    There are several experts on this topic who lurk the newsgroup from time
    to time. One who does not, I believe is Phil Morey. He can be contacted
    at:

    Philip R. Morey, Ph. D. CIH
    Director of Microbiology
    Air Quality Sciences
    1337 Capital Circle
    Atlanta, GA  30067

    770-933-0638
    fx 770-933-0641

    Phil is among the best known in the field, because he has been a pillar
    of knowledge and strength on the ASHRAE Committee working on Standard
    62, which has wrestled with these issues extensively for the last 10
    years.

    Dear Matthew,

    I am a dealer for Alpine Industries. Our founder, Bill Converse, is an
    expert in just the topics you have mentioned. We have a lot of
    experience
    with growing various molds and mildews in ducts and rooms. If you have
    any specific question, I would be happy to find the answers for you.

    If you are interested in the products, you may purchase them, or you may
    become a dealer yourself.

    We have thousands of letters testifying to the benefits of our products,
    that destroy the mildews and molds. Our products make fresh air
    electronically. We call it a "thunderstorm in a box." A million people
    have one of our units and no complaints so far. We also do not have any
    competition in the field. Maybe that’s why we are selling $28 Million
    per month. (Success Magazine April ’97)

    If you would like some information let me know what you have in mind,
    and
    I will send it to you by mail.

    Sincerely,

    Osmo Joronen

    We have units for home and industry.

    Can you certify _zero_ ozone emmissions from your unit?  If you cannot
    you should provide a warning about this to people with asthma.

    I was recently at an expo where several Alpine Air units were being
    demonstrated and sold.  As I was walking down the aisle where they were
    [at the time not knowing they were thee], I started having problems breathing
    and started feeling VERY strange [not a normal asthma attack strange, this
    was more like hair standing strange, body feeling weird, which normally
    I don't feel 'cept around high voltage power lines or lightning].  The problems
    got worse the closer I got to the booth.  Once I got near the booth and could
    see it, I still hadn’t associated how I was feeling with it…  Since I saw
    the Alpine sign I figured I would go look at  the products.  BIG MISTAKE.
    Once I was within about 6 feet of the units, I started feeling a lot worse, and
    the strange feeling started to approximate that I’ve felt just before a nearby
    lightning strike.  The air smelt strongly of ozone and my lungs were NOT
    pleased.

    I left the booth.  An hour or so later, well after I was feeling well again, I
    happened back down that same aisle [without realizing it] and the same thing
    happened; again, walking in front of the booth was NOT a pleasant
    experience.  

    So, I know I certianly would never consider purchasing an Alpine unit, and
    hence they certainly would not get any complaints from me! :)

    Obviously, not everyone egts sick from these units as I do, but I am sure I
    am not unique on the planet.  In fact, I know I’m not, as others have
    complained of the same thing [deja news is your friend :) ].

    I do have a question regarding the no complaints claim:
    I recall that sometime in the last few years the federal government invesitgated
    Alpine or another similar dealer because of claims they made.  Was it Alpine?
    Why was the company [whichever co. it was ] being investigated?  What were
    the government’s findings??

    ..

    I am a satisfied Alpine customer.  I will not be without my machine in
    my living area because it stopped my breathing problems by cleaning up
    the air in the house.  

    There is a dial on the front of the machine with a note on the new
    machines that says that "MORE IS NOT BETTER".  When I can smell the
    ozone, the machine is dialed up too high, and just turn the knob
    counterclockwise to a new setting, and it is fine.  Also, the ozone
    demand varies slightly with temperature.  The warmer the room, the
    higher the setting before I smell the ozone.

    The friend who sold me the machine has an office with three people who
    felt a little light headed the first week or so when their machine was
    installed.  Then they were fine and have never felt better.  They
    figured out that they were DETOXIFYING that first week and their bodies
    adjusted with the mild cleansing from the better air quality the ozone
    produced.  I relate to that because I have had far fewer colds and flu
    symptoms in the two years I have had my machine.  It is doing something
    positive that I like.

    A booth where several Alpine machines are going at once can be
    overwhelming.  A ‘sick’ house with moldy ducts can be long term more
    overwhelming.  I would be selling these machines if I were not committed
    to another program.  They have turned my house into a ‘Colorado mountain
    air’ smelling environment year round.

    All the Alpine people I have run across give free trials.  If it doesn’t
    work for you, they will pick it up before you buy it.  BUT, if it does
    work for you, you will not let them put their hands on YOUR machine,
    ever again, It’s yours for better healthy living with no more moldy
    ducts.  

    I have logically concluded that trying one of these is a high percentage
    play on health. A small but very vocal minority will be GLAD to tell
    anyone who listens about any minor inconvenience they experienced with a
    product.  But the high percentage is from the people who have amazingly
    better living conditions and health from the results of living with a
    properly dial adjusted machine.  

    The only problem I have with the machine is in not buying it sooner.  I
    heard about these machines a long time ago, but the $600 retail was a
    put off until I started smelling the moldy ducts really bad.  Then I
    found a friend who sold it wholesale without becoming a dealer, and I
    installed it myself.  My local dealer now tells me they have financing.  

    My problem of moldy ducts is solved.  I hope you find your solution.
    Have a nice day.

    While I suspect that this device can be effective in cleaning the air
    and therefore can be quite satisfying to use, this kind of testimony
    could be dangerous. The satisfied user cannot comment on the long-term
    effects of exposure to dangerous levels of ozone on his lungs.

    I recall that a decade or two back it was admitted that more people
    were being found allergic to molds than to pollens.  However, I found
    allergists to continue to form their practices (often really gouging)
    90% based on pollens.  I’ve had allergic problems with molds in
    basement rooms I’ve inhabited in the past.  That may have been at
    least partially the cause of my later nasal mucosal atrophy, which no
    profession wants to do anything reasonable about.

    In the ’60s, I built a negative-ion generator per a magazine
    construction article.  Gave negative ions but did nothing for me, at a
    time when my nose didn’t work right, but when there probably wasn’t
    any mold-allergic effect on it.  In the ’70s, during these machines’
    fad days, I checked out some, with no useful results.  I assume
    producing such ions and passing air through a fine filter is all
    that’s involved in whatever you’re talking about here.

    Perhaps you had better clean out your air ducts and reduce/stop/cure the
    problem at the source. Not a stop-gap measure of filtration after the mold
    exits the ductwork.  Mold seldom becomes less unless it is stopped at the
    source or the condition causing the mold to grow is cleaned out.

    Many long term studies have been done to examine the long term effects
    of ozone exposure to the lungs. NO SCIENTIFIC STUDY has ever shown that
    ozone levels such as those produced by the Alpine units is harmful even
    to those with asthma. Check the medline, etc before you make comments to
    scare people. The facts are that ozone is very beneficial in a indoor
    sealed environment, and azone reacts, does not build up. The scientific
    literature points out that the pollutants which the ozone removes from
    the indoor air are much more dangerous than the ozone produced by the
    units.

    And no, I DO NOT sell the units. I do, however own one, happily so, and
    before I purchased it I did an exhaustive research for myself, not
    wanting to be influenced either by the salesman or the nay-sayers.

    What kind of breathing problems were these?

    Workplace exposure limits for ozone (based on a 40 hour/week exposure)
    are 0.1 PPM  Short-Term Exposure Limits (time-weighted average for 15
    min.) are 0.3 PPM.  IDLH (Imminent Danger to Life or Health) is 10
    PPM.

    In plain english, these limits are 1 part of ozone for every 10
    million parts of air for ‘everyday’ exposures, with 3 parts in 10
    million averaged over 15 min total for short term exposures.

    Now I do not know how well your nose is calibrated, but I suspect that
    by the time you can smell the ozone you are either near or have
    exceeded the ‘IDLH’ levels.

    BTW, how do these settings work?  Are they calibrated to a specefic
    ozone output such as 0.09 PPM?  Can you be sure that you are not being
    exposed to dangerous levels of ozone?

    I am not about to try any ozone-producing device.  I have asthma and I
    am aware that the numbers I posted above Do Not Apply To Me.  Ozone is
    right beside tobacco smoke as an ‘avoid at all costs’ item for
    asthamics.

    I Think we are missing the boat here. Abatment technology deals with the
    problem after it has occured. A trained IAQ evaluator will determine
    what of three factors are leading to a mold problem and will recommend
    remediation to eliminate the problem, not treat the by product of
    microbiological emissions after the fact with ozaone!

    Hear! Hear!

    Moreover, if you have microbiological emissions, that probably means you
    have microbiological life forms… which reproduce blindingly fast.  How
    much ozone would you need to control the microbiological emissions, which
    would likely be in parts per million?  Note that one ozone molecule will
    only react with one other molecule to oxidise the molecule and produce
    one molecule of oxygen.

    Cheers,

    The only way to deal with moldy air ducts is to fog them with Germ
    Stoppers.  This is a new way to purify the home and they use a solution
    that has been in hospitals for years.  Usually a pest control company
    is connected to this firm out of FL.

    Cheryl,
    I must agree that foggine with a product such as Oxine is effective in
    rapid control of mold, however we are still back to the basic problem
    that with in a short period of time a reinfestation will occur.
    Fiberglass duct work for instance is a haven for biological growth,
    foging and cleaning is a short term solution.

    There are three factors that effect the growth of microbiological
    contamination in an HVAC system.
    1> Food source, mold must have a food source such as dust or pollen
    2> Temperature, mold requires a specific temprature to grow
    3> Moisture, mold requires humidity greater than 60% on average.
    Address any one of the three key components and you are on the way to a
    permanent fix.
