OFEN filter that captures ultra-fine particles
 

1. Adhesive (EVA coating) process
  - High-performance static coating
  - Combination of OFEN CMT filter and nano-radiation is what captures the ultra-fine
    particles (PM2.5) by 53%.
  - Excellent durability of nano achieved by heat seal method.
  - Automatic cleaning with rainwater. It can also be conveniently washed by spraying
    shower water.
  - Up to 2-3 years of service life.

2. PET Mesh fabric filter
  - Mesh filter results in higher air permeability compared to dust collection rate.

*Microscopic shot on air pressure experiment (magnified 1,440 times)


• The air was blown with an air gun at a wind pressure of 1 kg / ㎠ for about 10 seconds,
   and then, it was observed under a microscope.
• The original form is maintained with no nanofibers peeled off or removed.

• Nanofibers are removed and the web disappears.

The OFEN filter

EVA adhesive is combined tightly with nanofiber through strong adhesion to ensure air permeability and particulate matter collection.

Maker A's filter

The adhesive for the papermaking in the mesh is applied unevenly and excessively to form a film (poor air permeability).

Maker B's filter

Very poor durability as nanofiber is attached poorly to mesh filter.

• After connecting the hose to the water pipe, the filter surface was cleaned 
  by rubbing it by hand and the surface shape was observed.
• Nanofibers are retained in shape without getting peeled off or removed.
