Diffusers and essential oils can be helpful before, during and after remediation. The best diffusers for mold challenges do not use water, since water would fuel the growth of mold. I have had good experience with these two diffusers:
TheraPro by Young Living
Aroma Ace by Diffuser World
These are basically the same diffuser which develop a specific output that has been tested to be effective when used in mold contaminated environments. I personally use this model of diffuser for my home and family.
TheraPro is only available in the United States and only through Young Living.
