The Hum-AC 820 that I have seems identical to the Surf-AC
We do not carry the Hum-AC 820 but do see on the manufacturers website that it has a different active ingredient than the Surf-Ac 820 Non-Ionic Surfactant so they are not the same. Hum appears to have Glycerol, alcohol ethoxylate, polyoxyethylenepolyoxypropylene monobutyl ether, Surf-Ac is just Alcohol ethoxylate, alkylphenol ethoxylate.
