seemed like a good deal until I discovered it costs $200 for replacement filters.

Not to mention that 50% of the water used literally goes down the drain.

I hate the idea of how much waste it would be, but if filters cost $200 and this comes with filters.... need I say more? It's no more waste than if they didn't sell and just sat in a warehouse till oblivion.
