Can Air Purifiers Prevent Colds?

People use air purifiers for many different reasons. Some users suffer from severe asthma or allergies, while others need them to protect themselves from cigarette smoke in their homes. For many users, though, air purifiers serve the more general purpose of keeping home air cleaner and healthier. These users often wonder whether or not their air purifiers can protect them from common illnesses, such as colds and the flu. That’s why we decided to answer one of the most common questions people have when they start looking at air cleaning systems: can air purifiers prevent colds?

Unlike many infectious diseases that are caused by bacteria, the common cold is caused by viruses. A virus differs from a bacteria in several ways, but the most important difference is size. The smallest viruses can be up to 20 times smaller than even the smallest bacteria, making them much more difficult to capture while airborne. For an air purifier to prevent colds, then, it needs more than just a regular filter.
