It allows you to place a source of negative ions and ozone in just about every room and section of the house, at a price that is comparable to a larger, single-unit system. Even a very powerful ozone and negative ion air purifier can only ionize a single room anyway, and it will probably not be able to provide ozone purification for the whole home. Strong Odors . However, they are not as effective against strong odors as more powerful ozonating air purifiers, such as Spring Air purifiers . Spring Air purifiers are more effective against odors due to the fact that they produce higher amounts of ozone.

In which case, an air purifier that produces a higher concentration of ozone is best. If the odor and pollution level is strong enough, the odor and the ozone will cancel each other out, so the ozone concentration will not become excessive, even with a more powerful unit. You can tell if the ozone level is getting close to becoming too high by the smell. The smell of the ozone will become overpowering and obnoxious at a level quite a bit lower than the concentration where it can become a minor lung irritant. In which case, the Surround Air units will be more effective at removing the smoke itself for small areas, and somewhat effective at removing the odor from the smoke, since they produce high levels of negative ions, and moderate amounts of ozone.
