How Long Should Ozone Generators Run?

A7K Air Applications Air-3500 Air-7000 All About Ozone Aqua-8 Water Applications

Our ozone generators are designed to fit a wide variety of applications. Ozone is 3,000 times more powerful, making it a good choice for treating bacteria and other contaminants in air and water. 

Ozone Air Applications

The A7K, Air-7000 and Air-3500 are heavy duty deodorizers designed to oxidize smells, odors and viruses from the air. Using all-natural ozone, the Air Series will eliminate harsh odors leaving the area fresh and sanitized.

Air-7000 Ozone Generator

Follow the guidelines below for shock treating rooms with the Air-7000 and Air-3500. Once the treatment is completed, allow the room to sit for at least 30 minutes before entering. Repeat the treatment if the odor is still present. Keep in mind, the Air-7000 is significantly more powerful than the Air-3500, so treatment times will vary between the units.

Medium Sized Room 1 to 2 hours
Small Room or Closet 30 minutes to 1 hour

Ozone Water Applications

The Aqua-8 can be used to purify water in containers, storage tanks, spas, bathtubs, fountains and wading pools. It can also be used to purify drinking water from well sources or city water supplies, removes undesirable tastes, chemicals, odors and colors caused by iron, copper, manganese, chlorine and organic chemicals such as pesticides, and herbicides. Do not use water from a source that is questionable, such as a stagnant pool of water.

To treat water, place the white or gray diffuser stone into the water container (no more than 4 inches deep). Then, run the unit according to the table below. When the function is completed, turn off the Aqua-8 and allow twenty minutes for excess ozone to dissipate from the water.

Higher output ozone generators are available from A2Z Ozone for well water and holding tanks. Ozone removes excess minerals including iron, manganese, lead, as well as radon and sulfur. View these more powerful MP Series units here.

When operating an ozone generator, please remember to remove people, pets, and plants from the area. Be sure to leave the area being treated immediately and only return once the ozone has dissipated. Under most conditions, the treated area should be safe to return to 30 minutes to 1 hour after the unit stops producing ozone. Treated spaces or buildings should be well-ventilated prior to re-entry.

In case of accidental leakage of ozone, keep the ozone generator in a 
well- ventilated area. 
Ozone generators emit ozone. Do not inhale ozone. 
Ozone generators generate high voltage.
