CleanSweep® AC EMI filters provide effective noise reduction where it matters - in your environment.  Many generic EMI suppression filters work well only in EMC test labs but do little or even can boost EMI in real-life installations (see here why).   CleanSweep® patented power line noise filters block EMI on real life power lines (both common mode and differential mode) and, uniquely, in ground, from reaching your sensitive equipment.  They also reduce EMI "backflow" from a "noisy" source that otherwise would end up on your AC power network.  

In addition to be highly effective in reducing EMI, CleanSweep® AC filters also offer advanced transient surge protection unachievable by regular MOV-based surge protectors - see some of the performance data further on this page. 

CleanSweep® filters are plug-and-play and can be installed in minutes without the need for an electrician.

EMC "EG" Filters to Reduce EMI from Equipment

Soldering Filter to Reduce Tip Current and EOS

When selecting filters by current rating, we recommend to leave some headroom for unexpected current surges and spikes: often rated current consumption for equipment does not take into account occasional overcurrent peaks which may cause filter's circuit breaker to trip and to cut off power to your equipment.  For example, use 10A filter with equipment rated no more than 8A just in case of such overcurrents.  

All CleanSweep® filters perform equally well in all aspects - the difference is only in current rating and physical size.

CleanSweep® EMI Filters offer unparalleled performance in actual use

CleanSweep® filters protect against transients

CleanSweep® power line EMI filters are available in many worldwide configurations, as well in hospital/medical grade and with different mounting options - see below for details.

Did you know that most regular EMI filters are effective only in the test lab but may amplify EMI in actual installations? Yes, it is in their specification.  Real-life installations have long cables, multitude of EMI sources, "dirty" ground, and power line complex impedance that have nothing to do with the "sterile" 50 Ohms found in the test labs. 

OnFILTER' CleanSweep® AC power line EMI filters are designed to be very effective in actual installations (they do well in the test lab too).

CleanSweep® filters offer advanced transient surge protection unachievable by regular MOV-based equipment. CleanSweep® filters treat transients as EMI reducing them to harmless levels. Regular surge protectors allow spikes up to 700V to get to your equipment. Plus, they don't deteriorate as MOVs do.
