Yes. It is possible to have an air purifier and a dehumidifier in one unit to achieve improved indoor air quality and increased humidity. Some air purifiers are integrated with built-in humidifiers, offering the convenience of both functionalities. However, if you want to have both devices separately in the same room, remember that each device should be positioned apart, ideally at the opposing ends. If not, the humidifier's moisture can cause the air purifier's filter to become clogged, which might encourage mold and bacteria growth.
