I've ordered this for awhile and they are not only cost effective but great in my PUR. They don't last the full 3 months but the price makes it ok to buy more. Read more

Fresh Water is Essential
Cosmic Routes LLC—September 14, 2024✓ Verified purchase
I can’t say enough good things about Waterdrop! Not only do they offer high-quality water filters, but their customer service is truly top-notch. I left a positive review about my experience, and to my surprise, they generously sent me two additional filters as a gift and even refunded my original purchase. Their commitment to customer satisfaction is rare to find these days, and I feel so grateful to have chosen Waterdrop. Highly recommend their products and their amazing team! Read more

NOT AN EQUAL ALTERNATIVE
Jimmy—January 1, 2025✓ Verified purchase
This filter is NOT on par with an actual Pur filter. It only filters out taste… nothing else. If you want your water to have harmful things removed don’t get this filter. If you just want your water to taste better go for it. Read more

Works fine but came with low battery
vsamra—April 15, 2024✓ Verified purchase
What everyone else is saying is correct; the flow rate is great, the price is great, and it does the job. However, these filters come with an internal battery that activates the light on your sink attachment. When they are new, the light is green. When they hit the three month mark, they turn yellow, then eventually red. It’s to let you know it’s time to change the filter. I got the filter in a sealed bag, so I know it’s new. But the light is yellow. So I think the filter is just old, and the battery is low. Still filters water fine, but instead of relying on the light to tell me when to switch, I just have to mark my calendar. Read more
