How to Unsubscribe from Spare the Air Alerts

There are several different types of Air District Spare the Air Alerts. You can follow the steps below for the alert type you wish to stop receiving.

Phone Alerts

These are recorded voice messages that provide an update when an alert has been called.

To unsubscribe:

  • Visit this web page.
  • Enter your phone number in the phone number field of the Unsubscribe box and click the “Unsubscribe” button.

Text Alerts (SMS)

These are text messages to mobile phones that provide an update for three different subscriptions lists: Summer, Winter, and Emergency.

To unsubscribe: If you are receiving messages from the official Spare the Air Alert SMS text service, you can unsubscribe by texting the word “STOP” in reply to your text alert message or to the number 817-57. For additional assistance, text the word “HELP” to the number 817-57.

If you want to unsubscribe from either the Winter or Summer Spare the Air Alerts only:

  • Text STOPW to 817-57 to unsubscribe from Winter STA Alerts
  • Text STOPS to 817-57 to unsubscribe from Summer STA Alerts

For more information on the Text Alert service, visit the Air District’s Spare the Air Text Alerts web page.

Note: There is an email-to-text service provided by EnviroFlash which is more complex to subscribe and unsubscribe from. If you are receiving text alerts that come from a number other than 817-57, you may be subscribed via the EnviroFlash service. If this appears to be the case, see the section below on Enviroflash Text Notifications.

Enviroflash AirAlert Email Notifications

These are email messages that provide an update when an alert has been called. Daily air quality forecasts are also available.

To unsubscribe:

  • Visit the Enviroflash AirAlert website
  • Click the “Manage Your Account” button
  • Enter the email address provided when subscribing to alerts (the email address at which you receive the Air Alert emails that you wish to unsubscribe from)
  • Click the red “Unsubscribe” button
  • Click “Yes” under the “Enviroflash Subscription Renewal” section

Enviroflash Text Notifications

If you signed up for text alerts on the Enviroflash website, you had to use your phone number as an email address in order to receive the emails as text messages. You will need that address to unsubscribe.

If you can’t remember your phone number email address, you will need to determine the text-to-email address for your phone number using these instructions on converting an phone number to an email address based on carrier. The format is dependent upon which carrier you have for your mobile phone.

To unsubscribe:

  • Visit the Enviroflash AirAlert website
  • Click the “Manage Your Account” button
  • Enter the phone number email address you used to subscribe (again, if you can’t remember it, you can convert based on your carrier and phone number via the instructions above)
  • Click the red “Unsubscribe” button
  • Click “Yes” under the “Enviroflash Subscription Renewal” section

Spare the Air App (iPhone and Android)

To stop receiving notifications via the Spare the Air smartphone app:

  • Go to your phone’s notification settings
  • Locate the Spare the Air app
  • Select the option to turn off notifications

You will still be able to see the current Spare the Air status by manually opening the app.

If you need additional assistance, you can call the Air District’s Communications number in the Contact box below.
