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

Edited by Sumera Saeed || By Sawaira Riaz || Updated on November 18, 2023
An air purifier removes contaminants from the air, while a humidifier adds moisture to the air to maintain humidity.

Key Differences

An air purifier is a device designed to cleanse the air, removing particles like dust, pollen, and bacteria. On the other hand, a humidifier is specifically meant to increase the moisture content in the air, ensuring the environment doesn't become too dry.

The primary function of an air purifier is to improve air quality by filtering out pollutants and allergens. This can be beneficial for those with allergies or respiratory issues. Conversely, a humidifier combats dryness in the air, which can be helpful in preventing dry skin, throat irritation, and other related issues.

Air purifiers often use filters, such as HEPA filters, to trap unwanted particles. Some even have UV lights or ionizers to kill microorganisms or make particles easier to filter. In contrast, humidifiers release water vapor or steam into the air, using methods like ultrasonic vibration or evaporation.
