Specification

The FILTERSCAN WiFi Air Filter Monitor has the ability to allow the AirFilterSentry
Notification Service to update the Monitor software. During user configuration on the
AirFilterSentry Notification Service website, if you checked the “Allow Automatic Updates to your
FILTERSCAN Software?” box on the Edit Monitor screen and there is a later version of software
available on the server, your FILTERSCAN WiFi Air Filter Monitor will automatically download
the latest version of software and update itself without any action by you. The update will be
transparent and all operating parameters will be intact after the update.
1. Software updates will be made available by the AirFilterSentry Notification Service.
2. When an update is made available, the Notification Service will send an update command to
the FILTERSCAN WiFi Air Filter Monitor in response to the Monitor’s periodic status
message.
3. If you’ve elected to receive automatic updates, the Monitor then downloads and validates the
new software.
4. No further action is required on your part.

Appendix
Glossary
HVAC ………................ Heating, ventilating, and air conditioning
Dirty Air Filter ............... An air filter which has been in use and has collected some amount of dirt
or dust particles that discolor the filter fibers or element but do not
substantially affect the air flow through it.
Clogged Air Filter ......... An air filter which has collected a sufficient amount of dirt or dust particles
to not only discolor the filter fibers or element but decrease the air flow
through the filter as well. The FILTERSCAN WiFi Air Filter Monitor
typically identifies a filter as clogged when the differential pressure within
an HVAC system increases to 1.5 to 2 times the initial differential pressure
identified when the unit was calibrated with a clean filter.
Monitor ......................... The sensor voltage detection and signal processing portion of the system.
AirFilterSentry............... The application software and database residing on the Cloud Server that
provides all operational aspects of the AirFilterSentry Notification
Service.
