How Do Electronic Air Cleaners Work?

There are many different ways to eliminate the pollutants that can circulate through your home’s air and lower its quality. One of the most effective ways to remove tiny particles, such as gas and odor molecules, is with an electronic air purifier. You can combine an electronic air purifier with a filtration system to provide and extra layer of air cleaning for your home. Ask indoor air quality specialists for recommendations on what kind of air purifiers and/or filter will work best for your household.

The basics of electronic air purifiers

There are a few different ways that electronic air purifiers (also known as air cleaners) remove contamination from the air. The most common way is through ionization. Here is how it works:

The air purifier is installed into a home’s HVAC system, where it uses a method called corona discharge to create an intense electrical field. Molecules in the air that passes through this field will either pick up an extra electron, becoming negatively charged, or lose an electron, becoming positively charged. This ionization is more likely to occur to unwanted contaminants because they are larger than the other molecules in the air.

After the molecules have developed a charge, a pair of plates on the air purifier attracts them, one with a negative charge and one with a positive charge. The pollutants drift down to these plates where they become trapped. Many other pollutants of opposite charges are drawn to each other, and the clumping effect makes them heavier than air so they settle.

Although electronic air cleaners are effective at their job, they aren’t always the ideal choice for indoor air quality in a home. Filters sometimes are the more economic option, while UV germicidal lights will help if you have organic pollutants moving through your HVAC system. Let indoor air quality experts guide you toward the best product to clean your air. Leave all the installation work to them as well so that the new system will work exactly as it should.
