    Plasma ionic air cleaner??

    Looking for your input on some kind of ionic air cleaner. Not sure if its a combination of plasma and ions added to the air type of product. A sales guy was explaining an air cleaner device that adds ions to the air. Its creates a Mount Everest environment down at sea level. (Basically is the theory). Its not a u.v light though. Anyone have any input on this type of product? I mentioned the rgf product that puts hydrogen peroxide molecules into the air stream. But he said no,no,no this device is totally different.

    I wonder if he's talking about the Reme Halo? It apparently ionizes the air without releasing ozone (or so I've been led to believe). I'm considering this for a new HVAC install to help clean the indoor air (would likely couple this with a dehumidifying ventilator to bring fresh air into the house).

    There's lots of folks here who are pretty happy with the Reme Halo...

    Couldn't find your brand but a electronic air cleaner does the same thing changes dirt particals charge.

    There are a lot of people who love these. I tried the little desk top display Reme has in my house and noticed an improvement in less dog smells from the 2 dogs.

    There are 4 categories of devices mentioned in this thread:

    1. Classic Photo Catalytic Oxidation devices. Basically these generate a very strong oxidizing agent - hydroxyl ions. Scientific studies on this technology dates back decades. NASA used this technology to remove ethylene from the vegetable garden in the space shuttle in the 90s. How well this technology works in residences with typical levels of VOCs is not conclusive. At extreme VOCs levels these devices can be effective but at levels found in residences/business I have not seen convincing data. Here's a link to how this technology works:
    https://www.explainthatstuff.com/how...iers-work.html

    Here's a very good science overview of this technology: Note sciency and nerdy:
    http://www.mdpi.com/1420-3049/21/1/56


    2. An off shoot of this technology is PCO that generates primarily hydrogen peroxide. RGF/Air Osasis and a number of other companies used this approach. Unlike classic PCO the reactions takes place in the living space not at the catalyst. Also this approach, like classic PCO can generate a lot of ozone, a lot more than the manufactures like to admit. Not much independent testing. The companies that do the testing provide results that don't scale well to real world living spaces.

    3. A number of companies (RGF/Air Osasis and more) ionize the hydrogen preoxide. The claim being that the ions add an extra kick by getting particulates and VOCs to stick together resulting in bigger particles that will drop horizonal surfaces and/or can be collected by air filters - merv 10+. Not a lot of good evidence that this approach offers significant help in real world conditions.

    4. Pure Ionizers, which is what I think was the original inquiry. A couple of companies are - Global Plasma Solutions, Air Plasma and Atmos Air.

    I've been researching all the above with diminishing enthusiasm, but I haven't given up yet.

    The only way to know if this stuff works is objective testing using instrumentation. I believe a lot folks confuse the smell of ozone with clean air.

    Fresh air intake, as Teddy in constantly reminding us, does work.

    Bake outs are another approach that can be effective see:
    https://www.google.com/search?q=bake...hrome&ie=UTF-8

    When researching stick to independent science articles. Beware of science PR spin used by manufactures.

    To be continued....

    According to Kenneth, so far, the prototype Molekule for whole house works for him and his wife. IMO it's because it has far more surface area for a reaction, he has less than or of an easier VOC to break down, and it's psychological (he wants it to work).

    As there is not more than one of these in use, it's very difficult to quantify/qualify.

    Unless he has taken before and after test with a PID meter or gas chromatography/mass spec lab test I don't know how anything conclusive can be determined as for as VOCs are concerned. As I recall he installed new duct work before installing the MoleKule. Too many changing variables and a lack of objective testing to reach a conclusion for TVOC levels.

    Also as I recall, according to Kennith, his complaint was mold and dust. Biologicals are much easier to destroy with PCO technology than VOCs. All it take to kill a bug is one broken carbon/hydorgen bond. It takes a lot more work to break all the C/Bonds with VOCs.

    I'm in the middle of doing in house testing, as I write, with the generous help of MoleKule. I will provide an update after testing and when appropriate.

    I've installed 10 of these on the air handlers in the Casino and so far, have been pleased. Floor personnel say they go home and clothing does not stink of cigarette smoke! I think that says a lot.

    We also do a 20% out door air mix which helped a lot, but the coup 'd gras was the ionizers...

    Thanks for the report.
    Cigarette smoke is a major issue and I can understand your enthusiasm for the Iwave devices. But cigarette smoke is particulate matter. VOCs, the issue I'm dealing with, are another animal altogether.
    Fresh air, carbon seem to work. Not so sure these standalone boxes are useful. Still searching though.

    BTW - IWave is branded product provided by Global Plasma Solutions ( I think)
