Culligan FM-25R Faucet-Mount Replacement Water Filter Cartridge, 200 Gallon, Chrome

***Long short of this review, THIS IS AN AMAZING WATER FILTER!!! I HIGHLY RECOMMEND IT!!!***Here are the facts about this water filter:1) Consumer Reports highly rates this filter, “EXCELLENT (highest rating)” for LEAD REMOVAL, CHLOROFORM REMOVAL, & CLOGGING. Rated FAIR for FLOW RATE. The flow rate isn’t fast, but it is decent, and steady. I personally fill up several gallon jugs of filtered water & put them in a mini-frig for convenience.2) DO NOT RUN HOT WATER through the filter EVER, ONLY COLD WATER, or you will significantly reduce its life-cycle. I live in Pittsburgh where the water is over the federal lead limit & the water tastes bad unfiltered. This filter does an excellent job if you use the filter appropriately & the water tastes amazing. Some people say it doesn’t last more than a month. Filtering HOT WATER is possibly why so many people complain about it not lasting as long, or their water quality is so bad that the filter is working overtime.3) As previously stated, the FM-15A replacement filter is the SAME w/ a different color = BUY IT TO SAVE MONEY (b/c you can’t see it anyway unless you put your head under the faucet)4) Depending on whether your faucet has threads on the INSIDE or OUTSIDE of the nozzle, you MAY OR MAY NOT need to buy a cheap $3 METAL adapter at the hardware store. BUY THE METAL ADAPTER! DO NOT TRY TO MESS WITH THE INCLUDED PLASTIC ONE, the weak properties of plastic means it will fail either immediately from over-tightening or within the 1st month. TRUST ME, SAVE YOURSELF THE FRUSTRATION OF GETTING SPRAYED IN THE FACE OFTEN, & SAVE TIME. Note: Faucets use a STANDARD size, so just ask an employee about the correct & cheapest metal adapter that accommodates BOTH inner/outer threading. The only exception where this filter would NOT WORK is if you have a “DROP DOWN FAUCET” as noted in the description.5) The filter housing is PLASTIC, so when you screw the filter in to the housing, it should be tight, but there’s no need to try to torque it to make it super tight or anything, the filters deep threading seal it up very well.6) What to expect for the 1st use after installing the Culligan filter: 1) The water will spray WILD for a little while 2) You need to run COLD water through the filter for about 3 minutes to properly prime it & then it will normalize 3) If you followed the advice from all of the above, I believe that you are going to really love this water filter too! Enjoy!
