For better health, owning and using an air purifier for your car should be an essential part of your maintenance plan. Most cities have poor air quality and many allergy sufferers suffer every day. The air inside of a car's cabin can also be contaminated in three ways: indirectly through ventilation (pm, NOX, CO), directly through the skin (through pollens, dust mites, dust) and through the nose (due to the constant exchange of air with the outside world). In-cabin contamination (smoker's cough, VOCs, etc.)
The best features in an automobile air purifier are the ionizer and the nebulizer. An ionizer is a filter that takes negatively charged particles such as pollen, dirt and dust and traps them within a filter mesh. The mesh is much like a sponge and has millions of negatively charged particles trapped within it. A nebulizer is a special device that combines the ionizer and the filter into one convenient device.
To keep a car air purifier working at its peak efficiency, you need to make sure you change out the filter at least twice a month. The in-car air purifier filter is usually made up of polyurethane foam, activated carbon and micron filtration. If there is a build-up of toxins and grime on the filter, it will clog the mesh and the purifier will not work. The most effective way to clean the filter is to use your car vacuum.
The charging options for these portable purifiers are important to consider. Most models have standard USA wall outlets but you may find some European or Asian ones available. These cars portable purifiers are smaller than their full size brothers and therefore smaller outlet cords would be more convenient. Charging options will vary between brands. Most of the newer purifiers have built-in lithium ion batteries.
