The facts about air quality


We all want our homes to be safe and clean for our families. But the air in your home can be 2 to 5 times more polluted than the air outside.

The facts about air quality

The impact of air pollution

Air pollution can have a number of impacts on your health. The most common symptoms include headache, inflammation, nasal congestion, respiratory problems, skin irritation and stomach pain.


Philips air purifiers clean the air from these common pollutants

Philips air purifiers have a multi-stage filtration system that captures up to 99.97% of harmful particles, from dust and allergens to aerosols and PM2.5 particles.


*From the air that passes through the filter, tested with NaCl aerosol by iUTA according to DIN71460-1.

**Respiratory droplets and aerosols can carry smaller particles within them, like dust or coronavirus.

What CADR means for your home

The Clean Air Delivery Rate is the global standard for measuring how much air (m3) a purifier

can clean in a certain amount of time. So, the higher the CADR, the faster the purification.


Airflow only measures wind speed, so it only tells us how much air is coming out. What airflow

does not tell us is how clean that air is. This is why CADR is the right metric to use when choosing your purifier.

Aerosol transmission

The World Health Organization (WHO) confirmed that COVID-19 can also be transmitted via aerosols.


WHO considers contact and droplets major routes of transmission for Covid-19. Aerosol transmission can occur in specific settings, particularly in indoor, crowded and inadequately ventilated spaces where infected people spend long periods of time with others, such as restaurants.

WHO’s primary role is to direct international health within the United Nation’s system and to lead partners in global health responses.

Air purifiers

How air purifiers capture viruses


An indoor air purifier detects and captures pollutants in the air, including aerosols that can contain viruses. The particles get trapped by the fibers of the HEPA NanoProtect filter, and clean air is released back into the indoor space.

What are aerosols?


Aerosols are solid or liquid particles of small size (<5 micron), that remain airborne for prolonged periods – and can carry viruses.

How do HEPA NanoProtect filters in Philips air purifiers help reduce the spread of viruses?


Philips air purifiers create circulation in an indoor environment, which draws air through its filters and chapters viruses together with other pollutants as small as 0.003 microns.

How are aerosols linked with virus transmission?


Viruses can spread from an infected person’s mouth or nose in small liquid particles when they cough, sneeze, speak or breathe. These particles range in size from larger respiratory droplets to smaller aerosols.

Once the virus is captured by the filter, what happens to it?


The virus will lose viability since there is no host cell inside the filters.

How Philips Air Purifiers can help your business

Independent study

Our air purifiers have been independently tested in schools, showing effectiveness in aerosol removal


An independent study from the Goethe University in Frankfurt, Germany demonstrated that the use of portable air purifiers can help reduce aerosol levels in a classroom. Based on the experimental findings and subsequent theoretical modeling, the investigators concluded that air purifiers are an important additional measure of precaution.

German Stiftung Warentest tested how well the winners of the Air Purifier Test March 2020 catch aerosols (Jan. 2021)

*Aerosol is a mixture of air with solid or liquid particles. It is maneuverable, constantly changing and can hardly be managed.


How allergens attack

Your immune system's job is to defend your body from harmful invaders such as bacteria and viruses. But when it mistakenly declares war on substances it shouldn’t, that’s an allergy.
