How Do RO Filters (Reverse Osmosis Water Filters) Work, Exactly?

In order to better appreciate your reverse osmosis water filtration system and to decide whether or not this type of filter is right for you, it’s a good idea to familiarize yourself with what you can expect from your filter. Below, we’ll give you a quick rundown of the types of contaminants RO filters can remove as well as the process by which this is done.

So... what can reverse osmosis remove, exactly?

  • Reverse osmosis filtration can remove many more contaminants than other types of filtration. If you know what types of contamination you’re looking to treat in your tap water, you may want to choose reverse osmosis to help you deal with the specific issues in your water supply.
  • Reverse osmosis can remove many different types of bacteria and viruses from the water. Although it may be able to remove up to 99% of viruses and bacteria, it should not be relied upon as the only solution for this type of filtration. You should always have a secondary filtration in place for viruses and bacteria.
  • You can use a reverse osmosis water filtration system to filter out physical particles such as dirt and sediment from your water supply. If you live in a place where you often have muddy or dirty water, then this may be a beneficial feature of an RO system for you.
  • Use reverse osmosis filters to remove dissolved salt in your water supply as well. This is a common problem in city tap water, and in some instances, the salt content in your water may be so high that it affects your health. If you’re concerned about this, then you may want to use an RO filter to get rid of up to 99% of the salt content in your tap water.
  • One of the most important elements of the filtration process of a reverse osmosis system is its ability to remove heavy metals and minerals from the water, too. You can use an RO filter to get rid of lead, to help improve hard water that has too much calcium or magnesium in it, and even to remove arsenic from your water supply, among many others.
  • Keep in mind, however, that RO filters are not as good at removing gases like CO2 from your water supply as they are with solid contaminants. This is not often a problem in tap water, but it may be an issue in some supplies as well as in well water. It’s a good idea to have your water tested for CO2 every so often to ensure you don’t need a secondary filter option in place to deal with it.

How does the reverse osmosis process happen?

  • 1
    Reverse osmosis filters begin with a filter that’s designed to trap physical, solid dirt and sediment. This step will catch calcium, rust, dirt, and any small pebbles or other similar solids that may be present in your water supply. 
  • 2
    From there, the water may go to a secondary, finer sediment step, although this is not true of every RO filter. Smaller and lower-cost filters probably will not include this stage.
  • 3
    Next is the carbon filter, which is the part of the process you’re probably the most familiar with. This filter is much like the type you might put in a filtration pitcher or in a fish tank. It contains activated carbon, which can filter out various types of chemicals including chlorine. This is important, because chlorine may wear down the membrane inside the RO filter if it comes into contact with it.
  • 4
    The next step is the RO filter itself. This is a membrane that is very thin and permeable. When the water moves through it, the membrane catches salt, heavy metals, bacteria, viruses, and other contaminants that the other filtration stages have yet to remove. The dirty, contaminated water is washed down the drain, while the clean water continues along the filtration process.
  • In some RO filters, the dirty water may be recycled back into the system in order to save water overall. This is not very common in household RO filters, however, but may be present in commercial-grade ones.
  • 5
    When water gets through the membrane in an RO filter, it has usually had at least 95% of its salt content filtered out. In many RO filters, the process is complete at this time, and the water is stored in the tank until you access it using your faucet.
  • 6
    Some RO filters contain a secondary carbon filter stage that ensures the water will be even less likely to contain chemical contaminants before it reaches you. Again, this is not very common in household water filters, but it may be present in some of the models you’re considering. Be sure to read the product details to determine whether or not your water filter contains this step.
  • 7
    Finally, some RO filters also have an ultraviolet sterilization stage. This is a little more common in household filters than some of the other optional features listed here. This step is added to help remove any remaining contaminants that might have made it through the membrane stage.

The entire reverse osmosis filtration process is managed using a filter pump system. Feed water moves through the pump, which in turn operates the system and allows the water to flow through the various filtration types and chambers of the system. Most household under-sink filtration systems are designed to be attached to the faucet in your kitchen, but there are also whole-house filter systems on the market too. No matter which you choose, they all tend to work in more or less the same way.

Reverse Osmosis Water Filtration: 
5 Things You Should Know About RO Water Filters

Understanding your reverse osmosis water filter and choosing the right one for your home is all about knowing just what RO water is—and what it isn’t. In this section, we’ll walk you through a few of the most commonly observed differences between reverse osmosis water (and filtration) and some of the other common variations out there. Read through this information and you’ll be better prepared to decide whether or not RO water is the right pick for your home, or if you need to go with a different type instead.

1. Reverse Osmosis Water Filtration Filters More Than Other Treatments

Reverse osmosis water filtration can remove more contaminants than carbon filters or distilled water filters. In fact, RO filters can remove not only bacteria and viruses, but also dirt and other solid sediments, microbes, heavy metals, poisonous substances, chlorine, other chemicals, and salt. One of the only things it can’t remove well from water is VOCs. Carbon filters are better at removing VOCs, while distillation filters don’t affect VOCs whatsoever.

If you’re looking for something that’s effective at removing most types of contaminants from your water, then an RO filter is the way to go. However, remember that it isn’t going to get your water 100% clean, and that you may want to have a backup plan in place for the types of substances it isn’t as adept at working with. Keep in mind, too, that it may remove important minerals from the water, although not as severely as distillation does. Distillation is more likely to remove important minerals from your water supply than any other type of filtration.

For the most part, carbon filters are considered the most middle ground in terms of filtration, while distillation filters are the weakest and RO filters are the strongest. Keep in mind, too, that the prices of these types of filters go hand-in-hand with their effectiveness, and that you should budget appropriately if you’re looking to purchase an RO filter.

2. Reverse Osmosis Water Filtration is More Expensive... But Worth It!

Reverse osmosis may cost more to set up, but less to run over time. This type of water filter is pretty pricey to get started with, especially if you go with a whole-house water filter. While it might be a lot more expensive to start up an RO filter, however, it isn’t going to cost much at all to run it once you get it started, and you’ll only have to worry about changing the filters once or twice a year in most situations.

Other types of water filters may be cheaper initially, but will end up being more expensive in the long run. For example, using a carbon pitcher filter that you keep in your refrigerator may only cost a small amount to get started with, but you’ll need to replace those carbon filters every month or so to keep your water fresh. You also won’t be able to get nearly as much use out of this type of filter and can pretty much only use it for filtered water. For this reason, going with an under-sink or whole-house RO water filter may be much more cost-effective as well as efficient and is sure to pay for itself in no time.

3. Reverse Osmosis Water Filtration Makes Water... Taste Different?

Reverse osmosis water has a different taste than carbon or charcoal filtered water. Some people like the taste a lot better, while others prefer the taste of carbon filtered water. This is because carbon filtration only gets rid of chlorine and other chemicals in the water (as well as solid sediments) and doesn’t remove all the other contaminants that may be present, including salt and minerals. RO filtration, however, removes it all, and may create water that doesn’t taste very much like its original source.

In some instances, this is a good thing; however, some people dislike the taste of RO filtered water. If you are concerned about this, you can purchase an RO filter that adds calcium and magnesium back into the water to give it a better flavor and make it healthier for drinking, too.

4. Reverse Osmosis Water Filtration Has More Water Filter Wastage

Reverse osmosis may waste more water than other types of filtration. This is not true of every RO filter out there, but it’s a common issue that some people may have with using this type of filter in the home. An RO filter operates by flushing itself with water and keeping water running throughout the process of filling the tank. Also, contaminated water is usually washed away at the end of the filtration process, unless you have an RO filter that recycles it in some way.

For this reason, yes, RO filters may waste a little more water than others. This may be an issue for anyone who is very environmentally-minded, but if you’re concerned about the additional cost on your water bill, don’t worry. Most RO filters only add pennies a month to the water bill, and most households with an RO filter don’t even notice the difference at all.

5. Reverse Osmosis Water Filtration Doesn't Need Electricity Like Other Water Filters Do

Reverse osmosis filter systems do not require electricity, unlike some variations of water filters. Yes, there are some types of water filters out there on the market that have to be run on electricity. These water purifiers are usually designed with a pressure boosting function built into the system, and they are meant for use with drinking water only. While they can be more efficient than a filter that doesn’t require electricity, there are many issues with this type of water—namely, if the power goes out, you won’t have fresh, clean, purified drinking water available until it comes back.

With most reverse osmosis water filters, you don’t have to worry about this. RO filters use a water pressure pump and don’t require electricity. However, if you choose to go with the type of RO filter that has an ultraviolet light stage at the end for sterilization, then you will need to use electricity for this purpose.

As you can see, reverse osmosis water isn’t totally different from the other types of household water filtration out there, but it’s not exactly the same either. This type of water filtration may be right for your home, but there’s always a chance it isn’t what you’re looking for. Consider all the pros and cons of RO filtration before deciding whether or not to install one of these systems in your home. Remember, however, that this is one of the most powerful types of household water filtration available, and that it can go a long way toward improving the quality of the tap water in your home.
