The objective of this work was to test a number of commercially available whole-house filters under different line noise conditions,
such as solar inverters, pool pumps, AC and heating systems with variable speed motors, lighting, grid noise, etc. The data was collected
at multiple sites in different states by different people, all using the same equipment. Additional testing has been performed using
combinations of filters, and will be presented here when available in a suitable display format. The documents below are PDFs and will
open in a separate window.
