What should you know about RO water filters? Advantages and disadvantages
Drinking pure and clean water means taking care of your health. Tap water, bottled water, or water from other sources may not be 100% pure. So, installing a water filtration system is a good decision. Water filter manufacturers use different filtration technologies to ensure the best result. Reverse Osmosis is an effective way to filter water and make it free from contaminants. Let us learn more about RO water filters, including their pros and cons.

How do RO water filters work?
A Reverse Osmosis filter has a pre-filter for removing chlorine and sediment from water. Water comes out of the RO membrane and passes smoothly through the post-filter. That is why you get filtered water from your faucet. This type of filter involves different filtration levels. Every RO water system has a carbon filter and a sediment filter.
- A sediment filter helps in filtering out dust, rust, and dirt.
- A carbon filter is effective in filtering out chlorine, VOCs, and other pollutants that affect the taste of water.
- Another option is a semi-permeable membrane, which removes more than 98% of dissolved solids.
We have described the process of how RO filters work.
- Water enters the Reverse Osmosis.
- It undergoes pre-filtration (a sediment filter and carbon filter can remove chlorine and sediments that block the membrane).
- Water passes through the RO membrane (tiny dissolved particles not visible to the naked eye are removed).
- The water reaches the storage tank, and over time, when it is filled, it shuts off.
- After turning on the water faucet, you will get water from your storage tank. In this process, the post filter refines the water before it reaches the faucet.
Where should you install your RO filters?
Most commonly, RO filters are installed under your bathroom or kitchen sinks. You may also mount the filter in a cabinet.
Another option for you is to connect an under-sink RO filtration system to a refrigerator. It removes minerals so that you will get clear ice from your refrigerator.
Some consumers prefer a whole-house RO system to solve problems like high silica levels and saltwater intrusion.
Other applications of the RO systems are in pools, showers, agriculture, wells, and aquariums.
What are the pros of RO water filters?
There are several advantages to using these filters.
RO process removes most contaminants
Consumers always desire a filter that removes most microorganisms, dust, and contaminants. Your drinking water will be free from disease-causing microorganisms. RO systems filter mercury, chlorine, asbestos, lead, arsenic, and fluoride. However, make sure you have bought certified and tested filters. Low-quality RO systems may remove beneficial minerals like magnesium, calcium, and potassium.
RO is an eco-friendly filtration system
Plastic bottles and containers are harmful to the environment. However, very few consumers know that filtered water (treated with RO systems) is safer than disposable plastic bottles. Bottled water manufacturers are responsible for damaging the environment due to the lack of rules and regulations. The FDA has not made it mandated to disclose the source of bottled water or the contaminants it contains. So, it is safe to install a Reverse Osmosis water filter that provides you with great-tasting, healthy water.
Get better quality water for your everyday cooking purposes
Today, several restaurants have installed RO systems to wash raw ingredients with filtered water. They use this water for cooking food as well. That is why they provide you with tasty food. However, you can also choose this RO filter for your personal cooking needs at your home.
Cons of RO filters
Although RO filters are effective for water filtration, they have some cons-
Waste of water
RO systems use almost 3 times the amount of water they treat. You may find your water bills getting costlier. Some standard RO systems recover 5 to 15% of the water they have filtered.
Pressure drop
Some people have noticed a significant pressure drop in the water flow rate.
Need proper disposal of wastewater
You need to think of the right way to dispose of wastewater.
Conclusion
RO filters provide you with more than mere filtered water. The RO system retains the original taste of pure water by removing contaminants. You do not need to buy bottled water from the stores. As a result, you can save the environment from harmful plastics.
