucks in room air and blows viruses out of the window. In practice, however, this is quite unrealistic! In summer, an open window with the fan switched on may be quite pleasant.
But what do you do in winter, when it's freezing outside with temperatures below zero? And how are you able to concentrate on your work in the office, if traffic noise booms through the open window? In retirement homes and treatment centres, it cannot be recommended either. Elderly people in retirement homes have an increased need for warmth. An open window may have severe consequences.
- Indeed, a fan in front of an open window does reduce the risk of infection. The reason for this is the dilution effect which results from the fresh wind of outside air.
- However, this kind of protection from infection is not quite practical and cannot be realised in the cold season and for older people.
- If the outside temperature is equal to the inside temperature, the outside air cannot flow into the room.
Does a fan protect from an infection if the window is closed?
In closed rooms, a fan provides the same infection protection as an air conditioning system with air recirculation. No protection at all! Without a supply of fresh air from outside, the room air will be merely moved, but not diluted. Moreover, fans don't provide any kind of filtering effect.
- Therefore, a fan in a closed room does not provide protection from Corona virus. Accumulations of aerosol are not diluted or filtered out.
- The opposite is true! Aerosols carrying viruses are distributed through the blown-out air of the fan into the farthest corner of the house. Even if you stick to the distancing regulations, you'll inhale the aerosols.
How reasonable is cross-ventilation in terms of protection against infections?
Cross-ventilation will always allow air changes in the room. The air contaminated with germs is drawn to the outside and fresh air flows into the room. However, airing rooms like this always carries risks. Infectious aerosols always spread through the entire room before they escape to the outside, especially in offices or restaurants where many people stay. All persons remaining in the air current will inevitably inhale these aerosols.
An efficient protection against viruses in the room air can only be provided by a high-frequency air cleaner, such as the TAC V+ that offers HEPA filtration and high air flow rates
The mobile air cleaner TAC V+ purifies room air as effectively as air purification is carried out in hygiene-sensitive hospital operation theatres.
Made possible by the extremely high air flow rate and the innovative H14 HEPA virus filter. The room air is sucked in near the ground, cleaned from bacteria and viruses by means of the HEPA filter and finally released into the room as germ-free air.
Depending on the room size, the room air is circulated and cleaned up to 20 times per hour. The result is that suddenly occurring accumulations of aerosol are diluted with clean air in the area of your head to such an extent that the virus load and risk of infection will be remarkably reduced!
No installation, no complicated connection. Simply plug in and provide for the maximum infection protection possible!

High-frequency air purification protects both personnel and patients
If the room air is kept free from germs and viruses, the airborne risk of infection will be minimised likewise. Trotec high-frequency air cleaners such as the TAC V+ are exactly designed to perform this task for they efficiently and quickly reduce the intensity and time aerosol accumulations and suspended matter stay in closed rooms, creating zones with an extraordinarily reduced risk of infection for both patients and personnel.
Directly at the installation site, the mobile air cleaner TAC V+ creates a “clean zone area”, flooded with purified air and filtered from viruses. Within this zone, the surrounding air nearly completely stays free of airborne germs and viruses because the TAC V+ is able to take in large volumes of contaminated room air and to carry out effective H14 HEPA filtration. Moreover, the device is able to purify room air zones in a flexibly adjustable manner with clean air that has been filtered from viruses and aerosol particles.
Effective against bacteria and virus accumulations
Trotec high-frequency air cleaners are equipped with HEPA filters of class H14 which filter out more than 99.995 % of all fine suspended particles larger than 0.1 µm with a transmittance of only 0.005 %. Or in other words: No more than five of 100,000 particles pass the H14 filter. Thanks to this unique feature, these kinds of high-performance filters are also used in operation theatres or comparable hygienically sensitive areas in order to produce clean air. This way, you create optimum conditions to keep room air and breathing air in waiting and treatment rooms free from germs and viruses in times of spreading epidemics.
Well-known viral strains such as SARS-CoV or MERS-CoV have a particle size of 0.005 to 0.1 µm. Most of the time, they form accumulations with other particles (such as saliva or suspended matter) which increases their size up to 0.4 µm or 0.5 µm. These accumulations are referred to as germs and will be filtered out reliably by the Trotec H14 air cleaning filters.
All H14 HEPA filters by Trotec fulfil the highest quality standards that are obligatory for bacteria and virus filtration.
- Each H14 high-performance filter is tested individually and is assigned its respective serial number
- The test report is enclosed as certificate in duplicate with each H14 filter
- The original test certificate can be filed with the documents for the device. If required, the copy can be attached to the air cleaning device.
- HEPA high-performance H14 filters are tested in compliance with EN 1822 and EN 60335-2-69.
Also suitable for any TAC air cleaner with H13 filter
You can also insert a H14 HEPA filter by Trotec into your TAC air cleaner if you already possess a TAC device. The H14 filters are available as an accessory, e.g. for the professional air cleaners TAC 3000, TAC 5000 or TAC 6500. Simply replace the H13 filter in the filter compartment with a H14 HEPA filter.

Why commercially available HEPA air cleaners are not sufficient for virus filtration in most cases
Large clean air capacity – high-performance filtration – filter decontamination – filter regeneration – noise level in the case of a large air volume – versatility
Well thought out to a detailed level, unparalleled in its entirety: With these 6 plus points, the TAC V+ – as is scientifically proven in several studies – ensures a technically effective and economically attractive solution to reduce the risk of infection by aerosols in closed rooms.
Stable design, flexible installation Virus protection on the spot
Large clean air capacity, high flow pressure and an optimum flow geometry
Only the TAC V+ has "the power to quickly dilute the room air"
Time is the most important factor when it comes to reducing the risk of an indirect infection. And we're talking about the shortest time possible for quickly and effectively diluting the infectious aerosol accumulations that are for example generated by a super-spreader, directly at their source. This requires large volumes of clean air and a high fan performance to establish an optimized flow geometry.
All this is provided by the TAC V+: With a large clean air volume, an optimum flow geometry and a flow pressure that is more than high enough, circulation is established in the room within a very short time, ensuring that all the contaminated room air is diluted and effectively filtered within only a few minutes.
Only circulation rates that are sufficiently high minimize the risk of infection, this is scientifically proven. Where the effective treatment of the risks of infection by aerosol particles is concerned, a high air circulation rate (at least a factor of 6 or even more, if possible) and therefore a large volume of cleaned air are indispensable, despite promises to the contrary made by other providers advertising single to threefold air change rates per hour as sufficient.
As is proven by scientific studies, effective virus filtration requires a sufficiently dimensioned volumetric flow so as to ensure that the air cleaner can provide for the number of air changes required as is guaranteed by the TAC V+. In this context, "air change" does not refer to a complete exchange of the air, but to the proportion of virus-filtered clean air that is supplied, relating to the room volume per hour.
FlowMatic ensures constant air circulation rates even with increasing filter pollution
In order to comply with the circulation rate required by the hygiene concept, a constant volumetric flow throughout the whole operating lifetime is indispensable. However, the filter elements of every air cleaner are successively clogged over time by coarse and fine dust (e.g. caused by traffic load). This leads to an increasing counter-pressure combined with a strongly decreasing air flow rate, inevitably reducing the level of protection envisaged.
With the innovative FlowMatic control of the TAC V+ You no longer have to worry about a decreasing volumetric flow or circulation rates that fall below the values required.
Just like with the cruise control of your car, the FlowMatic sensors capture the actual air flow rate values within the entire filter ladder and consecutively adapt the system performance dynamically. In this way, the air volume target value once preset remains constant in every situation! This not only increases the filter lifetime and system efficiency, but also guarantees compliance with the circulation rate required by the corresponding hygiene concept.
Air cleaners without a FlowMatic control are unlikely to constantly and reliably meet the requirements so as to comply with the circulation rate required.
High-performance filtration: H14 means maximum HEPA filter efficiency
The TAC V+ can "effectively separate" viruses
Exclusively H14-HEPA high-performance filters complying with EN 1822 specifications (ISO 45H filter ISO 29463) like they are used in the TAC V+ are able to even filter the tiny virus-infected aerosol particles (0.1 - 0.2 µm) from the room air, and this at a percentage of 99.995 %. Therefore the filter efficiency of H14 HEPA filters complying with EN 1822 is 10 times higher than that of H13 HEPA filters with 99.95 %, as used in most air cleaners!
99.995 % or 99.95 %? This may not sound like a lot, but exactly these two decimal places make the big difference between H13 and H14 HEPA filters! Virus-carrying aerosol particles are extremely tiny. And "virus filters" are designed to "filter viruses". That's why the TAC V+ not only filters the large, but also the small-sized, highly infectious aerosols from the room air not even filtered out by FFP2 and FFP3 respiratory masks, which therefore don't offer genuine protection. Real safety is exclusively provided by an H14 HEPA filter (EN 1822)!
Scientific studies, however, qualify that a filter performance beneficial to the decay rate pursued can only be confirmed if the volume flow of the air cleaner and the flow speed in the particulate air filter are sufficiently attuned to one another by an adequately dimensioned filter surface, a property which at present cannot be achieved with any other mobile air cleaner than the TAC V+!
Thermal filter decontamination – your safety airbag
Unique technology – Trotec exclusive
 |
Only with the TAC V+ and TES 200 the special, fully encapsulated H14 high-temperature lamellae high-efficiency particulate air filter is treated thermally and heated to approx. 100 °C at regular intervals. Explicitly for this purpose, this filter has been developed and interspersed with special, heat conducting metal fins.
This thermal filter decontamination technology is available exclusively at Trotec and offers you several unique benefits at the same time! By heating the filters, the proteins of the viruses filtered out, which are relevant to the infectiousness, are denatured, and the viruses are practically destroyed. Therefore infectious viruses can no longer enter the ambient air from the filter, for example by improper handling Furthermore, bacteria, germs and other microorganisms are additionally destroyed.
All this means that 100 % employee protection can be ensured during operation and also when the filter is changed! You could say, it's the "virus airbag" that provides for more safety. It is there when you need it – and as long as nothing happens, you won't even notice it.
Scientific studies substantiate the mandatory prerequisite of thermal filter decontamination to ensure effective virus filtration. In fact, Professor Christian Kähler explicitly points out this mandatory provision in his study: "To ensure a maximum degree of hygiene and a longer lifetime in continuous operation, the H14 filter should be heated to approx. 100 °C every day for about 15 minutes, in order to destroy the viruses in the filter and prevent the formation of biofilms, bacteria and fungi without using harmful chemical additives or UV-C radiation."
Thermal filter regeneration – for optimum filter hygiene and a prolonged filter lifetime
No filter humidity, no filter mould or odour, and at the same time a much longer filter lifetime
Aerosol separators and virus air cleaners take effect where many people are present in narrow spaces over a longer time and exhale larger quantities of aerosols. Aerosols, whether virus-carrying or not, for the greater part consist of micro droplets – pure water, that is. Customary H14 filters may be able to "catch" these humid aerosols, however, they also catch additional problems. Since the increasing humidity in the filter causes it to start fouling more quickly. As a result, the filter resistance increases, constantly reducing the clean air volume emitted and thus significantly reducing the filter lifetime. The fast fouling of filters at high loads of aerosols has been scientifically proven by field tests.
Moreover, the constantly high level of humidity favours the formation of filter mould or biofilms. Instead of eliminating a hazard, others may therefore be created. For example, a decreasing flow rate, shorter filter lifetimes and mould on the filter. But since the filter is heated to more than 100 °C at regular intervals, the ingress of moisture, fast sooting and filter mould are not a problem with the TAC V+. Since the humidity is fully discharged again in the course of the thermal regeneration cycle, not only drying the filter at regular intervals, but additionally regenerating it again via its self-cleaning function.
With this innovative procedure the filter resistance remains low and the clean air flow remains at a constantly high level for a considerably longer time. Consequently the lifetime is much longer than that of other filter systems without thermal regeneration and decontamination. This is also confirmed by current studies, which sum up as follows in the context of an examination of the TAC V+ and its H14 filter which complies with the specifications of EN 1822 (ISO 45H filter ISO 29463) and which features a self-cleaning function: "Therefore it is to be expected that this filter can have a lifetime of several years, depending on the load."
Low-noise: Hard to believe, hardly to be heard
The TAC V+ is an an air cleaning revolution of the silent kind
The task of qualified high-performance air purifiers is to make the utilization of interior spaces possible again – and not to make it more difficult! Nevertheless, without large volumes of clean air, the risk of infection cannot be minimized!
When aerosol particles are separated or viruses and bacteria are filtered out, high air circulation rates between 6 and 8 per hour are required, and in the medical sector even 12- to 15-fold air circulation rates per hour. Without these large air circulation rates, spontaneously occurring aerosol clouds cannot be reliably and quickly diluted and filtered out.
Therefore, even in smaller rooms of 45 m² you already need amounts of clean air from 700 m³ to 1,500 m³, which requires a fan with a correspondingly high ventilation power. In particular to establish an optimum air flow and air routing in the room. In addition to the flow geometry, filter efficiency and long filter lifetimes, however, an acceptable noise level, in spite of the large air volumes and the high fan performance, is desirable.
This is why one of the top priorities in the design of the TAC V+ was a low noise emission
For noise sensitive areas such as schools, offices or medical practices we recommend using the optional sound protection hood by means of which the sound level experienced subjectively can be again reduced by more than 50 %! In workshops, packing stations or discotheques, etc. the use of the sound protection hood usually is not required.
With an optional H14-Ultra-Highflow filter and an installed sound protection hood, the TAC V+ for example merely generates approx. 45 dB at level 3 with a clean air flow rate of 1,000 m³/h. For comparison: A customary laser printer already generates a sound level of approx. 50 dB during operation.
The TAC V+ is flexible, mobile and can be used everywhere at any time
The extremely stable, robust and scratch-resistant metal housing was specially designed for the use in environments where many people come together, work, play, learn or celebrate. This makes it possible to use the TAC V+ everywhere it's needed without any installation effort.
Flexible, mobile and modular – the exact number of TAC V+ devices required by the hygiene concept can be provided in each case. Variably adapted to the staff density, security level, type of application, background noise, room size and room geometry. The optionally available hose adapter makes it possible to also connect the TAC V+ to existing air distribution systems.
Where the effective control of infection risks due to aerosol particles is concerned, high circulation rates and therefore large and flexibly adjustable volumes of clean air are indispensable, despite promises to the contrary made by other providers who advertise single to threefold circulation rates per hour as sufficient.
To meet these requirements, the virus air cleaner not only has to be able to provide corresponding volumes of clean air, but it must also be flexibly placeable directly in potential hazard zones to ensure effective air routing. The TAC V+ is also optionally available in a tamper-proof version for the use in schools or daycare centres.
Scientifically proven: Only sufficiently high air change rates and proper positioning of the devices with respect to the air flow and routing provide a sufficient level of protection against an infection risk.
Well thought out to the detail, unparalleled in its entirety – the six benefits of the TAC V+ at a glance:
- Large clean air capacity: Up to 2,200 m³/h of virus-filtered clean air with a high flow pressure for optimum air circulation and high air circulation rates

Triple indicator for healthy room air: Our BQ air quality measuring devices indicate all important values
The Air quality monitor BQ30 should not be missing on any teacher's desk or in any open-plan office because this environmental monitoring station shows you the most important values for healthy room air at a glance: In addition to the current CO2 load and the prevailing climate data and the particulate matter pollution in particle size PM2.5 or PM10 are shown to you.
The CO2 pollution is an important indicator of required ventilation measures and the fine dust particle sizes determined also include pollen, a helpful feature to monitor the air quality for allergy sufferers! In rooms with a large number of persons, CO2 Traffic lights can serve as a means for rough-orientation to indicate whether the air quality is good or poor, as carbon dioxide (CO2) is a reliable indicator of an air change.
In addition to the BQ30 Trotec's range of products includes further professional particle counters such as the PC200 or the PC220. Our particle counters cannot only be used for inspecting the air quality, but to test filter systems as well, for example.
Note: Neither the degree of air pollution caused by particulate matter of the particle size PM2.5 nor the CO2 pollution in the room tells you anything about the infection risk! None of the two values are a measurand of the risk of infection, since there is no correlation between CO2 or PM2.5 concentration and viral load.
