That's some crappy RO water. My home system takes 45 ppm water and reduces it to <2 ppm (~500 kΩ). For all intents and purposes, it's not conductive on its own.

Distilled water is made by steam condensation, and nearly ultra-pure but still contains dissolved gases.

DI water should be made from some distilled water to be the highest possible purity, but it's usually made from RO or simply filtered tap water.

There are some things DI can do that steam distillation can't, and vice-versa. The two processes are entirely different and NOT interchangeable.

Ok, I modified my original comment.

My tap water is around 227 and filter is just recently installed, there's still some air in the system. I don't think it will go that low ever, but it's good enough for me. I plan to remineralize it a bit for drinking anyway, so it's all a bit moot.

Filters and RO systems rarely remove dissolved gases. Try making ice from RO water vs. lab DI water.

I don't need it to remove air from water, I need it to stop mixing air that was in the empty spaces around filters when they were installed into said water. Tap water doesn't have much air in it I don't think, it will sort itself out eventually. Right now I have very small air bubbles that are still visible when filling up a glass, they are created when air and water pass through RO membrane. After you let it sit for a while PPM number drops.
