Indoor air quality has a big impact on how your home feels day to day, especially if you deal with allergies, dust, pet dander, or lingering odors. At the same time, dry indoor air during winter or in low-humidity climates can lead to irritated sinuses, dry skin, and uncomfortable breathing. That is why air purifier and humidifier combo units have become such a practical upgrade.

A strong combo unit does two jobs at once: it filters airborne pollutants while helping maintain a comfortable humidity range. For this 2026 roundup, we tested dozens of popular models and compared them for filtration effectiveness, humidification performance, ease of use, and overall value. Below are our top lab-tested air purifier and humidifier combo picks.
