Describe your space and concerns. Get a prioritized action plan — source control first, then ventilation, moisture correction, and filtration — in the order that actually matters.
The most effective indoor air quality improvements follow a specific order: (1) identify and control the source of pollution, (2) improve ventilation, (3) correct moisture or humidity problems, (4) add or upgrade filtration, (5) verify with monitoring. Skipping straight to buying an air purifier often treats a symptom while leaving the actual cause unaddressed.
Important: This tool does not diagnose health conditions or measure air quality. It produces a general action plan based on the information you provide. For health concerns, consult your physician. For radon, CO, or significant mold, professional assessment is required.

This is not a health assessment or diagnosis. Selecting a sensitivity preference raises the recommended filtration target (e.g., a higher air-change rate) as a comfort and precaution preference — nothing more.
