Choosing Water Filters: Reverse Osmosis or Deionization?

Worried about impurities in your water? Are you constantly buying bottled water because you don’t trust the quality of water from your taps? A water filtration system is a great device to purify and clean your water. When it comes to filtration systems, there are many different types of units that work in many different types of situations.

For example, some filters are better for purifying drinking water, while others are better suited for irrigation systems.

Popular choices with many homeowners include reverse osmosis (RO) and deionized water filtration systems (DI.) These units have many unique benefits that make them the ideal choice for many homeowners.

Some of their differences include:

How RO Filters Work

water-filter-installationNatural osmosis occurs when a solution is moved from a low ion concentration to a higher ion concentration. Reverse osmosis does the exact opposite.

By forcing water through a specialized membrane, the water comes out pure and free of minerals and bacteria that could make it unhealthy to drink or use at home.

How DI Filters Work

Deionized water filtration is a system that is used in the auto finishing industry, textile industry and pharmaceutical development in addition to residential use. It produces clean and pure water ideal for washing and drinking.

DI filters start by passing the water over positively charged ions to remove metals and minerals. Then it is exposed to negatively charged hydroxyl ions to neutralize the water and make it safe to drink.

What are the pros and cons?

There are many benefits and advantages of these systems.

Here is a list of pros and cons for both systems:

Pros

  • deionized-waterHomeowners save money from not purchasing as much bottled water. This means the filters eventually pay for themselves.
  • Homeowners gain confidence knowing that their water is pure and clean.
  • RO filters remove up to 99% of dissolved solids in water.

Cons

  • RO filters tend to waste water, which could lead to higher water bills.
  • Some experts believe that DI filters remove trace elements that are healthy for us to drink and actually make the water taste better, overall.
  • RO filters are quite porous. At times, larger debris can get through the membrane. Many homeowners with RO filters use a secondary filter at the same time.
