Blue future High-tech air filter mechanism

Which form of HEPA filtration? What's the principle?


HEPA filtration divides into 4 types: Interception, gravity, airflow, van der Waals forces


1、The interception mechanism is commonly known as the sieve. Generally, large particles of 0.5μm、10μm are intercepted and "sifted" down.


2、Under the influence of gravity, dust particles with small volume and high density slow down when passing through HEPA, and naturally settle in HEPA just like sediment settling at the bottom of a river。


3、The filter screen is uneven woven lead to become a large number of air swirl.


4、The ultrafine particles hit the HEPA fiber layer in Brownian motion and were purified by van der Waals force. Such as the carriers less than 0.3μm are purified by this force.
