Is the coronavirus airborne or not?
Many ask themselves the question of what is airborne or not. The specialists' semantics confuse many and therefore we need to clarify the concepts and whether an effective air purifier can help reduce the spread. That the virus is airborne is confirmed by Professor Emeritus Sven Britton in the program Malou after ten on March 2.
"It is already clear that it is an airborne infection. The virus comes out with the breathing air of the person who is infected. Maybe even before the infected person started coughing", says Sven Britton.
When we sneeze and cough, virus-bearing droplets of varying sizes fly out. Some drops are large and can be stopped with the help of your arm or the drops fall within a meter of where you stand. Other drops are so small that it can be more like a haze that stays in the air for hours. There is talk of an aerosol.
Indoor viruses can spread freely in the home and even enter other apartments via ventilation. Following the SARS outbreak in 2003, a large group of researchers found in a study that a SARS-infected person living in one of 19 36-story buildings in the Amoy Gardens residential area of Hong Kong had infected 321 other people in the area.
The researchers concluded that "airborne spread of the virus seems to explain this large outbreak of SARS in society, and future efforts to prevent and control viruses must take into account the extent of the spread of this airborne virus."

How big is the Sars-Cov-2?
The size in diameter varies from about 60 to 140 nm. In the picture you can see what Sars-Cov-2 looks like with transmission electron microscopy.

Does a Livsdal air purifier capture Sars-Cov-2 that causes the COVID-19 flu?
The particle filter in a Livsdal is an industrial EN1822-certified and individually tested HEPA 13 filter that is used in environments where clean air is absolutely necessary. Some examples are NASA's lunar and Mars landers and in hospitals where operations need to be performed in a clean room and in Ebola centers. When the air circulates through the air purifier, the filter captures 100 percent of the virus. The air purifier captures particles as small as 5 nanometers in size. After one to two days in the filter, the virus in the filter dies.
Does Livsdal air purifier catch other viruses and bacteria?
Yes, the air purifier also helps against bacteria, seasonal flu but also the Norovirus (winter vomiting disease) which has also been shown to be airborne. The air purifier cleans the air in a room about 2-3 times per hour and then catches the harmful particles. This means improved health, lower sick leave and thus lower costs. An air purifier from Livsdal is an investment in both people and companies.
What is the difference between a Livsdal and a regular air purifier?
The most striking thing about Livsdal's air purifiers is the look and the exceptional filters. The air purifier costs more than other air purifiers, but we believe that people are willing to invest in efficiency and a pleasant interior at the same time. Many people today are willing to spend the same amount on furniture as an air purifier from Livsdal. But with an air purifier from Livsdal, you get both a sideboard and an air purifier.
A competing air purifier that can be sold in the price range of SEK 3,000 - 10,000 is forced to compromise on filter efficiency. These air purifiers often use ionization technology, ie they charge the small particles and make them form clusters of larger particles so that a simpler and cheaper filter can be used. Unfortunately, ionization creates ozone as a side effect and ozone can be carcinogenic. To reduce ozone, these air purifiers have a small carbon filter in order to capture the ozone created by the air purifier itself. But if you do not replace the carbon filter in time, you have not bought an air purifier but a product that creates dangerous air pollutants.
