An air purifier is a device installed inside the home. It purifies the air in the room where it is installed. To do this, it removes the various sources of pollution by drawing in air and passing it through several filters to eliminate pollutants before recirculating the air.
In relation to the size of the room where you want to purify the air, it's worth noting that the effectiveness of an air purifier depends very much on its performance. However, for optimum performance, this may depend on a number of factors, such as the medium and so on, but it is advisable to fit an air purifier in every room.
First of all, those interested in knowing the current price of air purifiers :
An air purifier's role is to reduce the spread of harmful residues and also allergic or even viral elements. This is to prevent allergy or asthma problems or others that are related to poor indoor air quality. As a result, air purifiers concern earlier people or companies who wish to protect their health and that of their employees or those around them.
Air purifiers in 2013
In 2013, as you may remember, air purifiers were ineffective, inefficient and sterile concerning its air purification work. During this period, "Anses" (Agence nationale de sécurité sanitaire de l'alimentation, de l'environnement et du travail) had declared a few evidence of ineffectiveness air purifiers, whether in homes or workplaces. At the time, air purifiers came in a variety of models, but were still less popular.
In general, purifiers are based on technologies that are often described as new, but are only vaguely explained. Manufacturers have exploited several operating principles to chemically degrade air pollutants such as small particles or microbes. For the various operating systems, here are the potentially ineffective or even dangerous methods that manufacturers opted for at the time.
- Filtration: it's a simple system, but it requires a lot of air circulation to capture the various pollutants.
- Photocatalysis This system activates a catalyst, often made of titanium dioxide, by means of light or ultra-violet radiation. The catalyst in turn triggers chemical reactions and simply releases organic molecules. And this process vaporizes a final product of carbon dioxide and water vapor. In this case, the pollutants are never destroyed because there is no filter.
- Ionization with filtration In this case, an electronic device ionizes air molecules and atoms as they pass through the system. These newly-charged ions are then trapped by surfaces that are also charged.
- Plasma This is an electronic system that produces negative charges. To do this, the device ionizes the air passing through it, generating free radicals as it is supposed to attack various polluting particles.
- Ozonation It is often used in professional environments. This method involves producing an extremely reactive molecule, ozone (O3). This oxidizes everything that passes through the system, giving up an oxygen atom which, of course, becomes a molecule of oxygen. In designing the device with this system, the manufacturers may have overlooked the fact that the result can be highly reactive and poisonous. So don't breathe in too much or for too long. On the other hand, you do need to air the room generously, as these products can degrade very quickly.
Air cleaners in 2024
Over the past three years, air purifiers have been a key component in the evolved. Previously, there had been a negative opinion from the Anses, which was the reference. In November 2020, INRS (Institut National de Recherche et de Sécurité) had also contributed, then in May 2021, HCSP (Haut Conseil de la Santé Publique) had announced a second contribution.
These declarations set out a clear line about air purifiers. They state that only air purification machines equipped with a high-efficiency filter against airborne pollutant particles are considered effective.
It's worth remembering that, in addition to all the barrier gestures, these types of devices make a major contribution to combating aerosol transmission of Covid-19. However, these devices can be accompanied by a CO2 sensor which can be useful as a containment indicator and can warn occupants when the threshold limit of 0.08% will be exceeded.
Where to find the best air purifiers these days?
You can now buy the air purifier of your choice in stores such as Amazon. On this undisputed e-commerce platform, you will find :
