> Ozone was added to the chamber air inflow in a quantity that was not harmful for humans but representative of higher indoor levels Just in case anyone reads this and is thinking about buying one of the ozone emitting "air cleaners": https://www.epa.gov/indoor-air-quality-iaq/ozone-generators-are-sold-air-cleaners https://www.epa.gov/indoor-air-quality-iaq/ozone-generators-... "The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs"

Maybe they can be used while rooms are not occupied? That said, would there be any wear/damage on items within the room?

    It does much more than airing out. It will completely clear up cigarette smell from an apartment that had indoor smoking. It neutralizes. All the gunk that built up from it, similar to how it degrades rubber.

It will completely clear up cigarette smell from an apartment that had indoor smoking As will surface cleaning and repainting porous surfaces that held the cigarette tar, but without the side effects of ozone like the release of additional VOCs from other materials it reacts with. Either way, completely airing out the space is a necessity.

        You're not going to repaint carpet.
        danans 4y ago
        No, but deep cleaning it with a machine or replacing it are possible.
        thfuran 4y ago
        Possible...and way less convenient and way more expensive than just putting some ozone into the air.

        They are undoubtedly different solutions with very different outcomes. This discussion has been good for laying out the pros/cons.

        Do you seriously leave smelly carpet from previous owners in place?
        Gigachad 4y ago
        If it was visually fine, id rather use ozone to fix it than replace.

Seems a little odd. I guess they mean it's just not acutely harmful? I have an ozone generator. I use it occasionally and never in the same room. It's pretty useful for clearing out odors as long as you air out the space afterwards to help the ozone dissipate.

  > It's pretty useful for clearing out odors as long as you air out the space afterwards to help the ozone dissipate. You can skip a step and clear the odors just by airing out the space. If the odors are of the type and quantity that airing out the space isn't sufficient, the issue to deal with might be the source of the odors. An air filter with activated carbon can also help reduce odors.

    I had an RV which was previously housing mice. After removing and Killz, it still smelled. Two days with the ozone and it was fine after.
    - danans 4y ago
      If it still smelled it is because the waste of the mice remained in the RV. The ozone didn't remove the waste, but probably just reacted with it to neutralize the odor causing VOCs. If you were ok with that state, that's great, but eliminating the source of the odor tends to be more effective way to deal with it.

        It kills off microbes, does it not? We live in a high humidity environment. When we shut up the house and travel for a couple weeks, there's inevitably a high amount of mildew on our return. I have been contemplating running an ozone generator on a timer while we're out of the house for an extended period to combat this.
