Theres no way for me owning a ro/di filter so i wanna no if theres anything else i can use to purify my water

[NCreefwannabe]

not really... Buying distilled is about the only other way.

Why is there no way to own it? buying distilled will cost more after about a few months anyways.

Around where I live, there are some stores that sell highly-purified water (they use RO-DI and carbon). You might be able to find a similar source.
