About SD International / OdorFree Ozone Generators

The CEO and founder of SD International, Inc has been involved in the design, ozone generator manufacture and distribution since 1998. The OdorFree line was developed to provide a high quality product at an affordable price for commercial users and consumers. These units had to be very easy to operate, portable and easy to maintain in the field. Another requirement was that the products also had to be manufactured to the highest standards in order to carry a 5 year warranty. As a result, SD International is now the industry leader and considered an authority on removing odors at their source through ozone oxidation.

We are headquartered in North Florida but have warehousing in five locations around the US on both the east and west coasts. This allows SD International to insure prompt delivery of the OdorFree ozone generator nationwide within 2 business days, at no charge to the buyer.


Ozone generators have been used for decades by professionals to remove odors from hotel rooms, apartment buildings, homes and offices. Different technologies have been tried by ozone generator manufacturers over the years. Corona discharge became the dominant form of ozone generation over ultra violet light because of the ability to create greater amounts of ozone. And ceramic became the most widely used plate material, because of the difficulty of cleaning mica plates, and cost and complications of replacing them.

This was an important consideration because all ozone plates will build up a film on them over time. This film steadily reduces the ozone output the more times the product is used. So the OdorFree uses ceramic plates with a design that makes them very easy to remove when they need to be cleaned. Years of experience in ozone generation manufacturing and field testing has proven that the OdorFree is the most user-friendly, most reliable and the easiest to maintain.


Designed and tested in the USA, the OdorFree ozone is built to commercial-grade specifications. Like most of your appliances today, from telephones to computers to microwaves, the OdorFree is manufactured in a plant that operates under ISO 9001 certification located in China. ISO 9001 is an international quality and inspection standard that requires certified factories to have documented, repeatable manufacturing and testing processes to ensure the highest quality products.

All major appliance companies require that the manufacturer be certified by this international body. The factory that manufactures the OdorFree also makes appliances for major companies like General Electric, Hitachi and others. Their reputation, certification and years of experience are the reasons the founder of SDI selected them many years ago to be the ozone generator manufacturer.

No matter where the final product is assembled, nearly all electrical components for ozone generators are manufactured in Asia. The OdorFree is assembled and tested to the highest ISO standards in close proximity to the source of electronic components. This ensures that every OdorFree ozone generator can be offered at a price that provides the greatest value to the buyer.
