I will never, ever, go back to a tank. I have replaced two reverse osmosis tank systems with WaterDrop active filters. It started by adding one WaterDrop filter at the bar, where we switched to a small-office coffee machine over COVID quarantine that needed a water filter (too many college kids in one house to keep up with a normal coffee maker). It was then that everyone stopped using the kitchen reverse osmosis tank-based water almost entirely and would walk across the house to fill water bottles and cooking pots with the WaterDrop filter head at the bar because there was no reverse osmosis tank to run out. Finally, the boss (my wife), didn't understand why she couldn't fill cooking pots at the kitchen sink because it didn't filter as fast or provide enough water to cook. Instead of servicing the reverse osmosis tank again, I have replaced all our filters with WaterDrop G3. Totally worth the wait.
