The Airthings referral program makes it easy to share the gift of fresh air with the people you care about. Refer a friend and they get $70 (€70, £60, CA$90 or other currency equivalents) off when they purchase a View Plus monitor from airthings.com.

Read about:

You might see a message at the top of the Devices page in the app, or a gift icon in the upper-left corner.

But if you don’t you can always enter the Settings menu and you’ll find Refer a friend under the User settings.

As usual, there are a few things you’ll want to keep in mind.

Great! You can refer as many friends as you like. Each friend will be sent a promo code unique to you and which each friend can use only once. The code, however, can be redeemed by up to 5 different friends. Once it has been used 5 times, subsequent attempts to redeem it will be blocked. If this happens, please contact Airthings customer support and we’ll help you out.

Oh, and your friends should use their discount within 30 days of receiving it.

While our referral program is available to Airthings users in all of the countries we serve, unfortunately your promo code will only work on the store for your region. So if Bob in North Carolina shares a code with Tom in Canada, Tom won’t be able to redeem the code on the Airthings Canada online store.

We’re looking into how we can enable cross-border promo codes but for the time being the codes you send to your friends will only work in your country’s Airthings shop.

So do we. However, this particular promotion does not apply to everything on airthings.com. In fact, it is only valid for the purchase of one View Plus monitor and it can't be combined with any other discounts.

The good news is that View Plus is our best-seller and with sensors measuring 7 air quality factors including radon, PM, and CO₂, it's our most comprehensive monitor. There's no better way to start learning about and improving your home's air!

The message your referred friend gets will contain a link to a page explaining the value and giving them the promo code. It will look like this:

When they click Redeem my discount, they are taken to the View Plus page at airthings.com with the discount already applied. However, if they don't have the time to shop, there is also an option to copy the code to save it for use later.

Again, your friend may only use the code once and should redeem it within 30 days.

Yes, and you can read the terms of the referral program to get all the details.

But if you are concerned about your friends' privacy, we want to be clear. Airthings doesn’t save your friends' contact information and your friends will only receive the referral message that you choose to send them.

Airthings only maintains the relationship between you, as the Airthings account holder, and the promo code that was shared with your friends.
