Review: 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.
Review: Great filter. Same as the expensive ones - I am thoroughly impressed with its performance. Installation was incredibly straightforward – it took me less than 10 minutes to set up, which is a testament to its user-friendly design. Maintenance is just as easy; changing the filter involves a simple twist and replace, with no tools required. The instructions are clear, making the process intuitive even for those not particularly tech-savvy. But where this filter really shines is in the taste of the water it produces. It transforms ordinary tap water into something refreshingly pure, stripping away any odd tastes or odors that were previously there. Each glass of water is now a delight to drink, encouraging me to stay hydrated throughout the day. Overall, this filter has exceeded my expectations in terms of ease of use, maintenance, and most importantly, the quality of water it provides. If you're looking for a hassle-free way to enjoy great-tasting water at home, this filter is definitely worth considering.

## Features

- Large capacity: The Waterdrop King Tank gravity-fed water filter system is a home water filtration system and comes with a 2.25-gallon large capacity, thereby meeting water demands of a family of 4 people for pure water indoors and outdoors.
- Outstanding filtration: The filter media adopted in the King Tank is natural coconut activated carbon, which effectively reduces chlorine and improves taste. You can get up to 99% of chlorine reduction (Tested by third party laboratory). The filter can effectively reduce impurities while improving the odor and taste.
- Longer filter lifespan: The two carbon filters (black) and two fluoride filters can effectively filter up to 6,000 and 1000 gallons of water. Go for the King Tank water filter if you expect an economical and sustainable solution to water filtration. Please note: Waterdrop is an independent brand.
- Ultimate convenience: King Tank water filter system can be easily set up and install all by yourself without prior plumbing experience. The water filter system requires no electricity to work.
- Please note: The system has only two installation holes for carbon filters, limit 2 carbon filters (or with 2 fluoride), which DOES NOT reduce TDS level. Reduce TDS cound check Waterdrop RO water purifiers. Note: This system is not sourced by Berkey.

## Questions & Answers

**Q: Where is the independent testing/third party on these filters? This company has a history of being deceptive about their filters.**
A: It’s March of 2022 I just spoke to “Mia” who is still fielding calls and then sending generic responses (it removes taste and odor!) via email with her name in them. 
Waterdrop filter reps have yet to substantively reply to my finite request for specifics of any/all products removed from water through (their carbon + flouride filters) and at what rate (%) of reduction. 
So too no responses were received asking for their NSF ANSI attainment levels. 
Based on a lack of any results in receiving their transparency thus far ...imho the lack of forthrightness negates my justifying a purchase of their gravity water system and/filters for purposes of water purification.

**Q: So where is the lab test rating?  Where can I find the lab test rating?**
A: I contacted the company to ask if they could send me a copy of the filtration quality metrics and third-party verification. This was their reply: 

“Dear [removed], 
Thanks for your reply. 
Sorry to tell you that we don't have the datasheet you need, please rest assured that our company offers quality products at a lower price without compromising quality. The filter materials in these are in good quality. 

Best Regards, 
Mia Lauren, 
Customer Service Rep”

**Q: I have a propur Big, it has 7" white ceramic filters.  How would I install the flouride filter that comes with these black filters?**
A: Install the black filter on the top of gravity water filter firstly, then install the flouride filter.

**Q: Would running one fluoride and one regular black charcoal filter be sufficient in my 2.25 Waterdrop System?**
A: Hi,
Thanks for your interest in our filter product.
Please note that we recommend using 2 fluoride filter and 2 black filter in the system to ensure performance, thank you.

### ⭐⭐⭐⭐⭐ 10 out of 10 would recommend!
*by S***5 on October 25, 2025*

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!
