If you've just purchased the FILTERSCAN or FILTERSCAN WiFi air filter monitor, you'll be interested in this three part series about how to install the FILTERSCAN, how to calibrate it and how to operate the air filter monitor.
Part 1: How to Install the FILTERSCAN
Installing the FILTERSCAN®Air Filter Monitor is simple and straighforward. Just follow these step-by-step instructions, also detailed in this 5:18 min installation video (which you'll find embedded at the end of this article):
1. Turn OFF your HVAC system until instructed below: Typically, this is accomplished by setting your thermostat to the “off” postion and/or turning power off to your central air/furnace.
2. Choose a place to install the FILTERSCAN: You will need to choose a location on the cold-air return side of the duct (where the air enters the system) at least 6 inches to either side of the air filter that is free of any impediments—either inside or outside the duct. Ideally, this location will be downstream from the air filter (that is, between the air filter and the system blower); however, you can also install it upstream and differentially. More on that in step 6..
3. Tape your FILTERSCAN monitor template to your chosen location: The template included with your air filter monitor tells you exactly where to drill, so you won’t have to make any complicated measurements.
4. Drill holes: Using a 7/64” metal drill bit, drill four mounting holes indicated on the template. Then, using a 3/8” drill bit, drill one hole for the monitor’s sensor.
5. Attach the Air Filter Monitor: Align the FILTERSCAN’s sensor tube with the larger hole (3/8”) that you drilled. Then, attach the monitor unit using the supplied mounting screws. Ensure that nothing is inserted into the Sensor Tube, as it could damage the sensor and interrupt proper functioning.
6. Set the Upstream/Downstream Switch: Flip the upstream/downstream slide switch (refer to the product image in the FILTERSCAN Quick Start Guide) on the monitor’s circuit board to indicate the chosen location of the monitor, relative to the HVAC filter’s position.
You have three options for locating the monitor: upstream, downstream and differentially across the filter. We'll go through each one.
a. Upstream: This refers to installing the air filter monitor on the cold-air return duct before the filter and blower (See Figure A below).
Figure A: Upstream Installation
b. Downstream: When you install the air filter monitor downstream, you place it on the cold-air return duct after the filter, and before the blower (See Figure B below). This is the ideal location for installing the FILTERSCAN.
Figure B: Downstream Installation
c. Differentially across the filter: In this case, the air filter monitor is installed either before or after the filter and using the optional Tubing Kit. Set the slide switch to the Downstream position for differential mounting. (See Figure C below).

7. Install Batteries: Insert four AA batteries (included), or install the wall-mount power adaptor (included). Once power is applied to the monitor, the status LED should momentarily turn green and then turn and remain red. This indicates that the unit has not yet been calibrated.
8. Replace the Cover. You're set! You've successfully installed the FILTERSCAN air filter monitor. You're ready to learn how to calibrate it.
