Legal

Limitation of liability

Select your region for the terms that apply to your purchase.

There are no warranties beyond those stated in this policy. Any implied warranties, including implied warranties of merchantability or fitness for a particular purpose, are limited in duration to this warranty period. Some states or provinces do not allow limitations on implied warranty duration, so this may not apply to you.

Under no circumstances shall Airthings be liable for special, incidental, or consequential damages arising from breach of warranty, breach of contract, or strict liability. Some states or provinces do not allow the exclusion of incidental or consequential damages, so this may not apply to you. This warranty gives you specific legal rights, and you may have other rights that vary by state or province.
