If you were asked to explain the difference between an air cleaner and an air purifier, would you be able to. Do not worry if you cannot answer, as you are probably the same as the majority of folks who do not understand the difference between the two. Briefly, an air cleaner will filter harmful particles from the air while an air purifier kills bacteria, mold and viruses. Although ionic air purifiers are called "purifiers," they are not strictly purifying the air as they unable to kill organisms. Instead, air ionizers are an air cleaner.
What do Ionic Air Purifiers Do
Ionic air purifiers, also called air ionizers, are built around a negative ion generator. This generator continually sends out a stream of negative ions, which are atoms or molecules that have lost an electron.
These negative ions are attracted to the positive airborne dust and allergen particles in the air. As a result, the negative ions join with the positive ions, which cause the particles in the ionic air to become heavy. Eventually, they fall to the floor because of their own weight, which in turn removes all sorts of particles from the air.
Ionic air purifiers or ionizers are popular because, in most folk’s eyes, the science behind them makes sense plus the fact that they are quiet and use little energy. Additionally, it is usually unnecessary to change the air filters of ionizers, unlike many other types of air purifiers.
As explained above, ionic air purifiers cause particles to fall to the floor. However, they can also end up falling to other areas of the room as well. As the majority of surfaces in a room are positively charged, the particles falling from the ionic air are attracted to those surfaces as well. Because of this, you will find that the area around the ionic air purifier tends to get dark and dirty.
Although the ionizer removes harmful dust and allergen particles from the air, it is quite easy for them to be returned. This is because the particles end up on the floor and other surfaces but any activity within the room can quite easily stir them back up which results in the harmful particles being put back into the air. Some ionizers however, have special electrostatic precipitators, which trap particles onto charged metal plates. To remain effective, these plates need to be cleaned on a regular basis
Ionic Air Purifiers Consumer Reports
In May of 2005, Consumer Reports published the results of a study about ionic air purifiers. According to their research, ionizers failed to clean the air. It was also found that an ionic air purifier could add harmful levels of toxic ozone to the air, which has been proven to damage the lungs and the respiratory tract.
If you want to keep you air healthy, an ionizer is probably not the best answer. Using the old adage of prevention is better than cure; your goal should not be to clean the air after it becomes unhealthy but rather take steps to keep the air healthy in the first place. Although maybe not practical, one way to do this is to get rid of carpets and rugs, which collect and hold harmful pollutants.
If you are a smoker, only smoke outside, also refrain from burning candles, and incense indoors. To improve air circulation, look into installing outdoor venting fans in your kitchen and bathroom. Also, keep your windows open as much as possible. These natural air purifier techniques will work far better than any of the ionic air purifiers on the market ever will.
