We have the replacement BestAIR Pro water pads you need for your humidifier. Also called evaporator pads, filters, or panels, water pads are the elements of your humidifier that increase the humidity of the surrounding air as they grow saturated with water. They are typically changed at least once a year. BestAIR Pro water pads are compatible with a number of humidifier models, including select models by Aprilaire, Lennox, Carrier, Bryant, Hamilton, Honeywell, Totaline, and Lasko. Be sure to check your unit’s model number to choose the correct water pad.
