Quality Gravity Water Filter Tank and Affordable!
So far, so good! We live in east central Texas and our water is horrible. There are doctors in town that warn patients about the high sodium content in our water. It's awful. I did extensive research into gravity fed water systems and landed on the Waterdrop King Tank. We were impressed with the third party testing and certifications that Waterdrop has for their products (only found two that had this). This system was really easy to assemble. Really straight forward and everything felt like great quality! The spigot itself was so heavy you can tell its fully metal and well made. The filters were easy to soak. I will admit, priming them wasn't the funnest thing but honestly if that what someone would complain about, they are just lazy! Its really not that bad. You only have to prime it for 60 seconds. The water filters through very quickly. Which we hope is not a sign of poor filtration but according to their testing, it must work well. I had my first glass of water from it last night and it was incredible to have a glass of water that did NOT taste like a salty swimming pool. And no chlorine aftertaste. I'll be making our own stand to save money but even without it looks really nice on our counters. The 2.25 gallons will work well for my family of four in hot Texas. Especially since it filters so quickly. Can't be done until I mention price. We happened to catch it on sale which is what made our final decision. You just can't beat getting a third party tested system that OUT PERFORMS Berkey and is a fourth of the cost. Plus the filter replacement price is unbeatable when comparing literally all of the other brands we looked at and those (all but one) were not even third party tested and certified. All to say, very satisfied and would probably recommend this to a lot of people.

Noticeable Taste Improvement FOR REAL!!
I could actually tell a difference in the taste of the water, which was a nice surprise. Itโs still pretty early to fully judge long-term performance(bought it recently), but so far it seems to be working just fine. Setup was straightforward, and it does what itโs supposed to do without any issues. (Iโve used a Waterdrop sink filter in the past, so I already had some trust in the brand, so far so good) No leakage at all, and it filters water in a pretty decent amount of time. It looks good too(Had to say it)

Good for the price and easy to refill
I've been using this for about 9 months now and I can say it was definitely a good purchase. It is very easy to fill up and lasts about a day each refill for how much water I drink and the water just feels better to drink. The area I live in has a lot of chemicals and metals in the water and I fully believe this has improved the water quality of our drinking water.

Great water filtration system!
Iโve been eyeing a Berkey for a few years, but they donโt ship to California, so I was excited when I stumbled across the WaterDrop gravity flow system thatโs basically the same thing. Itโs a major bonus that itโs a few hundred dollars cheaper. There isnโt a sewer system where I live, and the ground water is terrible. I got a humidifier a few years ago, but have been unable to use it because after filling it with tap water, the mist coming out of it would smell like urine. Iโve been happily using my humidifier for the past few days and it smells like nothing. I also did the red dye test after it was assembled, and the water came out crystal clear. Iโve had no issues with leakage after assembly either. The reason Iโm giving it 4/5 stars instead of 5/5 is for two reasons: 1) Before assembly and every month afterwards youโre suppose to prime/flush the filters. They supply you with a gasket that youโre supposed to attach to the filter and to a water faucet (Iโve included a picture of this next to my kitchen faucet). They state that the gasket will fit around most faucets, but unless your house was built in the 1990s or before, Iโd guess there is at least a 50% chance it wonโt fit due to the variety of sizes and shapes of modern faucets. I wish they had made one side of that gasket stretchier to fit over all fixtures. 2) While assembly wasnโt difficult, attaching the faucet wasnโt exactly easy either. They do provide you with a wrench, which is a bonus, but because the walls of the WaterDrop are rounded you can only tighten the bolt 1/8 of a turn at a time. It probably took me 15 minutes to attach it. If you donโt own a bendy ratchet it takes forever to attach the faucet and get it tight. They also recommend disassembling the whole unit every month to clean it. There is no way a normal person will want to remove that faucet every month and reattach it. Overall a great system, I would definitely recommend it.

Money saver and delicious!
I ADORE this filter setup!! Although I did buy a 20inch stool to keep it on because counter space and itโs wicked short to the ground and bending over is bad for my back(Iโm disabled) I had a rust blemish on the inside I noticed and I contacted the company and they sent me a new one to replace it!! The water tastes amazing and Iโm saving over $2,000 a year on my bottled water!

Great filter for two people
This got great reviews online and so far has been working fantastic. The size is perfect for me and my two dogs. Not looking forward to changing the filter because that was a little tricky to get started, but it's worth it!

Waterdrop gravity filter system does not produce safe drinking water
I never leave reviews but felt that this is important to let people know. I purchased this item for my family because I thought we would have healthy drinking water. The water tasted good so did not think anything of it. After having it for months, I tested the water with a TDS Meter - a water quality tester. The result was 282 which indicated poor drinking water, not recommended. I thought maybe it was because the filters needed to be changed. I changed the filters and tested the water again. The result was 254 with the brand new filters. This is still poor drinking water. The range for poor drinking water is 151-300 ppm. I contacted Waterdrop and was told that the Waterdrop gravity system is designed to reduce chlorine and improve taste but it is not designed to reduce TDS - totally dissolved solids. I told them that I'm disappointed because their product does not produce safe drinking water. Check your options before purchasing this water filter system.

10 out of 10 would recommend!
I received my waterdrop gravity -fed water filter system today. I am very impressed with it. We have well water and I did a taste test and the water was good. I feel it tasted just as good as bottled water. It was easy to assemble. It filters kind of slow but that's not a problem for me. I would recommend getting the stand with it. So far very happy with this product!

Decent
Love it although there were solder marks on the inside near the spout hole which could potentially rust
