[Original] Waterdrop WD-PF-01A Plus NSF Certified Replacement Filters for All Waterdrop Pitcher and Dispenser Filtration System, Reduces PFAS, PFOA/PFOS, Last Up to 2 Months or 200 Gallons (2 Packs)

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.

They are great filters. Buy them all the time

This is the best pitcher I purchased and these filters work so quickly and the water tastes much better after being filtered. Highly recommended.

It's pretty easy to replace the filter for this specific water jug - the one it's designed for - and the taste and clarity of the water is much better coming out than going in. So I'd say it's worth it to use this brand.

Easy installation into tank. Great sub for name brand.

Tap water taste great using these filters, they filter a lot of water and they are cheap. Trifecta of goodness.

The most perfect water filters for our DripDrop water filter. I love that I can buy a 3 pack that can last us without having to turn around and buy a new filter each month. Super easy to use and to “activate”. The size is perfect and the longevity of the filters seems to last even past the 30 days when we need it to… if you know, you know!

Water filters work amazing for a the first few fills and then they basically stop working, water will remain in the top and not drip into the tank. Thought it was a faulty filter so I used one of the replacement ones I got but it is acting exactly the same.Update: The filters themselves are not the issue. The problem appears to be with the design of the water filter dispenser itself in conjunction with the amount of air/water ratio that is possibly coming from our tap. If the water is poured on the filter it appears to stop working. The design flaw is that the opening on the lid exposes the filter so I have to angle the water flow away from the filters while filling the tank.
