This section contains information of air conditoners in Singapore with regrads to product features and technology.



Negative Ionizer, Ozone Generator, Plasmacluster

There are so many air purifiers in the market that claims their product is able to eliminate the most harmful 'stuff' in this 'dirty' world of ours. Some claimed their technology are tested by private labs or supported by government agencies. They used 'realistic' examples to demonstrate their product capabilities but how true is it really...until some researchs and papers are published by some well known professors, i choose not to comment much.
Negative Ionizer
In nature, there should be a balance of postive and negative ions. But in urban settings, due to the pollutants emitted by various sources, the postive ions are in far greater quantity than the negative ions. Some researchs have shown that lack of negative ions causes some 'Sick Building Syndrome' while the increase of negative ions promotes well being and fewer respiratory complaints. This point can be explained why we feel more relaxed and calm in mountains, forest or near waterfalls as these areas have high concentration of negative ions.
The ionizer generates negative ions which 'clings' themselves onto air particles which results in either the particles settle to the ground or stick to walls or furniture. Therefore in simplier terms the particles are removed from the air but not from the room.
Generally, ionizer are referred as air refresher rather than air cleaner. Nevertheless, the increase in negative ions does somewhat promotes better health benefits though to what extend is still unsure.
Air Conditioners brands with ionizer includes Panasonic, Toshiba Daiseikai, McQuay, Haier and FujiElectric.

Ozone Generator
This is probably the most controversial of the three. And some research or papers even mentioned that it is potentially dangerous. In simple terms, these Ozone generators produce ozone which is an air pollutant itself, smog. Funny huh? A pollutant used as an air cleaner.
To some extent, Ozone when in very high concentration is able to effectively remove mircobes. But at the same time, humans in such a high concentration of Ozone will experience negative health effects. In some applications, an Ozone Generator is used to 'purify' a room when the occupants are not present. But till then there are no conclusive research done on the possbile chemical by products left behind after the 'treatment'.
Therefore I will recommend readers to take extra caution when purchasing air purification products with ozone generation capabilities or uses names like 'activated oxygen' and similar terms. In any case, it will always be safer to purchase products from International Brands with reputable history and track records in environmental issue rather than from a 'dun known from where' brand.

Plasmacluster Ionizer
Plasmacluster technology is a break through by Sharp in air purification technology. Plasmacluster is based on the nature way of air purification process by which of a postive and negative ion shower. The main difference is PLASMACLUSTER actually disactivates the bacteria (research shows it is effective against mold spores and odors) thus causing no harm to us anymore. It is relatively similar to the Ionizer in principle just that in addition to weighing down the particles, it also deactivates the bacteria*.The Plasmacluster ion generator making use of the water molecules and oxygen molecules, produces both postive and negative ions.
* Its capabilities are still not determine conclusively.
