I just finished making a DIY atmospheric water generator and it works very well. I bought a new Kolin KDM-18 dehumidifier I then took off covers and rinse it thoroughly with clean water. I wiped it and dried it with lint free clothes.
I installed a 1/2 inch hose and ran the water into a 6 stage filter system. First a ceramic filter, then a silver carbon filter, then a WSM-300 antibac filter, then a Silica sand filter, then a Zeolite filter, and then a mineral sand filter.
I am thinking about adding a UV lamp to the storage area.
The system produces about 18liters a day
The water before the filters is 7.0pH after the filter it is 8.0pH.
All in all I the cost was around $450 and cost about 6cents US per hour to operate.
