CAN someone recommend a quality RO filter

i live in a poor country in europe so i have to order almost everything online now im planing a new growroom in hydro so can somebody recommend a good quality RO filter manufacturer cause i dont know much about that and i have no one to ask

anybody using a RO filter

any cheap $150US system on ebay will work just fine,they are all basically the same thing except more expensive units remove more particles because of how many stages a particular system runs.hope this helps,oh,a 5 stage filter should do u right,peace out

thanks for the advice i cant shop on ebay,if someone has a ro filter or knows name of a reputable manufacturer
