- Employing "Nanofiber bonded textile filter" for the main filter element. Fine fiber collects the dust, pollen and also PM2.5.
- Preventing the virus and mold growth by adding an antibacterial feature to the filter. That helps to maintain a comfortable car interior.
- A layer of activated charcoal helps to absorb the odors. (May be unable to reduce odors entirely.)
- Same size with the stock filter seamless replacement.

What is Nanofiber?
A definition of nanofiber is a substance that has a diameter of 1nm to 100nm and a length of 100 times the diameter.
Nanofiber filters out most of fine particles and microbes due to very small space between individual fibers. A large surface area provides improved absorption. A very small diameter of individual fibers significantly improved airflow by eliminating the vortex generated from fibers in the back.
