1 part H2O2 to 50 parts water? How can that be very effective? (I passed chemistry with a B, but only because the final was multiple choice. Plus a lot of homework and prayers.)
You can diffuse straight 3% hydrogen peroxide right out of the bottle — but that may cause slight eye irritation, and so you can titrate until you find the right dilution that works for you.
I will admit that 1:50 is on the weaker end of the spectrum of effectiveness — but I notice at that weak dilution — mold and mildew doesn’t grow on my evaporative air cooler filters — which is a problem using straight tap water.
It’s a great opportunity to learn on your own by actually doing these experiments — and seeing if it works for you. But to say “right” or “wrong” because you got a B in chemistry doesn’t mean much. Most of the greatest discoveries in science and research were made accidentally, and not because one got an A in their subject matter and therefore knew all that there was to know.
That’s Fauci territory.
