Though reverse osmosis is a different water purification system than traditional filtering, it still employs filters as part of the complex process. Just like any other filter, reverse osmosis water filters will need to be replaced from time to time. It is important to consider this fact in advance, so you can make a realistic water treatment budget that factors in future costs.
Reverse osmosis uses a traditional filter at the beginning of the process, in order to screen out dirt and sediment and other particulate pollutants. The heart and soul of a reverse osmosis system, however, is to drastically reduce the amount of dissolved solids that are in your water. These require a special filter known as a semi-permeable membrane.
Filtering Out the Bad
By forcing water through this membrane, your reverse osmosis drinking water system separates the untreated hard water from your purified soft water. This removes minerals like lead, calcium and magnesium, as well as various pollutants. The result is fresh clean water that you and your family will be delighted to drink.
The key to always having the finest water is to monitor the TDS levels of your water after it has gone through the reverse osmosis process. TDS stands for total dissolved solids, and your system should be removing at least 80 percent of these solids for the water to be good enough for you to drink. Take TDS readings frequently, so you’ll know when it is time to replace your reverse osmosis water filter.
