The guy who repaired my parents furnance suggested micro-biocide
filters. I usually buy the pleated type for them at Lowes or Depot
for about $15.00 a pop, but I don't know if they are treated or not.
He also suggested buying an electrostatic air filter unit which
attaches to the furnace for addtional filtration. From what I've read,
older homes or ducts (my parents house is 60 years old) aren't
designed to work well with these.Any suggestions? Thanks.

The Flanders Natural Aire are a much better deal than the $15 paper
ones.

As for internal air quality, opening a few windows daily all year does
more to improve indoor air than any filter, biocide, etc. can ever
hope to do.

I'll check out the Flanders Natural Aire. Thanks for the suggestion.

An electrostatic works fine in my 82 yo home. I can't think of any reason it
shouldn't work fine in any forced air system.

In fact I was told by an HVAC guy that older forced air systems often
had marginal ducts (as they were sized for heat only, while A/C requires
more airflow.) Therefore electrostatics are a good choice as they have
less airflow restriction than media filters.

Do you know what brands of elecrostatics are considered reliable?

Honeywell is what I've always had.
