Re: allergic reaction to flexible duct liner

[Guest guest]

I react to sacrificial metals shed by the heat exchanger in a

conventional furnace, or by the coil in a heat pump. Using the A/C

is not an issue as long as the coil stays wet.

I've also reacted to moldy dust in the ductwork of two homes here in

California (moisture from bathroom wasn't all captured by the fan,

some entered the duct and condensed in some dust).

I've also reacted to sacrificial metals from the boxes at both ends

of the duct, and to crud which had built up in the filter and was

escaping into the airstream.

Are you sure the reaction is to the duct liner itself? That kind of

plastics sensitivity is known in the MCS community, would be

accelerated by heat (could you mitigate it by running the fan at

higher cfm?), and would be really hard to get away from once the

person was sensitized. We heat with plug into the wall electric

heaters -- our winter electric bill is comparable to the cost of a

full duct replacement using flex ducting.

I am normally a person who stays in the background and reads the posts

that I find interesting. I have to comment regarding duct liners. My

field of investigation for the last 15 years has been Asthma and

Chemically Sensitive due to my own chemical injury working as an

engineer with Bellsouth which is again ATT. Just wanted to state where

I am coming from.

Duct Liners-my experience shows that if you are dealing with a person

who is Chemically Sensitive or Allergic to plastic that there is only

one way to go. Sheet Metal that has be cleaned of the oil film. That's

it, no alternatives. Do not waste your time experimenting with any

alternatives, there are none.

I know the next comment will be, " I can't afford it! " My answer is

always, " You cannot afford not to use sheetmetal " . Why did I made this

comment is always due to the old saying: Pay now or pay with allergic

reactions later. That's it, end of story. Thanks for listening.
