A reverse osmosis filter system is a big investment so it’s important that you take care of it. Maintaining your reverse osmosis system is important because it helps to maintain its effectiveness, saves you money, and prevents bacteria growth. One of the things you can do to maintain your system is to change your filters regularly. Over time filters get dirty and need to be replaced. They tend to need to be replaced every 6 months or so. Another thing is to drain the storage tank. Sometimes water stays in the storage tank for too long and it can become dirty. It is recommended you drain your storage tank every 2 weeks.
