What is Hyundai Clean Air?

Jack R. Nerad | Jul 29, 2020

Hyundai Clean Air technology is an in-car ionization system that helps to purify the air flowing through a vehicle’s climate control system. It works by electrically charging the air with negative ions, which attach to dust, pollen, bacteria, and other contaminates. These negatively charged particulates then attach themselves to a vehicle’s interior air filter, helping to purify the air that flows into the cabin.

What is Hyundai Clean Air?

Hyundai has offered Clean Air ionization for years. More recently, Hyundai introduced an intelligent Smart Air Purification system that monitors interior air quality to filter the air inside a car automatically. The system constantly monitors the car’s air quality, activating the purification function if the air quality decreases below a pre-defined level.

Still, there is always room for improvement, and what Hyundai Clean Air ionization does not currently address is mold that can build up in the climate system and filtration of fine dust particles. To combat those problems, Hyundai has just announced two new technologies designed to improve the quality of air in its vehicles, and one new feature intended to create a more pleasant indoor environment for drivers and passengers alike. 

The new Clean Air technologies are After-Blow, Fine Dust Indicator, and Multi-Air Mode. They will be introduced initially on select Hyundai Motor Group models in Korea and expand to upcoming Hyundai, Kia, and Genesis vehicles worldwide in the future.

If you have ever had to deal with the foul smell of a moldy air conditioning system, you will appreciate Hyundai's After-Blow technology. It uses a dedicated fan to dry any moisture that has condensed on the air conditioning evaporator after the vehicle has been turned off. This suppresses mold growth in the air-conditioning system, which can cause a foul odor, especially during hot weather.

Here's how After Blow technology works. After the vehicle's engine is turned off, the water that condenses on the evaporator is allowed to drain normally for about 30 minutes. Then the After-Blow rotary fan activates for 10 minutes to dry the evaporator and any condensed water that remains in the air passage. The air-conditioning system automatically allows the influx of outside air during this time period to prevent humidity from building up. Without the drying process, the humid conditions in the air passage can foster the growth of mold.

After Blow uses an intelligent battery sensor to monitor battery usage. The sensor keeps the After Blow fan from functioning when the battery is low, stopping full battery discharge that could prevent the car from being started. After Blow also deactivates when the air conditioning system is not in use for a certain period of time or when the ambient temperature is low.

The Fine Dust Indicator tech analyzes the air inside the vehicle in real-time and delivers digitized information to the driver. The indicator displays the concentration of ultra-fine particles inside the vehicle using numbers and colors to enable the user to better understand the significance of each level.

If the level of ultra-fine particles exceeds 36 μg /m3 while the function is active, the air-cleaning mode will automatically activate to purify the air in the vehicle. The air-cleaning system also automatically sets the air volume, switches to air-recirculation mode, and activates the air conditioning system to reduce interior humidity. 

If the air quality does not improve in air-cleaning mode, it serves as a reminder to the driver to replace the air-conditioner filters or to clean contaminated seats and mats.

Hyundai Multi-Air Mode Technology - Find the best Hyundai deals!

The Multi-Air Mode is more comfort-oriented than the other technologies. It employs multiple vents for air conditioning and heating to create a more pleasant indoor environment by diminishing the force of the circulated air in the cabin.

When the mode is activated, air is dispersed to newly added multi-air slots in the driver and passenger seats in addition to the normal air vents. The overall air volume circulating in the cabin remains the same, but because the air is coming from additional sources versus the traditional dashboard vents, the system lessens direct air contact with the passengers and the airflow on occupants feels "softer." 

This mode can be switched on and off based on driver — or passenger — preference.

Especially in this era of social distancing and mask-wearing, consumers are more concerned than ever about what is in the air we breathe. The fact that medical studies indicate enclosed spaces can be breeding grounds of disease is only one reason to pay attention to the quality of the air inside our cars, trucks, vans, and SUVs. 

Do take note, however, that the Korea-based automaker makes no claims that its collective Hyundai Clean Air technologies can combat pathogens like the novel coronavirus that causes COVID-19. 

Rather, these new Hyundai Clean Air technologies build on the automaker’s ongoing efforts to improve in-vehicle air quality, and the company expects the new tech will make the interiors of its vehicles more healthful places to be.
