Consider An Electronic Air Cleaner To Help Reduce The Air Particles That Pollute Your HomeAirborne contaminants in your home comes in two main forms: gases and particulates. Electronic air cleaners are helpful in removing aggravating or potentially harmful particles. You can buy small, portable electronic air cleaners to serve a single room, or systems that are installed as part of your HVAC system and clean the air throughout your home.

Most airborne allergens or other contaminants targeted by electronic air cleaners are tiny — 10 microns across or smaller. In fact, particles 1 micron across or smaller make up more than 99 percent of the particles in the air. (For comparison, the eye of a needle is 750 microns wide). These particulates’ tiny size is what lets them remain suspended in the air until they happen to run into a solid surface and stick there.

Electronic air cleaners use “electrostatic attraction” to remove particles from the air. They come in two types:

  • Ion generators emit charged ions into the air. The ions charge the airborne particles by attaching to them. The charged contaminants then either attach to objects in the room or stick together. In the latter case, the weighed-down particles fall to the floor or other surfaces, where they’ll be removed during housecleaning.
  • Electrostatic precipitators also apply electrical charges to airborne particles through ionization. But the ions and the particles remain enclosed in the cleaner, which draws air inside, charges the particles, and then collects them on oppositely charged plates. Homeowners must regular clean the plates to remove the contaminants.

While electronic air cleaners are effective against unwanted airborne particles, they have drawbacks. They do not remove gaseous pollutants. And the process by which they create ionized fields also can create ozone. In combination with chemicals commonly found in homes — air fresheners, cleaning products, paints — ozone can be harmful to some people.
