Filters with an RO system are the most popular in the United States today for a reason. They can produce high-quality water that tastes good and is free of contaminants, so it’s safe to drink.
In the next section, we’ll discuss the primary types of RO systems on the market, and we will discuss the top qualities to look for during your purchase decision.
Types of RO Water Filters
All reverse osmosis filters work the same way by having water pass through a semipermeable membrane before the filtration stage. However, RO systems are available in a wide variety of different kinds of filtration designs. Each of these systems has its own pros and cons and fulfills various purposes and goals.
Some types of RO systems can filter water for an entire household, while others are intended for a smaller scale use. The primary types of RO filtration systems you can buy on the market today:
Countertop Water Reverse Osmosis Filters
Countertop reverse osmosis water filters (i.e the ZIP filter) are among the easiest to install.
- Basically, remove the faucet aerator from your sink and screw the filter into the faucet.
- You can then filter massive quantities of water without ever needing to modify your plumbing.
Moreover, countertop water filters are far less likely to have clogging issues than faucet filters or pitcher filters. The biggest negative is they take up countertop space.
Faucet Water Reverse Osmosis Filters
Also known as faucet-mounted RO water filters, these are another great choice when it comes to ease of installation. Simply unscrew the aerator from the tip of the faucet and proceed by screwing on your filter.
One of the best features of faucet filters is the ability to switch between unfiltered and filtered water. Yet, the most notable negatives are the fact they can’t fit every kind of faucet, and they also can slow down the flow of water.
Water Filter Reverse Osmosis Pitchers
A reverse osmosis water filter pitcher can be stored in your refrigerator or somewhere in your kitchen. It’s the right choice when you need to filter water for one or two people. Still, for larger families, it’s definitely going to be a little bit overwhelming filling it up all the time.
Water pitchers can also vary significantly in terms of their performance, as some are very slow and can clog easily. In contrast, others are very long-lasting and can filter through water easily.
If you’re going to buy a water filter, a reverse osmosis system could be your best bet. They are very effective at producing high-quality water free of contaminants and bacteria. So, water passes through membranes first and then through the filter to achieve this quality.
Why Do You Need to Invest in an RO Water Filter?
Before you begin researching the top qualities in a reverse osmosis system, you will first need to ask – do you even need water filtration in the first place?
The primary purpose of a water filter is to remove contaminants and pollutants from water. You may expect the tap water from your sink to be clean and drinkable, so you may still question whether a filter is necessary. The truth is lead, bacteria, and pesticides get into our water more than you may think, including metropolitan and dense urban areas.
Because Reverse osmosis systems use a semipermeable membrane to remove undesired molecules and particles from your drinking water before they pass through the actual filtration stage, so RO systems take a step further than other kinds of filters
Therefore, the number one reason to invest in a reverse osmosis system is to eliminate all possible contaminants that could be present in your tap water. Tap water can contain many impurities that can end up being very detrimental to your health, including cysts, parasites, bacteria, heavy metals, and other pollutants.
Consumer Confidence Report
All water suppliers are required to provide water quality reports to their customers each July called a Consumer Confidence Report (or CCR for short). Each CCR should include the level of contaminants detected in the waste. They also should show how those levels compare to the drinking water standards set by the EPA. If you have any concerns about the water quality in your home, the CCR will tell you the contaminants that are present.
If the CCR document from your water suppliers does indeed indicate a higher level of contamination than average, you would be wise to invest in an RO system. But even if the CCR indicates everything is within normal levels, you should still invest in a filter anyway to be on the safe side.
What Are the Top Water Filtration Methods Compared to RO?
All RO systems work to accomplish the same task – they use various filtering methods to eliminate sediment to create clean water. It includes particles, dirt, debris, sand, etc. Beyond that, modern-day filters also remove harmful substances in water that you can’t see, namely pesticides, chemicals, heavy metals, bacteria, and other microscopic particles that can harm your health.
There are many different kinds of water filtration methods besides reverse osmosis. However, reverse osmosis is arguably the most effective option because all water is forced through a semipermeable membrane before being run through the filtration stage.
The primary different water filtration methods are as follows:
Particulate filters remove visible offensive substances from water, such as dirt, particles, sand, and other debris. While particulate filtration on its own cannot remove bacteria or chemicals or other microscopic substances, they are often the first stage in water filters. Reverse osmosis is more effective because it can remove bacteria and chemicals that particulate filters cannot.
Activated Carbon Filtration
Activated carbon filters eliminate contaminants through the process of chemical bonding. This is an excellent filtration method to use for addressing odors or tastes that are caused by substances such as chlorine. However, it still lacks the semipermeable membranes of RO filters and therefore does not remove all molecules that RO filters can.
Reverse Osmosis Filtration
Just in case it’s not already clear, reverse osmosis systems work by forcing water through membranes to remove contaminants that are larger than water molecules. This process does not remove chlorine, but it does eliminate a lot of other contaminants that carbon filters don’t.
For each gallon that is filtered, RO systems will generate multiple gallons of wastewater. Reverse osmosis systems are also a highly effective filtration method for removing parasites, viruses, bacteria, and various heavy metals such as lead.
Ultraviolet, or UV, filtration utilizes UV light to remove harmful substances such as viruses, bacteria, and cysts. However, it cannot remove all undesirable chemicals, which reverse osmosis systems can do.
Ion exchange filtration works by replacing contaminant ions by using more acceptable additives. An example would be replacing magnesium with sodium. It is a conventional filtration method used in water softeners, but it doesn’t remove all other contaminant ions entirely as RO systems can.
A filter that uses any of the above filtration methods can be a good option. Still, reverse osmosis systems are by far the most effective because they simply remove more contaminants and molecules than the other systems. It is why filters that use reverse osmosis are the most common in American homes today. Reverse osmosis filters are very effective at removing contaminants from water at a constant filtration rate.
Water Filter Buyer’s Guide – The Top Qualities to Look For in Reverse Osmosis Systems
Regardless of the type of RO system or filtration method you choose, make sure your reverse osmosis system has each of the following qualities:
The filtration rate may not be something you care about if you’re just using it for personal drinking water. The filtration rate refers to the amount of water that RO systems can produce each day. If your overall consumption of water outweighs the amount of water that the RO system can provide, it’s not the best choice for you. It is why paying attention to the filtration rate is essential.
The maximum filtration rate varies significantly among different RO systems today. Filters designed to produce water for a more significant number of people (such as families) should have a higher maximum filtration rate than those designed for singles or couples.
The quality of water the RO system produces is more important than the maximum filtration rate. RO systems will remove harmful contaminants from the water. The second purpose is to improve the quality of the water, meaning getting rid of any foul odors or tastes, ensuring proper maintenance of pH balance, and the keeping of any healthy natural minerals in the water.
One reason why RO systems using the reverse osmosis filtration method is sometimes not the best choice; they can also remove natural minerals, such as calcium, sodium, or magnesium. You want to have these minerals in your everyday drinking water for health reasons – they promote bone density. Be sure to purchase a reverse osmosis water system that does not remove these kinds of minerals.
Ease of Installation and Maintenance
The filter you choose should also be easy to install and maintain. You don’t want a filter that isn’t user-friendly or requires professional installation.
Most RO systems use filter cartridges that need replacement depending on the level of use. For most, the cartridges will need replacement at least once every six months to one year. Be sure to get a filter that utilizes widely available cartridges. Make sure they are easy to install too.
RO systems will also have different maintenance requirements depending on the model. The more complicated RO systems will demand more of your time and your money. Be sure to research the maintenance requirements of the filter you are considering before you buy it.
The price of an RO system within your budget is essential. You can’t just take into account the upfront cost of the system itself. You need to consider the long term costs, such as extra filter replacement cost or how much electricity the filter requires (if any).The overall cost of a water filter is mainly determined by the number of stages needed to process the water. RO systems with more stages are going to be more expensive than RO systems with fewer stages.
In summary, you should choose to buy a water filter that is affordable, easy to install, and easy to maintain. Look for one that produces high-quality water at a suitable filtration rate. Reverse osmosis water systems are some of the most popular filter types on the market.
Water Filtration: FAQs
What’s the Process of Water Filtration?
Water filtration is when water passes through a water filtration system to remove contaminants and certain chemicals. Also, depending on the filter to improve the quality and taste of the water as well.
How Do You Know If Your Water Is Contaminated?
Get your local CRC, or Consumer Confidence Report, to learn what is in your water. If you are using a private well where the CRC does not apply, you can send your water for analysis to a certified laboratory.
Are There Any Water Filtration Systems That Are Maintenance-Free?
No, all filtration systems require some degree of maintenance. Still, the level of maintenance required for certain filters is higher than others. Filtration systems that utilize more stages to process water may do a more thorough job. They also are more complex and more maintenance-heavy as well. Virtually all systems will require you to replace the water filtration cartridges periodically. Always follow manufacturer instructions.
Can Filters Help Bad-Tasting Water Taste Good?
Depending on the filter, yes. One reason why reverse osmosis filters are so popular is the ability to remove specific contaminants such as fluoride, chlorine, or nitrates to improve the overall quality of taste. Be sure to have a water analysis done first. If you want to enhance the flavor of water throughout your whole house, make sure water entering your home is being processed by a filtering system.
What Should You Do If Bacteria Has Infected Your Water?
Any coliform bacteria present in your water is a firm indication that bacteria contamination has taken place. At this point, you will need to have your water disinfected and retested for coliform. If there are known bacteria present in your drinking water, use the best filtering method. It can be an Ultraviolet (UV) disinfection, which will make your water safe to drink.
Is Chlorine Bad for You?
Chlorine itself is not a severe risk to your health, other than the unpleasant smell and taste it has. The most significant health risk of chlorine is the fact that it can react with natural organic materials, and this creates a bad by-product in the form of carcinogens. Any point-of-use water filtration system in your house that utilizes carbon filtration will be advantageous in reducing the level of chlorine in your water.
What Is Ultraviolet UV Filtration?
The ultraviolet UV system utilizes UV to kill viruses, cysts, and bacteria that can be present in a source of water. How effective the UV system depends on the intensity of the UV, combined with the amount of contact time. You would be wise to pre-treat your water with another filtration system before you also run it through a UV filtration system as well.
What Is Reverse Osmosis Filtration?
The reverse osmosis system is one of the most popular filtration systems used today. This system contains both pre-filters and post-filters and works by passing untreated water through a semipermeable membrane, which will allow water molecules to pass through into a storage tank. The impurities will be separated from the water molecules and sent down a drain.
Is Distilled Water Purified?
Yes, if water has been distilled, then it has been purified by evaporation and condensation cycles that do not involve dissolved solids.
Do You Need a Reverse Osmosis Filtration System in Your Home?
One may wonder what the main difference is between whole house water filters and reverse osmosis filters. And, most importantly, when should we choose one or the other?
We will try to offer an answer here:
- You want a reverse osmosis water filter if your water performed poorly on water tests and has contaminants in it that whole house water filters cannot remove (some viruses, some chemicals, fluoride, etc);
- Some of the best reverse osmosis filters are the ones you install under your sink to get pure water that also comes enriched with minerals.
- Sometimes, an under-sink RO system is the best choice in case you do not have space or the plumbing infrastructure to install heavier, larger pieces of equipment.
Some say reverse osmosis systems are not the eco-friendliest option one can choose. However, modern technology and permeate pumps help you with your water conservation efforts while providing you with clear, healthy, and safe water.
Those interested in completely cleaning their household water can consider reverse osmosis water filtration systems. Even better are those filters that add in healthy minerals so that you receive quality water that also tastes good.
