Big cities with their factories and lots of cars cannot provide people with clear and fresh air. Air ionizers, devices that purify air, become more and more common tools in people’s everyday life. Still, air ionizers do not guarantee to provide you with salubrious air.

Air Ionizers

Physical and chemical characteristics of particles are the basis of air ionizers’ work. Ions are particles that can be charged either positively or negatively. A room ionizer uses electricity and produce negatively charged ions that attach onto positively charged particles, such as dust, bacteria, pollen, smoke, and many other allergens present in the air.

As we know from the physics course, oppositely charged particles attract. After being connected particles become heavy and fall down forming larger pieces of dirt on the floor that can be easily cleaned by common tools like a vacuum cleaner.

Air ionizers differ from ozone generators, though they both work in a similar way. Nevertheless, even the best types of air ionizers produce some amount of ozone that is quite toxic for people and animals.

What is Ozone?

Ozone (O3 or triatomic oxygen) is a pale blue gas that has a pungent odor. Ozone can be generated naturally, for example by lightning or waterfalls, and unnaturally by special devices as ozone generators or when air pollutants expelled from power plants, cars, etc., react chemically to the sunlight.

Ozone is present in the atmosphere in low concentrations and in high concentrations in the ozone layer of the stratosphere, which helps to absorb UV radiation.

Ozone produced by air ionizers help to kill bacteria and purify a room from pollution and poor odor. The ozone that is produced in the process of generation of negatively charged ions breaks air contaminants into smaller elements that can make no adverse effects to your health. In addition, ozone prevents dangerous germs from growing.

Nevertheless, while high concentrations of ozone in the ozone layer are beneficial, they are harmful in the atmosphere layer as they cause respiratory problems and reduce lung function.

Adverse Effects of Ozone

If you use an air ionizer in a small room without ventilation, ozone level can exceed the acceptable amount (which is higher than 0.1 ppm/0.2 mg/m3 a day). High level of ozone concentration in the air can damage your lungs. Many studies show that ozone can make a reaction with cleaning agents thus forming pollutants such as formaldehyde.

So, it is important to buy an air ionizer instead of ozone producer for the living places, as air ionizers produce small amounts of ozone which is not harmful to health.

Reasons for Buying Air Ionizer

Air ionizers can be used for the following purposes:

  • to keep the air in a room fresh and cleared out of pollutants, hence beneficial for health;
  • to eliminate the smell of tobacco and tobacco smoke (it is made with the help of ozone);
  • to clear dusty air

How to Choose an Air Ionizer?

When choosing air ionizer it is better to find the one that is designed for a room smaller than yours. In this case, you can be sure that the amount of ozone produced by the ionizer will never exceed the permissible level.

The advantages of ionizers are:

  • they don’t consume a lot of energy;
  • they work silently;
  • they are convenient in use, as you don’t have filters to change;
  • some of them have special devices for catching the particles of dust that fall on the floor.

If you have respiratory problems, asthma, or allergy, it is better to choose a salt lamp, which is a natural ionizer and produces no ozone.
