Clean Alert

The FILTERSCAN® WiFi Air Filter Monitor and Notification System from CleanAlert issues text/email alerts when an air filter needs servicing – ideal for operations or property managers responsible for servicing large or multiple facilities.

The patented and affordable monitor can communicate an air filter’s status to any smartphone (Android or iOS), or Internet-connected tablet or desktop computer (PC or Mac). An optional wired output can signal most remote building automation systems.

Using patented differential pressure methods to actively gauge a filter’s condition, the remote monitor is easy to install and operate, functions with a wide variety of filters, and is compatible with most commercial and industrial HVAC systems, including units with single- or multi-speed blowers.

By taking the guesswork out of servicing filters, the FILTERSCAN WiFi will optimize filter life while helping facility managers and building owners avoid higher energy bills, compromised air quality and costly repairs.

“We know that a clogged air filter is the primary cause of HVAC equipment failure and that eight of every 10 filters are not changed at the appropriate time,” says Terry L. Reavis, Vice President Sales & Marketing for CleanAlert, located in Oberlin, Ohio.

“The question of when to service an air filter has vexed building managers and HVAC contractors, for years and many users have resorted to servicing their filters according to a fixed schedule. Unfortunately this approach can lead to lost revenue and unnecessary material costs when filters are serviced too often.”

Ideal for both commercial and institutional applications, the FILTERSCAN:

automatically compensates for changes in system blower speed; can be installed upstream or downstream of a filter or differentially across a filter; and works with single-speed, multi-speed and most variable air volume (VAV) HVAC systems.

Measuring 6 inches x 4-5/8 inches x 1-1/2 inches, the FILTERSCAN unit incorporates an audible beeper and a green-yellow-red LED Status light to indicate various filter and system conditions.

When the pressure across a filter has changed by an industry-accepted amount due to the accumulation of dust and dirt, the FILTERSCAN indicates that the air filter should be serviced.

When connected to a remote device, such as a BAC or smart thermostat, the FILTERSCAN (model FS-245-C only) also provides a 5V DC output or an optional relay (dry contact) output to indicate that filter servicing is required.

The FILTERSCAN recalibrates each time a clogged air filter is serviced. As a result, end users can change filter models as they wish without undermining clog-detection performance.

“Users who wait too long to service a filter will allow pressure to build up in a system, thereby increasing energy costs and decreasing equipment life,” explains Reavis. “Installing the FILTERSCAN to monitor filters will eliminate this guesswork and ensure that the HVAC system is operating effectively, efficiently and safely.”

Text and email notifications require an Internet connection, wireless router, and subscription to the Notification Service (Basic service is free, reports included in Plus service with annual fee after the first year).
