Cleaning and Effectiveness | How Electronic Air Cleaners Work
The location of the EAC is in the return air ductwork. It is upstream of the cooling coil and the air handler in the air stream. Additionally, as air moves through the return duct (usually at a central point of the regular filter location), it moves through the return duct towards the cooling coil and air handler. This air contains dust particles and volatile organic compounds. Furthermore, particles too small to be caught up in the regular filter and the electronic air cleaners pre-filter are pulled into electronic air cleaner where they pass across ionizing wires.
Depending on the model and manufacturer depends on if the ionizing wires have a negative charge or a positive charge. After the ionizing wires are collector plates with an opposite electrical charge as the ionizing wires. Furthermore, the particles are given an opposite charge as the collector plates, which cause the particles to be automatically attracted to the oppositely charged collector plates. Lastly, some manufacturers claim that their electronic air cleaners filter particles down to one micron.

Honeywell is probably the most recognized name for electronic air cleaners. The Honeywell F300 fits into the ductwork upstream from the air handler and removes up to 99% of particles in the air. It has a pref-filter, the electronic air cleaner cells, and a post-filter giving it three stages of filtering for eliminating duct particles. Honeywell claims the F300 will filter dust particles and other particulates down to 10 microns. How small are 10 microns? Quoting Honeywell, the dot in “i” in micron is about 400 microns, so 10 microns is pretty small. Furthermore, for extra protection and a proven method to kill viruses, bacteria and mold use the Honeywell ultra-violet air cleaner in conjunction with the Honeywell EAC.

UVC Light to Kill Viruses and Other Airborne Harmful Things that Affect Health
For additional protection you can also use a UV Light that will kill harmful viruses and bacteria inside the airflow of the air handler. In labs researchers used a spectrum of ultraviolet light called UVC to kill viruses. This product requires professional installation so it will turn on and off with the blower fan in your air handler but it will offer the protection you need for you and your family from any viruses.

The Aprilaire EAC works much the same way the Honeywell works described above. When its time to clean the filter, you pop it out, wash it using recommended methods, and replace it. Simple as that, except don’t forget to turn the power off before removing the filtering media.
Conclusion | How Electronic Air Cleaners Work
There are also HVAC brands like Carrier, Lennox, and Trane that produce their very own EAC systems. I always recommend electronic air cleaners with ultraviolet air cleaners. That, along with your typical off the shelf air filters for the best indoor air quality. Having good filtering media removes many things from the air that are invisible to you. Additionally, they also remove some odors from the air. While these systems don’t remove everything from the air, they are much better than just having a single filtering media in your HVAC system.
Remember to keep your EAC freshly maintained with clean filtering cells. Additionally, electronic air cleaner studies have shown that the dirtier the collector plates become the less effective as they are at collecting small particles. Finally, it is important to properly maintain your electronic air cleaner. Maintained on a regular maintenance schedule so that it will filter the air effectively.
