In-Car Air Pollution

The air inside a car’s cabin can be polluted in three ways:

• Other vehicle emissions can enter through ventilation (PM, NOx, CO, SO2).
• In-cabin pollution (smoking, VOCs off-gassing from cabin materials).
• Bio-aerosols from passengers (pathogens buildup through coughing, sneezing, or breathing).

Car Air Purifiers Checklist:

✓ True HEPA filter air purifier

True HEPA filters are the highest-grade particle filter available in the market. These dense filters are made from fiberglass materials and can trap ultrafine particles effectively.

Additionally, an activated carbon filter layer will help remove gases (odors and VOCs) from the cabin.

✓ Suitable size

Think about where you want to put the air purifier in your car cabin. There are multiple ways you can place a portable air purifier inside your car:

• On the dashboard.
• Inside the cupholder.
• Behind the headrest.
• On the seat.

It will help you pick faster.

✓ Convenient power source

There are mainly three types of car air purifiers based on power source:

• USB-powered: You can power them using a USB car charger with USB A or USB C port.
• 12V Car Power Outlet: You can connect them straight into the 12V car power outlet.
• Battery-powered: No external power is needed. On a single charge, they can run for 4 hours to 8 hours.

Decide which one is most convenient for you.
