What to Do When Your Home Smells Musty (Even After a Renovation)
Amazon List of Recommended Items Here
1. Monitor Indoor Humidity Levels
Buy a hygrometer (digital is best; ~$10–$25 on Amazon)
Check all main rooms, especially:
Closets
Under sinks
Near AC vents
📉 Ideal Humidity Level:
Set your goal for 45%–50% indoor humidity (Never above 55%).
2. Add a Portable Dehumidifier
- Choose the right size unit:
- Small rooms (up to 500 sq ft): 20–30 pint unit
- Large spaces/open floor plans: 50+ pint unit or whole-house system
- Place in central location, away from walls
- Set humidity level to 45%
- Use auto-drain function if possible (hose into sink/drain)
🧼 Tip: Clean the filter every 2–4 weeks to maintain efficiency.
3. Use an Air Purifier with Activated Carbon
- Select a unit with:
- HEPA + Activated Carbon filters
- Optional UV light or ionizer for extra air scrubbing
🌬️ Helps remove:
- Musty odors
- VOCs from paint or renovation
- Mold spores and allergens
- Run on low or auto mode 24/7 when home is unoccupied
4. Set Your AC to Maintain the Right Climate
When the unit is empty or unoccupied:
- AC Temperature Setting:
- 76–78°F (24–26°C)
- Keeps air moving and prevents condensation
- Fan Mode: Set to Auto or ON
- Auto saves energy
- ON circulates air consistently (better for humidity)
💡 NEVER turn the AC completely off — stagnant air = musty air.
5. Additional Must-Do’s
- Leave closet doors slightly open for airflow
- Use moisture absorbers (like DampRid) in tight spots
- Wash and dry any damp towels, rugs, or linens
- Have ducts professionally cleaned if odor persists
- Inspect for hidden leaks under sinks, appliances, or in attic
👃 If It Still Smells Musty…
It’s time to call in a professional to:
- Test for mold
- Inspect AC ductwork and wall cavities
- Recommend permanent solutions like a whole-home dehumidifier or UV air purifier.
