Review: Second purchase, zero regrets - Let me preface this by saying this is my second time buying this exact filter from this company. I bought one for my first apartment and it outlived my stay there. I moved into a new apartment and purchased it again without hesitation. Water taste? GONE. 100%. The strong chemical taste and smell are completely gone. I live in Fort Worth, Texas, where the municipal water is treated with chloramines and has a higher, alkaline pH (this is publicly reported in the city’s water quality data). If you’re sensitive to taste and smell like I am, you’ll immediately notice the difference. Design and installation: It’s long, slim, and takes up very little space, which is perfect for apartment living. I bought the quick-connect version and installation was quick and straightforward. It does require a few basic tools, but the process is simple and well explained. Important install tip: Keep filter replacement in mind when choosing the install location. You’ll need enough clearance underneath to remove it. Replacement is a twist-and-pull-down motion, so don’t install it too close to the cabinet floor. Planning ahead makes future filter changes easy. (Leave like 2-3 inches open) Practical and environmental bonus: I’ve stopped buying bottled water. A 40-pack at Walmart is around $6 and it goes fast. This filter cost me $129.99, and spread over about 5 years that’s roughly $26 per year, which is far cheaper than constantly buying bottled water. On top of the savings, it significantly reduces plastic waste, which matters to me. (Although I would never let it reach max capacity to be honest) Final thoughts: I genuinely love this filter. It’s effective, compact, easy to replace, and ideal if you live in an apartment and don’t have the option for a whole-house system. (Reverse osmosis still the best thing BUT I CANNOT AFFORD IT) Everyone should have one. My only wish is that I had the same filtration in my shower as well. Highly recommend.
Review: Great filter to easily improve your water quality. - This product comes with everything to install as a main filter or on a single line. IF you bought a water filter faucet to be installed in addition to the original OR you purchased a Kitchen Faucet WITH Water Filter Faucet, you will need to buy an additional splitter for the cold-water supply valve. Really good choice if you live in a apartment or rental property. Not a install and better than using a pitcher for drinking water. The price and ease of installation makes it easy to remove and take it with you for the next place. The filter is thin and a little tall but fits nicely under the sink. The part that you mount, where the filter installs to, has the ability to lift up and be removed as a complete unit before taking the filter off. That helps to have something under it to catch water when you remove the filter. I purchased a pressure gauge to see when the filter is getting to the end of its life. Ad says 2 years of use, MAX. That depends on many factors but the two easiest is water Use and Quality. Water quality can greatly reduce the life. If you have a well or if the municipality has sediments, mineral deposits, and "other", the life will be far less. If you have the filter in line with the main faucet and dishwasher, more water flow, the more water used, the more the filter is catching. The 10UA is good for 11000 Gallons. The 15UA is good for 19000 Gallons. You can look up water usage on USGS. Can you buy the 10UA and upgrade the filter to 15UA later, yes. The mounts are the same. Water quality is really good; Price point is great; Filter replacement cost is budget friendly.

- 𝐓𝐃𝐒 is not a professional way to measure the water quality. Essential minerals such as calcium, potassium, sodium, and magnesium are dissolved solids, so PPM may not drop if you test with a TDS meter.

- 𝐍𝐨𝐭𝐞: The activated carbon is made from natural coconut shells. Please confirm whether you are allergic to it. 𝐀𝐭𝐭𝐞𝐧𝐭𝐢𝐨𝐧: The extended filter life of this filter requires more filter materials, resulting in a larger product size. Please verify the dimensions of your undersink space before making a purchase.
