I purchased this Medklinn Mobile ionizer for RM299 at their Jusco counter during promotion period last year.
The unit comes with 14 days money-back guarantee and 1 year defect warranty. It operates by plugging directly into the cigarette lighter socket of the car and bend it upwards. This ionizer requires no maintenance since it does not operate with filter, and I was told that it can last for at least 6 years.
The function of this MedKlinn Mobile ionizer is to deodourize and detoxify the air in the car. It floods the car's interior with massive amounts of negative ions. Large amount of negative ions (at least 2 million ions emission per second) can effectively remove offensive odours and pollutants such as pollen, dust particles, cigarette smoke and exhaust fumes effectively, thus reducing the risk to our health.
I have tested it with durian, and it's deodourize function works very well. It is a better substitute for car fragrance that most people use in their car, because those fragrance are made out of synthetic chemicals that might be harmful to our respiratory system.
There are many other ionizers available, but might not be as effective due to much lesser amount of ions produced. Some can even be harmful to our health due to too much ozone produced.
They've sent a postcard to me, informing that they'll be exhibiting in this HOMEDEC 2008.
