Guide to ionization in air purifiers

We have all heard of air purifiers and their promise to make air in our homes cleaner and healthier by removing various pollutants that poison it. Some, like the AIRVIA Medical Air Purifier, even boast an ionization function. So what exactly is ionization and what does it do?

Ionization:  long and widely recognised

Some of the most advanced air purifiers come with an "ionization" function. It can be used on a daily basis without any danger, whether it is on constantly or only once in a while, depending on the model and your habits.

Ionization is used in small and large appliances alike, whether for air or water. For example it can be found in kitchen hoods, washing machines and tumble dryers. In these cases, ionization is used to eliminate pollutants, microbes, viruses, etc. A hairdryer with an ionization function can break down water drops in order to dry the hair faster and avoid static electricity effects. Ionization is also used in water ionizers that can make water more alkaline and therefore, less acidic.

Ionization has been used for several decades in the agricultural world. In 1999, a European directive called "Use of ionizing radiation for the treatment of foodstuffs" allowed industrials to ionize food in order to improve their shelf life. This directive is still in use today in several countries across the EU.

How does Ionization work?

Ionization is not a very complicated process once you start visualizing it. If we think back to our physics classes, an ion is an atom that has either gained or lost one or more electrons, losing its stability in the process.

Negative ions naturally occur everywhere in the world. The high density of negative ions is what give us an impression of well-being and freedom when we find ourselves in natural places with wind, sea breeze, solar radiation, rivers, waterfalls, forests, in high altitude... or even in the pressured water coming out of your shower.

Positive ions are exactly the opposite. They are mostly present indoors and in cities, and they are generated by all our machines, computers and polluting devices.

To summarize, ionization is the physical phenomenon of removing or adding electric charges to an atom or a molecule (any particle consisting of several atoms bonded together). Once ionized atoms and molecules loses their electrical neutrality and become an ion, either a negative or positive one.

AIRVIA Medical’s choice for quality: ionization using negative ions

An air purifier with an ionization function simply uses negative ions to clean up the air. The device generates negative ions in large quantities which will bond with all the positive ions they encounter: dust, VOCs, harmful microparticles, pollen, microbes... Pollutants will be weighed down, fall to ground and therefore be eliminated from the air you breathe. They will not get a chance to get in contact with you and impact your health. Negative ions have the same effect on smoke, including cigarette smoke, and kitchen odours.

Keep in mind that some products use a form of ionization that can lead to the emission of harmful gases such as ozone. When inhaled on a daily basis, even in small quantities, these gases can be dangerous to your long-term health. They can cause damage to the mucous membranes of your lungs and irritate them. So make sure to invest in a latest-generation air purifier such as ours which guarantees a healthy and safe ionization process! AIRVIA Medical only uses a negative ions ionization system that is 100% safe and does not emit any gas.

Ionization in air purifiers is effective against all pollutants that vitiate our indoor air, whether at home or at the office.
