## Description

General purpose single phase AC power line filters, easy to install. Available for small electronic equipment's and measuring in instrument.

Review: Great AC line filter for Arcade Cabinet - I use these AC line filters as a pre filter before my switching power supply when I’m redoing the wiring for arcade cabinets. They work great and are easy to use. The ground terminal is a little close to one of the AC terminals so just make sure you don’t have any stray wires. Other than that these work perfectly and I recommend purchasing them.
Review: CNC Noise filter - Connected to a CNC to reduce noise and it seems to work. Based on real world use I would buy this again. Before had some background noise that limited speed - just a little - but still this appears to solve a nagging issue.

### ⭐⭐⭐⭐⭐ Great AC line filter for Arcade Cabinet

### ⭐⭐⭐⭐⭐ CNC Noise filter

### ⭐⭐⭐⭐⭐ Clean power
*by R***. on December 11, 2025*

Cleaned up the 120 volt input to my Arduino project. No more random resets and code lockups. The ground lug which must be grounded is very close to the hot power terminals. Beware of shorting out the unit. Will buy again for future Arduino projects.
