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 - Compatible with: Replacement for Berkey BB9-2 black Filters & PF-2 Fluoride Filters Combo Pack, Travel, Big, Royal, Imperial and Crown Berkey Gravity filter system. And it is compatible with Waterdrop Gravity-fed Water Filter System. The water filter is not sourced by or sponsored by Berkey. Waterdrop is an independent brand. - This filter set combines black carbon filters and fluoride filters to absolutely reduce harmful substances from the outdoor water source. With this product, you can breathe the fresh air and immerse yourself with fresh water. Please note that TDS level does not fully indicate the quality of the water and our filters DOES NOT lower TDS value. - The premium carbon block can absorb many impurities like sands, rust, sediment, bad taste, and odor. This product is characterized by uniform particles and a smooth surface to properly reduce chlorine, which is the primary cause of bad taste. Afterward, much cleaner water passes through the granular activated carbon to achieve superior performance on taste improvement. - Durable life span without compromising performance. To attain the best product performance, we recommend you replace the black carbon filter every 6,000 gallons per pair and replace the fluoride filter every 1,000 gallons per pair, which will be different based on water conditions. Please flush black carbon filter for 1 minute and fluoride filter for 20 seconds before use by connecting to faucet. Note: if faucet not fully compatible, splashing may occur but won't affect product. - Food-grade materials. Not only do we firmly control the filter material but also adopt lead-free materials to produce the filter housing. Waterdrop aims to provide you with a broad protection service. We have outstanding customer support service to enhance the use of our products. Our agents are available at all times to expertly attend to your questions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YV1GXSH | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #7,124 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #186 in Replacement Under-Sink Water Filters | | Brand | Waterdrop | | Color | Black | | Customer Reviews | 4.3 4.3 out of 5 stars (2,007) | | Date First Available | January 8, 2020 | | External Testing Certification | NSF/ANSI 42&372 Standard | | Included Components | Black Replacement Filters *2 Fluoride Replacement Filters *2 User's Manual *1 | | Item Weight | 3.14 pounds | | Item model number | WD-W7990 | | Manufacturer | Waterdrop | | Material | Carbon,Activated Carbon | | Number of Items | 2 | | Part Number | WD-W7990 | | Product Benefits | Removes impurities and improves water taste | | Product Dimensions | 7.48"D x 3.43"W x 12.59"H | | Set Name | Black Carbon Filters & Fluoride Filters Set | | Size | 2 Count (Pack of 1) | | Style | Black Carbon Filters & Fluoride Filters | | UPC | 840814168714 840814170878 840814194096 | | Unit Count | 2.0 Count | ## Product Details - **External Testing Certification:** NSF/ANSI 42&372 Standard - **Item Weight:** 3.1 Pounds - **Material:** Carbon,Activated Carbon - **Product Benefits:** Removes impurities and improves water taste - **Product Dimensions:** 7.48"D x 3.43"W x 12.59"H ## Images ![Waterdrop Gravity Water Filter, Replacement for Berkey®, Purewell®, ProOne®, BB9-2® Black Filters & PF-2® Fluoride Filters, Waterdrop Gravity Water Filter System, NSF/ANSI 372 Standard, Combo Pack - Image 1](https://m.media-amazon.com/images/I/513moEhfyTL.jpg) ## 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.
