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.
