If you’re concerned about indoor air pollution and considering upgrading your home, you may be confused by the terminology such as air cleaner, air filter, and air purifier. This confusion exists largely because many companies that manufacture such equipment often use the terms interchangeably in their marketing. Is there a distinction? Yes, but it depends on who you ask, so with that in mind, let’s look at how the pertinent trade organizations define the terms air filter and air purifier.

Air Filter

Air filters trap particulates and other impurities contained in the air that passes through them. An air filter isn’t necessarily a mechanical device. The air filter for a central air system, for instance, is usually just mesh positioned at the mouth of the air return, which is responsible for extracting air from the residence. This protects the equipment and improves indoor air quality to a certain degree. The term air filter can also refer to a mechanical device — either whole-house or portable — that contains an air filter. These devices often have HEPA filters that can trap 99.95% or more of the particulates in the air.

Air Purifier

Whole-home systems are generally air purifiers, which clean the air beyond just extracting particulates, which is why they’re sometimes called air cleaners. The difference between an air purifier and an air filter is that the purifier employs a multi-pronged approach. Most include a HEPA filter, but not all do. As for the other functions, this varies between brands and models but can involve activated carbon, heat, ultraviolet radiation, negatively charged ions, ozone, sanitizers, absorption, and so forth.
