Things to consider when buying an ozone generator for mold

The most crucial factors to look at when choosing an ozone machine for mold include:

  • Hold Function and Timer: The hold function allows you to run the machine for prolonged hours. That is crucial if the generator has a fixed running time. A timer allows you to set the unit to the preferred time and leave the room for treatment. It will then turn off automatically once the timer runs out.
  • Ozone output capacity: The market has both high and low-output ozone generators. In that case, choose a machine based on the speed at which it releases ozone. Ideally, consider one that emits a higher O3 output because it will fill and treat a room faster.
  • Remote Control: When the mold killer machine has a remote control, it will allow you to adjust the ozone output and fan speed anytime. That is crucial because you can control the unit while it treats a room.


The best way of eliminating mold at home is to use an ozone generator. But before you buy one, ensure you are getting the best ozone generator for mold.

Consider things like timer function, O3 output, and room coverage when purchasing the unit.
