The following should be considered when buying an ozone generator:
- Whether the ozone concentration that the product can achieve is suitable for the size of the space to be treated.
- Life-span of the ozone plates or tubes in the machine.
- Whether it is convenient to operate (whether there is ozone concentration setting, timing function, etc.)
- Whether it is convenient to maintain the machine.
- Its noise level.
- Whether the parts and components of the machine are resistant to ozone or not.
