NanoFIL Inside

When you see the label of ‘ NanoFIL Inside ’ on an air purifier, you know that you can breathe freely without worry on the Indoor Air Quality (IAQ) inside the space you locate.

Our patented sterilizing nano filter is definitely the key component of an air purifier or air conditioner that improve the performance (the capability of filtering out contaminants such as dander, dust, bacteria, viruses, harmful gases and so on) of the purifier or appliances that have the feature of air purification, also can exterminate over 99% of Coronavirus (COVID-19 Omicron variant), 99.99% of bacteria and virus of a wide spectrum. This is the image that NanoFIL strives to build in the minds of its customers.

Our technologies

NFFT applied electrospinning technology to air filtration materials that produce nanofiber filter media. Nanofiber filter media has the characteristics of high porosity, small fiber diameter and aperture. It can achieve high mechanical filtration efficiency, high dust loading capacity and low pressure drop.

NanoFil Filter media

  •  Nanofiber is our core technology featuring filtration, antibacterial, antiviral and other specific functions.
  • Non-woven fabric, such as PP and PET, which are polymer materials.
  • Activated Carbon is combined with hydrated aluminosilicate minerals to remove odour, formaldehyde and VOCs (Volatile Organic Compounds), etc.
