Air purifiers remove particles from the air based on their efficiency rating. This means that a HEPA rated system with an efficiency of 99.97% at 0.3 microns or better will remove all larger and smaller particles from the air, essentially rendering the air dust free.
People with asthma and allergies will find great relief. Air purifiers designed with those conditions in mind can remove nearly all the symptom causing particles from the air. That means people who suffer from those conditions can be at ease and breathe clean air in their home or office.
