Do car air purifiers work?

The indoor air is what causing us the allergic reactions most of the time and we do forget that the air in our car may be bad for us too.

  • The engine air filters in cars

The engine air filters are based on filtration media (paper or cloth), trapping debris and particles from getting to the engine’s intake system. they have nothing to do with the air inside the passenger space of the car.

There are 2 types of cabin air filters that may remove the odors and allergens in your car:

  • HEPA cabin air filter

This type of air purifiers uses a really fine mesh that traps large particles (pet danger), but also very small particles (the ones in tobacco smoke is one).

  • Cabin air filters with activated carbon-impregnated filtration media

This type of filters uses activated carbon that is really effective for removing odors.

Even if you’re going to set the HVAC controls to recirculate, the cabin air filter is still going to play in most cars. This is going to reduce the risk for air to enter the vehicle once again, recirculating air that’s in your cabin. this mechanism is going to block any new pollutants to get inside, but it’s also going to filter out existing pollutants.

You should install a fresh HEPA or carbon-impregnated filter in your car for better air quality in your car.

  • The air ionizers

You can go with air ionizers that are made especially for the automotive use. Compact, they’re easy to plug straight into the cigarette lighter socket. They don’t filter the air, and the ionized particles of odorous materials and allergens are going to stick to each other and surfaces, stopping from floating in the air (which is better than nothing). These ionizers are rather small and may not give the best air quality in a car, but they do provide decent results.
