Pros and Cons of Reverse Osmosis & Deionized Water Filtration

There are many different types of water filtration systems designed for different uses. For example, some systems are designed to purify drinking water, while other systems are better suited for irrigation or washing. Two of the most popular water filtration systems include reverse osmosis (RO) and deionized water filtration (DI.) These systems come with many pros and cons that may make you choose one over the other.

Let’s take a look at some of the biggest differences between the two:

Reverse Osmosis

RO filters do the opposite of natural osmosis. Natural osmosis is the process of moving a solution from a low ion concentration to a high ion concentration. RO filters use a specialized membrane to force water with a high ion concentration into a low concentration. The filter captures bacteria and other impurities that could make your water unsafe to use.

Deionized Water Filtration

reverse-osmosis

This filter uses a two-step process to remove minerals and impurities from the water that may make it unsafe or taste bad.

The first step passes the water over positively charged ions; this removes any metals or minerals in the water. The second step exposes the positively charged water to negatively charged hydroxyl ions that bring the water back to neutral. The result is perfectly pure and clean water.

Pros and Cons of These Systems

There are many pros and cons of RO and DI filters.

Here are some of the most significant differences:

Pros

RO filters remove up to 99% of dissolved solids in the water.
DI water is so pure it’s also used in industries such as auto finishing, textiles and pharmaceutical development.
Homeowners will get peace of mind knowing their water is safe to drink and use in their home.
The filters will pay for themselves with the savings from not purchasing bottled water.

Cons

RO filters are known to waste water and may result in a higher water bill.
RO filters are also quite porous and may let through large debris. Many homeowners use two filters for this reason.
Some experts assert that DI filters remove trace elements that make the water taste better and are actually healthy for us to consume.
