Hello,
The Puritan PSM156 or PSM136 will do this. It filters out over the air signals like WiFi, cellular, and Bluetooth. It also filters out noises from DC, compressors, and switch mode power supplies. It is incredible. If you are in the Chicagoland area this store lets you try before you buy. https://holmaudio.com/
They also have the Guardian power plug filter.
