Top 7 Best Air Purifiers for Basement Smell And Mold

Written By: Dr Fahad Yasin

To kill mold entirely and prevent it from growing in your home, you must keep the humidity level between 30% and 50%. If your humidity level is above 60%, it is better to use a dehumidifier instead of an air purifier.

But if you have mold and your humidity level is back to normal, you can use an air purifier to eliminate mold and mold odors which are also the primary basement smell source.

Here are brief summaries for each of the air purifiers recommended for basement smell and mold:

Remember that air purifiers with filters only won’t help kill active mold that’s already current on surfaces. However, they are still a terrific method to prevent the spread of airborne mold particles.
But for complete elimination, air purifiers must also actively emit ions to fight them on surfaces.

Usage Recommendations for Air Purifiers in Basements

These are just recommendations for better air purifier usage; you can ignore them.
  • Ensure proper airflow by not obstructing the purifier.
  • Position the purifier strategically, either close to the pollution source or in the middle of the room.
