EPA / OSHA Information

The Food and Drug Administration (FDA) requires ozone output of indoor medical devices to be no more than 0.05 ppm (parts per million).

The National Institute of Occupational Safety and Health (NIOSH) recommends an upper limit of 0.10 ppm, not to be exceeded at any time.

EPA’s National Ambient Air Quality Standard for ozone is a maximum 8-hour average outdoor concentration of 0.08 ppm.

If an ozone air purifier is going to be running while people are present, the EPA recommends the proper settings should be selected so that the ozone level is less than 0.08 ppm.

PRO-4 Ozone Generators

For example, the PRO-4 operating for only 15 minutes every hour with the ozone output turned to it's lowest position, will effectively treat a small room approximately 12' by 12' for extended periods of time, without exceeding the recommended ozone level.

For best results the ozone generator should be mounted as high in the room as practical. Ozone is heavier than air and it will eventually fall to the floor.

Air circulation is an important factor in how effective ozone works. For large areas, an oscillating fan should be placed next to the generator to help circulate the ozone throughout the room.

If the room is larger, these run times, or settings, can be increased accordingly. A simple test is to let your nose be your guide. Residual ozone becomes apparent to sensitive humans in the range of .01 - .03 ppm. or well below the permissible levels for continuous exposure.

If you can detect a strong smell of ozone, from 8 to 10 feet away, reduce the settings, or run it for less time. Detecting only a faint smell or none at all is a nice safe level.

There are numerous applications for ozone generators where people are not present and thus ozone levels are not necessarily of concern.

For example, the FM-2, or any of our other machines can be operated on their high settings continuously in an unoccupied basement to kill mold and mildew, or get rid of objectionable odors.

The FM-1, FM-14 or the PRO-8 should not be used in occupied spaces, unless that space is quite large, like a church or a barn.

For situations where heavy odors have built up in a room, we recommend setting the unit to high out put, shut the doors and windows, and let it run continuously for 3 or 4 hours while you and the pets are out of that room.

After the allotted time, turn it off, open the windows, and air out the room until the ozone has dissipated.

None of the ozone generators require expensive filters. A small fan filter is supplied with every unit and simply needs to be washed occasionally. The ozone plates located inside the generator should be cleaned with soap and water every 2 or 3 months, and replaced about every two years, or more often if there is a noticeable drop in ozone output. The replacement cost of these plates is from $10.00 to $14.00 each depending on the model.

CA. Residents note: Ozone generators are no longer allowed to be shipped to California residences, pursuant to AB 2276 (Air Cleaner Regulation) . If you would like to purchase one of our ozone generators in California for an industrial application like mold and mildew remediation or odor removal in unoccupied spaces, contact us for one of our industrial supply outlets near you.

Please Remember: All Ozone Generators, regardless of manufacturer, are an electronic appliance containing electrical parts and connections. Your generator will become damaged, your warrantee voided, and the ozone output lessened if immersed in water or operated when humidity (moisture in the air) is above 60%. Lowering the humidity can often be accomplished by simply running a dehumidifier or air-conditioner in the room to be treated.
