Check Humidity Levels
Why It Matters
High humidity promotes mold growth and dust mites. Low humidity cracks wood floors and trim, and irritates respiratory systems.

Community Tips
A digital hygrometer like the ThermoPro TH06 ($15-25) provides precise readings within ±2% accuracy, far surpassing analog models that drift significantly over time and create false confidence in humidity control decisions.
Humidity levels above 60% accelerate mold growth on drywall and wood framing within 24-48 hours, particularly in bathrooms and basements where condensation concentrates -- addressing spikes immediately prevents costly structural damage and health hazards.
Check humidity readings twice daily (morning and evening) to identify the actual peak rather than a single snapshot, since moisture typically peaks after showers or cooking and may normalize within hours, preventing unnecessary dehumidifier investment. ---
