This ozone generator won't kill any mold.
This ozone unit won't kill any mold.<br />It will just give you a sore throat.<br /><br />Technical data on testing:<br />The Berry Breeze (originally the Ozonator $50) generates ozone through a high voltage corona discharge.  I measured the voltage at just over 4000 volts.<br />It puts out a peak 0.8 ppm ozone in the first 48 to 52 minutes; solid green LED.<br />It then goes into stand by for 195 minutes; blinking green LED.<br />Then it runs for 8 minutes.  Thereafter in 203 minutes it generates ozone for 8 minutes or 8/203 (4% of the time).<br />This is why the 50 hour batteries can last for months.<br />The 1/2 life of ozone at 0 degrees C (32 F) is only 300 seconds.<br />The total time to decay back to stable O2 oxygen is 15 minutes.<br />In a standard 21 cubic refrigerator (.61 cubic meters) that 8 minute run time generates only 0.4 ppm, for a few minutes.  This is not enough ozone concentration to kill anything.<br /><br />Therefore the statement: "Because Berry Breeze slowly release O3 into your refirgerator, food decompostition comes to a grinding hault - preventing them from molding and rotting. "<br />Is FALSE.  Did you notice the 3 typos?<br /><br />To kill bacteria you need .25 to 2.29 ppm for 20 minutes.<br />To kill viruses you need .2 to 4.1 ppm for 30 minutes.<br />To kill mold you need 3.0 to 5.0 ppm for 60 minutes.<br />To kill fungi you need .02 to .26 ppm for 1.67 minutes.<br /><br />So I put the unit into the crisper drawer: this works much better.  The peak ozone was 2.5 ppm and decayed to 0 in 4 minutes, enough to kill fungi, but nothing else.<br /><br />Then I put the unit into a 5 gallon bucket (21 liter) and sealed the lid.  This produced 19.7 ppm.  The decay time was 100 minutes, because it was airtight.<br />The only way to kill everything is to put the unit in a small airtight container, like the Rubbermaid Commercial Products, Plastic Space Saving Square Food Storage Container for Kitchen/Sous Vide/Food Prep, 12 Quart, Clear<br /><br />Ozone density is 2.14 kg/m^3 or 2.14 g/l or .00214 mg/l = 1 ppm.<br />The unit generated a total .885 mg of ozone in the 48 minute runtime, which calculates to 1.138 mg/hour.<br />This is 4.5% of the published 25 mg/hour for the "Ozonator" identical unit.<br /><br />I also tested the dissolved ozone in water in the refrigerator using 0 to .5 ppm test strips: after the full 52 minute runtime, in the refrigerator crisper drawer, it measured 0 ppm in an open glass of water.<br /><br />I noticed that during all testing I had an irritating sore throat that lasted for hours.<br />All testing done in a sealed refrigerator or sealed bucket.  It only takes a brief inhalation when snapping the cover on to start the ozone to cause a sore throat.<br /><br />Ozone senor used:  ME2-O3 (0-100)  21K19D-0136
