Four tips on how to get the best results

The Best Air Purifiers:

1. Get your basement properly ventilated

Mold thrives in basements due to poor ventilation. This enables mold to breed for long periods because dampness provides conducive environments. So, in order to ensure your air purifier keeps your basement mold-free, you need to take care of your ventilation. Hire a qualified constructor to inspect your basement and provide a good ventilation design.

2. Buy a dehumidifier

Why do you need a dehumidifier? Because it eliminates excess humidity in your basement. A dehumidifier makes your basement unsafe for mold breeding by making it too dry for survival.

3. Hire a qualified constructor to inspect your basement for mold

Mold spores are microscopic organisms and this enables them to hide between thin wall cracks and inside furniture. No matter how much bleach one might use, there’ll still be certain spots with mold spores. So, how does one prevent regrowth? By hiring a qualified building constructor to do a thorough mold inspection.

4. Don’t store damp items in your basement.

Your air purifier will deliver the best results when you maintain low humidity and good ventilation. Despite owning a dehumidifier, it’s wrong to store damp items inside a basement. Doing this increases the amount of humidity and mold spores.
