Copper or stainless steel would probably be the best choices for the cleanest water, but if you're just watering plants, steel pipes would probably work well enough.

At its simpliest an air well is a structure or a device that collects water from the air using condensation. In the early part of the 1900, a few enterprising men experimented with rock air wells to capture moisture. They were working off the theory ancient cities used stacks of rocks as condensers and terra cotta pipes connected to the city’s water system to supply water for the city.

But if, for example, there was a layer of biochar that the condensate ran through, and/or filtration through sand layers, or depending on the specific situation perhaps a swale system heavily planted with reed species and other water cleaning aquatic plants, any of these steps could be used to clean the condensate.
Figures we'd be looking to stone-age technology to solve modern-day calamity.

This will take every ounce of my mental strength! All for a tiny ad:
