I am in the process of learning about fibreglass lined metal ducts, and its
an old house (early 80s).

So till I figure out what needs to be done and if we can afford it, is
there some kind of air filter we can use with our heating system (not the
portable room filter kind) to get rid of fibreglass particles if any.

I was looking at electrostatic filters, does this do the job ? Is there any
specific kind/brand one would recommend ?


Thanks
