Get an alert on your phone or tablet when it’s time to change your air filter. No need to set a reminder or check the filter surface for dirt—a sensor on these filters tracks your HVAC system’s airflow and usage, so you don’t change the filter too early or too late. The sensor is Bluetooth-enabled, so it pushes tracking information to a downloadable app.

A pleated construction gives these filters a large surface area to trap contaminants. These high-efficiency filters balance good airflow with high filtering efficiency and capture common allergens such as dander, mold spores, and pollen.

These filters are disposable, but the sensor contains a lithium battery. Follow local regulations for battery disposal.
