How does an ioniser work?

Positive and negative ions: what is the difference?

On a daily basis, we are confronted with two types of ions: positive and negative ions. Positive ions, despite their name, are associated with polluted environments.

We are constantly surrounded by positive ions even if we do not live in an urban environment or in a polluted environment (where they are most present). Our household appliances, screens, tobacco, or even heating systems produce a large amount of positive ions in the ambient air. These tend to accumulate in enclosed spaces (office, car, house, etc.). Positive ions can cause various pathologies such as chronic fatigue, headaches, nausea, or even a feeling of unease.

On the other hand, negative ions have positive effects on our bodies. They promote exchanges between cells whose membranes are electrically charged while also improving the penetration of oxygen (which, as a reminder, is negatively ionised) in the lungs. They also stimulate the action of enzymes and stimulate the secretion of neuromediators (serotonin) and hormones (cortisol). The result is clear: with a higher level of negative ions in our surroundings, we notice a significant drop in the level of stress, better concentration, better sleep, and/or quite simply an improvement in our mood. Negative ions are found in large quantities in natural areas such as the mountains, the seaside, in the forest, or even in the sun.

An ioniser: an effective pollution control method

In addition to the aforementioned beneficial effects on health, negative ions are also used for their strong ability to clean indoor air by removing fine particles.

How does it work? When negatively charged ions (or “anions”) are diffused in a room, they attach themselves to fine particles suspended in the air, which are neutral or positively charged. This is called electrostatic attraction. By attaching themselves to the pollution particles, the ions will either disintegrate them or weigh them down and cause them to fall directly to the ground, away from your lungs. As a result, fine particles are removed from the air we breathe.

AIRVIA Medical air purifiers are two-in-one purifiers and ionisers. We use bipolar needle ionisation technology with a voltage of 6.0 kV. It is a technique that was developed over twenty years ago and, unlike corona discharge ionisation, does not emit harmful levels of ozone or does so only at an extremely low level.

Using an innovative design that uses eight separate conduction filaments, the ionisation technology used is particularly powerful. Our devices generate more than 20 million ions per cm3, 6.3 million at a distance of 1 meter and 0.5 million at a distance of 3 meters, all with a total range of 5 meters.

How does it work?

On our models, the “ionisation” feature is activated by default when you turn on the air purifier. To deactivate or reactivate it, simply press the “Anion” button on the control terminal. When the function is activated, the icon appears at the top left of the screen. 

Do you often wonder where is the best place to store your air purifier so that it is as efficient as possible? We advise you to place it in a location where the air will circulate around the device, preferably in the centre of a room. Living rooms or bedrooms are preferred since we spend the most amount of time there. A use of 2 to 3 hours per day may be sufficient, but do not hesitate to leave it running continuously if you are prone to allergies or own a business, for example.
