What is a HEPA filter?

HEPA essentially stands for “high-efficiency particulate air”  

HEPA filters are designed to be able to filter 99.97% of air pollutants in the air, up to 0.3 microns.

What are HEPA filters made of?

Modern true HEPA filters are made of interlaced glass fibers that are mazed and twisted to form a fine mesh.

Cosmo’s specially engineered HEPA Filters have pores that are up to 20 times finer than the average HEPA filters.

How do HEPA Filters work?

 

DIRECT IMPACTION

 

Large contaminants collide and adhere to in-built fiber molecules, thereby removing contaminants from surrounding air.

INTERCEPTION

 

Incoming pollutant particles are trapped as a result of being unable to permeate the fine mesh structure of HEPA filters. 

SIEVING

 

As the pollutant particles remain impermeable, clean air flows through the fine mesh structure.

DIFFUSION

 

Even ultra-fine particles adhere to the filter’s fibre molecules due to its constant random movement and high kinetic energy.
