FAQ'S
The LD systems are used to remove pollutants, pathogens such as viruses, bacteria or dust, allergens and odors from the room air.
In recent years, air purifiers with different cleaning approaches have come onto the market. Some systems only rely on HEPA filters, other systems on UV-C light for disinfection, and some manufacturers still combine with activated carbon filters. That is not enough for us!
A single system can lose its effectiveness, a HEPA filter without an additional cleaning stage could, for example, allow harmful substances to pass unnoticed through micro-breakthroughs. A heat source that is supposed to eliminate pollutants in the filter does not help at this point.
ETS combines all recognized cleaning systems in one air cleaning system!
A multi-stage filter system consisting of a pre-filter, plasma filter, activated carbon filter, titanium oxide filter and HEPA filter as well as aggressive UV-C light completely cleans the air and kills viruses and bacteria.
The number of 3 air changes per hour is generally recommended as an absolute minimum for a quiet area; significantly more frequent air changes are required in busy areas. A minimum of six air changes is recommended for normal public traffic and tenfold and higher for sport or heavy public traffic.
The specification of the air volume per m³ cannot be understood as well as the specification for cleaning related to an area. With other providers, devices start with an output of 80m³ / hour, for example. With a ceiling height of 2.50 m, the air would be exchanged on 32m² once an hour. With the minimum change of three times an hour, only 10.66m² remain, with six changes only 5.33m² – that’s not even enough for a toilet room.
The same example for the AP-90 with a capacity of 720m³ / hour. With a ceiling height of 2.50, this equates to 288m² for one change, 96m² for three changes – the number in the model designation rounded off.
The coronavirus continues to baffle scientists. According to a recently published study, laboratory tests have shown that the virus is heat-resistant, self-healing and extremely resilient. The Hungarian researchers also ignore the hope that heat will damage the virus. Kellermayer and his colleagues heated virus particles to 90 degrees for ten minutes and found that the appearance of the particles changed only slightly. Some spines would have loosened under the scorching heat, but the overall structure remained intact. “According to these findings, a virus cannot be eliminated if it blows past a heater in milliseconds in the air flow!
No – the systemsg work in an environmentally friendly manner without chemical additives, the housing is encapsulated, and no UV radiation is emitted. Safety switches prevent accidental activation during maintenance work. Ozone is a component in the complete system that is generated by plasma. Due to the instability of the ozone, it is necessary that the ozone is produced directly at the point of use. The ozone output is max. 8 mg / h and is far below the limit value of 50 mg / h. Ozone is an unstable compound that breaks down instantly.
As a single filter with fan, as is used in some converted construction dryers, an H14 makes sense, but with multiple filter systems such as those from ETS, which also clean with activated carbon, plasma, TIO, UV-C etc., this does not make sense in relation to the cleaning performance still makes sense to the desired amount of air cleaning. The H14 filter significantly reduces the air volume and the devices are inevitably louder or not as efficient in terms of air flow. Our devices run with multiple filters, which provides a much higher cleaning performance than a single H14 filter. According to the Institute for Building Physics, Environment, Hygiene and Sensor Technology, the problem of a breakthrough exists when cleaning the air with pure HEPA filters. Ie HEPA filters clog over time, especially in rooms with a large number of people and changing airflow conditions. With increasing clogging, the suction through the internal fan increases and at some point the HEPA filter breaks through; initially in the nanometer range, so that viruses can pass through the filter, later also to coarser breaks. From the outside, however, no damage or reduction in performance can be seen with the naked eye. Therefore, with HEPA filters, in order to achieve 100% reliability of the effective power, the filters actually have to be replaced every month in live operation. From the outside, however, no damage or reduction in performance can be seen with the naked eye.
SARS-Cov 2 or Corona currently dominates the topic of air cleaning systems. As a result, the systems have now also become popular with us. The systems are now used everywhere where the quality of the indoor air is important and pollutants need to be reliably removed.
These are for example:
Business rooms, exhibition rooms, offices, seminar rooms, trade fairs, pubs, restaurants, bars, retirement and nursing homes, hospitals, communal accommodation, waiting rooms, sports facilities & fitness studios, wellness areas, changing rooms, living rooms, bedrooms and much more.
However, there are many more areas of use than are currently in focus, here are a few examples:
These systems can bring relief, for example, to allergies to pollen or dust. In Germany alone there are over 20 million people allergic to pollen and around 8 million people are allergic to house dust. The number of possible allergenic substances in indoor air is by no means limited to pollen and house dust. Other possible allergy triggers include a wide variety of chemicals, mold spores, pet dander and pet hair. In many cases, these systems can also greatly reduce exposure to these allergens.
The systems can in some cases significantly reduce symptoms of asthma indoors. The causes of asthma are very diverse. In addition to a genetic component, allergens and environmental pollutants (such as VOCs) in the room air often play a role in the development of asthma. In Germany around 7% of the population suffer from asthma. The incidence rate in children and adolescents is almost twice as high. The systems can largely filter allergens and pollutants that cause asthma from the room air.
The systems can often greatly reduce unpleasant smells indoors. Unpleasant smells in buildings can indicate that the room air is polluted with chemicals. Mold and tobacco smoke also give off odors that often cannot be adequately eliminated even by ventilation. Some chemicals and molds can damage health even below the human olfactory threshold. Not only do they eliminate unpleasant odors, they are also able to bind harmful substances.
The systems can hold back the pollen that causes hay fever to more than 99% with a multi-stage filter system. Therefore, the devices are also recommended by major health insurance companies for people allergic to pollen. Hay fever is caused by an overreaction of the immune system to pollen. The pollen are identified as the body’s supposed “enemies” and combated. This defense reaction causes the typical symptoms of hay fever to occur: runny and blocked nose, urge to sneeze, red, itchy and inflamed eyes.
The histamine released by the body in response to the pollen plays a large part in these symptoms. Air purifiers against hay fever are useful indoors, as the pollen concentration there often reaches similarly high values as in the outside air. In some cases, the pollen concentration in the indoor air can even be higher than outdoors. This can happen if pollen deposited is whirled up in large quantities by vacuum cleaners, dusting or drafts. The use of the systems is particularly useful in the bedroom, as hay fever sometimes makes restful sleep very difficult.
