Third-party (3P) sellers are independent businesses or individuals that sell new, used, or refurbished products directly on Amazon.com's or other online marketplaces.

While many third-party sellers operate legitimately, Airthings does not control their supply chain. This means we cannot guarantee:

• The product’s origin

• Whether the device is new or previously used

• Whether it has been returned, refurbished, or damaged

• Proper storage conditions (important for sensor accuracy)

• That the device includes all original components

When purchasing an Airthings device on Amazon (also valid for Target, Walmart, Best buy etc.) we strongly recommend buying directly from the reseller or from Airthings’ official store.

This ensures that you receive:

• Full manufacturer warranty coverage

• Access to customer support and technical assistance

• Eligibility for our extended 5-year warranty (where applicable)

On every Amazon product page, you can find the seller information under the “Sold by” and “Ships from” fields.

Look for:
