Ionizers are devices that help improve air quality by releasing charged particles, or ions, into the atmosphere. These ions attach to airborne pollutants like dust, smoke, and allergens, causing them to clump together and fall to the ground. This process can make the air feel fresher and cleaner, which is especially beneficial for people with allergies or respiratory issues. In addition to air purification, some ionizers can also help reduce static electricity in homes and workplaces. They are often used in conjunction with other air cleaning methods, such as HEPA filters, to create a healthier indoor environment.
