Monitor” button on the Home page and provide the information for the additional monitor(s). You are

For more detailed instructions on how to sign up and configure your monitor on the AirFilterSentry
website, consult the FILTERSCAN WiFi Installation and Reference Manual.
STEP 2: CONNECT TO THE AirFilterSentry™ CLOUD SERVER
Remove the front cover of the monitor by pressing on the sides of the housing. The inside of the
monitor is shown below.
Install the 4 included AA lithium batteries in the battery holder, making sure you put them in facing
exactly as shown in the figure above. When you do, a number of LED’s on the monitor’s printed circuit
board will start to blink. Wait about one minute until the blinking has stopped. There will be a red LED
on at the upper right in the figure above, and a green LED on at the lower right in the figure above.
Determine whether your router has a WPS button and where it is located on your router. If your router
does not have a WPS button, you will need to connect the monitor to the AirFilterSentry server using
the procedure found in the section “Connecting Your FILTERSCAN WiFi Air Filter Monitor with your
Wireless Router without a WPS Button” in the Installation and Reference Guide. Once you complete
that procedure, skip to Step 3 below.
Depress the WPS button on your wireless router and hold it for two to ten seconds, until its LED
begins to blink.
Using a pencil, toothpick, or other non-metallic object, depress the monitor WPS button (see the figure
above) just once until you feel it “click” and immediately release it. The WiFi Status Indicator will start
blinking green, then amber, and then green again. If the WiFi Status Indicator only blinks green or
amber before it goes off, and never blinks red, it has successfully paired with your router. You can now
go to Step 3.
