What is an ultra high efficiency air filter?
When the cleanliness requirements of your level 10, you must choose the ultra efficient filter (U15), if it is 100, using high efficiency filter (H14) is enough, if only to filter haze, which is the 2.5UM particles, with the effect is enough.
In fact, the filter is equivalent to a sieve, different aperture can pass through the particles are different, so the choice of HEPA filter, only the right is the best.
At the beginning of the effect is greater than or equal to 5UM of the FAE particle filtering effect, filter dust particles is greater than or equal to 1UM, high efficiency refers to filter dust particles is greater than equal to 0.3um or 0.5um, ultra performance refers to filter dust particles is greater than or equal to 0.12UM.
The classification of air filters is primary, medium, efficient and ultra efficien
