It will just give you a sore throat.
Technical data on testing:
The Berry Breeze (originally the Ozonator $50) generates ozone through a high voltage corona discharge. I measured the voltage at just over 4000 volts.
It puts out a peak 0.8 ppm ozone in the first 48 to 52 minutes; solid green LED.
It then goes into stand by for 195 minutes; blinking green LED.
Then it runs for 8 minutes. Thereafter in 203 minutes it generates ozone for 8 minutes or 8/203 (4% of the time).
This is why the 50 hour batteries can last for months.
The 1/2 life of ozone at 0 degrees C (32 F) is only 300 seconds.
The total time to decay back to stable O2 oxygen is 15 minutes.
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.
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. "
Is FALSE. Did you notice the 3 typos?
To kill bacteria you need .25 to 2.29 ppm for 20 minutes.
To kill viruses you need .2 to 4.1 ppm for 30 minutes.
To kill mold you need 3.0 to 5.0 ppm for 60 minutes.
To kill fungi you need .02 to .26 ppm for 1.67 minutes.
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.
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.
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
Ozone density is 2.14 kg/m^3 or 2.14 g/l or .00214 mg/l = 1 ppm.
The unit generated a total .885 mg of ozone in the 48 minute runtime, which calculates to 1.138 mg/hour.
This is 4.5% of the published 25 mg/hour for the "Ozonator" identical unit.
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.
I noticed that during all testing I had an irritating sore throat that lasted for hours.
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.
