There are now many different types of car air purifier to choose from, but they all have essentially the same main function of purifying the air inside your car. As a result, when choosing yours, think about which is best suited to your needs and power supply with the advice below. First of all, you must determine the size of the purifier. For instance, if you own a small car or a compact car, you will not want to get a large or massive purifier. However, most cars these days come standard so that isn't an issue, just make sure you know what kind of purifier you want before you go looking.
Another important factor to consider when buying a car air purifier is if you want an ionic or a mechanical filter. An ionic filter is made of a negatively charged ion and a positive ion. The process of creating the negative ions is through the use of a coil or a magnet. This then attracts particles like dust and dirt, which traps them within the coil or the magnet. The purified water then flows through the motor, which filters out impurities.
Mechanical filters, on the other hand, use mechanical pressure to filter particles and traps them. This then makes a fresh breeze pass through the motor and into the vehicle, much like the Fresh Air fresheners that you can buy everywhere. The problem with this type of car air purifier is that because the pressure and the speed of the airflow are low, it doesn't really work very well. That's why fresh air fresheners always work very well - because they force the air through a filter that traps and removes all those particles that are not fresh.
An activated carbon filter, on the other hand, uses chemicals and oxidation to filter the particles. The activated carbon filters remove large airborne particles while leaving the good, natural oxygen molecules untouched. Studies show that activated carbon filters are very effective in removing allergens from the air and removing other toxins from the vehicle's air. Some manufacturers of car air purifier systems recommend adding anti-allergen materials to the filter, such as polyethylene.
A newer technology used in many newer car air purifier systems is called ion exchange. Ion-exchange filters use a porous ceramic filter with positively charged ions and negative ions. These negative ions bind to harmful airborne particles, removing them from the air. Studies show that these types of filters are highly effective at eliminating dust and pollen, as well as other common allergens. However, the filter itself doesn't get rid of every single one of those allergens - the filter's electrostatic attraction only allows the pollutants to bind to the filter. So, even though the air is cleaner with an ion-exchange filter, the individual particles of pollutants are still trapped.
Air purifiers work to rid the car of air borne germs, pollen, and other harmful contaminants. But they're not perfect. Airborne bacteria and viruses can be transported by wind, transported by snow, and carried by water. This means that a car air purifier can't be completely efficient, because it's up to you to keep the vehicle clean.
