Coming from an Aquatru (that somehow stopped working after a few months, even after I had replaced every single part), I appreciate the better value and simpler setup. The water comes out tasting pretty good, too. Overall, we prefer the Proone Big+ to the Aquatru. Here's what you should know, though: 1. The system comes with up to three filters (configurable during purchase). The tank is always the same, the point of the filters is that you'll get filtered water at greater speed. How many filters should you start with, you ask? It depends on your family size and consumption. But it's absolutely possible to just start with one, then buy more later if needed. 2. Know that this filtration system is slow. We're using a one-filter setup, and you're getting roughly one drop of water per second and filter. We're a family of seven and get all of our drinking water and most cooking water from this. I'm considering getting a second filter, but for now, we're taken care of. In order to make it work with one filter, we're ignoring the manufacturer recommendation to let the top tank empty into the bottom tank completely before refilling. The only purpose of this recommendation is to avoid overflows of the clean water tank. We haven't had any spills so far, but getting enough filtered water requires regular monitoring of the water levels in both tanks. Without the optional transparent spigot, this requires picking up the tap water tank a few times a day to check both levels. Plus, you have to remember fill up the tank at night to give the system time to filter enough water for the next morning over night. Nevertheless, considering how slowly this filter works, it is really working surprisingly well for us. 3. Before you buy the Big+, consider your tap water supply and the system's height. This filtration system just may not work in some kitchens or settings. It's about 2 feet tall, so it may not fit on some countertops, and it ideally needs its own permanent place in the kitchen (near the sink). And consider how you're going to refill it. You can't just take the tap water tank to the sink like a bucket, because it would drip and you might get the bottom dirty (which is the top of the clean water tank). Rather, you have to fill the system from the top. This works best when your system is located by the sink and you have the kind of faucet that can be extended by 2 feet. In our kitchen, the Big+ is sitting 10 ft from the sink, and we're using large thermos bottles or cook pots to refill it. Which is working fine for our purposes, but it's something you should be aware of. Review: Happy with this investment - Ive been pretty happy with this purchase! There were a few issues in the beginning with leaking and slow filtering, but it has been great since then (1.5 years). I wish the filters were not so expensive, but I am happy with the clean water taste. Thankfully 1 filter lasts me about 9 months. ## Features - WATER FILTER DISPENSER: With so many chemicals and contaminants out there, everyone needs a reliable water filtration system.

After scrubbing your filters, cycle 3 batches of water through them and dump the water. Start drinking your water on the fourth cycle for the best taste. **Q: How do I prep my ProOne gravity system for travel?** A: Allow your filter elements to dry out, then wrap them in a cloth and store them in a safe place. If you store filter(s) inside the gravity system, make sure they have ample padding to prevent breakage. **Q: How often should I clean my gravity systems and filters?** A: We recommend cleaning your systems and filters at least once a month. **Q: When and how should I store my filters?** A: If you are not using your filters or system for more than 4–7 days, drain the water and air-dry the filters. Wrap the filters in a terry cloth towel and store them in a cool, dry place. Do NOT put them in a plastic bag or any enclosed container. **Q: How many filters should I use?** A: Each ProOne G2.0 filter has a general lifespan of up to 6 months with daily use. Using more filters at a time will increase their lifespan and flow rate at the same time. Using 3 filters at a time will provide the fastest flow rate. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Outstanding water filter - with some caveats *by B***M on 10 February 2024* This is a wonderful, simple mechanical water filter that lasts and doesn't come with high maintenance costs.
