@muon which blog? People have varying opinions according to risk level tolerance. If it was on lung matters I've noticed they have zero tolerance for alternatives to boiling. They boil everything -- drinking water, all devices after each and every use. They do not trust any spigot, even if it has been tested. They show setups with dedicated water boilers/sterilizers, usually the instapot. There's certainly something to be said for zero tolerance if it sets your mind at ease.

Instructions with aerobika say microwave steam bags are ok. I boil my devices once a week, and will replace twice a year. No NTM diagnosis so far. If I were getting repeated infections I might consider a zero tolerance plan. It does make sense to be careful, how much varies.
