A car air purifier is an electronic device that is plugged into the cigarette lighter or a power port to eliminate all the contamination of air inside the car. It uses thermodynamic sterilization to incinerate the contaminants. The ceramic core inside the purifier has micro-capillaries that are heated up to 200 degrees Celsius. Air passes through the ceramic core through convection and so any impurities in the air like bacteria, pollen are burned and pure air comes out from the other side.

Car air purifiers don’t usually work the same way as the normal air purifiers that we have in our homes. In fact, the design alone is totally different from the home air purifier and the size is quite smaller. But it guarantees you a fresh air free from contamination inside your car. It also takes care of the bad breath that may result into discomfort during driving.

The usual charge available in the air is neutral. But the ionizer emits either positive or negative charge which ionizes the dust or impure particles in the air making them stick or avoid floating on air.

The ozone generators inside the car air purifiers are responsible for getting rid of the bad smell inside your car. The principle behind the ozone generators is that produces ozone that goes and interacts with the substances that cause the bad smell, neutralizing them.

Car purifiers have varying stages of filters. From a filter that traps the large substances like human air to smaller filters that only traps small particles like germs.

Advantages of Using a Car Air Purifier

The quality of the air we breathe should be of good quality at all times because impure air can be hazardous. And we should always put up measures to ensure that the air we breathe is free from any impurities.

Having a car air purifier will remove all contaminants in the air inside the cabin. And if you are asthmatic or allergic to things like pollen or dust then you will find the car air purifier helpful while driving. The design of these kinds of air purifiers took into consideration of people with asthma enabling them to breathe fresh air at all times.

The HEPA (High-Efficiency Particulate Air) technology used to create the filters inside the car air purifiers ensures that air around the cabin is completely filtered and free from any kind of impurities. It is estimated that HEPA efficiency is 99.99 % when it comes to removing impurities that are approximately 0.03 microns.

Air purifiers are able to eliminate the bad smell of cigarette smoke and any type of bad smell that may be found inside your car.

The surfaces of your car may harbor dangerous bacteria that may be harmful to our health when our bodies come in contact with these surfaces. If you are driving with someone who has the flu then it can be transmitted from that person to you through sneezing or coughing. You can risk coming in contact with these impurities by use of a car air purifier.

HEPA Technology

HEPA stands for High-Efficiency Particulate Air. And it is a purification technique where it forces filtration of air through convection process thereby trapping harmful particles that could contaminate the pure air. HEPA filters in-car air purifiers’ work by engaging two stages of filtration where the outer filter stage prevents larger particles in the air from passing through. The inner filtration stage prevents smaller particles like germs from passing through. It technically traps impurities depending on the airspeed. At high speeds, the particles hit the fibers hence trapped. At lower speeds, particles move in a Brownian motion hence easily trapped by the brushes.
