What is a HEPA filter?

HEPA essentially stands for “high-efficiency particulate air”  

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?




Large contaminants collide and stick to fiber, getting removed of air body



Particles stick to incoming fibers as it is not nimble and cannot reroute as fast as the air flow



Particles larger than the gap gets trapped as air flows through



Ultrafine particles have more movement than larger particles, hence more likely to  stick to fibers
