How Does Reverse Osmosis Water Filtration Work?

Reverse Osmosis Water Filtration

Chances are you’re familiar with the concept of water filtration. You may have a Brita pitcher in your refrigerator or a filter on your kitchen faucet. But what is a reverse osmosis water filtration system and why might you want one?

Essentially, a reverse osmosis water filter system works by breaking down water molecules and rebuilding them without all the additives that are in the city water, such as chlorine or chloramine. Chloramine is a combination of ammonia and chlorine—and we’re fairly sure you wouldn’t like to consume those chemicals or apply them to your skin on a regular basis. A reverse osmosis system works to eliminate those contaminants through a 4-step process.


3 Benefits of the Reverse Osmosis Water Filter

Here are the top 3 benefits you can expect from getting a reverse osmosis system installed in your home.

  1. Removal of harmful bacteria, viruses, pesticides, chlorine, asbestos, sodium, and more.
  2. Improved taste, appearance, and odor of drinking water.
  3. Eco friendly, efficient solution to filtered water.

Reverse Osmosis Water System Maintenance

Water filter lifespan will vary by system, but typically they last between 12 and 18 months without being changed. Membranes can last between 3-5 years. However, since membranes are fragile, they can be more susceptible to tears, which are often invisible to the naked eye. To ensure that your reverse osmosis system is working correctly, it’s a good idea to get periodic water quality tests.

Health Considerations of Reverse Osmosis Systems

If you’re concerned about specific contaminants, you’ll want to look for a system that’s NSF-approved. This certification guarantees that the system has passed certain criteria for eliminating specific contaminants. While consuming large amounts of chemicals is not healthy, our bodies do need some minerals, such as calcium and magnesium, for optimal health. Tap water is a large source of these minerals. When you filter water to a higher degree, you also lose beneficial electrolytes. Some people with reverse osmosis systems choose to take mineral supplements to replace what they aren’t getting from tap water.

Is Water Filtration Right for you?

So water filtration really necessary? Of course, it’s a personal choice, when we asked our master plumber Joe if he would ever drink unfiltered water from a tap; his answer was a resolute “No”. “The water in my home comes from a reverse osmosis system,” he said. “This is the cleanest water you can drink outside of a laboratory setting.” To find out what type of water you’re dealing with, contact your local municipal water utility company. They will provide a water analysis free of charge upon request. Once you receive the report, you can identify potentially harmful contaminants in your water and decide for yourself if a reverse osmosis water filtration system is right for you.
