CleanSweep® AC EMI filters provide effective noise attenuation where it matters - in your environment. Many generic EMI 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 EMI filters block electrical noise 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 entire AC power network.
EMI of EMC Filters?
EMC, or electromagnetic compliance filters, reduce electrical noise generated by a particular equipment so that it can pass EMC regulations for compliance.
EMI, or electromagnetic interference filters, block noise on power lines and ground from reaching your sensitive equipment.
See Selection Guide for the best filter for you.
In addition to be highly effective in reducing EMI, CleanSweep® AC EMI 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. Most filters have option for terminal blocks for wired installation, as well as option for mounting brackets for fastening them for permanent installation.
"Just a quick note to say thank you for the noise filter. The filter has proven to be completely effective in eliminating any of the issues I was experiencing. Thanks again for the excellent filter" (R.B., Canada)
"Certainly, using one of OnFILTER’s CleanSweep filters would work well to reduce or eliminate transient EMI contaminating power lines from things like soldering stations or industrial machines using servo or variable speed drives"
Ken Wyatt - see review in EDN Magazine.
We compared the AP Series 3A AC EMI Filter and the TrippLite power conditioner and the Furman AC-215A. he AP Series 3A AC EMI Filter was the only one that eliminated the effects of the IEC test (Electrical Fast Transients and Bursts) on the device under test. Congrats

Questions? Ask Us
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 in physical size.
Examples of Applications
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.
Hospital/Medical Grade Option
Hospital / Medical grade options for some filters simply means low leakage current and, where available, special cables and outlets - acceptable for non-critical applications in medical environment. Note that these types of filters do not perform any better than the regular filters - their common mode noise rejection is actually slightly worse due to lower leakage current requirements.
Default mounting for CleanSweep® filters is rubber feet. Some types of filters can be equipped with the mounting flanges if you need to fasten the filters in specific location.
It is a good idea to check with us whether
this option is available for the filter of
your choice. If it is, add "K" to the part
