My mostly on my gut feeling based counter argument would be:
So what? You are cooking the water afterwards cross-contamination between water samples isn’t a huge deal. Additionally, Filters (especially things like cloth) are cleanable and potentially sterilisable via cooking.
cooking is a violent process, grinding down particles, lessening the effectiveness of the filter. So you are potentially worse off, for no real gain.
You can’t always cook. Sometimes you have to sterilise water another way. E.g. via exposure to as much UV/Sunlight as possible. Particles in the water lessen the effect or prevent this from happening
Wouldn’t boiling first be better so you don’t end up with a bacteria colony in your filter?
