International Filter


Greenwave’s Spectrum 2400G filter is currently available for use outside the U.S. and Canada.

These filters are compatible with 50/60-Hz AC electrical systems with voltage up to 240V. They come with a 3-prong North American plug, but can be used with plug adapters (not included with purchase).

No voltage adapter is required. The filters are UL approved for the U.S. and Canada (AC120V, 15A) and are RoHS compliant. They do not include a built-in outlet. They are built to work up to 240 volt.

Thousands sold.

The filters can be purchased individually based on your specific needs.

Greenwave filters significantly reduce the amount of DIRTY ELECTRICITY (a.k.a., electrical noise, line noise, EMI) present on the wiring in buildings. This is the most direct, effective, and practical way to clean up this type of electro-pollution. The less dirty electricity there is flowing along building wires, the less that will radiate into your environment. The filters plug directly into electrical outlets and power strips. They deploy state-of- the-art EMI filtering technology to “short out” (or shunt) erratic surges and spikes of electrical energy (i.e., dirty electricity), while allowing standard electricity to pass through the filters unimpeded.

How Many Filters Do You Need?

For best results, we recommend installing Greenwave filters throughout your environment. The number of filters needed will depend on the size of the building or space where you want to install them (e.g., # of rooms) and on the concentration of electronics, appliances, energy-efficient lights, and other electrical devices in each room.

Here are some general guidelines to help estimate your filter needs.

Home Environments:

This chart shows the number of filters typically needed for most rooms within homes. You can use this chart to help estimate the number of filters you may need for your home.

Type of Room Number of Filters Typically Needed
Kitchen Family Room Living Room Media Room Home Office 3 – 4 filters (each)
Bedroom Dining Room Laundry Room 2 filters (each)
Bathroom Walk-in Closet 1 filter (each)
Basement Garage Tool Shed/Workshop 1 – 2 filters for every 150 square feet


5 filters per classroom

Business Settings:

2 to 3 filters per 100 square feet

Please keep in mind that these are estimates and provide a good starting place for thinking about the number of filters you will need. The best way to determine the optimal number of filters to install is to use a dirty electricity meter to guide installation.


The price charged per filter will depend on the total number of filters ordered.

1 – 7 filters: $30 per filter

8 or more filters: $28 per filter

Measuring Results

The effectiveness of the filters can be measured using Greenwave’s Broadband EMI Meter. Simply plug the meter into electrical outlets to measure the amount of dirty electricity on nearby wiring before and after installing filters. The meter is also an excellent tool for guiding the installation of Greenwave filters. It can help you identify significant sources of dirty electricity in your environment and determine the best number of filters to install in each room for optimal results.
