The FILTERSCAN WiFi Air Filter Monitor and AirFilterSentry Notification and Reporting Service is the only device that can text you when it is time to replace your air filter. This is not based on time like other “air filter reminders.” It is based on the readings of a patented sensor. It is easy to install and will outlast your heating or cooling system.
Cleaning or replacing air filters at the right moment will keep your facilities’ HVAC equipment running at its peak efficiency while extending the life of your HVAC systems. Most filter changes are done on a fixed schedule, meaning that they are wrong almost all of the time. Waiting too long allows air filters to become clogged, potentially leading to more serious and costly problems, where service charges can exceed $2,000. Changing too soon means throwing away filters while they still have life left in them and is wasteful.
The FILTERSCAN® WiFi Air Filter Monitor utilizes patented differential pressure technology to monitor air filter clogging. In addition to providing local, text and e-mail alerts, it is compatible with single and multi-speed blower HVAC systems and most VAV (Variable Air Volume) systems, and is compatible with a wide variety of air filters. When servicing an air filter, you may follow the simple instructions on the front panel (see image below) or you may Reset the monitor to your new air filter via your AirFilterSentry account (see illustration below).

The FRADENPROBE®Air Velocity Transducer is an accurate, cost-effective sensor for nearly any market where air flow must be monitored accurately.
The FRADENPROBE uses patented, low power thermo-anemometry technology and produces a digital and analog linearized output. This makes it robust, easy to install, and usable in a wide variety of applications.
It is available with either a 1 meter cable or a 10 meter cable.
If you need to measure air flows through larger ducts, you can use an array of multiple units of the FRADENPROBE in conjunction with the SensorDock® Multi-Point Averaging Sensor and Power Supply.
