Dust, mold, pollen, cigarette smoke and pet dander are some of the indoor particles which can make the air impure and cause discomfort. They can also cause allergies. Indoor particles can float around the air and as a result you would not be breathing fresh and pure air. To overcome this problem, you can buy an air ionizer purifier. An air ionizer is a device which can help in purifying the air by removing microscopic particles from the air.

How Does An Air Ionizer Work?
The air ionizer requires a power supply. When it is switched on, the electrodes present in the device emit electrons. The electrons create negative ions in the air. These negative ions attach themselves to the positively charged particles such as dander, dust, mold and smoke.  Due to this action, these particles become heavy and settle on the ground. Once settled on the ground, they can be easily removed with the help of a filter or a vacuum cleaner.

Thus an air ionizer works by creating negative ions which make the airborne particles heavy. Some air purifiers come with an in-built air ionizer for better air purity.

USB Ionizer Air Purifier:
An USB ionizer air purifier is a simple device which requires a USB port to plug in and purify air. The USB port provides the power supply needed for the air ionizer. A USB air purifier is recommended at workplaces where computers are present. Just plugging-in the USB ionizer air purifier can help in creating better air quality in the office.

After using an air ionizer, it is important to use a vacuum cleaner or air filter to remove the heavy particles which are settled down. If your filter has an in-built air ionizer, you would have to change the filter regularly for better air cleaning effect.
