BestAir A35PR

Keep your cool mist humidifier operating effectively with the Aprilaire 35 Replacement For Lennox X2661 replacement water panel humidifier filter pad. The water panel slides into the scale control insert and water distribution tray, where it begins to absorb water. Once saturated, the humidifier moves air through the filter which adds humidity to the room. Humidifiers are great for alleviating cold weather symptoms such as cracked lips, bloody noses, sinus irritation, coughing and more. Keep cold weather symptoms at bay and replace your filter today!
