Big+ Gravity Water Filter System - High Capacity Countertop Stainless Steel Water Filter Dispenser - IAPMO Certified to Reduce Lead, Total PFAS, Microplastics, Chlorine Taste & Odor

This is a wonderful, simple mechanical water filter that lasts and doesn't come with high maintenance costs. 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.

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.

This is the very best

UPDATE - I returned this and bought a new one directly from the manufacturer with three, 9 inch filters. It takes about three hours to filter a full container now. I don’t think that my previous filter was defective, I think it just takes about 12 hours to cycle through if you are working with just one 7 inch filter. Anyways, I do love this filter, and I hope this information is helpful because there is very little information about flow rates for this filter set up. I did a LOT of research before buying this and it seems like a great water filter system, and the water tastes pretty good. The problem I have is the 7" filter that it comes with is extremely slow. According to the user manual that it comes with, one 7" filter should filter one cycle of water in 4 hours. I cleaned the filter as directed. This is also consistent with other reviewers online. Mine is taking over 12 hours to cycle through, so perhaps I have a defective filter as who knows how long this system has been chilling at the Amazon warehouse. I am returning this and will buy the 3 filter system directly from the manufacturer, hopefully it works better that way.

Water pressure is perfect. At first there was some smell after few days it went away. A bit expensive but works fine. Installation was very easygoing.
