About Electronic Air Cleaners
The newer your home is, the less air-infiltration which occurs. Having a tight home is essential for energy-efficiency, but it can result in poor Indoor Air-Quality if air pollutants are not filtered out. According to the U.S. Environmental Protection Agency, Indoor Air-Quality is four to five times worse than outdoor air quality. To achieve and maintain healthy indoor air in a home, it’s critical to constantly clean polluted air.
An electronic air cleaner (EAC) uses electrostatic attraction to trap polluting particles and remove them from the air. The EAC passes air first through a pre-filter, then through an ionizer which gives the particles a positive electric charge. Last, these charged particles pass over metal plates with a negative electric charge running through them. The particles in the air stick to the plates (and are removed from the air).
According to the United States EPA, Electronic air cleaners exhibit high efficiencies in cleaning air due to their ability to remove fine particles.
They are highly effective and offer the following benefits:
- Highly efficient: Most EAC remove 95% or more of the contaminants in air. An inexpensive furnace filter removes about 10%.
- Higher air-quality: An EAC improves Indoor Air-Quality. You can likely expect reduced allergy symptoms.
- Reduced cleaning: An EAC can reduce vacuuming and dusting because it extracts the dust from the air.
- Can save you money: The particles which pass through a furnace air filter can, over time, cover your air conditioner evaporator coil (inside the furnace) and lower the system’s efficiency. This can also be checked and corrected during routine HVAC maintenance.
- They last a long time: EAC are fairly simple machines. As long as you regularly clean their collector-plates, the EAC can run for a long time.
- Maintenance is easy: Most cleaners only need the collector-plates to be cleaned once a month with water and soap. The effectiveness of the air cleaner lowers as the build up of dirt accumulates on the plates

Pollutants affecting Indoor Air Quality fall into 2 categories:
Particulate: Includes dust, smoke, pollen, animal dander, tobacco smoke, and particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses.
Gaseous: Pollutants some of which come from combustion processes. Sources include tobacco smoke, cooking with gas appliances, and vehicle exhaust plus many others. Gaseous pollutants also come from building materials, furnishings, and the use of products such as adhesives, paints, varnishes, cleaning products, and pesticides.
To reduce gases in the air (such as radon, carbon monoxide, ozone and some volatile organic compounds (VOCs) air filters include activated carbon. Today’s residential furnaces can not use an activated carbon filter because it would decrease air-flow too much. This would result in the furnace shutting down due to internal its temperature being too high.
Activated Carbon is a highly porous charcoal product, usually derived from carbon sources such as bituminous coal, wood, or coconut shell. The activation process uses oxygen to open up millions of small pores within the carbon. This significantly increases the carbons’ ability to absorb chemicals as they bond to the large amount of open pore surface within the activated carbon granules.
There are small versions of charcoal air cleaners available. The one shown below is priced at $375 and will service a 750 square foot area. It has a replaceable filter with 6.5 pounds of charcoal to help remove gasses. The product shown can be found at Sharper Image.
If your home has large quantities of gaseous pollutants, these filters are designed to help. Al’s does not sell nor endorse charcoal filters.
