Good choice

Dr. Karen FrankeFebruary 19, 2023✓ Verified purchase

I gave my Birkey to my son and decided to buy this knock off as a replacement for it. The filters that came with it are not water purifers, birkey filters are. It was less money and came standard with features I would pay extra for if I purchased another birkey. I love the stainless steel spout with the see through water level. It is wonderful. I did purchase the stand as I had not with the original birkey and realized it is an asset. I love this unit and highly recommend. Its the same quality as a birkey at quite a bit less cost. If you buy and want your water purified, I suggest you use Birkey filters in it. It works well. Its worth the room it takes on the counter to have purified water and it works without electricty. Its gravity fed. Read more

Super product: Waterdrop 2.25G Gravity-fed Water Filter System, with Sight Glass Spigot

RickOctober 12, 2024✓ Verified purchase

I recently purchased the Waterdrop 2.25G Gravity-fed Water Filter System, and I am very happy with it. I was pleasantly surprised that it was easy to assemble, even for my 80-year-old mother. The 2.25-gallon container is just the right size for an average two-person household. The filter system removes all weird tastes and odors, and it filters water very quickly. The spigot on the tank is well-designed and helps you determine the water level, which reduces water spillage from overfilling the tank. This system works as described and arrived on time. I would say that it is a good investment that is well worth the money. In addition to providing clean, great-tasting water, it also helps reduce landfill waste and global warming. Read more

Good basic filter

Archana RanaAugust 10, 2025✓ Verified purchase

A good gravity filter, basic model doea not have the fluoride filter. The water takes okay not super great. I think using waterdrop pitcher after this filter would improve the taste of the water to perfection, haven’t tried that yet but this is a good basic filter Read more

Better than the competition!

Lexi’s FavoritesJune 28, 2025✓ Verified purchase

I’ve been a PUR and Brita buyer up until this point. I decided I wanted something a little better and bigger for my big family. The flavor of the water in this filter is way better. It was easy to set up. I’m happy with the size. I love that it has a water level indicator so I don’t have to open it up to see how much is left. Read more

Higher quality stainless steel container than my Berkey

Madison GraceNovember 28, 2024✓ Verified purchase

We bought our 2.25 gallon (Big Berkey) system 10 years ago and we have loved it. However, I always knew that, should we be in an emergency situation, I would need more water filter capacity than what we have. This year, I decided it was time to increase that capacity. Yet, the cost of the Berkeys has more than doubled since our initial purchase. I took a look at Waterdrop, read their reviews and decided to go forward. I do wish that I could have purchased the 3. 25 gallon size, but they don't offer that. To my surprise, the stainless steel container is nicer quality and it is even prettier! The sight view water spigot is also better because of the little red dot that helps you see the water line with more ease We did not order the one with 4 holes (for the flouride filters) because there has been a pledge that flouride will be removed from our drinking water in the new year. After the 2nd flush of water running through the system, the filters worked great although I have not done the red dye test on them yet. I can always revert back to using the VERY overpriced Berkey filters if I am not pleased with the Waterdrop ones. I am just grateful that I have an alternative that isn't so pricey. I am VERY PLEASED with this product. Read more

Doulton filters made the water taste metallic, total waste of money, undrinkable water. Scary!

‘LivNovember 18, 2020✓ Verified purchase

I bought these filters based on all of the 4/5 star reviews which I find stunning. I can only surmise that people are checking the “5-star” for ease of installing” because they ARE easy to install. You just place it in hole and screw it on just like the Berkey’s.. It’s not rocket science. Maybe that’s bringing the overall rating up? BUT These filters don’t even come close to the Berkey filters. After priming them (just like Berkeys) and filling my Berkey with hose water 5- TIMES through the system the water had a pure sickening metallic taste that took all night to go away. The scariest part is the water from the hose tasted perfectly fine with no after taste of any kind which means these filters are created the disgusting metal taste. All 6- people on our trip said the same thing! Like everyone else (guessing here) I bought these filters because the Berkey replacements are stupid expensive. I cannot express how bad the Doulton water tastes, the time it takes for the metallic to leave your mouth and in our group 3- upset stomachs through the night. We use this on our boat and did not bring bottled water with us. We actually had to pull anchor and go into a marina to buy water. Extremely upsetting and scary putting “God knows what” into our bodies. Who really knows what’s inside of them since they don’t go into detail. Since I’m past the 30-day return time I’m stuck with them. I’ll start saving up for the Berkey filters and use bottled water until I can buy the real ones again. In 15- years this is the worst “knockoff” product I’ve ever bought. Lesson learned. We have the Berkey King and use 4- of the black filters.. with no fluoride filters. With the Berkey King and 4- Berkey filters the water tastes delicious, which is an odd thing to say as it has no taste at all. Those who use Berkey will understand... Save up for the Berkey!
