I became concerned as unlike chlorine, chloramines are not filtered, or boiled out.

Good point... From what I understand, even the reverse osmosis membranes don’t take out the chloramines. However, the carbon pre-filters supposedly do although I’ve never seen published values for this. You are reminding me that I need to get a new RO system and this will be one of the things that needs to be checked.
By the way, it was because of chloramines that I’ve given up going to the pool.
There needs to be much more research on chloramines effect upon health.
The same is true of Sorbate as a preservative.
