Air pollution has been a concerning issue for several decades. Nowadays indoor air quality has become a public health issue.
Human beings spend 80% of their time in enclosed spaces, whether at home, at the office or in their car. But indoor air is even more polluted than the outside air because there is a lot less air circulation and renewal happening indoors. This is why it can be so beneficial to equip your home or office with an air purifier.
What do air purifiers do?
Prolonged exposure to polluted air promotes the risk of diseases such as bronchiolitis, asthma attacks, colds and many types of cancer. Many pollutants do not only affect the respiratory system but all the organs of our body as well.
To reduce how much polluted air we breathe, air purifiers are a great asset. They can be used anywhere indoors such as an apartment, an office building or even large warehouses. Up until the end of the 1990’, air purifiers were used exclusively for commercial applications. Nowadays they are much more democratized and much more accessible to individuals, both in terms of size and price.
An air purifier’s primary function is to reduce the proliferation of harmful particles or allergens in the air. It can be pet hair, Volatile Organic Compounds (VOCs), fine particles, germs, or anything that vitiates our indoor air. Air purifiers treat the air and can be trap or destroy such pollutants. Of course, not all air purifiers come equal. Some only target part of these pollutants while others do not circulate the air at all. High-end products such as our AIRVIA Medical Air Purifier target all pollutants with close to 100% effectiveness, circulating and filtering the air of a 1000 ft² (100m²) space. It is an ideal weapon to fight asthma or allergy problems in people at risk such as children, the elderly and frail people.
In addition, air purifiers can also be used as a preventive measure. In other words, they are also useful to people who do not show any particular symptom but want to preserve their health. All reasons are a good reason to want a device that filters your indoor air and traps pollution.
Operation principles of air purifiers
Air purifiers filter indoor air and purify it by trapping the different particles of pollution it contains. Air purification takes several stages, which vary depending on the air purifier brand and model.
Quality air purifiers start by sucking the air in. AIRVIA Medical for example is capable of cleaning the air of a 1000 ft² (100m²) space within only five minutes of operation. The sucked in air passes through filters of different sizes and composition.
Depending on the performance of the chosen air purifier, it should be able to remove harmful particles of very small sizes. Thanks to 8 different filtration layer, AIRVIA Medical destroys all particles in the air down to PM 2.5. For optimal operation, it is best to install one air purifier per room, or to move it around, always indoors in an enclosed space.
Purify the air to make it breathable again
Air purifiers remove harmful particles from the air, while preserving those that are good or neutral for our health. While pollution is usually invisible to the naked eye, it will adversely affect your health if you do not ensure good air quality in your home. There are several major types of indoor pollutants and therefore three levels of purification:
- Visible pollutants: pet hair, dust, pollen, etc. These can easily be caught by a prefilter.
- Fine particles, which are natural or chemical substances of varying sizes. These fine particles can be captured by a HEPA filter, ionization, or photocatalyst.
- Viruses, bacteria, and fungi are of variable sizes. Purifiers often chose not to capture, for obvious health reasons, but rather reverse their polarity to weigh them down and make them fall to the ground, far from your lungs.
AIRVIA Medical does not dry the air, emits no harmful gases, and its ionization feature does not emit any ozone.
Why use an air purifier?
During their early years, air purifiers in the western world were used mostly by individuals suffering from allergies, asthma or respiratory diseases. More sensitive to polluted air than the average, this group of people can experience great difficulty breathing.
Nowadays, air purifiers are used by everyone who is mindful of their health: families, city or rural dwellers. Many Asian countries advise their inhabitants to equip their homes with air purifiers. In the UK, many municipalities are also beginning to catch up.
But do not forget to open the windows of your home for at least 10 minutes mornings and nights, in order to renew your indoor air.
The Academy of Medical Sciences also specifies that you should leave your windows ajar at night, when it is not too cold, to evacuate the water vapour produced by occupants.
