How do you know this is effective?
Bought unit to clean veggies and to make a disinfectant solution since the COVID pandemic. Other brand disinfectants are all gone. Also bought a Hanna Instruments test kit and the SenSafe test strips to measure the dissolved 03.<br /><br />Ran a couple experiments at the 10min setting(#5) in1000ml and 400ml of tap water. Both showed low 0.4 to 0.0 PPM of 03. Ran the 1000ml twice so for 20mins and still not a trace of dissolved 03.<br /><br />Contacted the manufacturer and no reply.<br /><br />This is a big buyer beware. Especially if you think your solution is now killing bacteria and viruses. Just because this device bubbles in the water it is no guarantee you are getting a decent ppm of 03. The recommend levels for disinfection is any were from 2-4ppm. I got no were near this. Plus free 03 in the air in a hazard for breathing. We got asthmatics in the house so this purchase will go into the never again column.
