Popped it in the fridge as soon as we got it, and the smell was eliminated super quickly
Having boiled eggs and onions in the refrigerator at the same time can be horrific. This helped!
I have no idea how or why this thing works, but it does! Every fridge needs one of these!
I couldn't believe how powerful it is. Like ten minutes later I opened the fridge and there was zero smell!"
I tried scrubbing, baking soda, vinegar and just about every other smell-killing hack I could find online

Yes - and we take this seriously, so here are the specifics. Cool Egg operates at ≤0.05 parts per million, which is more than 10 times below internationally recognized safety thresholds. It's independently lab-certified by a Bio-detection Center, and it works inside a sealed fridge so you never breathe it.
Ozone has been approved for direct food contact since 2001 and is widely used in commercial food processing, water treatment, and hospital sterilization around the world. The safety warnings you may have seen online refer to high-output room-scale ozone generators - a completely different category of product.
Cool Egg generates a micro-dose of ozone (O₃) which is a natural oxidizer made of three oxygen atoms. When released inside your fridge, it does four things: it chemically breaks down odor molecules at the source (not masking but destroying), it disrupts bacterial cell membranes (reducing E. coli, Listeria, and Salmonella), it neutralizes ethylene gas (the invisible ripening hormone that causes chain-reaction spoilage in produce), and it oxidizes pesticide residues on fruit and vegetable surfaces.
Baking soda and charcoal-based deodorizers are passive absorbers - they sit in your fridge waiting for odor molecules to drift past them, and they saturate within days. They can't kill bacteria, they can't slow produce spoilage, and they can't break down pesticide residues.
Cool Egg is fundamentally different technology. It actively generates ozone that seeks out and destroys odor molecules, reduces bacteria by 99.2%, and extends produce freshness by up to 2–3x. It's the difference between a sponge sitting in the corner hoping to catch something and a purifier continuously cleaning your entire fridge around the clock.
No. At ≤0.05 PPM, the ozone concentration is far too low to alter the taste, texture, or quality of your food. You won't detect any difference - what you will notice is that your fridge smells cleaner and your produce lasts significantly longer. Some customers notice a faint "fresh rain" scent when they first open the fridge, which is the ozone doing its job. It disappears in seconds.
One full charge lasts 30 days - the longest battery life of any fridge purifier on the market. It charges via USB-C in about 4 hours.
Cool Egg's 360° air outlet covers up to 3 cubic meters, which means it works in virtually any home fridge - standard, American-style, side-by-side, French door, or even a large chest freezer. Place it on any shelf and it does the rest.
We offer a 30-day money-back guarantee, no questions asked. Try Cool Egg in your fridge for a full month. If you don't notice fresher produce, cleaner smells, and less food going to waste, we'll refund you in full. We also include a 1-year warranty against any defects. Most customers notice a difference within the first 24–48 hours.
