We've never had much trouble with allergies in previous places we've lived. But after coming across your page about Sick Building Syndrome, I suspect our current old money pit of a house may be the cause of our allergy symptoms.

I am pretty sure our house is a sick building because I've noticed our allergy symptoms like fatique, sinus irritation, skin rash, runny nose, itchy eyes, sneezing, and headaches often decrease noticeably within a few days after leaving this home to visit relatives.

The basement of this old house smells musty and there is evidence of moisture and mold on the concrete floor and stone walls. The HVAC ducts throughout the house are also delapidated and dirty on the inside and I believe this is causing a big dust problem everywhere inside.

When air is blowing out of the duct vents there is also a strange odor like burning hair.My husband suspects the boiler in the basement may be poorly vented and fears Carbon Monoxide might be escaping into the basement. We have someone coming to check on the blower and pilot light this week and we plan on getting a quote to have the air ducts cleaned. Not sure how much that will cost but it won't be cheap.

I wish we could afford to scrap the entire HVAC system, ducts and all, and have a brand new modern air handling system installed. But unfortunately right now our finances are so strained that we have to make the best of what we have.

As far as the moisture and mold problem in the basement goes, a house inspector said it was very serious since it looks like Toxic Black Mold is on many surfaces and a mold spore test was off the charts. He suggested the installation of an elaborate outside drainage system plus an inside sump pump system in order to collect ground water that may still seap into the basement. This will be very very costly and I'm not so sure it will be able to stop the mold and mildew problem.

We also clearly have a rodent problem in the attic. My husband said it has obviously been a shangri la for mice up there and the bats also seem to be at home in their man-made cave. I am afraid of what diseases may be carried by these critters and what damage or fire hazards could result. So yet more worries to add to the long list of needed home repairs and renovations.

I asked him to do me a favor and do a little research at both of these hospitals regarding the number of times anyone has ever been admitted into either hospital suffering from over-exposure to Ozone caused by a home or room air purifier such as you have described.

Neither hospital has any record of anyone being admitted for this problem. In fact they do not even have an admittance category for "over exposure to Ozone gas". How would you explain this in light of your numerous warnings that I should avoid breathing ozone regarless of where it comes from? (Smog or electronic air purifiers)

Also I have read that ozone gas is always part of the air that we breathe outside our homes. Apparently, along the ocean and up in the mountains it is even stronger. Frankly, I and most people I know love ocean and mountain air! If there is ozone in the outside air why can't I have some inside my home. I'd love to have my house smell like ocean or mountain air! Especially since I see no evidence of people dropping like flies because they got over exposed to their Orick or Aran Air purifier?

What would you recommend I do?

Water, Microbile Enzyme Concentrate, Nonoxynol-10, Fragrance, Polysorbate 80.

Thank you for a very informative site."
