RO filters are easy to install and replace in many household systems. The actual price of an RO water filter system is around $200-300 to start out with and with some of the water costs and maintenance is factored in, the total cost is around $1000. The reverse osmosis filters last for around 3-5 years though and are relatively inexpensive to replace. The thin filter membrane should be replaced every 2-3 years to ensure that none of the smaller molecules, like chlorine, are getting through the larger RO filters.
The savings you recieve from having a RO water purifier over long term use is well worth the initial investment. Plus, the clean and pure taste of fresh water to your house is always worth it. Most homes can produce up to 50 gallons of RO filtered water a day, but some can go up to 100 gallons a day! If larger amount of water need to be filtered each day you may experience extra costs, such as a new water tank and upgraded reverse osmosis filters.
