The company that came to clean our ductwork today found mold/mildew in the ducts and recommended a UV air cleaner to be placed in the air ducts - filters sterilized air throughout the house. Do you know anything about this?
Cost was $750!

Sounds to be a little strange because UV works when the germ passes over top of the light and it doesn't follow the germ in ducts. On the other hand an Ionizer (commercial grade) will remove the germs etc inside a closed in space because htey are forced by the air flow. Some air cleaners have ionizers on them but I would not recommend a home version because it may not work fast as you need them to work.

Most Hotels have a commercial version grade ionizers because when rooms become smoky the device will remove all germs including the smokey smells etc... The staff turns them on in the rooms for about 1 hour then remove the device. Commercial ionizers had a timer on them so it will not burn ones lungs due to the strength of the inonizer. I had one installed on our A/C system in our former home The air is ionized before it goes through the duct work and it does smell like a fresh air right after a thunderstorm and most specialists say that if a person stays in a room with the commercial grad device it can damage your lungs. We have not experience this and the smell of a home ionizer is just so very fresh....

If the worker detected mold/mildue inside the vents going to the heater/Air Conditioner unit then you will need to run the unit on FAN while the ionizer removes it. You should not remain in the home and it may take more than one session but I do not see how a UV light installed inside will do a better job...Find the source of the dampness and you may have it fixed after you ionize your vents.

Woah!! Mold and mildew in your furnace ducts implies you have a bigger problem than what a UV filter can cure. Mold/mildew and all the variant forms come from the same source: water and oxygen in close proximity to each other..

Find the source, cure the problem - if one actually exists. I think it is a ploy to con you into paying 4 times more for a UV filter that any furnace guy can install for a $150.

In the meantime go to your local hardware store and buy 3M American Lung approved furnace filters, Make sure the rating is 1200 or better. The higher the number the greater efficiency. Then change the filters every two weeks for a year. Your air will be as clean as any hospital. You will not have nearly as much stuffy noses, colds or the other assorted winter sicknesses.

I've been doing it for four years. No colds, allergy, or flu symtoms. The caveat is you cannot open the doors or windows at any time. If you do it invited mold in and defeats the purpose of the filter.
