if you get an RO set up make sure you can change the osmosis membrane yourself.
the osmosis membrane is kind of the main deal. there are usually a couple other filters as well.
some manufacturers encase the membrane in a proprietary cartridge. forcing you to buy their brand at a premium price, until they change the design -- and force you into an expensive upgrade.
the membrane and individual filters, are all available as cheap generics. if you chose carefully and buy with prudence.
