USING THE PURIFY FUNCTION

The purify setting is a powerful part of your purifier.  It engages the ozone (O

3

) generator in the unit. This is a 

great solution for mold and strong odors. The PURIFY (O3) is not designed to be left on all the time, but 

rather to be used for short periods or with the timer, to cleanse unoccupied areas.  When used for mold 

eradication in musty moldy basements, set the timer on the unit so that it runs for 2 or 3 hours on highest fan 

and purify settings, then leave the area or shut the area off by closing the door. Set the unit to shut down at 

least 30 minutes prior to your return. These 30 minutes allow ozone (O

3

) to turn into oxygen (O

2

) rich air. 

See instructions below when used to overcome odors.  As a good rule of thumb, when you no longer smell 

the odor and instead smell the ozone (O

3

), the ozone has done its job and you may turn the ozone off and 

return the unit to normal settings.

Press “Purify    ” or “Purify     ” to adjust the level of activated oxygen (O

3

).  There are five stages. Use the 

following chart to determine the proper setting for the area to be purified.  Reference the chart below for 

recommended purify levels.  These levels are considered safe for short periods of time when the room is 

occupied.  

HOWEVER, INDIVIDUALS WITH ASTHMA OR ANY RESPIRATORY OR LUNG CONDITION SHOULD NOT 

BE IN THE ROOM WHEN THE PURIFY FEATURE IS ENGAGED

IS OZONE SAFE ?

Yes, but moderation is the key. Use your nose – if you can smell ozone, it is time to turn it off. 

The following guidelines should be strictly adhered to: 

Set the Purify (O3) Level properly for the room size.

Run the Purify (O3) feature for short periods of time.  Do not continuously run the Purify feature.

Individuals with asthma or any respiratory or lung condition should not be in the room when using

the Purify feature.

Only set the Purify Level on higher settings when the room is unoccupied (people and animals) to

eradicate odors [cigarette, pet, cooking odors, etc.]

Use the (O3) Timer to run the ozone safely on higher settings in unoccupied setting and allow the

unit to shut down this PURIFY feature automatically.

When someone in the room is using bottled Oxygen, you should not use the purify (03) feature.

Ozone in very high concentrations can be irritating to mucous membranes and the respiratory 

system. Relatively low levels of ozone may cause chest pain and shortness of breath.  Ozone may worsen 

asthma and compromise the ability of the body to fight respiratory infections.  

Please refer to User’s Guide for additional instructions on the Purify Function, as well
