Sodium Hypochlorite Generator Multi-Purpose Cleaning Supplies Generator, Chlorine Testing Strips Included

This product is pretty solid. The weak point is that it would have been nicer to have more detailed instructions, like a table indicating the process and the resultant strengths, but you can do that work yourself with some test strips and a little google. Get yourself chlorine test strips so you know how strong your final solution is. Following the given instructions gives you about 200ppm, which is enough to make a good bleach disinfectant spray for cleaning hard surfaces. Give it more salt and a longer processing time, you should be able to get a solution up to 1% or so, which approaches strong enough to use as bleach. You'll probably need to use 2-3x as much to get the same result as commercial store-bought bleach, but that's not a problem because this amount costs you less than a penny. Although the cost savings could be huge if you're a person who uses a lot of bleach, the biggest plus here is that the bleach solution you get through this electrolysis process will be much safer than anything you buy at the store. Commercial bleach is stabilized with caustic lye, tends to be pretty nasty stuff. Make no mistake, this is chlorine, but the product you make with this process will not be considered "hazardous", unlike store-bought bleach. Also unlike the harsher chemicals in commercial bleach products, these are completely safe for the environment. What you make will decay back into ordinary salt water within a couple weeks. As a side benefit, you can also use this device to make Hypochlorous Acid, with the small addition of an acid to the process. Something like citric acid is best, but you can also get a decent result with acetic (vinegar) acid. This is useful as both a disinfectant and an antiseptic for topical purposes; and also is something that could be sprayed on fresh produce before rinsing to harmlessly disinfect any surface microbes. All in all, this device, while inexpensive, offers very high value for the price, as long as the person using it is willing to do a little bit of research to ensure they're using it safely and effectively.

After reading about hypochlorous acid, I purchased this to simplify my cleaning routine. It's non-toxic when used properly, cheap and easy to make, and most importantly, very effective. I work in an environment that is germ-infested (lots of children around), and I can spray this stuff on anything without worrying about hurting someone. I also use it as hand sanitizer and a face refresher. I make 800mL at a time in a medium-sized Mason jar. I use reverse osmosis water from the grocery refill station with 1tsp each of iodine-free salt and vinegar, then let the device do its thing for about 2 hours in the garage (some chlorine off-gassing that could be dangerous). The concentration turns out to over 200ppm and pH of about 5, which is effective to disinfect in about 30 seconds or less. I have it stored in amber colored spray bottles away from heat and sunlight (they cause the solution to become ineffective quickly) and the leftovers go in the fridge (label to prevent drinking). There is a slight chlorine odor when spraying and using. It's safe to use on anything, including your skin and pets. DO NOT INHALE FUMES when transferring liquid!

A good basic unit. Overall it seems to work quite well, and produces the same hypochlorous acid that the expensive units do at a fraction of the price. The included instructions aren't quite so insightful, so from my research here is what I came up with. 100ml of water, 1ml of vinegar, and 0.25g of salt. This should be a neutral to slightly acidic PH. If your water starts out more basic, you will need to add more vinegar. If your PH is neutral to slightly acidic, you will get more hypochlorous acid. If it is more basic, you will get more hypochlorite (aka bleach). I premix a bottle with a bunch of vinegar and salt measured out into it with an eye dropper with a 1ml mark on it. Makes it quick and easy. The one star knock off is that it is not built great and you can see that the plates are a bit loose inside, but it does work. Of course verify everything yourself and be cautious with any chemistry you conduct on your own. Test strips are vital when getting started.

So far, so good. This is a review in progress... The goal is to generate a whole gallon of useful disinfecting chlorine bleach; sodium hypochlorite (NaClO), at a concentration of at least 0.5~1.0% (5~10 g/L; 5,000~10,000 ppm). Hopefully, I can achieve even higher concentrations. First, My A.I. buddy Grok recommends a sodium solution (salt content) of 19–38 g/L, which translates to 4~8 tbsp per gallon, or 1/4 to 1/2 cup of table salt, non-iodized if available. I will be experimenting with 1/4 cup, 3/8 cup, and 1/2 cup of salt per gallon of warm water in my experimentation. I have received my first USB chlorine electrolysis generator in the mail today, and so far it is working well. I have ordered a second unit, as well as a magnetic stir plate, stir bars, which should be ariving in the next couple days. The generator is only pulling 0.5~0.6 Ampres of current with the 1/4 cup solution, and to speed things along I really might as well buy a second unit. The stir bar will help keep the very fine bubbles suspended in the water for longer (3 to 10 times as long) to really absorb into solution, drastically reducing the time to achieve final product. I am running the USB generators on a battery backup powerbank rather than plugged directly into a wall charger, as it is absolutely forbidden to plug any electrical device submerged into water into a wall outlet. Watch youtube videos for USB wall chargers catching on fire, creating an electrical fire in your home, and electrifying the water you are working with. This is because most USB chargers reference to ground, and not properly isolated floating voltage, which encourages electrical arc and short circuit. It happens a lot. So, a battery bank should be used. I will be using a battery bank with (2) USB type-A ports. Until I receive the rest of my order, this concludes my my review in progress.

These work fantastic and deliver as they state. I have 2 of them and make cleaning solution.

Works as it should
