they sell it with a promise that it will kill 99.9%* of the germs; only for the safety of your family

it is a lie and a false statement,
it is false because you can never kill 99.9% of the germs and if it happened it will be for fraction of a second.
and it is a lie and a misleading sentence because it is not healthy for you and your family to get rid of “the germs”, this is what immunity is, living with your germs!
