A Brief Guide to Mold, Moisture, and Your Home

EPA (U.S. Environmental Protection Agency)

General homeowner guidance on moisture control, small-area cleanup considerations, water damage, and when professional help may be appropriate. It does not validate Mold Scanner AI or any individual screening result.

Mold: Basic Facts

CDC (Centers for Disease Control and Prevention)

General public-health information about damp and moldy environments. Individual responses vary, and building observations cannot determine the cause of symptoms. Consult a licensed physician for symptoms and assess the building separately.

WHO Guidelines for Indoor Air Quality: Dampness and Mold

World Health Organization (WHO) · 2009

A population-level review of dampness, mold, and respiratory health. Population associations do not diagnose an individual's condition, identify the cause of symptoms, or create a pass-or-fail score for a home.

Public and Private Burden of Illness from Dampness and Mold

Mudarri D, Fisk WJ · Lawrence Berkeley National Laboratory · Indoor Air, 2007

This study examines dampness and mold at a population and economic level. It cannot determine the condition of a particular home or whether an individual's symptoms came from a building.

BREESI (Brief Environmental Exposure and Sensitivity Inventory)

Palmer RF et al. · International Journal of Environmental Research and Public Health, 2021

This third-party study describes a health questionnaire. Mold Scanner AI does not administer BREESI or QEESI. Health-related onboarding answers remain on the user's device and do not change visual-screening results.

QEESI (Quick Environmental Exposure and Sensitivity Inventory)

Third-party research instrument

QEESI is not part of Mold Scanner AI and is not used to diagnose a user, modify a scan, or attribute symptoms to mold. Questions about symptoms belong with a licensed physician.

Air, Surface, and Settled-Dust Sampling

Different methods answer different building questions

Air, surface, and settled-dust samples are not interchangeable. No single method can inspect every concealed area, declare a home safe, diagnose illness, or determine whether symptoms were caused by mold.

ERMI and HERTSMI-2

Research indices, not medical or safety thresholds

ERMI and HERTSMI-2 scores do not establish universal health, safety, or re-entry thresholds. They should not be used to diagnose illness, confirm symptom causation, or replace a building assessment.

IICRC S520 Standard for Professional Mold Remediation

Institute of Inspection, Cleaning and Restoration Certification

This professional remediation standard discusses assessment, containment, air filtration, removal, cleaning, and post-remediation verification. It is cited for educational context only. Neither the separate free web checklist nor the mobile app is an IICRC inspection or remediation protocol.

Professional Scope and Interpretation

Building questions stay separate from medical questions

A qualified building professional should explain the scope, methods, access limits, findings, and uncertainty. A licensed physician should evaluate symptoms. Neither the app nor a building test connects those two questions.
