7-Year Customer!
Great product for the price. I purchased my water filter almost 7 years ago because we live on the 4th floor of an apartment, drudging cases of water was exhausting, costly and not envorinmentally-friendly; so we have been buying these 6-packs ever since. It’s easy installation, the quality reader is still functional and has a long-time wear on it, but we are water drinkers in my house, including the dog using filtered water, so we go through these filter replacements pretty quickly between 3 people and one dog – I want to say a 6-pack will last us over 6 months (not sure if that’s standard or not). I have never had a faulty or leaky filter before either and the water quality tastes great. As long as my unit is still working, I will forever be purchasing these!

Quality taste for a like new product
I can’t talk about the quality of the water or anything about percentages in comparison to the PUR filters as I don’t have the “quality tastebuds” or the equipments to tests these things; they taste fine in my opinion and filtered the water to where I can notice the difference from tap, and they install the exact same way as the PUR filters: simple and with ease.What I do want to talk about is the “used” purchases for those worried about them. I bought one like new for the steep discount, and when it arrived, it came in with just one opened. I was worried that it might have actually been used, but after speaking to an Amazon representative about it and testing it for myself, it’s totally new, good quality, but just opened! The opened filter is clean with no signs of previous usage, no leaks formed with the filter, and is fine! The rest of the 5 filters were unopened, so I would say that this is a good deal! In a way, even if the one opened was not new, you’re getting 5 brand new ones for a steep discount (I paid around $25 for it, so that’s $5 per filter). If you’re worried about getting the used ones, I would say that you’re good to go!

Good water flow.
Easy to use and install. Works just like normal ones. Water tast just the same and appears clean (no lab testing done). The pressure/ water flow though, twice as fast! I will probably buy them again.

No difference in Waterdrop than more expensive filters.
This is a great replacement for PUR faucet. I have never seen any difference in either water filters and the price is lower for the Waterdrop.

Shop with confidence (updated review)Not a good product
Updating my original review to a 5 stars after speaking with the customer service for this particular item, I felt more comfortable with my purchase and will buy again because of the confidence the seller provided to me and the clarification. Don’t hesitate to reach out to the seller if you have any questions, they will respond.———-The product does not match the description. In fact, using the filter results in dirtier water. The taste of the water remains unchanged.
