Do air purifiers help against aerosols?

Viruses are composed of one or more molecules and may be enclosed in a protein coat. These molecules contain the genetic material with the information for their multiplication. Their tiny size is limited to 20 to 300 nanometers, but Philips air purifiers are capable of removing particles as small as 3 nanometers from the room air. This makes them ideally suited as air purifiers for viruses.

Viruses are not independent living organisms, as they do not have their own metabolism for energy production. So far, about 3000 different types of viruses are known. Depending on the species, viruses can be contagious in different ways and transmit different diseases. The duration of infection is usually a few weeks. Using a special air purifier for viruses can actively protect you from contracting such a viral disease.

Filtered air: air purifier against viruses

Can air purifiers against viruses help? Yes, because certain viruses are transmitted by sneezing or coughing, via so-called droplet infections. In the process, pathogens can be released into the air through droplets of saliva – just like when we speak. Philips air purifiers use a HEPA (High Efficiency Particulate Air) filter to remove 99.5% of airborne viruses and aerosols. Filtration provides clean air and can significantly reduce the risk of droplet infection.

No matter if you live in 50 or 100m2 – there is a Philips air purifier for every room size. Please note, however, that an air purifier alone does not protect against a viral disease. However, it can help to protect you and your environment. In addition to an air purifier against viruses, other protective measures may be useful. A list of these can be found in the last section.

What protects against viral diseases?

1. Vaccinations: Vaccines stimulate the immune system. Viral diseases can therefore be eradicated by adequate vaccines, such as rinderpest in 2011.
2. Hand washing: When infected people sneeze into their hands, the viruses stick there and can be easily transmitted. Thorough and regular washing of hands can prevent such a smear infection.
3. Water treatment: Specifications of the Drinking Water Ordinance usually allow drinking water to be consumed without hesitation, but viruses can still be transmitted via water in individual cases. Especially when traveling you should keep this in mind.
4. Avoid contacts: Keep your distance from other infected persons and move if necessary. Meetings where you are together in closed rooms. If this cannot be avoided, an air purifier against viruses can help to protect against infection. Wearing a mouth-nose protection is also recommended. Contact with infected persons should be completely stopped until they are fully recovered.

Viruses or bacteria?

Bacteria, unlike viruses, consist of a cell with its own metabolism. They multiply by cell division, while viruses can only multiply with the help of a so-called host cell.

Bacteria are responsible for bladder infections or food poisoning, for example. If an illness is caused by bacteria, antibiotics can provide relief.

Diseases like the flu or COVID-19 are caused by viruses. This is where the preventative use of an air purifier against viruses can be particularly useful, because antibiotics have no effect on viral diseases. In addition, unlike bacteria, vaccination can provide protection in the case of viruses. In the case of viruses, such as the flu virus, this has the disadvantage that this vaccination must be administered again every year. This is due to the fact that the virus mutates and in this way tries to infect as many people as possible. If vaccination is out of the question, if you are afraid of getting sick, you should follow all other precautions as strictly as possible.
