LEA® – Laminar Electrode Array
The technology in detail
The operating principle
LEA®’s operating principle is the electrokinetic inactivation of pathogens. With the aid of a scalable, flat matrix of special microelectrodes, LEA®’s electronic control unit creates an electric field that delivers repeated and powerful kinetic and electric shocks to attack viruses, bacteria and mould spores. These repetitive electrical impacts, delivered at a frequency of varying polarity, destroy the pathogens’ cell structure and render them harmless Pathogens with particle sizes down to 0.1µm are inactivated at a rate of up to 99.99992%. Unlike conventional ionization – or cold plasma-based systems, LEA® produces no dielectric barrier or corona discharges, thus completely avoiding the emission of harmful by-products such as ozone or NOx.
Test results
Laboratory studies and tests in the medical environment have shown that LEA® ensures an extremely high inactivation rate for various pathogens, including viruses, bacteria and mould spores.
VIRUSES: SARS COV 2 and Influenza surrogate
MS2 Bacteriophage
Substitute for influenza, SARS-CoV-2 and other RNA viruses
Result
Rate of reduction achieved: – 99,99992% in 90 minutes
This shows that LEA® can effectively reduce and inactivate airborne influenza, SARS-CoV-2 and other RNA viruses.
2.
Bacteria: dangerous hospital germs
Klebsiella aerogenes
Substitute for Klebsiella pneumoniae – a hospital germ that can cause severe pneumonia, urinary tract infections or sepsis.
Result
Rate of reduction achieved: -99,99967% in 45 minutes
This shows that LEA® can effectively reduce and inactivate airborne Klebsiella pneumoniae.
3.
Bacteria: dangerous hospital germs
Staphylococcus epidermidis
Substitute for methicillin-resistant Staphylococcus aureus (MRSA) – a common cause of hospital-acquired infections.
Result
Rate of reduction achieved: -99,99993% in 90 minutes
This shows that LEA® can effectively reduce and inactivate airborne Methicillin-resistant Staphylococcus aureus (MRSA).
Fungal spores
ASPERGILLUS BRASILIENSIS NIGER
Toxic black mould
Result
Rate of reduction achieved: -99,9958% in 60 minutes
This shows that LEA® can effectively reduce and inactivate airborne toxic black mould.
Ozone
Test to prove that LEA® emits no harmful ozone and presents no risk to the user.
Result
Ozone concentration over the course of the whole test period: ≤0.001 ppm.
The test showed that no detectable ozone levels were produced by LEA® during the trial.
LEA® in comparison
Clinically pure air – where it is needed
LEA® was originally intended for use in medical installations, more specifically for use in patient rooms and on the ward. Hospital safety and hygiene regulations require that the highest standards of indoor air quality be maintained in patient rooms. This can require the use of air purification systems. However, conventional systems are mostly unsuitable. Devices with integrated passive filters, e.g. HEPA filters, generate increased noise levels of at least 35dBA, due to the disturbance of airflow during operation. With other technologies such as UV, ionization or non-thermal plasma, ozone or NOx production cannot be completely ruled out. LEA® was developed in order to meet the highest required levels of safety and patient comfort and to avoid the disadvantages associated with conventional systems described above.
Proven to operate completely without the emission of by-products such as ozone or NOx, and featuring extremely quiet operation, LEA® sets new standards of safety and comfort – for patient rooms as well as for many other types of indoor environment.
