Using Ozone to Treat Mold

It is quite well known that ozone will kill mold.  In fact, it can also harm mold spores so they are not able to reproduce.  One word of advice though.  It is always a good idea to be running one of more HEPA filter systems during any kind of mold treatment.  In fact, if you are going to clean away any molded areas, it is good practice to wear a particle filter mask as well.

To answer the question of whether ozone kills mold, the answer is "Yes, it does."  However, if the mold is behind the wall, the ozone will only affect the side exposed to the ozone.

Professionals know the difference between surface or exposed mold and the mold that you cannot see behind the wall.

Basements are more easily treated because they do not have enclosed walls.  

If the mold is visible and accessible, use a 3-4 hour treatment with our 1530G MAXX unit.  You can have the air filters running at the same time.  After the mold has been killed, you can remove it with a HEPA-type vacuum or cleaning products.  

When you find mold, there is always a water or humidity problem.  So, if you really want to solve the mold problem, you must also locate and stop the water source.  In a basement with high humidity, you will need to run a dehumidifier.  If there is a water leak from a sweating pipe or cracked foundation, that needs to be fixed.  Basically, if you stop the water source, the mold will not return and your mold cleanup will be a success.

If there is mold in the crawlspace or attic, this happens because of lack of ventilation or some small water leak.  Attic and crawlspace mold probably requires a profession service.

Finally, once you treat a molded area, continue running the HEPA filters for days after the treatment to get rid of mold spore, HEPA vacuum and dust all areas wearing a mask for extra safety.  Then, plan to use the 1530G MAXX occasionally after the treatment to stay well ahead of the problem.  If the water problem is solved and your treatment successful, the mold will not return.
