Air ionizers clean the air in your home using the natural chemical properties of ions. These machines use electricity to create negative ions and then release them into the air. The negatively-charged ions naturally connect to dust, pollen, bacteria, smoke, and other positively-charged particles in the room. The particles then can be sucked into the unit’s filter, fall to the floor to be vacuumed, or attach themselves to surfaces in the room where they can be removed through dusting. When looking for an air ionizer, you’ll need to consider the size of your room and whether or not you would like to move it between rooms. Think about preferences for reusable or replaceable filters, UV lights to kill airborne bacteria, and options for ozone production.
