Questions About This Site

Where should I start?

If you're actively dealing with a mold situation, start with the Mold Basics guide for immediate action steps. If you're researching health concerns, the Health Effects guide presents what major organizations actually say. For general learning, the Mold Basics guide provides the foundation.

Is this site selling mold testing or remediation services?

No. Mold Compass is an educational resource. We sell digital toolkits with checklists and templates, but we don't perform testing or remediation services. This independence allows us to present unbiased information.

How is this different from other mold information online?

We cite our sources. Every major claim is grounded in published guidance from organizations like the EPA, CDC, WHO, or peer-reviewed research. We don't exaggerate health claims to scare you, and we don't minimize real risks. We present what the science actually says, including the uncertainties.
