Easy to install and highly effective, it’s a must-have for professionals seeking clean, reliable power. ## Description General purpose single phase AC power line filters, easy to install. Available for small electronic equipment's and measuring in instrument. Review: Clean power - 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. 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. ## Features - Product Name : AC Power Line EMI Filter;Model No. : CW4L2-20A-S - Working Voltage : AC 115/250V, 50/60Hz;Rated Current : 20A - Installing Hole Size(Approx) : Distance: 7.5cm / 3"Diameter: 5mm/0.2";Size(Approx) : 6 x 5.5 x 3cm / 2.4" x 2.2" x 1.2"(L* W*H) - External Material : Metal;Color : Silver Tone, Black - Net Weight : 176g;Package Content : 1 x AC Power Line EMI Filter ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 135 Reviews | ## Images ![Uxcell AC 115/250V 20A CW4L2-20A-S Noise Suppressor Power EMI Filter - Image 1](https://m.media-amazon.com/images/I/6164UlhpJ7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Clean power *by R***. on December 11, 2025* Cleaned up the 120 volt input to my Arduino project.

Had a lot of RFI from an inverter generator interfering with my radio equipment. This fixed it. It does need to be grounded to work effectively though. ## Frequently Bought Together - Uxcell AC 115/250V 20A CW4L2-20A-S Noise Suppressor Power EMI Filter - Tamicy 60 Pieces Clip-on Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip for 3mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter/Video Cable Power Cord (Black) - 20Pcs Clip-on Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip for 3mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter Cable, Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/28665957-uxcell-ac-115-250v-20a-cw4l2-20a-s-noise-suppressor](https://www.desertcart.sn/products/28665957-uxcell-ac-115-250v-20a-cw4l2-20a-s-noise-suppressor) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-07*
