    How to Connect the FilterScan WiFi to Your Home Wireless RouterReady to connect your FilterScan WiFi to your home router? 

    After purchasing the FilterScan WiFi air filter monitor, you may be wondering exactly how to take avantage of the best part of this wireless product. If that’s the case, we’re here to help! Just follow these easy steps.

    Even if you are familiar with linking devices to your wireless network, we recommend that you follow the steps outlined below.

    4 Steps for Connecting your Wireless Air Filter Monitor to your Router


    Locate the air filter monitor serial number and MAC address1. Locate the serial number and MAC address of your monitor, printed on the back of the monitor, as well as on the side of the shipping box.

    The serial number is 10 digits long. In the example pictured on the right, the serial number is 8138000040.

    The device-specific MAC address identifies the WiFi radio transmitter inside the monitor. It consists of 6 pairs of digits and letters, each separated by a colon. In the example pictured to the right, this MAC address is 00:06:66:69:8F:EC.

    2. Register the monitor on the AirFilterSentry website. Once you have written down the serial number and MAC address, open up a computer browser and go to www.cleanalertwifi.com. Then…

    a. Click on the “All Warranty Registration” button and enter the requested information.

    b. Click on the “Sign up for AirFIlterSentry (AFS) Home/Home+” button. Enter the requested information on each of the forms presented to you.

    C. Click on the “Submit” button after each form is completed. On the first form, "Create an Account," you must input a valid email address. It does NOT have to be the email account you want the air filter alerts sent to, but merely one that you use to validate the set up process . If you are signing up a single monitor, your plan type will be “Home.” To sign up more than one monitor (two or three), select the “Home+” plan type.

    d. When you click on “Submit,” an email will be sent to the email account you provided. Open the email and click on the link provided to verify your account on the AirFilterSentry website. You can now login to your account and finalize the Sign Up process.

    3. Remove the front cover of your monitor and insert the 4 included AA batteries (we recommend Energizer Ultimate Lithium batteries). A number of LEDs on the monitor’s printed circuit board will start to blink once the batteries are inserted. Wait about one minute until the blinking has stopped.

    Locate the air filter monitor WPS button4. Depress the WPS button on your wireless router and hold it for two to ten seconds, until its LED begins to blink. (If your wireless router does not have a WPS button, please click here for additional instructions).

    Using a pencil, toothpick or other non-metallic object, depress the monitor’s WPS button (see the example pictured to the right) 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.

    If the WiFi Status Indicator blinks red before it goes out, a problem has occurred in connecting your monitor to your wireless router. Go to the “WiFi Troubleshooting Guide” In the Installation and User Manual to find the source of the problem. Once you have corrected the problem, try to connect again.

    If you continue to have problems with any part of the wireless connection process, please email us at techsupport@cleanalert.com or call us at (888) 414-FLOW (3569).
