Reverse osmosis is a filtration method that removes harmful compounds found in water to make it potable. It uses pressure and a semi permeable membrane to purify water of impurities and foreign contaminants.
The RO filter has become very popular since its introduction to the market because more and more people are becoming aware of its benefits. Thus, reverse osmosis water filter products have become quite popular!
Though R.O. shower filter systems may be unnecessary in most cases, having a good supply of reverse osmosis drinking water would be healthy for pretty much anyone.

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?
How does the reverse osmosis process happen?
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.
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.
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.
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.
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.
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.
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.
