Response from AirBubbl by RensairSep 20, 2021
Hi David, Thank you for your feedback. As we mention on our website, the particulate matter and gases that the AirBubbl remove are not always visible to the human eye, so it is not always easy to clearly “see the difference” the AirBubbl is making. However, the AirBubbl is independently tested by third parties such as Enviro Technology Services who have confirmed the performance of the AirBubbl in independent expert testing against a range of products from this sector. We are more than happy to send you this paper on request. In the meantime, here is a certification from the Institute for Energy and Environmental Technology. V. (IUTA) from Germany, testifying the efficiency of the AirBubbl. https://www.airlabs.com/wp-content/uploads/2021/01/IUTA-Test-Certificate-July-2020.pdf I hope this clarifies your doubts. All the best, AirLabs Support Team
