FB 350, developed during the last years, a very effective anti viral and anti-bacterial filter system for narghilè use. Filter SHIELD also acts electromagnetically with potent neutralizing effects against viruses and bacteria contained in the smoke sucked from the inside of narghilè. Nevertheless, our research Dr. El Safty (candidate for NOBEL premium for Technology in Japan) confirmed that the mechanism of the filter SHIELD stops even the Ebola virus and other viruses that cause haemorrhagic fevers, preventing replication within the cells themselves. When there is no viral replication within cells, also there is no spread of infection. The researchers found that the neutralization of the virus through the filter SHIELD occurs during the early stages of viral replication. In other words, you are advice always to use the filter SHIELD advance before you start to smoke the hookah. The other interesting facts that researchers found, is a protein and enzyme called Cathepsin B that has been shown to play an essential role in virus replication where electromagnetism affects the activity of Cathepsin B decreasing and thus further limiting viral replication in the cell, and the subsequent spread of the virus to other cells. Finally, by far the most interesting thing, is that the filter SHIELD has also proven effectiveness against other types of viruses such as human immunodeficiency (HIV), the hepatitis B, herpes simplex, respiratory syncytial virus.
