The Battle of Reverse Osmosis vs. Deionized Water Filtration

Do you use a water filtration system in your home? If so, you are probably aware of the amazing benefits and advantages of these systems, but did you know that different types of systems purify the water differently and have other benefits that may make them better suited for other unique situations?

For example, some filtration systems are better suited for purifying drinking water while others are only suitable for water used for cleaning or irrigation.

Two popular filtration choices for homeowners are reverse osmosis filters (RO) and deionized water filtration systems (DI.) There are many pros and cons of each, so, which is better overall?

How do RO and DI filters work?

These systems each produce completely clean and pure water suitable for multiple uses around your home, but the process used to get it is different.

Here are the main differences in how each unit works:

  • Rreverse-osmosiseverse osmosis does the opposite of natural osmosis, which works to move a solution from a low ion concentration to a high concentration.
  • Uses a specialized membrane to trap impurities, leaving your water pure and clean.

Deionized Water Filtration

Operates with a two-part process. The first step involves passing the water over positively charged ions to remove metals and minerals, then making the water neutral by exposing it to negatively charged hydroxyl ions.

DI water is used in many different industries such as the auto finishing industry, textiles, and pharmaceuticals.

What are the benefits of RO filters?

Reverse osmosis filters are great for homeowners looking to get peace of mind and make sure their water is safe to use and consume.

Some of the other benefits include:

  • deionized-waterHomeowners will save money by not purchasing bottled water. The filter will essentially pay for itself.
  • Up to 99% of dissolved solids are removed from the water with an RO filter.
  • One downside is that the porous membrane of an RO filter may let through larger debris. Homeowners often require two different filters for perfectly pure water.
  • RO filters are also known to waste water, which could result in a higher water bill.

What are the benefits of a DI filter?

DI filters are great in numerous situations.

Some of the most significant benefits include:

  • Your water will be perfectly clean and free of all bacteria and harmful minerals that may cause illness or make the water taste bad.
  • Homeowners will save money by not purchasing as much bottled water.
  • Some experts claim that DI filters remove trace elements from the water that are actually good for us and make the water taste better.
