Vacuum cleaners only labeled "HEPA" could possibly have a HEPA filter, but not all air necessarily passes as a result of it. Last but not least, vacuum cleaner filters marketed as "HEPA-like" will commonly utilize a filter of the same construction to HEPA, but without the filtering efficiency. Due to further density of a real HEPA filter, HEPA vacuum cleaners need a lot more strong motors to offer ample cleaning electrical power.[citation desired]
is the mechanism by which mid-size particles that aren't large ample to have website inertia but not small enough to diffuse Stick to the air stream mainly because it curves and bends through the fiber spaces. The particulates are then trapped when they collide with the fibers.
