My Go-To Filter — Easy to Install and Works Well

Denisse VillarJuly 28, 2025✓ Verified purchase

I’ve been using this Waterdrop replacement filter for a while now and always keep it on repeat order. It fits perfectly in the Waterdrop pitcher, no wiggling, no leaks, and no need to force it in. Just a quick click and it’s good to go. The size is compact enough that it doesn’t take up too much space in the reservoir, so it doesn’t interfere with how much water the pitcher holds. And the capacity is great, one filter lasts me about two months with daily use, sometimes longer depending on how often we refill. What I love most is that the water always tastes super clean. It’s NSF certified and filters out PFAS and other contaminants, which gives me peace of mind. I can definitely tell the difference when it’s time to replace it, the taste starts to shift just slightly. Overall, this filter is super easy to use, reliable, and worth keeping stocked if you use the Waterdrop system regularly. Great performance without any hassle. Read more

Highly recommended water pitcher and filters combination!

NajahDecember 21, 2025✓ Verified purchase

This filter is a part of my all-time favorite water pitcher. I was elated to know that I could order replacement filters and not need to get rid of my pitcher. Since delivery, it feels like my life is complete once more. I can enjoy the clean taste of the filtered water at a great price. Some people may think they don’t make a difference in taste, but filters do change the taste. The fit is perfect, there are no smells, and a the water filters out pretty fast! I will be ordering again when my three filters are gone! Read more

Easy Replacement Filters That Keep Water Tasting Fresh

James SandovalDecember 23, 2025✓ Verified purchase

I picked up the Waterdrop WD-PF-01A Plus replacement filters for our pitcher, and they’ve been working great so far. Swapping out the old filter was quick and straightforward, with no leaks or weird fitting issues. The filter clicks right into place and feels secure. The biggest difference I noticed was the taste of the water. It’s noticeably cleaner and fresher, especially compared to when the old filter was overdue for a change. Knowing these are NSF certified gives extra peace of mind about what’s being filtered out. I also like that the filters last a reasonable amount of time, so I’m not constantly replacing them. They’re a solid, no-fuss option that does exactly what it’s supposed to do. Overall, these are reliable replacement filters that make everyday drinking water taste better without any hassle.

Excellent product. 100% satisfied!

WaterPeaMay 21, 2025✓ Verified purchase

Works great! Design is good - easy install. Good filtering speed. Water is significantly better in quality and taste. I especially appreciate how it filters out strong chlorine taste and smell. It says it's good for 200 gallons or 60 days. It is automatically programmed to go to "red light status" 60 days after you install it. But I live alone, and I know that I am not going through 200 gallons of drinking water in 60 days. So I calculate my own usage, and leave the filter in for longer - usually 90 days, and I am quite sure I could go even longer than that and still have it be adequately filtering. NOTE: if it ever starts running slowly, there are instructions for how to speed it back up. The easiest is just to pull the filter out, give it a really good shake, and put it back in. Works every time for me. It is probably a good idea to never let the filter completely dry out. But I refill my system at least once or twice a day, so that's not an issue for me. Excellent product. Highly recommend. Read more

Waterdrop, Great Tasting Water

Marilyn BraswellFebruary 5, 2026✓ Verified purchase

I love my Waterdrop refrigerator container. Most importantly, the water taste great, good sturdy quality, so easy to assemble, easy to refill and fits perfectly in my refrigerator. I have purchased 2 PUR refrigerator water containers, in the past and they seem to be, not built as sturdy as the Waterdrop. Read more
