Considering you’re exposed to water during limited times (and need to actually ingest it) but exposed to air 24/7 (or else you die) that doesn’t seem like a reasonable comparison.

If someone standing in front of you sneezes, a filter in the HVAC isn’t doing anything to stop you from getting covid.

I mean, isn’t airborne transmission still uncertain for Covid?

We don't have to eliminate all transmission to stop Covid, we just need to bring the R value below 1 and keep it there. I don't think that direct transmission via sneezing is a significant cause of spread, but sneezed particles could remain in the air for a long time, long enough for a filter to make a difference.

I don't think there's any uncertainty left in airborne transmission: https://www.forbes.com/sites/jvchamary/2021/05/04/who-corona...
