How to Use This Page

STEP 1: Start with “Podcasts” and listen to one of the first three with Dr. Jill Carnahan, and then listen to all 3 with Dr. Neil Nathan.

STEP 2: Review the “Home Assessment Tips” to evaluate if you may have moisture problems in your home.

STEP 3: If you are concerned about mold in your home, discuss with your doctor and also review the “Mold Reduction Products to Consider” and “General Tips for Mold Prevention”

STEP 4: If you are considering moving, review the section under “Moving”. For information on what to take/not take from a previously contaminated home, review the podcasts as above under STEP 1.

For Clinicians:  I recommend reviewing this page, and then continuing to the Mold Information for Clinicians page.

Home Assessment Tips

  • Open windows/doors daily if possible to get cross-ventilation and outdoor air inside---do this for anywhere from 10-30+ minutes as able, the more the better

  • Use a dehumidifier as needed to keep humidity down

  • Get a humidity sensor (cheap on Amazon, etc) and confirm humidity in bathroom, etc. staying at least < 50%

  • Discusses air filtration: Camfil Mold and Air filtration for IAQ

General Tips for Mold Prevention

FOR MOVING (Rentals):

  • Any musty smells?

  • How is the ventilation (are there operable windows, does the air feel stale, etc)?

  • Is there good exhaust or window in bathroom?

  • Is there carpet (carpet can hold onto mold spores)?

  • Is there an energy recovery ventilator? (this brings outdoor air into living space)

FOR BUYING (consider the above tips and also):

  • Do full inspection of attic, basement, crawl space (any signs of water damage?)

  • Is there any water intrusion in basement? Try to visit during rainy season/day

  • How is the ventilation (are there operable windows, does the air feel stale, etc). Ventilation is important for indoor air quality. If place is very air-tight for energy efficiency reasons, ask how they dealt with ventilation during energy efficiency upgrades. Old house that hasn’t been upgraded for energy efficiency is likely to breathe better than a modern home that is very “tight” for energy efficiency, as a generalization.

  • Is there good exhaust or window in bathroom? Where does bathroom exhaust to (make sure not exhausting into insulation in attic, etc.)


FOR HOME BUILDING (if building/designing your own home):
