HEPAThe filter may remove at least 99% airborne particles 0.3 micrometers (m) in diameter. The size particles are the most difficult to filter and are believed to be the most permeable particle size (MPPS). Larger particles or smaller filters with high efficiency.
Activated carbonAir purification principle is by relying on its own developed carbon pore structure and surface area, can greatly exposed to ambient air pollutants, some passive adsorption to their pores, so that the surface of the activated carbon is more developed pore structure, adsorption capacity is stronger. Similar materials similar to bamboo charcoal, charcoal, nano living ore, etc., can be used to absorb formaldehyde, TVOC, benzene and other harmful gases.
The HEPA filter consists of an arbitrarily arranged fiber mat. The key metric affecting the effect is fiber density and diameter and filter thickness. The airspace between the HEPA filter fibers is larger than 0.3 M. The common assumption is that the HEPA filter acts like a a sieve, where particles are smaller than the maximum beginning and may pass incorrectly. As for the membrane filter particles, they are as wide as the largest opening or distance between fibers, which is impossible to pass through between them. But the HEPA filter is designed to aim at smaller pollutants, and the particles are trapped mainly by one of the following three mechanisms (they stick to the fiber):
Intercept particles engage in streamlines in the air stream coming within a radius of fiber and following its place. The particle impaction more cannot bend by following the air stream high places to avoid a direct buried fiber and forced in their home; the flow speed and the higher the increase to reduce the fiber separation. An improved diffusion mechanism is the result of collisions with the gas molecules from the smallest particles, especially those in the diameter less than 0.1 M, and in their path to interfere and delay through the filter; this behavior is similar to the Scotland botanist RobertBrown action and possibility of training the particles will pass by one of the two mechanisms above it becomes; rule in lower air velocity. Diffusion is predominant under the size of 0.1 m diameter particles. In the above 0.4 impaction and interception of the dominance of M. Between 0.3 and mMPPS, diffusion and interception dominate.
