Electronic Air Filters
Work with your heating or cooling system
The phrase “electronic air filter” refers to an air filter that is run electronically and can be attached to your furnace or air conditioning system. This is not to be confused with “electrostatic air cleaner,” or “electrostatic precipitator,” which refers instead to a type of air cleaner that uses an electric charge to draw particles out of the air.
Electronic air filters work differently from most other types of filters, forming part of your air conditioning or heating system. The air circulating through this system carries millions of particles that are unhealthy for humans to consume and distributes them throughout your home.
How does an electronic air filter work?
There are three steps that must be completed for electronic filters to be successful. First, the air must pass through the pre-filter, which traps most of the large particles. Next, the smaller particles are electrically charged (using an electronic precipitator). Finally, collector plates attract particles and hold them until the cells are removed and the air is clean.
What are the benefits of electronic air filters?
These filters not only remove the unwanted particles from your air, but they do so while still allowing more than enough air to pass through the system. Reduced air flow – a common side effect of other filters – can cause a lower performance rating and may potentially damage your system.
What are the disadvantages of electronic air filters?
There are a couple of minor drawbacks to these filters. First, they require a 120-volt power supply, so you may need to hire an electrician to install an outlet for you. Second, this type of filter will require some duct modifications, which, again, may mean hiring a professional. This could, and probably will, significantly increase the filter's initial cost.
Overall, electronic air filters are very effective in producing the clean air you want in your home, so you may find that even with the added expense, they're worth it.
