Kenmore 350 Whole House Water Softener System, 32,000 Grain, 1-4 People

Bought the Kenmore 350 to replace an Aquasure Harmony water softener which was annoyingly loud and did not perform as expected. I saw there have been some mixed reviews, but mostly because of shipping. Shipping: This came with Prime 2 day shipping and was delivered by two Amazon employees. They took good care handling the box to ensure the safety of the contents. Packaging: The water softener was packaged very well. The bottom was double protected with cardboard and foam. The top was covered in plastic bag, and foam packaged around the softener for stability during shipping. Installation: Installation was pretty straight forward. You do have to scan a QR code to get the manual, or you can go online and view the PDF. We will call it eco-friendly reading. The directions online in the PDF are easy to follow, and include diagrams. Design and Build Quality: The Kenmore 350 water softener is the same design as the newer Whirlpool water softeners. Whirlpool manufactures the Kenmore brand, so build quality is held at the top of Whirlpool standards we all have grown to love. The brine well and tank are an all-in-one design... space saving. I saw no signs of blemishes, cracks, or defects, and it includes a tank light for low lit areas. Water softness quality: After the installation and initial sanitizing regeneration, the water is very soft. I included a picture of the before and after test strips. It reads Zero gpg after installation which is perfect! Operating the softener: Press and hold the regeneration for approx 2 seconds to start an immediate regeneration. The regenerating process takes about 2 hours to complete and is near silent. When compared to the Aquasure Harmony, which uses between 60-80 gallons of water per regeneration, the Kenmore 350 uses about 30 gallons total. The default regeneration time is factory set to 2:00 AM, which I am sure most of us have not changed. Bottom line: You can't go wrong with the Kenmore 350 water softener. Kenmore's Trusted Performance is still top notch!

Easy to install; it's only been a short time but so far so good! Instructions were great

Excellent choice. Easy install. Works great

Very good features , my only complaint is there should be a manual with the machine,

We got the Kenmore 420 last time and it only lasted about a year and two months before the motherboard started acting up. I’m hoping this will last longer than a year, since this has cost quite a bit. Granted we do live in a desert, and the water softener is exposed to the outside all year long.

Do not buy this water softener, I purchased one in February on 2025 to replace my 25 year old Similar Kenmore. It stopped working in less ten 1 year, tried everything the owners manual recommended to no avail. Save your money and buy or rent something else. If I could I would give a zero star rating

We got this model as a direct fit plug and play unit to replace a nearly 20 year old similar model. This units plumbing fittings at the rear were about 3/16ths inch lower that the model we had installed. It was hard copper pipe and I did not want to redo the pipe. Luckily I had a spare piece of ceramic floor tile in the shop. I placed the tile on top the softeners previous platform and put the new softener in place. A perfect fit. The softener with its basic settings lowered our hard water from 125ppm to about 20ppm. Works and looks great

Easy to install, more energy efficient, less mineral build up on sinks,tubs,easy on clothes

Came with a damaged part
