Waterdrop NSF ANSI 42 372 Certified Water Filter Replacement for Berkey BB9-2 Black Filters ProOne or Alexapure Gravity

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. Read more

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. Read more

These are good Filters! I like them On a side note, Amazon...Where's my Joke? It said if I review 7 items you'd tell me a joke. I've been ripped off on my Joke that they owe me. Boo. Read more

I purchased this in March of 2024. It’s been great, I have never done any kind of testing but the water tastes great… the only thing I knocked off one star for is the spigot gets very loose after about 8-9 months and there is a black water mark where it leaks (it’s not a steady leak) I have tried tightening it but it keeps loosening up. I’m debating on trying another brand…this one has been good so I hate to switch up. I would recommend this one but I would suggest buying an extra spigot. Read more

Great filters. No complaints. Tested first several gallons via food coloring test. Passed with no issues. Water tastes great. Highly recommended. Read more

The media could not be loaded. Even though the TDS barely budged and it basically runs right through the filter /: we do think the water tastes soo much more clean, crisp, less drying in our mouth, and much more refreshing. However, lol… I’ve read “TDS readings won’t change after carbon filtration because a TDS reading includes the beneficial minerals a carbon filter like this is letting pass through, but doesn’t include the harmful toxins that a carbon filter is filtering…” but many toxins that these filters claim to filter ARE soluble (fluoride, nickel, aluminum, lead, tin, mercury, etc) and if they’re being filtered, it should reflect a lower TDS reading. I definitely don’t think “0” TDS is the goal and using distilled/evaporated water would be another step to leaving more solids behind… but you spend good money on a carbon filter that’s supposed to work via adsorption: it needs contact time to efficiently filter toxins and the more contact time, the more efficient filtration. So this flow rate is questionable too because it’s so fast the toxins aren’t getting the contact time needed to be trapped and adhere to the carbon. Ideally, who wouldn’t want to send a sample to a lab to know exactly what’s in it! We just cant swing that and the reviews online made us skeptical of the home kits too. Maybe it’s removing the chlorine since it smells and tastes great, but the flow rate and TDS reading are definitely worth knowing about. Read more

I ADORE this filter setup!! Although I did buy a 20inch stool to keep it on because counter space and it’s wicked short to the ground and bending over is bad for my back(I’m 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 I’m saving over $2,000 a year on my bottled water! Read more
