Over the years Kontak has the attention of audiences with a range of environmental vaporizers of pure propolis, proposing different models for design and functionality.

Continuous scientific research and field trials have determined the validity and reliability of the system Propolair with the use of raw materials of the highest quality.

The only manufacturer with pure organic Italian propolis

Kontak was founded in 1990 by the genius of Luigi Fabretto, inventor of Propolair propolis vaporizers, an innovation in the exploitation of this valuable natural substance.

STUDY OF ASL 5 COLLEGNO ON SANITATION MICROBIAL IN A CLASSROOM SCHOOL (Biologi.Italiani February '96)

Using for 3 consecutive days the diffusers in to the schools and after to have analyzed the Air before and after the experimentation, some comments can be made on the antibacterial activity of sesquiterpenes.

Utilizing Propolair diffusers there was a strong microbial load reduction (71,8% in 3 days).

Acido Ferulico: Aboca/Esi/Specchiasol /Biosline: ASSENTE Kontak : 0,83 Ferulic acid was initially used in the studies of biochemistry and immunology to understand the metabolism of arachidonic acid branch that leads to the synthesis of leukotrienes. These biological derivatives are potent mediators of inflammatory reactions and have some activity 'in the symptoms of bronchial asthma. Based on these studies it was possible to synthesize derivatives much more powerful results that are truly effective in controlling asthma attacks.

The caffeic acid is an aromatic carboxylic acid. So called because it was originally found in the extracts of coffee,

it was subsequently found widely in nature. As such, and derivative (caffeic acid / chlorogenic) is present nell'angelica,

nell'arnica in burdock, in the flue, in melissa and high percentages in propolis quality '.

As such it has antibiotic properties towards certain intestinal pathogens. It has weak anti-inflammatory effect and is shown to inhibit the enzyme xanthine oxidase, which converts xanthine

into uric acid, gout responsible for the phenomena when excessively present in the tissues.

The results confirm that Propolit of Kontak is: - More rich in phenolic acids Total * - More rich in flavonoids * * Compared to the propolis Aboca, Specchiasol, Esi and Biosline

Field Experience

Prof. Matteo Bevilacqua Respiratory Physiopathology Service, Hospital of Padua (Italy)Prof. Luciano Pecchiai Head Pathologist in “Vittore Buzzi” Children Hospital of Milano

(Italy) To Take Care of Health with propolis (Prof. Luciano Pecchiai – Milano (Italy) I made my personal experience using Propolair with 200 patience with respiratoy disease, like

rhinitis,sinusitis, bronchitises, tuss and sometimes asthma. In each case we obtained a reduction of sintomatologies and an improvement of disease course, and a reduction of the fever when it was present.

We obtained the best results in children with recurrent form of faringitises and tonsillitises from streptococcobetaemholitics.

Prevention and therapy for respiratory diseases. (Prof. Matteo Bevilacqua – Padua

(Italy) Propolair finds its most natural use in respiratory medicine because it allows all these active substances

to reach the whole surface of the respiratory tree at its best, starting from the nose and the mouth, down to all the ventilated alveoli, at its main concentration, beating the enemy on the spot and avoiding diseases of the organism.

Propolair is specially fit for the prophylaxis and therapy of respiratory acute and chronic diseases which present allergies, inflammation, bacteria, viruses and fungae, such as: rhinits, sinusitis, tonsillitis, pharyngitis, laryngitis, mycosis of the throat, bronchial asthma, asthmatic bronchitis, chronic obstructive bronchopneumopathie.

The ionizator and the fan placed inside the Propolair highly increase the effectiveness of the inhaling system.

Scientific Studies

A chemical analysis was carried out by us in order to determine the main components of the volatile fraction of propolis released into the atmosphere by PROPOLAIR. The identified components have been assembled into the following table.

A research, whose data were extracted from Medline scientific data bank, has analyzed these components one by one. (see scientific bibliography in website: www.propolair.com) EXAMPLE: BENZYL ALCOHOL (present in all cycle of capsula propolair), demonstred an antifungingal activity NONANAL (also present in all cycle), showed a strong activity against Staphylococcus aureus, Klebsiella Pneumoniae and Escherichia Coli. LINALOOL (present just in the first 24h of capsula propoliar) demonstred very strong antibacterial activity For each compound the data indicate its therapeutic validity and property together with the scientific experimentations carried out on it.
