Reverse Osmosis vs. Deionized Water Filtration

Reverse Osmosis vs. Deionized Water Filtration

Many homeowners rely on water filtration systems to purify their water and protect their family from illness and disease. Water filtration systems are a great way to save money on bottled water and ensure your drinking and washing water is clean and free of impurities. Several types of water filtration systems are popular with homeowners; sometimes it’s difficult to choose the filtration system that is right for you.

Two popular choices for water filtration systems include reverse osmosis filters and a deionized water filtration system. These two units are commonly confused with one another, and many people mistakenly think they do the same thing. Here are some of the most common differences:

How Does a Deionized Water Filter Work?

This process is commonly referred to as DI. It’s a two-step process that involves removing toxic ions from the water. To accomplish this, the water is passed over positive ions that remove any metallic ions from your water, including magnesium and calcium. Once the water is positively charged, it now has an excess of hydrogen ions that must be removed. The water is exposed to negatively charged hydroxyl ions, which cancel out the hydrogen ions and leave the water neutral.

Once the process is complete, the water is safe for drinking and washing. Deionized water is also commonly used in pharmaceutical production, auto finishing and the textile industry in other industries that require perfectly clean and neutral water.

What are the Pros and Cons of Deionized Water?

Different water filtration systems are best suited for different situations. While some filters may work for certain homeowners, it may not be right for others. Some of the pros and cons of using deionized water includes:

Taking into consideration the savings you will experience from not buying bottled water, the cost of a deionized filter is quite affordable.

DI filters make sure your water is free of ions and harmful minerals that may cause your water to taste or smell bad.

DI filters remove trace minerals from your water. Some experts believe that these minerals are good for you and make the water taste better.

How Does a Reverse Osmosis Filter Work?

Reverse osmosis filters (RO) force water through a semi-porous membrane in the opposite direction as natural osmosis. With natural osmosis, water is moved from a lower ion concentration to a higher ion concentration. RO moves water from a high ion concentration to a low concentration. The filter itself captures microscopic bacteria and other impurities that could impact the quality of your water.

What are the Pros and Cons of Using a Reverse Osmosis Filter?

Before installing one of these filters in your home, consider the positive and negative aspects:

  • RO filters remove 99% of dissolved solids in water including chlorine.
  • You will save money by not buying bottled water all the time, meaning the filter will eventually pay for itself.
  • One of the biggest cons is that the membrane of the RO filter can sometimes let through larger particles so you may want to have a supplementary filter to work alongside it.
  • RO filters are known to wastewater, which may result in a higher water bill.
  • Some experts believe that these filters remove trace amounts of some minerals that are beneficial and make the water taste better.
