RO Water Filtration Systems?

Any recommendations for a reverse osmosis system? I'd need enough water for my plants in a 3'x3' tent, and my wife uses the water for her 4 x tomato plants. I thought I could just keep buying the filtered water from the store, but that's adding up pretty quick, and water is included in my rent, so figured why not get a RO system and save some money.

I've seen some that mention 2-stage filtration while others just say they remove chlorine and sediment. So some of the lingo used is a bit confusing/misleading. A friend of mine suggested getting something from Hydrologic, but figured I'd check with the experts here. Thank you!

If I were to use this system just for my plants. How often do you think I'd have to change out all of the various filters?

Never mind. Found the info on Amazon. Thank you for this recommendation! Looks amazing for the price.
