Probably. Won't hurt to try. As you probably know, Ozone generators are used
to rid a space of smells from dead things and very dead things. A true
electrostatic generator inside an A/C return produces Ozone.
Ozone degrades into Oxygen fairly quickly (in minutes).

Google up Negative Health effects of Ozone and you will find alot of
studies that show you dont want to be around added ozone. Several gov
bodys have Ozone exposure limits that are specific in amount and time
of exposure. Most simply it oxidises your lungs and the effects can
easily be noticed by people with lung issues. For a vacant place its
ok but not for where you will live and breath it. Laundry bleach kills
mold, but you have to stop the leaks and conditions that are allowing
it to grow in the first place. It seems like you have mold, but you
are taking no action to correct the defects that are making mold a
problem. Even with a ozone generator, it may kill it now, but it will
come right back until you fix the problems
This is pretty much my understanding of it as well. Mold abatement isn't
accomplished by plugging in an appliance.
There is also the degradation of certain items from the oxidative ozone
molecule, which can release a plethora of toxic compounds into your living
space, and cause odors.
The unit is plugged in and the house is left unoccupied for a couple of days.
Upon return the unit is turned off and the house is aired out for a couple of
hours. Maximum exposure time to the ozone is maybe two minutes. It's
completely harmless if used properly.
It does kill all of the mold, but the underlying cause still needs to be
Yep. He's also completely ignoring that an Ozone generator requires a pure
source of oxygen, while what is commonly sold as an ozone generator produces
mainly NOx gasses that degrade a wide variety of synthetic materials.
Stopping all leaks and keeping humidity under 70% has worked for me,
if its in ductwork, it shouldnt be and there is a special light system
that can be used, I think its a UV system. But if its in ducts the
system isnt working as a properly designed and maintained system
should. Often a basement dehumidifier can fix all issues and new
energy star units are efficent mine costs about 4-6$ a month to run.
Thanks for the responses so far. This is the situation. Our ductwork
and central unit got flooded. We are going to replace everything.
However, we were told by one duct cleaning company that he saw mold.
So we of course got a little freaked out. Like I said we have since
decided to replace everything, but I am wondering how we can tell if
there is mold in the air and if so how can you get rid of it?
Provided it is th truth and not just a ploy for more business?
We have had tremendous fuss here about closing down schools/sending
students home etc. because of mould etc. It seems, IMO to have
followed all the super insulation and other energy saving techniques
of the last 30 years. And to boil down to stupid things like windows
that don't open, insufficient ventilation while several hundred active
children and staff are inside the building for some 7 hour per day
etc. Also improper understanding about vapour barriers etc.
All things that can be overcome/controlled by common sense
An allied concern throughout parts of NA was/is Legionnaires Disease,
unclean AC systems containing and maintaining disease spores and
seniors/veterans being more susceptible in later life.
A testing laboratory is the best solution for this. They will set
up a tripod in a suspect area and place a small unit with an air
pump and filter on it. The air pump sucks in a precisely measured
amount of air over a period of time, pulling it through the new,
sterile filter. The filter is then removed and sent to the
laboratory to be tested for the amount and type of spores found.
You'll get back a letter giving you a clean bill of health or a
letter telling you the problem and its intensity.
I have one I purchased from a Canadian manufacturer. It produces
5 GRAMS per hour and is a commercial-type unit. Unlike some folk,
I really like it, but use it sparingly. For instance, in a past
home, I had it controlled with a timer to come on 3 days or so
before we planned to return from a trip. I had it run for 24
hours and then let the ozone degrade for the 2 days before we
walked in the door. If there was any odor at that point, opening
windows for a few minutes took care of it, and the house would
then have a fresh scent. I never noticed any degraded items in
the house and certainly never breathed the ozonated air inside the
house when the unit had been run.
The units are used frequently here in Las Vegas at casinos and
restaurants to clean up the air from smokers. I've also seen them
used for brief periods in hotel rooms or aboard ships where
someone has sneaked a cigarette in the room or cabin, or following
carpet cleaning, with its musty smell.
Glad to. http://www.ozone.ca/products/home.html and it's the
Pro 5000. It uses 5 mica plates and seems to be well built. I
once needed to replace a mica plate and emailed the company. They
only sold them in sets, but the person at the company said he'd
send me just one- and it would be free. I told him I appreciated
it, but that I didn't want him to get into any trouble over it.
He replied that since he OWNED the company, it would be OK, and
thanked me for my concern. <grin>
That's the way to do it, if you're going to do it.
Ozone does kill mold spores, but it does not penetrate deeply. Mold
growing in carpeting won't be killed. If someone can come up with a
way to kill mold simply and safely without resorting to bleach,
scrubbing and a lot of labor, there won't be a bank big enough to hold
all of the money.
I agree. I like the Ozone generator to freshen up the house's
smell. We're in the process of locating a 1-story home to replace
our present 2-story one here. When we close on a new one, it's
going to get several days of Ozone before we even start moving
stuff in, and perhaps another day of it after the move, but before
we occupy the place. I also have used mine in the bathroom- first
running the hot shower for a few minutes, then giving it an hour
or two of ozone to kill smells and mold. It also works well in
the auto overnight.
