The FILTERSCAN WiFi® Home affordable airflow sensor and differential pressure monitor sends you a text or email when it's time to change your home's air furnace filter.

     Installing the FILTERSCAN WiFi Air Filter Monitor is straightforward and the unit is easily recalibrated each time the air filter is serviced.

    Because of this, you can change your home heating and cooling system air filter models without undermining clog-detection performance. The FILTERSCAN WiFi connects to the wireless router in your home.

    When you install the air filter monitor downstream, you place it on the cold-air return duct after the filter, and before the blower. This is the ideal location for installing the FILTERSCAN.
