Is It a Good Idea to Use Reverse Osmosis Water Filters?

We all want to protect our families and our health from contaminants present in the environment. This is one of the biggest reasons why we seek to filter tap water before drinking or using the water. The reverse osmosis filter is a popular water filter being used by many. However, understanding how it works and the benefits and drawbacks can be complicated. There are many advantages and disadvantages to look at.

Due to their ability to remove a large number of impurities from water, a bottle-less reverse osmosis water cooler is currently highly prevalent. However, there are numerous more components and aspects to be aware of while purchasing a RO filter.

This article will go over what this filter is, how it works, when it should be used, and the benefits and drawbacks of using it. By the end of this article, you should be able to decide whether or not to purchase a reverse osmosis filter for your home. There are many myths and misunderstandings about this filter which we will clarify.

What is Reverse Osmosis?

Osmosis is a natural process in which a liquid, such as water, travels through a membrane spontaneously. Some molecules, such as water, travel through the membrane or semipermeable barrier, but others, such as the bulk of salts, cannot do so.

Reverse osmosis occurs when the direction of the flow is reversed. Water molecules are pushed to flow through the membrane by simply pressurizing the concentrated solution, returning the proportion to the lower concentration. So, according to the example given above, this means that you would be pushing water from salty water back into freshwater.

How Do RO Water Filters Work?

A flat sheet membrane is used to make reverse osmosis membranes. It comprises three layers: a polyester base, a polysulfone layer, and a 0.2-micron thick polyamide layer, each serving a specific purpose. The polyimide barrier layer removes nutrients, chemicals, germs, and viruses from the water, while the polysulfone layer provides support and strength to the barrier layer.

The flat membrane sheet is paired with a feed channel spacer sheet, which causes turbulence and allows feed water to pass between the membrane sheets. These sheets are also given a permeate spacer sheet to let the final recycled water product flow uniformly throughout the entire membrane. The exposed sides of these membrane sheets are bonded together and rolled onto a core tube.

The feed channel sheet gets flooded with water. It begins to spiral from here, passing through the barrier layer and the permeate channel before entering the core tube. The final refined water is the end product.

Where Can This Filter Be Found?

Many companies manufacture reverse osmosis filters these days, but the key is to install high-quality ones. Wisewell offers a variety of RO filters that are both safe and reliable, using the most up-to-date technology. Their filters are easy to install and use. They have built apps that allow you to use smart devices and deliver sustainable quality tap water.

Is This Water Safe to Drink?

Because reverse osmosis removes a wide range of contaminants from the water, it feels like you’re drinking bottled water from your tap. Many people, however, are afraid that reverse osmosis will remove vital minerals. They frequently consider whether the dangers are worth the benefits. So let’s look at some of the benefits and problems.


  • As previously stated, RO systems remove more contaminants than any other type of water filter. Lead, chlorine, salt, fluoride, medicines, arsenic, and a variety of other contaminants are among them. If you have problems with any of these, a RO system is not only advised, but it could even save your life in some circumstances.
  • Although it eliminates a considerable number of minerals, water is not a significant source of your daily minerals. If you drink gallons of water, you may only obtain approximately 10% or less of the minerals your body requires.
  • By removing roughly 99 percent of total dissolved solids, reverse osmosis filters can help enhance the odor and flavor of your drinking water. This will also improve the flavor of your dish. The flavor of coffee, tea, soup, and most other foods created using water can be substantially improved by cooking with filtered, impurity-free water. This is why a lot of restaurants use RO filters.
  • Most filters should be replaced every six to twelve months, and the membrane every two years. The amount of time depends on the water quality in your location and how often you use your RO system. While some water filtration systems are difficult to operate and require a lot of time, a reverse osmosis filtration system is quite simple. Easily substitute the filters and membranes according to your system’s manual instructions.
  • There will be waste or “reject water” as a result of the level of filtration achieved by RO; however, this rejected water is insignificant in comparison to what we use for flushing and washing. As a result, having your water purifier does not result in you wasting any water in the process.
  • Reverse osmosis filters eliminate disease-causing microorganisms from water and provide a wide range of health advantages. It enhances digestive health, supports kidney function, hydrates and energizes our bodies, and improves the quality of our skin and hair, among other things.


  • Even though it uses identical technology, reverse osmosis systems might be costly in comparison to other water filters. The cost of RO filtered water is greater than any other refined form because the quality is superior. You should not choose lower-cost items at the expense of quality.
  • According to a report published by the World Health Organization, low mineral water is not recommended for drinking regularly since it can cause a mineral shortage. According to the study, consuming calcium or magnesium-deficient water might cause serious health problems such as heart disease.
  • Water filtration using a reverse osmosis system can take longer than expected. Filtering 3 gallons of water, for example, would take about 4 hours, implying that filtering enough water for everyone in the house would take at least a day. When compared to whole-house water filtration systems, this takes a long time.

RO Filtered Water VS Distilled Water and Other Filtration Systems

The most widespread forms of water filtration methods used in households are filters. It employs a barrier approach, which implies that some solid and other micropollutants are too large to flow through the filters and are therefore left behind. These can be produced from a variety of elements.

Activated carbon is the most commonly utilized. However, unlike RO filters, these filters are unlikely to remove a wide range of contaminants, even though they are inexpensive and can remove organic compounds and other specialized impurities to enhance smell and flavor.


Distillation is similar to the hydrologic cycle used by nature to purify water. It reaches a boiling point by heating tap water in a boiling chamber. Purified steam rises, leaving contaminants behind, and is moved into a cooling coil to be cooled back to a liquid. It is then stored in a glass or stainless steel holding jar/tank.

However, one main drawback of distillation is that it only removes pollutants with a higher boiling point than water. As a result, pollutants having a lower boiling point than water will still be present in purified water.

When compared, RO filter systems seem to be the better choice; however, it depends on your preference, your location of residence, and the quality of water in that area. If the water in your area is very highly contaminated, you should go for an RO filter system. You can find the level of contamination by doing various tests at home, or you can contact your municipality and ask them to come to your address and check the quality of water.

Should You Buy a Reverse Osmosis Filter?

With the information we have provided, answering this question should be a tad easier for you. However, we still believe that before opting for any water filter, you should do your research and weigh the pros and cons for yourself. Reverse Osmosis filters are indeed a great option for your home.

RO filters provide water that is beneficial to health, sweet-tasting, and makes everything you cook with it taste more delicious. They efficiently remove many contaminants and provide the best version of purified water.

If you are looking to buy an RO water filter system, you should book one as soon as possible because people purchase this fast. Purified water is very good for health, and there is no reason why you should not think of buying filters to enhance the quality of your home water and thus life.
