What's the best way to do RODI in an apartment?

[sewerman45]

I have a 47 gallon tank that I finally have all plumbed and ready to go. I need to figure out the best way to do water. Is there some kind of RODI unit that doesn't need to be plumbed in? Are those tap filters decent? Something like this?

Any tips or suggestions this way would be great! Thanks.
