The global Deionization Water Filter Systems market size is predicted to grow from US$ 1707 million in 2025 to US$ 2670 million in 2031; it is expected to grow at a CAGR of 7.7% from 2025 to 2031.
A Deionization (DI) Water Filter System is a water purification system that uses ion-exchange resins to remove dissolved ions (charged particles) from water, including both cations (positively charged ions) and anions (negatively charged ions). This process replaces harmful ions, such as calcium, magnesium, sodium, chloride, and sulfate, with hydrogen (H+) and hydroxyl (OH-) ions, resulting in pure deionized water. DI systems are commonly used in laboratories, industries, and applications requiring ultra-pure water.
