Sizing recommendations for mold and mildew reduction

Mold, mildew, and fungus can be oxidized with ozone. Crystal Air ozone generators reduce or eliminate the ability for the exposed mold, mildew and fungus to grow as well as oxidizing the existing mold. Mold and mildew grow in dark and humid places where there is a lack of fresh oxygen. In all cases the moisture and humidity in the walls, floor etc., must first be removed or solved permanently to effectively eliminate the problem mold and odor. Once moisture is removed, all visible mold and mildew should be removed, then a shock treatment procedure can be preformed lasting for 24-72 hrs. A small ozone generator can be used to help control continuous mildew problem odors if they persist.

Recommended equipment:  
PRO 9,000-1
For commercial mold treatments jobs you should use .5-2 g/hr ozone for every 100 sq/ft, depending on how fast the job needs to be done and how bad the problem is. With .5 g/hr / 100 sq/ft you should treat for 1-2 days +, with 2 g/hr / 100 sq/ft it should only take about  6-12 hours.
PRO 450, PRO 970, PRO3400-1, PRO 9,000-1
For the do-it-yourself home owner, the treatments can be done one room at a time to allow the use of a much smaller unit. Just calculate the size of your largest room to come up with the size of unit that you will require. Also most home owners are not in as much of a rush to do the job, if this is so you can probably do the job with 1/4 of the above recommended ozone production. 
 
Application Procedures:
Site preparation:
1. Mold usually occurs because of a leak or humidity problem. This leak or humidity problem must be fixed or solved or the problem will continue to persist.
2. All damaged or rotten items should be removed from the area as well as any carpet, wall board, or other building materials that are to be replaced. 
3. Thoroughly clean all areas possible,  remove any visible mold, mildew, etc.
 
Ozone application:
Place the ozone generator in an area that will provide the best circulation and distribution of the ozone. Run an extension cord from all generators to the receptacle closest to the exit door. Use auxiliary fans to help with circulation, this will also help to drive the ozone into the pores of the materials. Turn the generator/s to full output and to the on position. Leave the premises and lock all entrances. Allow the ozone application to operate for the above recommended time. If the problem is especially bad increase the amount of ozone used or the length of the application accordingly. Upon returning to the premises, turn off the ozone generators by unplugging the extension cord or use timers available at your local lumber store for less than $20. Leave the premises and lock all entrances. Allow the building to sit for 4-8 hrs, this allows the remaining ozone to convert back to oxygen and reduce ozone exposure.
Special notes on mold, mildew, etc.
- Crystal Air ozone generators help to reduce or eliminate the ability for the exposed mold, mildew and fungus to grow. However mold and mildew grow in dark and humid places where there is a lack of oxygen and is usually caused by a leak, improper drainage, or high humidity. In all cases the moisture and humidity in the walls, floor etc., must be removed permanently to effectively eliminate the problem.

- In all cases you must do a test to know the effectiveness of your ozone application. If you do not test before and after the treatment you will not know whether it was effective. This test should be done on a regular schedule to ensure that the contamination does not return.
