Fortunately I don't need to filter my water, tap water quality in my country is one of the best in the world (so much so that Kikkoman built their European soy sauce factory here in the Netherlands specifically because of the high water quality). I only filter water for my espresso machine to prevent scale buildup. Never tried boiling water for tea on my induction top, smallest size is 12cm (4.7") and the power setting delivers 3680W so it should be very quick, but still not as quick as just having instant boiling water on tap.
Instead of a mug, you could try a small induction compatible kettle or just get a cheap electric kettle. You can easily find a >3000W kettle for less than €50.
