Understanding the Benefits and Risks of Using Deionized Water

Deionized water, or “DI water” is a mineral-free solution used in a number of industrial and medical applications. From pharmaceutical production and biotech, to industrial cleaning and manufacturing—this water absorbs ions upon contact, eliminating any calcified or corrosive build up on expensive equipment. Additionally, its neutral qualities make it a top-choice for water-based solvents that do not alter the composition of the solute. This makes it great for diluting medicines, foods, and chemicals used in biotech applications, along with being an effective ingredient for cleaning surfaces without harsh chemicals.


At iPolymer, we are international suppliers of engineer high purity fluid handling products, used in a number of important industries, such as semiconductor production, life sciences, gas analytics, and general chemical production. Our DI water spray guns and water systems utilize a combination class of high-purity polymer materials that do not contribute to the addition of ion particles in the water flow path. We select these specialized polymers to ensure a high-degree of chemical inertness, along with preventing any potential bacteria and viruses that could develop within the media. Before making any purchasing decision, it is important to understand how deionized water would work in your specific application. Here are some general pros and cons to help you decide.

Pro: Great for Cleaning and Lubricating Manufacturing Equipment

For high-purity applications, such as pharmaceutical production and food and beverage production, DI water is a great choice for cleaning or lubricating a manufacturing system. This helps prevent any calcified or corrosive build up that could harm your system, or negatively impact its efficiency.

Con: Does Not Remove Organic Material

As the name suggests, the process of deionizing water removes all ions – or charged non-organic particles – from the water. This process effectively purifies it for a number of uses, but is not able to filter out many of the organic materials and microscopic contaminants. Because of this, many high-purity applications using deionized water may also have to apply water filters and a reverse osmosis process to eliminate as many contaminants as possible. The distillation process, on the other hand, is able to remove a number of contaminants beyond just ions, and offers greater purity levels than deionization alone. Despite this, distillation takes a long time, has a hefty price tag, and still does not remove any organic contaminants.

Pro: Easier and Cheaper to Produce

Compared to distilled water, DI water can be produced quickly, at a significantly cheaper rate. Sine distilling the water requires boiling and cooling, this process can take a lot of time and energy costs that may not be necessary for your application needs.

iPolymer is happy to serve the needs of many industry partners looking for high-purity fluid handling products. Our DI water spray guns and water systems are built to last, in the most robust manufacturing and processing applications. If you are in the market for a DI water system or system accessories, iPolymer is the clear choice. Give us a call today at 949.458.3731 or request a free quote.
