Among all advantages of portable HEPA filter, there is one point I have to mention. Portable HEPA Filter is usually very quiet. That's due to its advanced working principle. As for how portable Air Cleaner work, well, contrary to popular opinion, they do not work like membrane filters, allowing only particles that fit through the smallest openings to come through. Instead, portable HEPA filters, targeting particles at the microscopic level, work by trapping or getting to pollutants to “stick” to the special fibers (which are stacked in layers) in one of three possible ways: diffusion, impaction, and interception. Each of these processes involves complicated microscopic particle motion physics. It should suffice to say that portable HEPA filters act more like magnets than sieves or colanders. That's the second advantage of portable HEPA filter.
