Hello, the apartment I live in has had a bad mildew problem since I
moved in 2 years ago. It is a 3-plex, with a small studio apt. in the
basement. The owner had a mold removal company come out and look at
the problem. They suggested cutting back the landscape to get more
natural light, using dehumidifiers, and also removing the mold in the
crawlspace underneath the house.

Well the landlord did all of the above, but does not want to shell out
the $ to have the mold removed. He is trying to cheap out on this,
claiming the mold removal company only can guarantee their work for
1-year. He says that there was a couple of water leaks in both the
basement laundry room and the basement studio, and that he is also
going to put down another layer of plastic over the dirt in the
crawlspace.

He also wants to run an ozone generator for a few hours underneath the
house. Would it be necessary to remove my pets from my apt. if the
ozone machine is being run under the house, and how effective would
running it for only 6 hours be towards the problem?


thanks

Your landlord may have no choice. Check with your local authorities.
They may insist that proper mold removal be done. To be fair about this
there is mold and there is MOLD. Most mold is harmless, but ugly and
slinky. But some is harmful.

Ozone is nasty stuff. I would not want to be anywhere around where they
are going to pump enough in to attack a mold problem. I would not allow my
pets there either. Make sure everything is very well aired out after they
are done and before you and your pets return.

Good grief, Joe, where have you been? That's an uncharacteristic
answer from you, one of handful of knowledgeable posters here.
Sorry, I'm not trying to be confrontational; honest.

An ozone generator sized for the volume of the space, even
oversized pretty much, would not be a problem to pets or people.
It would however present the same problems for people that it did
for pets.
It's very unlikely to be any problem, but if the guy doing it
isn't a sensible person, the question might be: Is this an
approved generator, is it properly sized, and is it going to be
run per the requirements and usage stated in its paperwork?
EVERY ozone generator sold in the US and UK (I'm assuming the OP
is in the US) has to have approvals and has to include
instructions on using it.

From the FWIW department, ozone generators are the exact item
most motels and hotels use to keep their rooms fresh smelling.
They do a good job of covering cirgarettes and "people" odors.
You'l also find them in many of the better rest rooms in
restaurants, offices and many other places. And some of those
are run 24/7 but that's an exception.
Ozone is that nice, fresh smell you notice after a lighting
storm has passed.

Sorry; It's just that I was a compliance tester in a previous
life and tested thousands of them for the hotel/motel industry.

Yes, at low concentrations. At higher concentrations it's downright
nasty, and has been known to kill pet birds within 30 minutes.

If there's enough ozone to kill mold, then there's enough
ozone to be bad for you.

I think we are talking about two different kinds of ozone generators.
Some generate very small amounts and are designed for the kind of use you
refer to. They mostly just make the air smell like the after the
thunderstorm smell. Frankly I don't like even those amounts. While they
Ozone amounts may be legal, I don't like any additional to the background
already there. That stuff does bad things to all living things.

However I suspect the OP was talking about a far different ozone
generator. They may them with enough output to kill the mold and most any
other living thing in the area. Using the type you were talking about would
not really help with the OP's problem.

Note the following on your first referenced web page: "OZONE IS VERY
EFFECTIVE IN KILLING MOLD by the use of unoccupied room High Ozone Shock
Treatments. "

Note the word "unoccupied room" This is not what you would use in a
motel room to make it smell clean.

the op said the ozone generator was going to be run UNDER THE HOUSE in
the crawl space, not in the living area

Mark

Even ozone as air cleaners can cause lung problems according to
Consumer Reports when they last looked into this problem. A commercial
ozone generator could easily be several orders of magnitude greater
than the household units CR was evaluating - don't know without the
specifications. Ozone dissipates but could enter the house since it's a
gas. I would ask the local health authorities about quantities of ozone
and crawl spaces and what not. Short answer, keep all living creatures
away if using enough ozone the place to kill tough mold.

Since crawl spaces are usually pretty drafty you should be able to be back
into the house the next day. In any event, I would/ have opened up every
window in the house for a couple of hours to evacuate the residual gas. If
you have a hot air heating system, turn it on during the treatment in order
to treat the ducts and afterward, during the airing out phase, to distribute
clean air and assist in evacuating the ozone.
