Waterdrop NSF/ANSI 42&372 Certified Water Filter, Replacement for Berkey® BB9-2® Black Filters, ProOne® or Alexapure® Gravity Water Filter System and Waterdrop King Tank Series, (Pack of 2)

So far I am impressed! I wanted a Ber - key but wasn’t sold on the cost. When this came on sale for $170 including filters, I knew it was worth a try.First impressions:- It took me an hour to set up by myself. That included cleaning it meticulously and trying to get the filters installed correctly (that was confusing for me the first time but next time I’ll know).- I do recommend that you prime at least twice, as the instructions recommend. Like, fill it up all the way, let it filter through, drain it all, and repeat. I did it twice and I noticed that after two times it still had a lemon-y / metallic-y taste from the filters. By the third time that taste was totally gone.- So far I’m impressed with the water taste. I haven’t tested the water quality yet compared to my ZeroWater pitcher, but I will be. I’ll also update here once I know better of the longevity of the filters.But so far, I’m impressed and happy with my purchase. I have four people in my household who drink a lot of water and I’m happy to provide cleaner, healthier water for everyone.

Great off brand alternative filters I will continue to purchase as they are excellent quality and the price is right.

These filters do a super job. It is very easy to change the filters and prep for drinking. I find the WaterDrop system very convenient and simple to use.

We own a similar system of another brand so am familiar with how they work and how to maintain them so when I noticed the water tasting "off" I ran a red dye test to make certain the filters were seated properly. I reseated them three times and both filters allowed the dye to pass through - one worse than the other but both significantly pink. I've never seen anything like it in over 14 years experience. Absolutely worthless filters. Regarding the rest of it, the materials are very thin and low quality. If I'd seen it in person I would not have purchased it, it even looks cheap. As mentioned, I own a brand-name system which cost more $ but in this case, I got less than what I paid for :(UPDATE: After the Waterdrop company noticed my review they contacted me with an offer to assist. I chose replacements which they promptly sent. They worked! The photos show the red dye water before filtering and the clear water in the mason jars below. I also tried to show the red and clear water in one shot so you can see its from the same unit. In all fairness, the stainless steel container pictured is not the Waterdrop brand - that one is at our summer home & these are the more expensive tanks we bought first. As stated above, the quality of the unit is in keeping with the price paid. The Waterdrop was a lot thinner but also less $. Regarding the filters themselves, they are also a lot thinner than the other brand but also less $ so might need to be replaced more often - we'll see. I don't know how to test the fluoride filters so this update is a review for the charcoal filters only. Quite an improvement!

Love this water filter. Have had whole house and under-the-counter water filters before but this Waterdrop water filter system is better. The gravity component of filtering and the slowness works better. I have a daughter that is our cannery-in-the-mine. She has serious health problems and is very sensitive to the water. Consequently she can tell when the water filter is no longer doing an EXCELLENT job.This is a very good water filtration system BUT…the 6,000 gal filter number they give is probably based on pristine water. We can get about 700 gallons out of each filter before we have to change it. For normal people they may not need to change it that often AND we live where there is very hard water. I plan on staying with them and will just change the filter about every 5 months. (We have a family of 7 and drink about 4.5 gallons of water a day.)We did try to clean the filter but it didn’t work.

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.

Works great with our Berkey water filter! filter

Easy to set up. Filtration seems to work great and water has a good clean taste. We’ve had a couple minor product issues - like a screw breaking off between the white and black filter - and both times customer service has been immaculate and immediately sent us replacement parts for free. Super responsive and easy to do business with which is rare these days.
