Who operates this website?
The testing service behind this website is Air Sense Environmental, an Edwardsville, Illinois company serving Greater St. Louis. Contact details and request forms lead directly to that provider. This educational guide is part of its service presence, rather than a laboratory directory or a separate testing business.
What does this guide cover?
Here you can compare measurement options, review preparation questions and understand the units on a radon report. The guidance also explains why a single number should be read alongside the test duration and location. Property transactions may introduce report requirements that should be established before the device is placed.
- Choose a test for the decision you need to make.
- Read the preparation instructions before testing begins.
- Retain the report instead of only noting its result.
How do I contact the provider?
Call 314-664-9807 to ask Air Sense about a test for your property. Tell the team whether the purpose is a purchase, a first home check or verification after mitigation. If another party needs the report, explain who that is and when they need it; the testing arrangements should account for those requirements.
