Basement Crawl Space Ozone Treatments

Ozone Generators for Basements and Crawl Spaces: How MaxBlaster Ozone Machines are Used to Make Dingy Spaces Fresh Again.


Since 2008 we've helped thousands of home and business owners successfully use our MaxBlaster ozone generators to deodorize and disinfect basements and crawl spaces. This is one of the most common applications for our ozone machines. Whether you are an individual looking to treat your own property, or you are a business owner providing professional cleaning services, we can show you exactly how to perform ozone treatments like an expert. Contact us for custom recommendations based on your specific project needs.


Basements and crawl spaces are among the most common ozone treatments. These areas are often prone to dampness, mold growth, and musty odors, which can impact indoor air quality of any home or business. While traditional methods like ventilation and dehumidification can help to some extent, ozone generators are a proven solution for proactively eliminating odors, mold, and other contaminants in these spaces. In this article, we will explore ozone generators, their benefits, considerations, and their role in improving air quality in basements and crawl spaces.

Understanding Ozone Generators

MaxBlaster ozone generators produce ozone (O3) gas, a highly reactive form of oxygen. Ozone has powerful oxidizing properties, which make it effective in neutralizing and eliminating a wide range of airborne pollutants, including bacteria, viruses, mold, mildew, and odors. Ozone molecules work by breaking down and destroying these pollutants at a molecular level, leaving behind clean, fresh air. No chemicals or harsh residue.

Benefits of Ozone Generators in Basements and Crawl Spaces

  1. Odor Elimination: Basements and crawl spaces are often plagued by musty and unpleasant odors caused by mold, mildew, and stagnant air. MaxBlaster ozone generators can effectively neutralize these odors by oxidizing and eliminating the organic compounds responsible for the smell, leaving behind a fresh and clean environment.

  2. Mold and Mildew Control: High humidity levels in basements and crawl spaces create an ideal breeding ground for mold and mildew. MaxBlaster ozone generators can help control and prevent mold growth by destroying mold spores and inhibiting their reproduction. However, it is important to address the underlying moisture issue to fully resolve mold problems.

  3. Improved Air Quality: By eliminating pollutants and contaminants, MaxBlaster ozone generators significantly improve indoor air quality in basements and crawl spaces. This can have a positive impact on the overall health and well-being of the occupants.

Considerations When Using Ozone Generators

While ozone generators offer several benefits, it is important to consider the following factors:

  1. Ozone Safety: Ozone generators should be used with caution as excessive exposure to ozone can be harmful. It is important to follow our guidelines. Occupants should vacate the area being treated and allow sufficient time for ozone levels to dissipate before reentering.

  2. Stop the Source: Before using an ozone generator, it is advisable to address any underlying moisture issues, leaks, or ventilation problems that will help achieve better long-term results.

Treatment Tips

We encourage you to consider the following tips & recommendations for athletic apparel sterilization:

  1. Dehumidifier: Humidity and moisture is the ozone killer. Not only does high humidity/moisture reduce the potency of the ozone treatment, it can have negative impacts on the machine itself. We recommend using a dehumidifier prior to running the ozone machine if the property is higher in humidity/moisture. The lower the humidity, the stronger the ozone will perform.

  2. Machine Placement: Do not run the ozone machine on the floor. Place the machine higher in the room if possible. For basements, make sure the machine is placed at least at a table top level. Ozone is heavier than oxygen so it tends to go downwards. You may place fans in the basement to help move the ozone around and encourage it to go upwards. For crawl spaces, place the ozone machine near the entry way or a window that is open a couple of inches. Ideally, you want the ozone machine to be breathing the cleanest, driest air to convert into ozone.

  3. Vapor barrier: Crawl spaces with dirt or porous floors may be difficult to treat with ozone. The goal is to allow the ozone to reach the highest possible concentrations. If the floor is porous, the ozone may get diluted as it seeps into the ground. Use a vapor barrier to help trap the ozone in the crawl space and reach the highest possible concentrations.

  4. Run Times: The length of time to run the ozone machine depends on odor degree, property size, strength of ozone machine, and the number of ozone machines being used. Follow the MaxBlaster Run Time Chart (included with purchase or download on the INFO page of our website) for a good idea of how long to treat your space.


For the average homeowner treating their own property, we recommend our PRO Edition machine as it is the best overall combination of strength and durability. Professional companies may want to consider using multiple machines to speed up the treatments and allow the ozone to spread more evenly across larger spaces. Our strongest machine, the PRO-G Edition, is better for those experienced with operating and maintaining high-performance equipment.


MaxBlaster ozone generators offer an effective solution for improving air quality in basements and crawl spaces. By eliminating odors, controlling mold and mildew, reducing allergens, and enhancing overall air quality, our ozone machines contribute to a healthier indoor environment. However, it is essential to use ozone generators responsibly, following safety guidelines, and addressing underlying moisture issues for optimal results. When used correctly and in conjunction with other maintenance practices, ozone generators can provide a fresh and clean environment in basements and crawl spaces, enhancing the comfort and well-being of homeowners.
