Warranty and Returns

airqio™ products are designed to provide reliable, practical indoor air quality monitoring. This policy explains the limited warranty and return conditions for the airqio™ AQ1 Indoor Air Quality Monitor, sold by BigWindow LLC.

1. One-Year Limited Warranty

The airqio™ AQ1 is covered by a one-year limited warranty beginning on the date of purchase.

This warranty covers defects in materials and workmanship arising under normal, intended use during the warranty period.

If your AQ1 is found to have a defect covered by this warranty, BigWindow LLC will, at its discretion, repair or replace the product. If repair or replacement is not reasonably available, an alternative remedy may be offered.

The warranty does not cover damage or problems resulting from:

  • Misuse, neglect, accidents, or improper handling.
  • Unauthorized modifications, repairs, or alterations.
  • Operation contrary to the product’s instructions.
  • Normal cosmetic wear or damage occurring after delivery.

To request warranty service, contact us with your proof of purchase, a description of the problem, and any relevant photographs or diagnostic information. We will provide instructions for the next steps, including return shipping if necessary.

Do not send a product back without first contacting us.

This limited warranty does not affect any rights you may have under applicable consumer protection laws.

2. Thirty-Day Return Policy

If you change your mind about your AQ1 purchase, you may request a return within 30 days of delivery, provided the following conditions are met:

  • The monitor is in new condition, with no signs of use or damage.
  • The monitor has not been provisioned or activated for use with an airqio account or monitoring service.
  • The product is returned with its original packaging and included accessories.
  • You provide proof of purchase.

A provisioned monitor is not eligible for a return under this change-of-mind policy. Defective products remain eligible for assessment under the limited warranty, regardless of provisioning status.

How to request a return

Contact us within 30 days of delivery to request return instructions. Please include your order number and the reason for the return.

Once your return is authorized, package the monitor securely and follow the instructions provided. Returned products will be inspected to confirm that the eligibility conditions have been met.

Approved refunds will be issued to the original payment method. Please allow additional time for your payment provider to process the refund.

Unless otherwise required by law, the customer is responsible for return shipping costs for change-of-mind returns. Original shipping charges are not refundable unless required by applicable law or the return results from our error.

3. Commercial Cloud Services

The AQ1’s Commercial operating mode requires a separate annual subscription for cloud data collection, historical monitoring, and dashboard access.

Returning a physical monitor does not automatically cancel a cloud-service subscription. Contact us separately if you need assistance with subscription cancellation. Any subscription refund will be handled in accordance with the applicable service terms and consumer protection laws.
