Water Filtration: Reverse Osmosis vs. Deionization
In the quest for pure, clear, good-tasting water, you are probably aware that applying filtration to your tap water is the way to go. But what is the most efficient method to achieve your goal? While there are some ways to achieve pure water, there are pros and cons to consider with each one.
We’re going to take a look at two of the more standard home water purification solutions: reverse osmosis and deionization.

What Exactly is Deionization?
Water is deionized (i.e. the removal of minerals and impurities) by moving through a two-basin system. The basins use electricity to attract, isolate and remove ions (minerals) from the water, replacing them with hydrogen and hydroxide, which combine to form water, which is now free of minerals. This method is excellent at removing molecular impurities.
How about Reverse Osmosis?
Reverse osmosis (also known as RO) works by pushing water with pressure through a membrane. The membrane catches the impurities in the water (i.e. bacteria, minerals, etc.). It gathers these impurities and flushes them down the drain, meaning that the water that reaches your drinking glass is crystal clear.
Often, an RO system is used in conjunction with a carbon filter that acts as a back-up, removing residual impurities. This method effectively removes lead, chlorine, herbicides, arsenic, pesticides and fluoride.
Which One is Better?
As with many solutions, there are pros and cons to weigh out. The answer to which one is better has to do with what your specific needs are and what’s in your water.
The membrane used in reverse osmosis is extremely efficient at removing undesirables from the water, but its design doesn’t discriminate between “good” minerals and “bad” minerals. You may be removing some minerals that are to your benefit (i.e. calcium). You always have the option of using remineralization to put healthy minerals back in your water.
Deionization is believed to make water that has real health benefits and is more effective at hydrating. It removes toxins but leaves the “healthy” minerals behind. One drawback is that this system will require some maintenance over time to clean out the basins so that their electric charges remain potent.
