Are there any EPA tested/approved HHO kits available for sale?

Question

If so, provide a link and/or other form of proof.

Answer 1

no

Answer 2

No, and there never will be, because these are scams.

The only scientific evidence I could find to support the claims that hydrogen can enhance the combustion of more complex hydrocarbons in an internal combustion engine indicated that the level of particulates in the exhaust actually *increased* and even the HHO scammers often recommend that you *remove* your HHO system before you submit your car for its emission test - because the NOx levels go through the roof.

To find out more about the scam and why these kits at best, simply don't work and at worst, can cause burnt valves and major engine damage, visit the links below.
