Why must you keep arguing? Is it the AC current in your walls, or all the rotting ingredients in your fridge?

…additional thought for product safety. Select the manufacturing manager to be someone who likes the product. Get him to consume enough of every fresh batch. If he gets sick, recall the batch.
This couples the incentive to manufacture the thing well with a bioassay of every batch.
Random thought. The conversion to DC may be pretty useful for places with not many other dwellings in the vicinity. Would require banishing things like synchronous motors, transformers, and inductive ballasts from one’s equipment. Essentially, if there’s ferrite core inside, good; if there is a laminated steel core, and it is not a brushless motor, bad.
Would give the benefits of using a raw battery stack as a backup system (simplifying the UPS down to merely a charging circuitry, so a wreck of an electric car could be repurposed for that). Would also give the advantage of not having the AC hum all around, which, while not a problem for people, is a major annoyance for measuring instruments and sound recording and biomedical measurements.
Getting totally off mains is impractical, but getting off AC can be useful in some situations. There’d have to be quite a lot of filtering equipment on the DC line to get rid of the hum that goes through the charger (though the AC line can be disconnected for a while, thanks to the batteries, if even lower levels of noise are desired), and the location of the site would have to be somewhat distant from dense civilization and overhead wires, to avoid coupling via radiated emissions and magnetic fields…

Just like an engineer to ruin a good joke by pointing out how it could be done!
