Expect around 2 to 10 years.
However, if well maintained, Reverse Osmosis Water Filtration can last up to 15 years. So, the lifespan varies based on upkeep, water use frequency, filter quality, and the nature of the water.

Setting up water softener can help improve the traits of your water.
It also brings multiple benefits such as– lower utility and energy costs, softer skin and hair, shinier dishes and laundry, brighter clothing, less soap scum buildup, longer-lasting appliances, and better-tasting water.

You need water softener regardless of whether it’s well water or city water.
City water and well water sources— both have varying degrees of hardness. USGS Water Science School says— “well water might have higher mineral content than city supplies”.

Get rid of water contaminants with our Reverse Osmosis Filtration. Impurities affect your water’s taste, smell, and appearance. RO system helps trap and eliminate those contaminants and chemicals so you can enjoy “better-tasting, better-smelling” water. Moreover, the filter allows you to lower water bottle use and save money.

Some signs of hard water are— scale buildup on fixtures/appliances, soap scum in sinks and bathtubs, and poor lathering of soaps/shampoos.
Appliances like water heaters and dishwashers may also work less efficiently and wear out faster.
So, test water hardness to know if a water softener is needed.
