Yes! Air purifiers and humidifiers can be used together. A humidifier and air purifiers serve different purposes. Humidifiers add moisture to the air, while air purifiers filter out pollutants from the air.
However, if using a humidifier and purifier together in the same room, it would make sense to put the humidifier either at the air ‘outlet’ side of the purifier, or a little distance away from the purifier. Putting a humidifier at an air purifier’s air inlet might mean the HEPA filter inside the purifier gets damp. Our data shows that washing HEPA filters with water significantly decreases performance.
