Cars are made of metal, which amplifies EMF challenges. Whether you spend a lot of time in the car or run a few errands around town, I recommend a Car Harmonizer.
 
A single Car Harmonizer remidiates gas powered cars and hybrid cars. Fully electric cars need 2 Car Harmonizers if there are enough outlets.
 
The Better ZZZ's product can be used as a substitue for a 2nd Car Harmonizer if there are not enough outlets.
