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:
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.
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.
