I found this too. I wonder why they don't just accept a PUR water filter on the input side.

I also wonder why mini-split heating systems drip and pool water outdoors instead of pumping that distilled water back indoors for humidification.

It's funny in an ironic way because the original purpose of air conditioners was to remove humidity from the air, the mechanism used was to cool the air down thus forcing some of the moisture out. The general public quickly caught on that having cool air was nice in it's own right and that is the main purpose these days. however the dehumidifying function is still sometimes used, people are surprised when their air conditioner turns on at the same time as the heater (why are they fighting each other?) but that is because the system is trying to remove moisture from the air before it is heated. Mainly seen in cars so the windows don't fog up.

Probably something wrong with me but I just find it humorous trying to add moisture to a system designed to remove it. Really a reasonable request however, depending on where you live the air can get quite dry.

You’d need a reverse osmosis system, not just he charcoal filters like that

And the condensate water from an AC evaporator coil is not anything like distilled water, dust/bacteria are also in it.

Do you want Legionnaire's Disease? Because that's how you get Legionnaire's Disease.

During summer dehumidification is needed in most areas.

And it is really not distilled water. It gathers dust and so on from air. Distilling in more so closed circuit, where as those are very much open.
