Electronic Air Cleaners, Pros & Cons
An eac can remove small particles but cannot remove gases or odors. They can remove these very fine
particles without significantly reducing the air flow through the hvac system. For example, they will
remove the small particles in tobacco smoke but the smell and gases will remain in the air.
Also, these units require monthly maintenance. This includes removing the pre-filters and cells and
washing them. Most of them can simply be put in a dishwasher to be cleaned.
**HOT TIP** Do not run them through the dry cycle in the dishwasher as this can cause
possible damage. It is better to let them simply air dry.
Keep in mind that, if the blower on the hvac system is not running, these units do nothing. Therefore,
to get the full benefit, the blower must run continuously. This will raise your electric bill. This
increase can be minimized with a variable speed fan motor.
They also make a popping noise when particles are trapped.
Lastly, they are pretty expensive (~$500) to install.
