Air Purifier vs. Dehumidifier: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 1, 2024
An air purifier cleanses the air of pollutants and allergens, while a dehumidifier reduces humidity levels, preventing mold and mildew growth.

Key Differences

An air purifier is designed to filter and cleanse the air of various pollutants, such as dust, smoke, and pollen. A dehumidifier, in contrast, primarily functions to reduce the humidity level in the air, making it less hospitable for mold, mildew, and dust mites.
