Info: On-Demand Ozone Water Maker and Sprayer, Model SB-100

Aqueous ozone or ozone water is a safe and effective method of both cleaning and sanitizing many household items. This handy household appliance produces it very quickly and easily using just ordinary tap water, and can save you thousands of dollars in conventional cleaners over the years!

Product Notes:

Now more than ever, it's important to keep all the surfaces of your home that people might touch clean and germ-free, especially when there's visitors (both before and after they arrive). There may also be many household items that regular cleaners cannot fully clean (of food stains, for example) without leaving unwanted deposits.

"Aqueous Ozone" may sound a bit scary, but it's really just ordinary water molecules that have been 'zapped' with a small electric current to temporarily remove their single hydrogen atom and replace it with an additional oxygen atom to form new ozone molecules (O3) suspended in the water that are exponentially better at cleaning and disinfecting than the H2O is alone.

Ozone's so good as a disinfecting cleaner, in fact, that it started being used commercially to clean the laundry in hospitals and hotels, which was soon followed by several brands of home laundry machines that are now sold all around the world, such as the PureWash Pro laundry machines offered by the same distributor that supplies us with this spray bottle. It even features in some cities' wastewater plants.

Dozens of academic studies and independent lab tests have shown aqueous ozone is not only effective at eliminating odours after about 30 seconds of contact, but also mold and 99.9% of the common germs which make people sick, including E. coli, Staph A. (Staphylococcus aureus), Candida albicans, and bacteria like listeria, Pseudomonas aeruginosa, and salmonella.

A Safer Sanitizer - Just Add Water

This small appliance, which is very easy to operate, is able to generate aqueous ozone instantly on demand using just ordinary tap water, by using a special electrode in its head which uses actual diamonds and a DC current from a rechargeable battery to electrolyze it. (Electrolysis involves passing an electric current through a substance to effect a chemical change.)

The cleaning solution it emits remains potent or stable in that form for five minutes after squeezing the trigger, which gives plenty of time to follow up by wiping the surface with a sponge or cloth, if desired. (You don't even need to wear gloves while using it - although ozone water can shred viruses and bacteria, it's harmless to human skin. You should avoid inhaling the fumes, however.) After that, it reverts back to ordinary harmless water.

Of course, like any device operated by a rechargeable battery, it needs to be charged up the first time you use it, which takes about 4 hours with the USB charging cable (included) plugged into either a computer or a USB phone charger. Once it's fully charged, it can produce up to 140 ounces of aqueous water before needing recharging, and its useful battery life is rated for up to 500 charges.  (In addition, in some cases, if it does not work properly the first time its used, you may need to 'prime' the electrode again by adding some table salt to its water reservoir, as explained on p. 7 of the user manual.)

EnozoHOME vs. EnozoPRO

Enozo produces two versions of this device: a Home version, which also goes by the name "O3 Waterworks Sanitizing Spray Bottle", and this commercial or Pro version (which also goes by the name "Enozo3 Aqueous Ozone Spray Bottle - SB100"), which admittedly costs about twice as much.

However, once the differences between them are clarified, it should be apparent this version is ultimately the better value since it will last so much longer (for a home user, the expected lifespan for the home version is 3 to 5 years, while the Pro version would likely last several decades for typical home use), and displace the need for well over $10,000 more in conventional cleaning solutions, over the life of the product (as shown in the table below).

Moreover, if you are going to use it for commercial purposes (such as at a restaurant, hotel, daycare, veterinary clinic, etc.), it's important to note that although both versions have a 7.4 V Li-Ion rechargeable battery pack, the Pro version's does not need to be charged as often, which can be an important consideration if you're using it constantly. The Home version needs recharging about every three of its smaller 'tank-fulls' (i.e., after 30 ounces of 'squirting'), whereas the Pro version can last up to 10 tanks of water before needing recharging (i.e. after up to 140 ounces).

Suggested Usage:

Aqueous ozone can be used wherever you might use regular spray cleaners. You can even spray food with it to prevent mold and bacterial growth.

To clean and sanitize hard non-porous surfaces, after charging the battery and filling the reservoir as detailed in the user manual, simply hold the spray bottle about 6 to 8 inches from the surface you want cleaned, and press the button on the front of the unit below the head to spray. Spray evenly across the surface until it appears wet. For 99.9% effectiveness against common pathogens, allow the solution to stand for at least 30 seconds. Then either just allow to air dry, or wipe it off with a clean cotton or microfiber cloth. No rinsing is necessary, as it leaves no residue. While spraying, the blue indicator will light up when the unit is operating properly.

Cautions & Maintenance Issues:

Do not spray the solution toward anyone's eyes. In case of eye exposure, rinse affected eye(s) thoroughly with regular clean water for 5 to 10 minutes. If irritation persists, seek medical attention. Use only in a properly ventilated area. If you experience respiratory irritation, or if an overly strong odor of ozone is detected, discontinue use immediately.

Use only clean, potable water to create the ozone solution or to rinse the water reservoir (and be careful not to overfill it), and do not add any cleaning chemicals into the water reservoir. The exterior of the unit can be cleaned with a soft cloth; do not use harsh or abrasive cleaners (use this solution, instead - just spray it onto a cloth), and do not immerse the unit in water or drop it so as not to damage the electronics. And as with any other object primarily made of plastic, do not expose the sprayer to extreme heat or open flame.
