Review: ' - Product works just as expected. Flow rate is good. Installation was fairly simple other than reaching behind the sink to install the filter faucet. I experienced no leaks but I did use plumbers tape on all the connections. HIGHLY RECOMMEND! Makes my water taste so much better but I have to say its not Poland Spring.
Review: Great for water system - I need these 2-step filters for the drinking fountain attached to my kitchen sink. These for my system perfectly as expected and are easy enough to install (the hardest part is that the area under my sink is hard to reach). They seem to last a long time (4-6 months), just as long as my refrigerator water filter. They seem to do the job well and the water tastes good, after the initial rinse through. This 2 pack is the best value I've been able to find.

### ⭐⭐⭐⭐⭐ Clean, refreshing water
*by R***P on October 30, 2025*

We love our filtered water! We quit buying bottled water when we installed the water spicket that these filters go with. We change them out about every 6 months. They are worth the money to always have filtered water without needing to go to the store. Helpful tip- fill mason jars with the filtered water to always have refreshing, cold water on hand. I don't notice any taste or smell to our filtered water, which is really good because our city regularly has issues with tap water being smelly and discolored when the lake turns. They are easy to install- just take out the old ones, replace the battery- yes, it comes with the replacement battery- and then place the new ones in and you are ready to go. You should run the water for a few minutes before drinking the water to make sure any carbon dust is gone- that does give it a weird taste in the beginning. If you notice the water starts tasting like the lake or whatever your source of water is, then it's time to change them again, although the beep from the device should alert you first to change them out.
