What is the difference between air scrubbers and air purifiers?

Air purifiers are typically portable units that filter the air in a single room, using a fan and a filter to trap airborne particles like dust, allergens, and smoke. Air scrubbers, on the other hand, are whole-home systems installed directly into your HVAC system. They actively neutralize pollutants—not just in the air, but on surfaces too—using advanced technologies like UV light or ionization.
