Recommend - I'm one year in on my first set of WaterDrop filters (chlorine + flouride), and I've loved them. Great taste, and what I like the most is that the carbon filters never clogged. I never needed to clean them. Just ordered another set. I recommend! Review: A great filter. Gravety feed so it's operable even without power. - High quality, efficient filters. Be sure to purchase the metals filters too. They're worth every penny filtering chlorine and fluoride. ## 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 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.

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.
