ELECTRONIC AIR CLEANER (EAC) INSTALLATION, REPAIRS, MAINTENANCE

Often referred to as ionizers, electronic air cleaners purify the air using electrically-charged filters. As air circulates through your heating and cooling system, electronic air cleaners trap particles and air contaminants to prevent them from re-circulating through your home. Highly effective and easy to maintain with reusable filters that can be washed, EAC’s are excellent choices to maintain clean and healthy air in your home or business.  One criticism of EAC’s is the emission of low levels of ozone, however Harmony opts for brands and models that actually reduce the ozone emitted by other sources in your home.

Viruses are considered organic structures which can interact with (infect) living organisms. Viruses are very small. They typically range from 0.02 to 0.41 microns in size.

Most viruses generally present in droplet form which do not remain airborne for long. A few viruses, (Measles is an example) primarily transmit in aerosol form. That is why they are so contagious. Some viruses that transmit primarily in droplet form can, in certain circumstances, present in aerosol form, making them much more contagious when they do. Viruses presented in aerosol form can remain airborne for up to 2-3 hours.

Droplets do not generally reach an air filter because of the distance, however, having a clean filter with low resistance to flow (pressure drop) increases the propensity of droplets to be directed towards return air systems. A portion of aerosol presentation will reach filters because of the length of time they remain airborne, where they can potentially be stopped.

For a filter to effectively capture viruses it must be capable of stopping and retaining presented particles in the size range of viruses as noted above. At present, HEPA and electronic air cleaners (EAC’s) are the only types of residential filtration products with proven capture capability against elements in these size ranges.

EAC’s are inexpensive and proven to be effective at ultra-small filtration. In addition to being able to capture organic structures like viruses, EAC’s have also been proven to trap other tiny particulate including all types of smoke particles (0.01-1.0 microns) and Radon RDP (0.02-0.4 microns).
