What is the difference between electronic and media air cleaners?
The two primary types of Whole House Air Cleaners are the Electronic type and Mechanical or Media type. Both have good features and benefits. Which one is right for your home depends upon your individual needs and your equipment type and configuration. An electronic air cleaner uses an electrical field to charge small particles in the air as they pass through the filter. Once the particles are charged, they then pass through a collector grid with the opposite polar charge. This makes the dust and small particles stick to the collector like a magnet. Electronic units usually have a pre-filter to catch the larger particles before they enter the charging field. These filters have an excellent capture rate if they are properly sized, installed and maintained. They do not require filter replacement, but they do require regular maintenance. The collection efficiency falls as the collection plates become coated with dust. The pre-filters and collection cells need to be removed and cleaned reg
