Is there food safe plastics that don’t leach microplastics? My RO filter uses plastic tubing, I imagine within the filters themselves there’s plastic
The main source of microplastics in water bottles isn't the bottle that's the filters (and the residual amount in the bottle is pretty astonishing)

Otherwise I would recommend a good plastic RO system. One where the plastic doesn't leach loads of harmful plasticizers.
(And your comment on taste is interesting. Distilled water doesn't taste like anything (except possibly slight tingling if it "burns" your tongue), which is why minerals are often added to drinking water to make it taste "good")
I find the water from my still tastes actually really good. It's silky smooth, nothing like distilled water that's been sitting in a gross plastic jug for weeks.
So I'm not at all concerned there is any risk at all.
It's not about nutritional intake, but the acute effects of ingesting it. If you put cells in distilled water, the cells absorb water due to osmosis and rupture. There may be some minor risk of chronic damage accumulated to the upper digestive tract (though I'm not an expert).

Does it actually taste, or do you just enjoy not having a taste? If it has a taste, it is not entirely distilled; there are residual minerals and substances in it (which negate the potential risks of drinking it, at least from the previous point). However, that kind of defeats the "distilled" aspect of it...

As to the taste, I guess it's more fair to say it's got a very silky mouth feel, but no taste.
